Elon Musk: 'We need a revolt against the fossil fuel industry'

Elon Musk: 'We need a revolt against the fossil fuel industry' | Développement durable et efficacité énergétique | Scoop.it
Edie.net: Tesla chief says educating the public on climate issues is essential in countering oil and gas lobby’s influence over big political decisions
Stephane Bilodeau's insight:
“The fundamental issue with fossil fuels is that every use comes with a subsidy,” Musk said. “Every gasoline car on the road has a subsidy, and the right way to address that is with a carbon tax.” (...) 
The business magnate therefore believes that educating the public on climate issues will be essential in reeling back the fossil fuel industry’s influence over big political decisions – which has already led to European climate policies being dropped over fears of a mass exodus.

 “It is quite worrying, the future of the world,” he added. “We need to appeal to the people and educate them to sort of revolt against this and to fight the propaganda of the fossil fuel industry which is unrelenting and enormous.”

COP 19 conference: a key step in the fight against climate change

COP 19 conference: a key step in the fight against climate change | Développement durable et efficacité énergétique | Scoop.it

Sea levels and air temperatures continue to rise according to studies, which is expected to lead to more floods and worse heat waves. To help prevent this, the 19th UN Climate Conference takes place this month to discuss how to curb carbon emissions after 2020, including key steps towards a new globally binding agreement by 2015. Check out the infographic on climate change for more information.

In the Climate Change Economy, It's About Efficiency, Not Just Growth

In the Climate Change Economy, It's About Efficiency, Not Just Growth | Développement durable et efficacité énergétique | Scoop.it

North American cities are producing substantially less wealth per ton of greenhouse gas emissions than their European counterparts.


Research has shown that if you know a country's GDP, you can pretty accurately estimate its carbon emissions. There's "almost a mechanical relationship" between the two. And as a depressing corollary: Emissions rise much faster in good times than they fall during, say, a global recession.

Cities in some parts of the world are already doing a substantially better job at decoupling these two trends than others, wringing the most wealth out of the smallest carbon footprint. These are the cities that produce the greatest amount of GDP per ton of greenhouse gasses emitted.


The Carbon Disclosure Project, along with AECOM and the C40 Cities, have calculated this "economic efficiency" for dozens of global cities that participated in a questionnaire on how they are preparing for climate change...

9 Steps Cities Must Take to Dramatically Cut Carbon Emissions

9 Steps Cities Must Take to Dramatically Cut Carbon Emissions | Développement durable et efficacité énergétique | Scoop.it

A very long, very bold to-do list for the next 20 years.

The city of Toronto has already begun to sketch out policies that could reduce the area’s greenhouse gas emissions in the coming decades. Officials have proposed greening the electric grid, banning incandescent light bulbs, promoting green roofs on commercial buildings, retrofitting 1960s-era high-rises and implementing a stricter energy-efficient building code for new construction. With transportation, the city wants to expand bike lanes and transit infrastructure, all while it anticipates that electric vehicles will grow slowly more common.

This is a pretty standard menu of ideas, and according to scientists it will get the city part of the way toward the kind of changes broadly needed to really keep global temperature rise below 2 degrees Celsius.

But to really alter the future prospects for climate change, much more will have to happen in Toronto, and every other city. Researchers used the city as a case study to model what a truly aggressive framework might look like. If Toronto wants to cut emissions by 70 percent by 2031, all of these actions (or others with a similar impact) might be required in tandem...

While the steps being proposed in Toronto may not be as aggressive as those recommending by researchers concerned with reversing the climate changes caused by humanity's activity, they are at least a step in the right direction and far more than what seems likely in most U.S. cities.

Green and Healthy Buildings: monitoring consumption & ecology in the built environment

Green and Healthy Buildings: monitoring consumption & ecology in the built environment | Développement durable et efficacité énergétique | Scoop.it

According to the United Nations Environment Programme, buildings account for approximately 40 percent of worldwide energy use and are responsible for 30 percent of greenhouse gas emissions. They also play an important role in the health and wellbeing of those who inhabit them each day.

The mass of information about what makes a building green tends to concentrate on new and innovative designs that create beautiful photo spreads. While such examples are inspiring, they make up a very small percentage of all buildings in operation.

Green Buildings Alive is an environmental initiative aimed at collecting and sharing data on existing buildings between 10 and 60 years old. The data is collected from office towers in Australian Central Business Districts (CBDs) and shared on a public website.


For more on this innovative, environmental initiative that provides interactive visualizations of building-performance data to help understand the complexities and relationships among sustainability, health, and energy, read the complete article

Denmark Is About To Set Even More Ambitious Climate Goals Than All Of Europe

Denmark Is About To Set Even More Ambitious Climate Goals Than All Of Europe | Développement durable et efficacité énergétique | Scoop.it
Agreement in Denmark's parliament cleared the way for a legally binding greenhouse gas emission reduction target of 40 percent below 1990's levels by 2020.

 

The bill would establish a legally binding requirement that Denmark cut its greenhouse gas emissions by 40 percent below 1990′s levels by 2020, and that the government return to the question every five years to set new 10-year targets. The legislation would also establish a Climate Council — modeled on a similar body in Britain — to advise the government on the best ways to continue reducing Denmark’s reliance on fossil fuels.

Denmark’s present and former governments have already committed the country to a goal of 100 percent renewable energy generation by 2050, and the new bill is seen as a concrete step to achieving that goal.

