Brazil’s Mineirão is the First World Cup Stadium Completely Powered by the Sun

Brazil’s Mineirão is the First World Cup Stadium Completely Powered by the Sun | Digital Sustainability | Scoop.it
An initiative by local electricity company CEMIG, Brazil’s Mineirão soccer stadium now features a whopping six thousand solar panels on its roof.
Digital Sustainability's insight:

While the world watches the nerve-racking matches being played inside, our eyes are completely dazed by what's going on outside the Mineirão stadium. This 1965 soccer stadium in Belo Horizonte was recently equipped with a whopping 6,000 solar panels on its roof just in time for the international competition. An initiative by local electricity company CEMIG, this is the first ever World Cup stadium completely powered by the sun.

Originally built in 1965, the public listed Estádio Governador Magalhães Pinto is one of this year’s World Cup venues. Topped with 6,000 rooftop solar panels, it doubles as a complete photovoltaic solar plant (USF) capable of supplying power to 1,200 households. The plant was built by the Minas Gerais State Electricity Company (CEMIG), in partnership with German bank kfW and Minas Arena, the group that manages the Mineirão.

Related: Brazil Cuts the Ribbon on Mineirão Stadium’s New $16.1m Solar Roof

Because the panels produce more energy than is necessary to power the stadium (1,600 megawatts-hour per year), 10 percent of the remaining power goes directly to regular consumers.

Although the Mineirão is the First World Cup stadium completely supplied by solar power, is not the first one in the world. This idea takes inspiration from Germany’s Freiburg and Switzerland’s Bern stadium, which also works thanks to the brightest star.

Digital Sustainability's insight:

$5.1 trillion dollars is one very big number. It’s a figure equal to just a little less than one-third of the U.S. economy’s annual GDP. $5.1 trillion is the amount that will be invested by 2030 to build new power plants that use renewable energy, according to a Bloomberg News Energy Finance report. Out of 5,000 gigawatts of power generation capacity to be added worldwide by 2030, renewable power will account for 4,000 gigawatts—nearly 80 percent of all new capacity. The leading technology in these new clean energy installations will be solar power, say the Bloomberg analysts. They predict that solar will be economically competitive with other power sources by 2020.

Falling prices for solar cells are making this power source a profitable business that doesn’t depend on subsidies for support. Decreasing prices for wind turbines are also driving the growth of wind power. Solar and wind power’s combined share of global generation will rise to 16 percent of the world’s total by 2030, up from its current 3 percent, predicts the Bloomberg forecast. And the report notes that this growth is taking place despite the downsizing of incentives for renewable energy from the U.S. and German governments. Since 2011, annual investment in renewable energy technologies has totaled more than the dollars invested in fossil fuel power generation. This upward trend for clean energy shows every sign of continuing to rise.

Green investors favor Apple after environmental reforms

Digital Sustainability's insight:

Apple Inc, criticized in the past for greenhouse gas emissions, use of toxic materials and the hiring of underage workers, has improved its practices and earned better scores from groups such as Greenpeace. That’s good news for environmentally-aware mutual funds that hold Apple for another big reason – it makes money.

The Cupertino, California-based maker of the iPhone, the world’s biggest public company by market capitalization, has adopted a slew of green policies such as expanded product recycling and using solar power at its data centers. For managers who have made it a favorite of the largest “green” mutual funds tracked by Thomson Reuters’ Lipper unit, the improvements bolster the appeal of a stock that’s risen 15 percent this year, 19th best among the Standard & Poor’s 100 index.

The confluence of a rising price and improving environmental performance make Apple “the one stock you just can’t ignore,” said Anthony Tursich, senior portfolio manager of the $498 million Portfolio 21 Global Equity Fund, a green fund that bought Apple in 2011 after the company began providing more emissions data.

Tursich’s biggest holding is Google Inc, which he bought only after it made progress on renewable energy, reflecting how top U.S. corporations are embracing green goals, and how the funds jump on those firms once they start making those environmental moves.

Environmental fund managers may be broadening their shopping lists in part because they have more money to deploy: For the 12 months ended April 30 investors put $1.9 billion of new money into the 72 funds tracked by Lipper that use environmental criteria in their investment decisions. That’s still tiny relative to the $247.6 billion that went into all U.S. equity funds, but represents a 5 percent inflow that Lipper research head Tom Roseen said was significant. The bulk of the new money, more than $1 billion, went into the dominant $9.5 billion Parnassus Core Equity Fund, Lipper said..

Google Self-Driving Cars May Get A New Laser Measurement System

Google Self-Driving Cars May Get A New Laser Measurement System | Digital Sustainability | Scoop.it
The Light-Radar (LIDAR) measurement system in Google’s self-driving cars is central to the drivability of the self-drive, since it identifies both the location and distance of relevant obstacles in real-time, thereby allowing the vehicle to avoid collisions as it moves across its appointed waypoint map.
Digital Sustainability's insight:

Part of the challenge associated with high-risk research and development is considering the cost of systems that evolve over time. It is difficult to create something ‘new and innovative’, when critical systems have never seen the light of product shelves either, and instead exist only as one-off components that may, or may not work the first time ‘round.

This is true in the case of the recently re-discovered Google’s self-driving cars, and particularly, its Light-Radar (LIDAR) measurement system. This component is central to the drivability of the self-drive, since it identifies both the location and distance of relevant obstacles in real-time, thereby allowing the vehicle to avoid collisions as it moves across its appointed waypoint map.

