Scaling Solar and Wind: A Hard Look At Innovation Priorities

Scaling Solar and Wind: A Hard Look At Innovation Priorities | Sustainable Energy | Scoop.it

If wind and solar have long-term ambitions of displacing fossil fuels as the dominant energy sources in America or the world, fundamental innovation challenges remain, the panelists stressed. Getting beyond 10, 20 or 25 percent shares for wind and solar though will require continued innovations to further reduce costs and address the challenges associated with the intermittent or variable nature of wind and solar energy output.

Atmospheric Vortex Engine

An atmospheric vortex engine (AVE) uses a controlled vortex to capture mechanical energy produced when heat is carried upward by convection in the atmosphere. A tornado-like vortex is produced by admitting warm or humid air tangentially into a circular arena. Tangential entries cause the warm moist air to spin as it rises forming an anchored convective vortex. The work of convection is captured with turbines located at ground level around the periphery of the arena. The heat source can be solar energy, warm water or waste heat.

Connecticut Auction Cuts Clean Energy Costs : Greentech Media

Connecticut Auction Cuts Clean Energy Costs : Greentech Media | Sustainable Energy | Scoop.it
In this first round of auctions, UI and CL&P solicited bids for large and medium ZREC projects and LREC projects of any capacity. The bids were expressed as prices for renewable energy credits that the projects would be assigned on the basis of one REC per megawatt-hour of electrical generation.

The bids were limited to $350 per REC for ZREC projects and $200 per REC for LREC projects. However, the utilities won't have to pay anywhere near those numbers for the 31 megawatts that the winning bidders will produce from their 97 projects.

The resulting RECs will cost UI and CL&P a total of $8.1 million annually, which works out to an average weighted price of $90 per REC – or far less than REC prices in many other states.

Sustainable Energy Roadmaps | Worldwatch Institute

Sustainable Energy Roadmaps | Worldwatch Institute | Sustainable Energy | Scoop.it

Transitioning from a carbon-intensive economy to a low-carbon future presents challenges and opportunities for developing countries. The Sustainable Energy Roadmaps help countries successfully navigate the change to an infrastructure capable of meeting the energy challenges of the 21st century.


The approach examines a country’s potential for renewable energy production such as wind, solar, small hydropower and biomass. Existing energy infrastructure is analyzed to identify the potential for, and hurdles to, increased efficiency and energy storage. At the same time, current socio-economic and policy environments are factored into the analysis to identify barriers to low-carbon development and determine international best practices to suggest how they can be overcome. Equally important, funding options that might be available from private, public, and multilateral institutions to help bring renewable energy projects into being are assessed.

The project strengthens government and civil society capacity, enhances stakeholder engagement, and advances policies that combat climate change...

Beyond the bluster: Why wind power is an effective technology

Much opposition to wind power appears to be based on the belief that it is an ineffective technology, inefficient or unreliable. This claim is untrue and it is important to get ‘beyond the bluster’ in assessing the effectiveness of wind power.

En captant l'humidité présente dans l'air, l'éolienne testée par l'entreprise Eole Water parvient à produire jusque 1000 litres d'eau par jour. Une innovation qui pourrait résoudre en partie les problèmes d'accès à l'eau potable.

 

On pourrait croire à un mirage, mais non. C’est bien de l’eau qui s’écoule en plein désert. Lors des premiers essais à Mussafah, à proximité d’Abu Dhabi (Émirats arabes unis), la jeune entreprise française Eole Water a concrétisé son slogan « Donnez-nous de l’air, nous vous donnerons de l’eau ».

Does a High Penetration of Solar and Wind Energy Cause -- Or Prevent -- Grid Instability?

Does a High Penetration of Solar and Wind Energy Cause -- Or Prevent -- Grid Instability? | Sustainable Energy | Scoop.it

Given that solar and wind are intermittent, our usual notion of these most common forms of renewable energy is that they create grid instability – perhaps even blackouts – stemming from unpredictable clouds covering the sun or changing patters in the winds in a given region.  But according to the Fraunhofer Institute for Wind Energy and Energy System Technology (IWES) in Kassel, Germany, these fears may be unfounded; when better understood, a high penetration of solar and wind may actually prevent power outages.

An intriguing story emerged last week about an Apple patent that has absolutely nothing to do with wireless gadgets, digital music, touch screens or the Internet “cloud”.

The title of the patent, filed in June 2011, is “On-demand Generation of Electricity from Stored Wind Energy.”

