An aide to Obama said Friday that the administration plans to add 20 gigawatts (GW) or more of wind power and 4 GW of geothermal and solar power by 2012 through loan guarantees and fast tracked national renewable energy requirements, like the Renewable Portfolio Standard. Last May the U.S. Energy Department estimated wind power could provide almost a quarter of U.S. electricity. Trade groups from the U.S. wind and solar industries were happy with the news, considering that the current economic environment for commercial credit has lowered all boats as it were, with all investment now endangered - not just investment in risky financial instruments, but even those investments in renewable energy that are essential to growing a stable economy. 4 votesBuzz up! No other country, in any single year, has added the volume of wind capacity that was added to the US electrical grid in 2007 with both wind and solar growing well over 40%, but with the credit crunch affecting all sectors of the economy, new projects could drop by as much as 50%, without help from the Federal government.

Energy Matters has a post on a new solar PV farm in Portugal - Portugal's Largest Solar Farm Opens. Portugal's Acciona Energy recently opened the country's largest solar power farm, executing the construction of the project in a record time of 13 months. The solar farm covers an area of 250 hectares in the municipality of Moura (Alentejo region), near the border with Spain. The AUD$571 million 48 MW facility will provide power to over 30,000 Portugese households; producing 93 million kWh of electricity annually and avoiding over 89,000 tonnes of carbon dioxide emissions compared to a similar output via coal fired power generation.

The Guardian has a report on some new tidal power technology from a company in Wales inspired by ship propellers and wind turbines - Tidal power gets a boost from propeller and wind turbine techonology. Propellers on ships have been tried and tested for centuries in the rough and unforgiving environment of the sea: now this long-proven technology will be used in reverse to harness clean energy from the UK's powerful tides. The tides that surge around the UK's coasts could provide up to a quarter of the nation's electricity, without any carbon emissions. But life in the stormy seas is harsh and existing equipment - long-bladed underwater wind turbines - is prone to failure.A Welsh renewable energy company has teamed up with ship propulsion experts to design a new marine turbine which they believe is far more robust.

A MAJOR criticism of wind farms is that they are intermittent. Wind does not blow consistently and, as a result they do not provide a continuous supply of power, but must be backed up by conventional fossil fuel plants. However, a renewables firm believes it has hit on a solution, and is hoping to use it in Scotland. A hydrogen plant would store energy from the wind farm, creating a reserve that could be dipped into on demand, so that even when the wind was not blowing, an electricity supply would be available.

Recently the town of Heerlen in the Netherlands repurposed an old abandoned coal mine into a brilliant source of geothermal energy. The project takes advantage of flooded underground mine shafts, using their thermal energy to power a large-scale district heating system. Dubbed the Minewater Project, the new system recently went online and provides 350 homes and businesses in the town with hot water and heating in the winter and cool water in the summer.

The Age recently had an article on the emerging practice of "guerilla gardening", taking a look at the "Gardening guerillas in our midst". This concept seems to have steadily increased in popularity in recent years (admittedly from a very low base) as the permaculture movement's ideas have been propagated through the community. Unlike the usual approach taken when trying to grow food in the suburbs - converting spare land on your own property (as discussed by aeldric previously and, more recently, in Jeff Vail's series on A Resilient Suburbia) - guerilla gardening involves cultivating any spare patch of urban land that isn't being used for another purpose, which could provide a substantial addition to the food growing potential of suburbia.

More than 100,000 people attend; a testament to the popularity of sustainable building and renewable energy in the region. by Michael Fell Wels, Upper Austria [RenewableEnergyWorld.com] Last week saw the return of the World Sustainable Energy Days conference which is held every year in Wels, Upper Austria. Taking place over three days (plus a day of site visits), the conference has three main streams: the European Pellet Conference, the European Energy Efficiency Conference and Regional Biomass Action Plans. Austria is an apt location for the conference - along with Sweden it is well known as one of Europe's biggest users of pellet technology - and as the final remnants of this year's snow melted away it is plain to see why. With cold winters and real enthusiasm for efficient and sustainable building, the demand for renewable heat is strong. The country is also highly forested, providing ample raw material for pellet production in the form of sawdust and wood shavings from sawmills (along with other biomass waste).

Scientists at The Nature Conservancy in Montana have completed the first analysis of where wind generation facilities can be located with minimal risk to the state's wildlife and the environment. Wind provides great promise for a clean and renewable source of energy, but each year wind generation facilities kill tens of thousands of birds and important pollinators such as bats. . And yet, wind energy development has moved forward with very little science-based analysis that might help prevent this kind of environmental harm. The impacts of wind generation are greater than just the immediate airspace. Most turbines take up 40-100 acres of land, so large-scale wind farms can span thousands of acres. Each facility also requires roads and transmission corridors.

The 25-percent-by-2025 renewable electricity standard bill introduced today by Rep. Edward Markey (D-Mass.) and Rep. Todd Platts (R-Pa.) would boost renewable energy generation by 135 percent above and beyond current policies between now and 2025, according to the Union of Concerned Scientists' preliminary analysis of the legislation. "This electrifying standard would provide a smart, proven, cost-effective strategy to ramp up our clean energy use, create tens of thousands of jobs, and lower consumer utility bills," said Alan Nogee, UCS Clean Energy Program director. "The clean energy tax incentives that Congress is finalizing will get us moving in the right direction in the near term, and the renewable energy standard makes sure we stay on that path for the foreseeable future."