 

Currently the Google LIDAR system costs approximately $80k per unit. That would be an acceptable cost if Google’s development vehicles were likely to be used only in a purely closed-course basis going forward. But now, with the recent conclusion of a series of practical city-test agreements in California and Nevada, the nature of the test program will require more budget-minding, as the company’s heretofore prototypes begin to evolve toward more productized variants.

That said, however, a group of developers at UC Berkeley have come up with a ‘smarter’ approach to the challenge of real-time laser measurement, by proposing to eliminate Google’s current rotating electro-mechanical ‘top-hat’ system, in favor of what they refer to as frequency-modulated continuous-wave (FMCW) packaging. According to the group, the FMCW system will provide the self-drive with the same level safety measurement at a considerably lower price point.

Trucks Convoy under Computer Control to Save Gas

Trucks Convoy under Computer Control to Save Gas | Digital Sustainability | Scoop.it
A recent demonstration involving two trucks tethered by computer control shows how automation and vehicle-to-vehicle communication are creeping onto the roads.
Digital Sustainability's insight:

A pair of trucks convoying 10 meters apart on Interstate 80 just outside Reno, Nevada, might seem like an unusual sight—not to mention unsafe. But the two trucks doing this a couple of weeks ago were actually demonstrating a system that could make trucking safer and much more efficient.

While the driver in front drove his truck normally, the truck behind him was partly operated by a computer—and it stuck to its leader like glue. When instructed to do so, the computer controlled the gas and brakes to pull to within 10 meters (roughly three car lengths) of the truck ahead. The computer then kept the two trucks paired at this precise distance, as if linked by some invisible cable, until the system was disengaged. If the truck in front stopped suddenly, the one behind could have reacted instantaneously to avoid a collision.

Most automobile companies are working on full vehicle automation, but they need to overcome significant challenges before they can deploy those technologies (see “Driverless Cars Are Further Away Than You Think”). The technology demonstrated in Nevada, in contrast, could be deployed today, since the system is only partially automated (the driver behind still steers, with the aid of a camera that shows the view ahead of the truck in front). So it is covered by the same guidelines and regulations as adaptive cruise control, a feature in some cars that automatically keeps vehicles on the highway a safe distance from the ones around them.

This kind of “platooning”—as it is known—reduces the wind drag on both trucks, and could therefore save trucking companies millions of dollars in fuel every year. The trucks were fitted with technology developed by a startup calledPeloton Tech (“peloton” is the French word for platoon). Peloton’s system consists of radar sensors, a wireless communications system, and computers connected to each truck’s central computer. Video screens in both cabs show the drivers views of blind spots around the two vehicles.

Joshua Switkes, CEO of Peloton Tech, says the fuel savings are 4.5 percent for the front truck and 10 percent for the rear truck. This could amount to $100,000 each year. “For truck companies, these savings are enormous,” Switkes says. He adds that the technology could even allow competing companies to platoon together to get these savings.

Charging a Smartphone, No Wires Required

Charging a Smartphone, No Wires Required | Digital Sustainability | Scoop.it
A startup called Energous aims to let you charge your gadgets without plugging them in.
Digital Sustainability's insight:

“Do you want us to charge your phone?” George Holmes asks. Normally, that would be an odd question. But Holmes is the vice president of sales and marketing for Energous, a company that is developing technology called WattUp that will allow you to charge smartphones, tablets, and other small gadgets from across a room without wires.

Energous hopes other companies will license this technology and build it into all kinds of products and places, so you can easily power your iPad while sitting on the couch browsing Instagram, or top off your phone while buying a coffee or playing Candy Crush in an airport. It will face competition, however, from a startup called Witricity that uses a different method, and already has the backing of some major electronics companies.

For now, WattUp’s technology is still in the demo stage, which means it’s not very good-looking. But it works, and during a visit to my San Francisco office, Holmes wants to show it off.

Devices can be charged wirelessly if they are connected to an external receiver, or slotted into a special protective case. Holmes plugs my iPhone into a white device shaped like a smartphone atop a little stand. Another iPhone sits on the table, wearing a bulky Energous case. Across the table, a briefcase-sized wireless energy transmitter sits on another tripod and a plug dangling from it is plugged into the wall.

Holmes picks up an iPad running a WattUp app that shows the two devices that are enabled for charging—mine, and the other iPhone in the case. He taps the app to tell the transmitter to find the devices and start the power-up process. My phone, which is 53 percent full, buzzes to indicate it is charging. Recharging works more than 10 feet from where the power is emitted, and you can move the device around while it’s charging.

Energous is the latest in a long line of companies fixated on the idea that life would be easier if we didn’t have so many wires and gadgets to plug in. Yet many of the wireless charging products that have come to market have relied on special charging mats that juice up devices at a short distance, and they’re still not that popular with consumers. “There’s not very many people that want to take their phone and go leave it somewhere while it charges,” Energous CEO Stephen Rizzone argues. “If they’re going to leave it somewhere while it charges, they’re going to plug it into a wall.”