Wind energy? Apple? Don’t be so surprised. Like Google, another technology giant increasingly obsessed with clean energy, Apple operates huge data centres that consume tremendous amounts of electricity, much of it based on coal.

Ambitious Wind Farm Plan Unveiled | News

Ambitious Wind Farm Plan Unveiled | News | Sustainable Energy | Scoop.it
A scheme to build massive wind farms in Russia's Arctic northwest and sell the resulting electricity to Europe could kick-start the country's renewable energy industry.

 

The plan, dubbed RUSTEC, would see dozens of onshore wind farms built across the Murmansk region and plugged into a "power bridge" carrying the energy into the European grid via Norway or Finland.
It is the brainchild of the International Finance Organization, the branch of the World Bank Group that provides private sector financing for global development.
Supporters of the plan argue that low production costs and unusually high winds in the Russian Far North will produce efficiencies that actually make electricity generated there cheaper than renewable energy produced in Europe.
"I was inspired by DESERTEC — the plan to build solar stations in the Sahara desert in northwest Africa and transmit electricity to Southern Europe. I thought, why solar power from Africa, why not wind power in Russia?" said Patrick Willems, the project manager of the IFC's program to develop renewable energy in Russia.
Willems argued that onshore wind farms in places like the Murmansk region can generate more energy than expensive offshore plants in Europe. He added that, as Europe looks to meet its ambitious energy targets, it will pay handsomely for Russian wind power.

km-tech: Forecasting tool for energy efficiency

km-tech: Forecasting tool for energy efficiency | Sustainable Energy | Scoop.it

Balijepalli believes that an efficient power forecasting tool is extremely essential in today’s scenario when our country is facing a power crisis of the worst kind. And with the gap between demand and supply of power continuing to widen, the situation looks bleak. What it requires are drastic steps. Till the time that happens, an innovation like km-tech can be relied upon to ease the situation, as it will help the players in the power sector better manage their power needs and also save them some money in the process. Explaining the issues with the existing forecasting tools, he says, “The existing forecasting technologies face the drawback of using a large historian data before being able to predict to standard practical accuracy levels. Moreover, most of the existing technologies fail to capture the dynamics of even moderately irregular variation patterns of the variables, which are to be estimated. In order to attain these attributes some of these technologies tend to lose the golden property of 'Simplicity'. Extendibility to the future electricity grid environment and applicability to a wide variety of forecasting problems are the other major drawbacks.”

New study: There is enough wind potential on Earth's surface to power human civilization 100 times over

New study: There is enough wind potential on Earth's surface to power human civilization 100 times over | Sustainable Energy | Scoop.it

At the moment, wind power supplies about 4.1 percent of electric power in the United States. Still a bit player. Yet there’s a whole lot of untapped wind left in the world. Wind whipping through the Great Plains. Wind gusting off the shores. Wind circulating high up in the sky. So what would happen if we tried to harvest all of that wind?

 

We’d have enough energy to power the world. At least in theory. A new study published this week in Nature Climate Change finds that there’s enough wind potential both on the Earth’s surface and up in the atmosphere to power human civilization 100 times over. Right now, humans use about 18 terawatts of power worldwide. And, technically, the study found, we could extract about 400 terawatts of wind power from the Earth’s surface and 1,800 terawatts of power from the upper atmosphere.

 

Even the most optimistic near-term projections for wind power, however, tend to be more restrained. In 2008, the U.S. Department of Energy released a comprehensive report estimating that wind power could provide, at most, 20 percent of U.S. electricity by 2030. And for that to happen, the cost of wind power would have to keep plunging, the number of turbines built would have to steadily increase by about 14 percent each year, and utilities would have to build new transmission lines to accommodate the extra energy.

Skysails reduce fuel costs on-board by an average of 35%

Skysails reduce fuel costs on-board by an average of 35% | Sustainable Energy | Scoop.it

Benjamin Franklin used a kite to prove that lightning is electricity; The German engineer Stephan Wrage is using a kite to move really big ships. Inspired by two of his hobbies-kite-flying and sailing-Wrage realized that large kites could be used to pull freighters, thereby dramatically reducing fuel costs and producing fewer emissions. His SkySails kits reach more than 3,000 square feet and cost between $600,000 and $4 million, but can quickly pay for themselves-the largest can trim fuel costs by an average of 35 percent. One freighter, the MS Beluga SkySails, recently completed a 14,000-mile transatlantic voyage with a prototype computer-controlled kite, demonstrating potential savings of $2,000 a day in reduced fuel costs. The company looks to equip 35 more ships with kites in the coming year.