Stephane Bilodeau's insight:

Meanwhile, Denmark has already been making substantial progress on the climate front.According to numbers that Responding to Climate Change pulled from the Danish Energy Agency, renewable energy accounted for 43.1 percent of Denmark’s domestic electricity supply in 2012, and for 25.8 percent of all energy consumption in the country that year. The year before that, renewables provided 23.1 percent of Denmark’s electricity consumption.

California's Unusual Plan to Cut Greenhouse Gases

California's Unusual Plan to Cut Greenhouse Gases | Développement durable et efficacité énergétique | Scoop.it

The state is relying on cities to figure out how to cut emissions in their region. Will it work?

 

When California’s S.B. 375 was passed in 2008, there were many skeptics. The law aimed to get metropolitan regions around the state to cut greenhouse gas emissions through changes to development form and transportation. 

In 2011, the California Air Resources Board set GHG emissions reduction targets by metro region for passenger vehicles and 18 Metropolitan Planning Organizations were then to develop "sustainable community strategies," with integrated transportation, housing, and community development.

The idea was that smart, sustainable community design, coordinated with transportation systems that integrated walkability, bicycles, and next generation public transit, could really make a difference. It's honestly much too soon to tell whether this will work. But here's a quick look at three prominent metropolitan regions and their responses to this mandate.

Wooden Skyscrapers: A New Level of Sustainability?

Wooden Skyscrapers: A New Level of Sustainability? | Développement durable et efficacité énergétique | Scoop.it

A new breed of high-rise architecture is in the process of being born, thanks to the collaborative efforts of modern design pioneers. Envisioned as the best sustainable option for meeting world housing demands and decreasing global carbon emissions, wooden mega-structures are now one step closer to becoming a reality.


“Big Wood,” a conceptual project to the eVolo 2013 Skyscraper Competition, builds on the premise that wood, when harvested responsibly, is one of the best tools architects and engineers have for reducing greenhouse gas emissions and creating healthy communities. Aspiring to become one of the greenest skyscrapers in the world, Big Wood challenges the way we build our cities and promotes timber as a reliable platform to support tomorrow’s office and residential towers...

The Case For Tall Wood                               Michael Green Architecture

I find this hard to truly picture, but the story is solid...."the last century there has been no reason to challenge steel and concrete as the essential structural materials of large buildings. Climate change now demands that we do.....Wood is the most significant building material we use today that is grown by the sun. When harvested responsibly, wood is arguably one of the best tools architects and engineers have for reducing greenhouse gas emissions and storing carbon in our buildings."

 

“I’d put my money on solar energy…I hope we don’t have to wait till oil and coal run out before we tackle that.”
~Thomas Edison, In conversation with Henry Ford and Harvey Firestone March 1931

“Known as the birthplace of the skyscraper, Chicago is an optimal location for a prototype in mass timber construction,” writes Carlos Arzate

Fascinating place. Must of been a lot of wood to be created.

Bubba Muntzer's comment, May 13, 2013 11:44 AM
It takes around 30 years for a seedling to grow into the kind of wood that can be used in construction. A little maintenance is required during that period. Meanwhile it's soaking up CO2 and making oxygen. The only industrial processes required are to cut it down and cut it into boards and 2 x 4s. If you stagger your planting you have an endless supply.

Watch 62 Years of Global Warming in 13 Seconds

Watch 62 Years of Global Warming in 13 Seconds | Développement durable et efficacité énergétique | Scoop.it

An amazing 13-second NASA animation depicting how the globe has warmed during the period of 1950 to 2012.


From our friends at NASA comes this amazing 13-second animation that depicts how temperatures around the globe have warmed since 1950. You’ll note an acceleration of the temperature trend in the late 1970s as greenhouse gas emissions from energy production increased worldwide and clean air laws reduced emissions of pollutants that had a cooling effect on the climate, and thus were masking some of the global warming signal.

 

The data come from NASA's Goddard Institute for Space Studies in New York (GISS), which monitors global surface temperatures. As NASA notes, “All 10 of the warmest years in the GISS analysis have occurred since 1998, continuing a trend of temperatures well above the mid-20th century average.

The Hestia Project Maps Carbon Emissions of US Cities Down to Street Level

The Hestia Project Maps Carbon Emissions of US Cities Down to Street Level | Développement durable et efficacité énergétique | Scoop.it
A team of researchers from Arizona State University have developed a new software system, called Hestia, that is capable of estimating greenhouse gas emissions across entire urban landscapes, all the way down to street level and individual buildings.

The project, known as Hestia after the Greek goddess of home and hearth, allows the team to combine extensive public database “data-mining” with traffic simulation and building-by-building energy-consumption modeling.

According to researchers, Hestia’s increased detail and accuracy will help cities, and possibly even other nations, identify where an investment in energy and greenhouse gas savings would have the greatest impact...

Energy Land(ing)-scape | Calderara di Reno Italy

This project seeks to find a effective balance between two principal necessities: to redevelop and revitalize the area, with a strong ecological impact on surrounding territories. The solution was to transform the area into a ZEA: Zero Emission Area.

A ZEA promotes the area and seeks for investments and a new economical initiatives to transform an area into a environmental zone. The project consists of a solar roof installed over the existing warehouse’s roofs and over the outdoor areas, including parking, producing clean energy, reduces emissions, collects water and gives a new image of the region to all people that are taking off or landing in the close Airport of Bologna.

The project seeks to give new life to this area from an economic point of view, as well as to demonstrate how development can have a positive ecological impact.