Digital Sustainability's insight:

Dr. Harry Atwater of Caltech is one of the world’s leading researchers ofApplied Physics and Materials Science, specializing in technology related tophotovoltaics and solar energy (1).   As director of Caltech’s Resnick Sustainability Institute, he is also the visionary and catalyst behind a new set of awards (the Resonate Awards) to recognize unsung heroes in scientific advances related to sustainability. Thomson Reuters Sustainability sat down with him to find out about this exciting initiative to bring daylight to breakthrough achievements in energy science and sustainability. Below are the Resonate Award winners for 2014:

2014 Resonate Award: A renewable power grid, when it’s not sunny or windy.

Dr. Atwater: Let’s start with Javad Lavaei who is an Assistant Professor in the Department of Electrical Engineering at Columbia University. He is receiving the 2014 Resonate Award for his work on incorporating solar, storage and other energy resources into the electricity grid in an efficient and cost-effective manner. Essentially, he has developed a robust system or model which would allow a diverse set of power generation and distribution without creating instability for the end user of electricity, even if the sun is not shining or the wind is not blowing. His grid model opens the door for a fundamental shift towards renewable power integration into our electricity grid. It also potentially moots the need for much of the energy storage and infrastructure planning which now exists.

Sustainability: How about Dr. Jaramillo?

2014 Resonate Award: Solar power for your gas tank.

Dr. Atwater: Tom Jaramillo is an Assistant Professor in the Department of Chemical Engineering at Stanford University. Tom’s award winning work focuses on taking carbon dioxide emission out of the process to produce liquid fuels for the trains, planes and automobiles we all use. His endeavors have led to the discovery of a catalyst for the production of hydrogen using solar power and very commonly occurring natural materials. Hydrogen can then be easily combined with other compounds to create liquid fuels and chemicals in a sustainable manner, improving the economics of renewable energy sources with the potential to replace petroleum-based liquid energy.

Sustainability: Please tell us about Shinichi Komaba’s achievement.

2014 Resonate Award: A super-battery for cars.

Dr. Atwater: Dr. Komaba is a Professor of Applied Chemistry at Tokyo University and a Project Professor at Kyoto University. He is receiving the 2014 Resonate Award for his research in the field of electrochemical energy storage and conversion, developing materials for sodium-ion batteries and safer lithium-ion systems. His breakthroughs in these systems show huge promise toward realizing zero-emission vehicles by developing new advances which allow for significantly smaller, safer and more energetic battery systems.

Sustainability: Please tell us about Jay Whitacre’s work.

2014 Resonate Award:A super-battery for houses.

Dr. Atwater: Jay Whitacre is an Associate Professor at Carnegie Mellon University and Founder and CTO of Aquion Energy. He is a really interesting character, as he works in both the policy and technology arenas. Professor Whitacre’s receipt of the 2014 Resonate Award honors his contribution to the grand challenge of finding safe, reliable, cost-effective, sustainable energy storage solutions. He developed a novel electrolyte battery technology based on low cost functional materials, which have the potential to be used for storage of massive amounts of energy at the electrical grid level. This breakthrough work helps to facilitate the introduction of renewable energy sources into the grid such as solar and wind, which require energy storage for when the sun isn’t shining or the wind isn’t blowing.

Sustainability: These kinds of advances have clear relevance for some types of investors, and their ability to drive change. Is that part of the idea behind recognizing the work of Ms. Kearney?

2014 Resonate Award: New funding for transforming the world.

Dr. Atwater: Yes. Ms. Sarah Kearney is the Founder and Executive Director of PRIME Coalition, a membership-based nonprofit that connects philanthropists and private investors to high-risk, high-reward startups that address climate change and other global social problems. Progress will be way too slow if funding for this kind of long-duration work continues to come from traditional sources like government and universities. Her work develops a philanthropic-venture marketplace which allows investors to identify and measure investment opportunities. It’s about connecting new pools of capital with high rates of return in an “energy breakthrough fund”, particularly focused on foundations and philanthropic organizations. It’s similar to the private equity and venture capital world, but with metrics around the effect desired on the world, and a financial return.

Sustainability: This is really exciting stuff!

Dr. Atwater: Now you know how I felt when reading the applications!   These are significant scientific applications which the world needs to know about.

New online sales tool for the efficient trading of solar projects to be showcased at Intersolar

New online sales tool for the efficient trading of solar projects to be showcased at Intersolar | Digital Sustainability | Scoop.it
New online sales tool for the efficient trading of solar projects to be showcased at Intersolar - Renewable Energy Magazine, at the heart of clean energy journalism
Digital Sustainability's insight:

The tool allows companies to upload and update details of the projects that they are selling via a user-friendly online input screen. Using a customized design, these projects are then published on both the company’s own website and on MilktheSun.com, one of the leading online marketplaces for existing PV installations.

This boosts the sales reach of each project and enables it to attract new groups of investors, MIlk the Sun says.

As a plug-and-play application, the sales tool is easy to set up and users are not faced with any complicated, time-consuming programming work, the company says. Milk the Sun adapts the tool’s design to the corporate website of each of its individual users, before sending them an HTML code for an iframe that can be integrated into their websites. The sales tool is then live. It’s as simple as that.

Milk the Sun has teamed up with industry experts to develop a practical, standard method of presenting and organizing project data online. This standard method is used for both Milk the Sun’s marketplace and the bespoke online sales tools. It is also used to create standardized data rooms, where supplementary information, such as contracts, plans and other documents can be stored.

“The new software solution was created at the request of numerous Milk the Sun partners. Thanks to it, companies can now trade projects in a proven and standardized format," says Felix Krause, CEO of Milk the Sun. "Potential business partners are able to view all installation details online, saving companies the hassle of creating and sending data heavy emails. This reduces sales costs and considerably increases the value of the entire website.”