CleanTechnica has a post from San Francisco mayor Gavin Newsom on the city's proposal to build a wave power plant offshore - Wave Energy to Bring Power and Jobs to San Francisco. Today, San Francisco took a meaningful step toward turning the promise of renewable ocean energy into reality. We submitted a preliminary permit application to the federal government to develop a wave power project off our coast that we believe can generate between 10 to 30 megawatts of energy, with potential of up to 100 megawatts. When this project is fully operational, upwards of 100 jobs could be created in San Francisco. Ocean power is a true "game changer" in the area of renewable energy. When wave and tidal power technologies reach commercial scale, they are expected to be able to provide thousands of megawatts of power to our coastal communities, dramatically green our energy portfolios and create thousands of new American jobs. In San Francisco, we've been doing our part to spur these technologies by aggressively advancing tidal and wave power pilot projects. We are 100% committed to this challenge. Wave power is not a new concept. In 1887, San Francisco Mayor Adolph Sutro recognized the power of San Francisco's waves and built a wave catch-basin to harness the ocean's power. Over the next century wave power development took a backseat to our dependence on oil, with oil platforms built along our coasts to feed our oil addiction.

REW has an article on making the switch to a clean energy world - Will the Children of Today Be Living in a World Powered by Renewable Energy by 2050?. The world needs a one-off switch-over to renewable energy -- and this could be largely accomplished in just forty years time, slashing energy costs and greenhouse gases while allowing healthy economic growth, experts say. By 2050, 80 percent of the world's electricity could be coming from renewable energy sources provided efforts are made, in parallel, to improve energy efficiency, according to a study by the German Aerospace Center (DLR). That means, the children of today might well grow up to experience a world where the energy they use comes almost entirely from the sun, wind, sea and biomass. By 2090, the shift to renewable energy around the world could be almost 99 percent completed reducing pressure on the environment and laying the foundations for a new era of prosperity based on green energy.

If you don't feel like trying to go back to school, or maybe school is not for you, try vocational schooling.

The sun blasts Earth with enough energy in one hour-4.3 x 1020 joules-to provide all of humanity's energy needs for a year (4.1 x 1020 joules), according to physicist Steven Chu, director of Lawrence Berkeley National Laboratory. The question is how to most effectively harness it. Thin-film solar cells may be the answer: One recently converted 19.9 percent of the sunlight that hit it into electricity, surpassing the amount converted into power by mass-produced traditional silicon photovoltaics and offering the potential to unleash this renewable energy source.

A very good article providing possible market based solutions to the climate crisis. Introduced by Tyler Cowen of Marginal Revolution.

Washington, DC-Nevada Senator Harry Reid joined other Democratic senators at a press conference today to unveil the Consumer-First Energy Act of 2008, a bill that addresses the root causes of high gas prices. Seven years of the Bush Administration's disastrous energy policies have enriched Big Oil and market speculators at the expense of American consumers. Democrats are committed to providing relief to consumers and strengthening our economic, energy and national security.

For every creature a home is an important factor. It provides protection from predators and affords shelter from the elements. Birds, in particular, devote considerable time to creating a suitable abode. The vast majority build their own nests, although there are some exceptions. For example, some owls use a hollow in a tree , and most falcons and nightjars dispense with a nest altogether and lay their eggs on bare earth.

California's utilities are in a tight spot. They're mandated to procure 20 percent of their electricity from renewable resources by the end of next year. Currently, renewable energy provides only 12 percent of the state's needs. Green energy is needed, and fast. Where to get it? The southeastern corner of California is becoming the state's Wild West of renewable energy. Five years from now this patch of desert will hold one of the largest solar thermal plants in the world. An area of 10 square miles will be filled with 38,000 "sun catchers," which look like enormous satellite dishes with mirrors.

Can you explain to me and the readers why solar panels are so expensive? Why can we not get the cost of this energy down to US $0.15 per kWh while we're paying off the equipment? Why are we paying for future production capability today? It is like the current electricity providers are saying, "Well, your house will use 12,000 kWh this year so we want our $1,800 now" or worse "give us 20 years up front" as the solar industry does today! If the solar market really wants to see a green planet then I feel they need to get the green out their eyes! Can they not see that they can truly make every home owner self sufficient if they bring their costs in line. It seems as though this renewable energy game is for the wealthy. If I want my home to be totally self-sustaining, it would cost me $80,000! A: Ian, I am happy to respond to your question since I have spent my own money on both my net-zero-energy home and my zero-energy office building - so I am acutely aware of the costs.

Vice President Joe Biden and Energy Secretary Steven Chu today announced plans to invest $3.2 billion in energy efficiency and conservation projects in U.S. cities, counties, states, territories, and Native American tribes. The Energy Efficiency and Conservation Block Grant program, funded by President Obama's American Recovery and Reinvestment Act, will provide formula grants for projects that reduce total energy use and fossil fuel emissions, and improve energy efficiency nationwide. "These investments will save taxpayer dollars and create jobs in communities around the country," said Vice President Biden. "Local leaders will have the flexibility in how they put these resources to work - but we will hold them accountable for making the investments quickly and wisely to spur the local economy and cut energy use."

President Obama today announced over $467 million from the American Reinvestment and Recovery Act to expand and accelerate the development, deployment, and use of geothermal and solar energy throughout the United States. The funding announced today represents a substantial down payment that will help the solar and geothermal industries overcome technical barriers, demonstrate new technologies, and provide support for clean energy jobs for years to come. Today's announcement supports the Obama Administration's strategy to increase American economic competiveness, while supporting jobs and moving toward a clean energy economy. "We have a choice. We can remain the world's leading importer of oil, or we can become the world's leading exporter of clean energy," said President Obama. "We can hand over the jobs of the future to our competitors, or we can confront what they have already recognized as the great opportunity of our time: the nation that leads the world in creating new sources of clean energy will be the nation that leads the 21st century global economy. That's the nation I want America to be."