The tool is currently available in English, German, Italian, Spanish and French.

The monthly user fee for the standard package is €100. A one-off fee of €2,500 is charged for customizing and setting up the online sales tool.

NASA Reveals the Unstoppable Rate At Which Antarctica Is Melting!

NASA Reveals the Unstoppable Rate At Which Antarctica Is Melting! | Digital Sustainability | Scoop.it

Digital Sustainability's insight:

Most of the doomsday predictions across the globe involve the oceans finally taking over land and if NASA’s latest reports are indeed true, that day may not be far off!

A NASA study looking at 40 years of ground, airplane and satellite data shows that the West Antarctic ice sheet is melting at a rate that is far above the normal projections and the damage done here is irreversible.

 

The West Antarctic-underbelly is indeed melting at a rate much greater than predicted by most climate change experts and NASA reveals that it might already be too late to avert future disasters.

While the process was started by carbon emissions and ozone depletion, it seems like a simple cut back in these will not stop it melting completely.

Scientists say that the West Antarctic ice sheet has already gone beyond the threshold point of disintegration and current reduction on carbon emissions can only help slow the melting down, but not stop it entirely.

 

“It does seem to be happening quickly and the system is in sort of a chain reaction that is unstoppable.

Every process in this reaction is feeding the next one,” said University of Washington glaciologist Ian Joughin, lead author of one study.

This is because the grounding line that stops these gigantic glaciers from complete damage has been already breached.

The team concentrated on the Thwaites glacier that has a huge impact on all the others around it and found that the ground data backed the satellite images.

This means the next few decades could see a surge in sea levels that will threaten low-lying areas across the globe even more.

World Cup 2014: 31 days of madness as the world’s most popular sport has its biggest event of the past four years.

We’re working on a couple of stories about solar and the World Cup that we’ll run over the course of the next month, but in honor of kickoff of this world-spanning event, below is a short look at how FIFA is working to make this event more environmentally friendly.

Before we start, let’s put the caveat out there that any event that requires hundreds of thousands of travelers to drive, fly or float thousands of miles is going to have an enormous carbon footprint. Not to mention even the waste generated by the event….

Putting that aside as much as we can, let’s talk about the environmental — and particularly the solar — upside to the World Cup.

Brazil Hosts The Most Solar World Cup Yet

While Brazil as a whole is not yet a solar powerhouse, a new report from Greentech Media lists the country as perhaps the most promising solar market in Latin America. GTM’s Latin America PV Playbook predicts that 2014 will double Brazil’s solar capacity — from 38.6 megawatts in 2013 to 72.6 MW this year.

A staggeringly huge chunk of that new generation is coming from solar-powered football stadiums. The British NGO Practical Action has put out a short report detailing just how much solar energy the World Cup can generate: 5.4 MW across four stadiums.

As Practical Action puts it, the 2014 World Cup will generate more solar energy than any previous World Cup, as well as more solar energy than many of the countries competing in the World Cup.

The chart below, from Practical Action’s double-duty World Cup bracket and energy poverty fact sheet [PDF], spells out the discrepancy between what’s happening in Brazil compared to the energy situation in many of the players’ home countries

Solar Cell Efficiency Rises By 30% Through Singlet Fission

Solar Cell Efficiency Rises By 30% Through Singlet Fission | Digital Sustainability | Scoop.it
Scientists were pretty excited when they discovered you could convert light energy directly into electricity by capturing photons in semiconductors, exciting them into “excitons” (bound electron with negative charge and hole with positive), and capturing the resultant current through electrodes. Now a group of four chemists from the University of California, Riverside, has worked out a
Digital Sustainability's insight:

It’s called “singlet fission,” and by using it, we should be able to boost solar cell efficiency by as much as 30%, providing “Third Generation” solar power. The Journal of Physical Chemistry Letters published the research results in an Editor’s Choice perspective article last month.

Christopher Bardeen, the chemistry professor whose lab led the research, explains what sent him  along this line of inquiry:

Our research got its launch about ten years ago when we started thinking about solar energy and what new types of photophysics this might require. Global warming concerns and energy security have made solar energy conversion an important subject from society’s point of view. More efficient solar cells would lead to wider use of this clean energy source.

“If a triplet exciton has half the energy of a singlet, then it is possible for one singlet exciton, generated by one photon, to split into two triplet excitons,” Dr. Bardeen explains. “Thus, you could have a 200% yield of excitons—and hopefully, electrons—per absorbed photon.”

Ljubljana wins European Green Capital Award for 2016

Ljubljana wins European Green Capital Award for 2016 | Digital Sustainability | Scoop.it
Slovenian capital Ljubljana has been named European Green Capital 2016 at a ceremony in Copenhagen, the current holder of the Green Capital title. Ljubljana was commended for raising environmental awareness amongst its citizens.
Digital Sustainability's insight:

Slovenian capital Ljubljana has been named European Green Capital 2016 at a ceremony in Copenhagen, the current holder of the Green Capital title. Ljubljana was commended for raising environmental awareness amongst its citizens. The jury also recognised its sustainability strategy 'Vision 2025', which brings together plans covering environmental protection, mobility, energy and electric transport.

In addition, Ljubljana has made significant progress in implementing green procurement policies covering 70 % of all city purchases.

Transportation in Ljubljana has changed dramatically over the past decade. From a city which was rapidly becoming dominated by the car, the focus has now shifted to eco-friendly alternatives. In 2013, Ljubljana modified the traffic flow within the city to limit motorised traffic and give priority to pedestrians, cyclists and public transport. Cycling is also increasing. By 2020 the city intends that public transport, non-motorised traffic and private vehicles should each account for a third of all transport.

Twelve cities applied to become European Green Capital 2016. Each entry was assessed by an international panel of 12 experts and five cities were shortlisted – Essen, Ljubljana, Nijmegen, Oslo and Umeå. All the finalists provided real-life examples of how respect for the environment, excellent quality of life and economic growth can all be successfully combined.

The European Green Capital Award is given to a European city that has a record of achieving high environmental standards, is committed to ambitious goals for future environmental improvement and sustainable development and can act as a model to inspire other cities.

Singapore, Denmark continue collaboration in building sustainable cities

Singapore, Denmark continue collaboration in building sustainable cities | Digital Sustainability | Scoop.it
The Centre for Liveable Cities and the Danish Architecture Centre ink new agreements to extend urban governance exchange programmes.
Digital Sustainability's insight:

The Singapore government through the Centre for Liveable Cities (CLC) has renewed its partnership with the Danish Architecture Centre (DAC), marking the continuation of the two countries’ collaboration towards building sustainable and liveable cities.

The agreement, which was signed on June 3 on the sidelines of the four-dayWorld Cities Summit in Singapore, looks to extend the urban governance exchange programmes that the two centres have started last year, a statement from the summit said.

The CLC runs various urban governance programmes for city leaders, policy makers, and urban planners who would want to gain more understanding about Singapore’s city planning model. Through its Leaders in Urban Governance Programme (LUGP), CLC teamed up with DAC, which also runs a similar programme called Strategic Urban Governance Programme (SUG). The exchange programme gave opportunity for local public officials enrolled in both programmes to participate in site visits to both countries.

CLC, which was established by Singapore’s Ministry of National Development and the Ministry of the Environment and Water Resources in 2008 and one of the main organisers of the summit, is involved in research and capability development on how to make Singapore a more progressive and environmentally responsible city.

Meanwhile, DAC is public-private partnership

 

About 65 government directors from Singapore and Denmark have benefitted in the exchange programme, the statement added.

The partnership also paved way fordialogues in Singapore with notable urban leaders, such as Copenhagen’s mayor of administration and chair of the culture and leisure committee Pia Allerslev and world-renowned architect and professor Jan Gehl, CLC said.

Subsequently, CLC hosted 19 Danish executives for site visits in Marina Barrage, the city-state’s largest reservoir, as well as the famous Southern Ridges nature park as part of the inaugural exchange programme. This year, 15 government officials from Denmark also participated in a study visit and attended the summit.

“Denmark and Singapore are two small countries, but they are both absolutely world-leading in terms of making cities liveable and more sustainable and a great inspiration for cities around the world,” noted DAC chairman Fleming Borreskov, adding that the agreement particularly strengthens the good relationship between CLC and DAC.

Copenhagen ranks high among global liveability indices, while Singapore tops in Asia in quality of living surveys. Both countries are also highly commended for its initiatives to promote efficient public modes of transport. 

During the summit, CLC also reaffirmed its research collaboration with the Urban Land Institute (ULI) on how communities can be made more liveable and presented the results of their collaborative research work on ‘Active Mobility’ with Jan Gehl. The research revealed that through careful urban planning, hot and humid Singapore can possibly implement a robust cycling and walking culture.

More than 130 participants, including mayors and city leaders, researchers and urban planners, discussed and debated what makes a ‘smart city’ at the summit, the organisers said - and reached a broad agreement that a smart city must be ‘green’ and should be sustainable and liveable.

between philanthropy organisation Realdania and the Danish government, which focuses on the development and dissemination of knowledge about architecture and urban planning. 

CLC executive director Khoo Teng Chye noted on the success of the programme and the strong friendships built among participants. “After the successful exchange programme for Singaporean and Danish directors last year, we are pleased to work with DAC on the second edition this year,” explained Khoo.

5 essential facts about emissions rules for power plants

5 essential facts about emissions rules for power plants | Digital Sustainability | Scoop.it
Confused by what the president's new climate rules mean? Here's the quick rundown.
Digital Sustainability's insight:

On Monday, President Obama unveiled the latest — and likely greatest — emissions reduction policy since he announced his Climate Action Plan last year: new rules to limit carbon dioxide pollution from existing power plants. With power plants accounting for around one-third of U.S. emissions, these rules will address the country’s single-largest source of greenhouse gas pollution.

Along with standards for new power plants, rules addressing methane emissions, and measures promoting energy efficiency, the forthcoming standards illustrate the way in which the president is using existing legislative authority to put the United States on a path toward meeting short-term and long-term climate commitments.

Unfortunately, there are a lot of misconceptions on what these standards are designed to achieve, the impact they will have and why they’re so important. This blog highlights some of the most important aspects of these crucial actions.

1. EPA has the authority and obligation to propose these standards

EPA is legally required to develop and enforce regulations to protect the public from air-borne pollutants under the Clean Air Act, which Congress passed with overwhelming bipartisan majorities in 1970, and further strengthened with subsequent amendments. Scientists agree that carbon pollution threatens American public health and welfare, and the Supreme Court affirmed in 2007 that the EPA has an obligation to protect the public from that threat. Currently we limit how much mercury, arsenic, soot and other air pollution power plants can dump into the air, but there are no limits on carbon pollution. EPA is doing now what it has done for decades — setting common-sense limits on harmful pollutants.

2. Transitioning away from uncontrolled coal is inevitable

Coal can be part of the future U.S. energy mix, but as the most carbon-intensive electricity source, it’s imperative that it rein in its pollution. Like other industries, coal can adapt by deploying technology to reduce its carbon footprint.

The U.S. power sector has been moving away from coal for years. It has accounted for only 5 percent of new capacity built since 2000, and only a handful of new coal plants are planned or under construction. Several of those will be outfitted with carbon capture technology.

Some pundits point to public health or environmental standards for the decline in coal industry jobs, but actually, the coal industry is using fewer miners to produce the same amount of coal. While coal jobs decreased by half since 1983, coal production in Kentucky and West Virginia held steady. New technology and techniques have driven this long-term trend.

The power plant rules also have the potential to create jobs in the efficiency and renewable industries. Studieshave shown that these industries support more jobs per megawatt-hour of electricity generation than fossil fuel industries.

3. States have many cost-effective carbon reduction opportunities

States are demonstrating that clean energy and efficiency policies create economic benefits and save electricity consumers money. For example, one study found that reducing Arkansas’s energy consumption by only 8 percent by 2020 would save consumers $1.8 billion, an average of $303 per household in that year. In Minnesota, the Department of Commerce found that the average cost of reducing electricity demand through the state’s Conservation Improvement Program is at least three times lower than building new generation from other energy sources. And studies by the Midwest Independent Service Operator (MISO) and the Illinois and Ohio Public Utility Commissions, among others, have found that increasing wind resources throughout the Midwest region will drive electricity prices down for customers.

4. America’s electric grid is ready for more clean energy

The grid is already able to handle more than 30 percent renewable generation in many places across the country. Over time, improved transmission and storage capabilities will allow for much more. Iowa, Colorado and Texas, for example, have absorbed a significant amount of new renewable energy supply in the last decade with no reliability issues. Furthermore, a recent report from the Analysis Group says that “reliability concerns are misplaced,” and that the president and EPA both acknowledge that emissions reductions from the power sector cannot jeopardize the reliable supply of electricity.

5. Other large emitters are already moving forward on climate action

Opponents of U.S. action on climate change often point to perceived inaction by other major emitters, notably China. Yet China is doing more to reduce its emissions than many realize. In 2013, China was once again the world’s No. 1 investor in renewable energy, with $54.2 billion, or 21 percent of the world’s total. And last year, China installed 12 GW of solar photovoltaic projects, 50 percent more than any country previously had installed in a single year. Other large emitters— such as Brazil and the European Union — are moving forward as well.

Many countries are waiting to see how determined the United States will be in setting reduction targets. A level of ambition that helps the United States meet its short-term climate goal (reducing emissions 17 percent below 2005 levels by 2020) and that lays out a longer-term trajectory for even deeper cuts will send a powerful signal to the rest of the world. It will show that the country is prepared to do its part in helping to avoid the worst impacts of a changing climate.

We need these rules to protect communities from climate change

In the face of increased sea level rise, dangerous heat waves and drought and costly extreme weather events, it’s clear that the impacts of climate change are already here. Significant emissions cuts are needed now to reduce the impacts we will see in the future. As the largest source of U.S. emissions, setting carbon pollution limits on power plants is a reasonable and essential step to address climate change.

With the right level of ambition, this new federal safeguard will not only curb power sector emissions. It also may spur the kind of innovation that will power America with clean energy in the 21st century.

Wood-waste biofuel to cut greenhouse gas and transform shipping industry

Wood-waste biofuel to cut greenhouse gas and transform shipping industry | Digital Sustainability | Scoop.it
A sustainable biofuel made from Norwegian forest wood waste could help transform the shipping industry and reduce global greenhouse gas emissions. Alternative sustainable fuels are urgently needed in the marine transport sector due to stringent upcoming regulations demanding reduced sulphur and carbon content in diesels and oils from January 2015.
Digital Sustainability's insight:

Aston University (UK) scientists are involved in the ReShip Project, which will use low quality wood waste, chippings and unmerchantable wood left in forests after logging has occurred to produce new biofuels. Via the process of fast pyrolysis, where material is heated in the absence of oxygen, the wood will be converted into crude pyrolysis oil. Compared to petroleum-based oil, however, crude pyrolysis oil cannot be used for direct use in diesel engines as it is too unstable.

To counter this, the Aston team, led by Professor Tony Bridgwater, will look to stabilise freshly produced pyrolysis biofuel through mild, rapid, low temperature catalytic hydrogen treatment. In cooperation with the Paper and Fibre Research Institute in Norway they will also seek to blend the bio-oil with conventional diesel and surfactant to form a multi-component fuel.

The most promising fuels will then be engine tested to assess their quality and use for potential marine transport.

Professor Bridgwater, Director of the European Bioenergy Research Institute at Aston University, said: “This project will establish a knowledge platform for cost-effective production of all new sustainable fuels which have the potential to completely alter marine travel. All of the wood sourced will be from Norwegian forests, which represent a significant resource for bioenergy production. There is a net positive increment in biomass in Norway – it is growing faster than it is being consumed.

“We hope to pave the way for large-scale biofuel production by 2020, in a way that is completely sustainable and doesn’t impact on land usage. Aston University’s experience in fast pyrolysis and biofuel production technologies for biomass and biofuel products will contribute considerably in making that goal a reality.”

In Scandinavia, fast pyrolysis oil production is rapidly becoming commercialised. Energy company Fortum is to invest €20m in an integrate bio-oil plant, while Swedish packing firm, Billerud, received €32m from the European Commission to build a new biofuel plant based on forest residues.

The ReShip project is being led by the Paper and Fibre Research Institute in Norway, who are partnered with Aston University and the Norwegian University of Science and Technology. The £321,000 project is funded by Norwegian industry partners and the Research Council of Norway and will run until 2017.

Solar Farmers in Japan to Harvest Electricity With Crops

Solar Farmers in Japan to Harvest Electricity With Crops | Digital Sustainability | Scoop.it

Japan’s campaign to boost renewable power supplies since the Fukushima nuclear disaster is producing some unlikely winners: vegetable farmers.

Digital Sustainability's insight:

Japan’s campaign to boost renewable power supplies since the Fukushima nuclear disaster is producing some unlikely winners: vegetable farmers.

Makoto Takazawa and his father Yukio earned 1.7 million yen ($16,700) last fiscal year selling electricity from solar panels that hang in a giant canopy above their farm east of Tokyo. The cash was almost nine times more than they made from the crops growing in the soil below.

Harvesting dual incomes from sunlight was a godsend to the Takazawas. They’re among the majority of Japanese farmers who depend on a combination of outside work, pension payments and government subsidies to make a living. The easing of land-use rules and mandates for utilities including Tokyo Electric (9501)Power Co. to buy clean energy at premium prices is poised to fuel the spread of panels to more farms.

“I was racking my brain to figure out what to do on this land that I’ll take over from my father one day, because growing rice and vegetables doesn’t bring in much money,” Takazawa said. “Then I heard about solar sharing for farmland.”

The government is dismantling a subsidy system that’s supported Japan’s rice production for four decades. The country is under increasing pressure from trading partners to roll back import tariffs of 778 percent for the grain, along with levies of more than 300 percent on sugar and butter.

Takazawa, 51, still works full time in machinery sales while his retired father, 78, tends the farm in Chiba prefecture most days. Sixty-eight more farms across Japan have approval to follow in their footsteps and set up solar panels, according to JA Group, the country’s biggest agricultural organization.

El frenado del metro carga coches eléctricos en veinte minutos

El frenado del metro carga coches eléctricos en veinte minutos | Digital Sustainability | Scoop.it
Train2Car es el nombre de un proyecto Innpacto del Ministerio de Economía y Competitividad que arrancó en 2011 con un presupuesto total de 2,1 millones euros para dar utilidad a esa energía sobrante.
Digital Sustainability's insight:

Con cada frenada del metro de Madrid, se obtiene energía que permite la carga rápida y de momento, gratuita, de coches eléctricos. Concretamente, en la calle Doctor Esquerdo, 48. Allí se encuentra la única metrolinera de España y una de las primeras del mundo, que aprovecha la energía cinética que se pierde al decelerar y la transforma en electricidad. 

Train2Car es el nombre de un proyecto Innpacto del Ministerio de Economía y Competitividad que arrancó en 2011 con un presupuesto total de 2,1 millones euros para dar utilidad a esa energía sobrante. 

Carlos Rodríguez, director de I+D de Metro de Madrid, explica a Sinc que “el sistema es pionero en el mundo”. De hecho, solo existe un programa piloto parecido en California, y se basa en la tecnología de acumuladores que la institución adquirió en 2004 a Siemens.

La firma alemana es uno de los integrantes del consorcio, liderado por Metro de Madrid, que ha desarrollado el prototipo. “Hemos operado como subcontratista nominado en colaboración con la empresa española SICA”, indica a Sinc Ricardo Sánchez Rebollo, responsable de electrificación ferroviaria de la filial española de la multinacional.

 

Energía cinética

“El acumulador de Siemens SITRAS SES, instalado en la estación de Sainz de Baranda, en Madrid, es una pieza clave. Su función básica es el almacenamiento de energía cinética generada por los trenes durante los ciclos de frenado y la devolución de esta energía almacenada cuando el vehículo vuelve de nuevo a acelerar”, explica el portavoz de la compañía.

Lo que quiso Metro de Madrid con Train2Car –añade– es sacar fuera este concepto con una metrolinera que pudiera reutilizar esta energía eléctrica remanente en la carga de vehículos eléctricos. Para ello, ha habido que adaptar la tecnología.

“Hemos tenido que hacer modificaciones en los niveles de tensión, en el tipo de corriente, la intensidad y cuidar mucho la seguridad y la protección de los usuarios porque las condiciones eléctricas cambian dependiendo del uso”, dice Sánchez Rebollo.

 

Carga rápida

El sistema permite una carga rápida en unos veinte minutos, frente a las varias horas que se tarda en los postes de corriente alterna.

En opinión de Sánchez, lo más innovador de la metrolinera es el aprovechamiento del excedente de energía del metro “para que en lugar de perderse pueda usarse como fuente energética alternativa”.

Otros integrantes de este proyecto Innpacto han sido la Universidad Pontificia de Comillas, que se ha encargado de realizar análisis, estudios, validaciones y auditorías, y el Centro de Investigaciones Energéticas y Medioambientales (Ciemat). Esta última institución ha desarrollado equipamiento y software de análisis para estudios y emulación en laboratorio.

Según Carlos Rodríguez, la fase de pruebas de la metrolinera finalizará el próximo mes de junio. Dependiendo de los resultados, podría extenderse a otros lugares de la red de metro de Madrid donde exista otro acumulador.

Los conductores de coches eléctricos pueden usar el punto de carga gratuito en la metrolinera entre las 8 y las 21 horas en un espacio cedido por la empresa Citroën, dice el responsable de I+D.

El servicio continuará siendo gratis hasta que acabe el periodo de pruebas el mes que viene. Metro de Madrid aún no ha decidido si empezará a cobrar a partir de ese momento.

Panasonic Targets Factory Rooftops for Solar Expansion in Japan

Panasonic Corp. is aiming to sell more solar panels specifically designed for the rooftops of factories and warehouses, a market it sees ripe with potential as Japan introduces rules that threaten to stymie the development of larger solar farms built on open land.
Digital Sustainability's insight:

Panasonic Corp. (6752) is aiming to sell more solar panels specifically designed for the rooftops of factories and warehouses, a market it sees ripe with potential as Japan introduces rules that threaten to stymie the development of larger solar farms built on open land.

Panasonic will start selling panels in June that are able to be installed more efficiently on corrugated factory roofing, Kazuhiro Yoshida, who heads the Osaka-based company’s solar division, said in an interview yesterday. The newer products are designed to more than double generation capacity by fitting more panels on a single rooftop, Yoshida said.

The Japanese electronics maker had been focusing on residential and small-size rooftops in Japan with its HIT-brand solar cells. The company is now adding a segment ranging from 50 kilowatts to 500 kilowatts in capacity, Yoshida said.

“Space is no longer left for mega-solar projects and you may encounter grid connection problems,” he said, referring to utility-scale solar projects typically of 1 megawatt or larger. “We expect middle-sized projects will expand rather than mega-solars,” he said. One megawatt equals 1,000 kilowatts.

A change announced earlier this year by Japan’s trade ministry may curb the expansion of utility-scale projects, Yoshida said. After finding hundreds of larger projects had been delayed, the ministry set a 6-month deadline for developers to secure land and equipment after getting approval, a requirement that is tougher for larger projects.

Solar Market

Japan’s solar market is expanding after the country began an incentive program for clean energy in July 2012. Japan will add 9,300 megawatts to 11,800 megawatts of capacity this year to become the second-largest solar market, according to a report by Bloomberg New Energy Finance in February.

Nonetheless, some Japanese panel makers are forecasting tougher times ahead as panel prices decline. Sharp Corp. is projecting a 5 billion yen ($49 million) loss at its solar unit for the year ending March 31, compared with a 32.4 billion yen profit a year earlier.

Kyocera Corp. this fiscal year forecasts a 9.6 percent profit drop at the business unit that includes solar products.

Panasonic said on April 28 that profit at its Eco Solutions unit is projected to fall due partly to declining panel prices in the 12 months ending March 31.

“Despite the booming Japanese market, competition among module suppliers is increasing, with Chinese suppliers offering the same product at a lower price,” said Takehiro Kawahara, an analyst with BNEF in Tokyo. “Module prices in Japan have historically been well above the global level, an unsustainable situation for a commodity product, and one which is being corrected,” he said by e-mail.

Digital Sustainability's insight:

Mercedes recently announced pricing for its first production-level all-electric car. The five-seat small luxury sedan, the B-Class Electric Drive, will go on sale this summer in the United States, with a starting price of $41,450—nearly an identical price to its primary competitor, the BMW i3.

Together, the two cars represent the new wave of luxury electric vehicles available in the U.S.—a market that has thus far been limited to the more expensive Tesla Model S.  As it happens, Tesla supplies the drivetrain and battery pack for the B-Class Electric Drive, which follows Tesla’s preference for sandwiching the battery pack between the floor of the car and the passenger space above.  The electric model is based on the conventional Mercedes B-Class, available in Europe and Canada, but coming to the United States for the first time.

The space configuration is one of the main distinctions between the B-Class and the BMW i3, which seats just four.  Another key difference is the i3’s optional range-extender, which allows that car to run on gas after its battery range is depleted.  The B-Class doesn’t offer the feature—which costs $4,000 extra on the i3.

Mercedes B-Class Electric Drive offers a range of 85 miles and can charge completely in about 3.5 hours on a 240-volt charger.

Both the B-Class and the i3 are way ahead of the pack of other small EVs in terms of performance. The B-Class nets 177 horsepower and 251 pound-feet of torque, while the i3 maxes out at 170 horsepower and 184 pound-feet of torque. By comparison, the Nissan LEAF is capable of just 107 horsepower.   The superb handling characteristics of the B-Class, and its interior fit and finish, are what you would expect from a Mercedes vehicle.

Mercedes will sell the B-Class electric in eight states to start: California, Connecticut, Maryland, New Jersey, New York, Oregon, Rhode Island and Vermont.  Sales in those states begin this summer, followed by the rest of the country sometime next year.

Thanks to the $7,500 federal tax credit for EVs, the B-Class can be had for $33,950—with residents of California and Marylandeligible for additional state credits of $2,500 and $2,000, respectively.  The B-Class also earns carpool lane access in California and New Jersey (which exempts EV buyers from paying sales tax on the purchase).
