In a significant milestone in the deployment of flexible, printed photovoltaics, Konarka, a solar-cell startup based in Lowell, MA, has opened a commercial-scale factory, with the capacity to produce enough organic solar cells every year to generate one gigawatt of electricity, the equivalent of a large nuclear reactor. Organic solar cells could cut the cost of solar power by making use of inexpensive organic polymers rather than the expensive crystalline silicon used in most solar cells. What's more, the polymers can be processed using low-cost equipment such as ink-jet printers or coating equipment employed to make photographic film, which reduces both capital and manufacturing costs compared with conventional solar-cell manufacturing.

Siemens Building Technologies is sponsoring a Virtual Trade Show on December 10th and 11th from 8:00am - 6:00pm CST. This Virtual Energy Forum is a two day online-only event focused on how leading companies can adopt better energy management practices to cut costs, while at the same time adopting clean energy alternatives -- presenting alternative energy technologies, policies, and best practices in a live, interactive environment. The event is designed to meet the needs of corporate energy executives in a way that is not possible with physical events, webinars or other means.

Shortened workweeks, flextime, enforced time off; none of these are new concepts in today's workplace. But some U.S. state governments and organizations are turning to four-day workweeks and alternative work schedules as a way to combat the recession as well as cutting down on energy consumption. They're having varying degrees of success.

This Valentine's Day instead of buying fresh cut flowers that only last a few days and are totally full of pesticide toxins - Make your sweetie flowers that are eco-friendly because they are made from some extra scrap fabric and will last for years. Here is a great how-to guide by Becky Striepe over at ...

"The world's southernmost wind farm, in Antarctica, is now operational. The Ross Island wind farm will supply about 11 percent of the power to New Zealand's Scott Base and the American McMurdo Station. Previously, the two sites relied on diesel-powered generators for electricity. The wind farm will cut diesel consumption by about 463,000 liters a year and reduce carbon dioxide output by 1,370 tons annually, according to New Zealand-based Meridian Energy, the project's developer. The three turbines, each 37 meters tall and 33 meters wide, are generating 330 kilowatts of power."

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."

U.S. Department of Energy (DOE) Secretary Steven Chu today announced selection of 53 new wind energy projects for up to $8.5 million in total DOE funding. These projects will help begin to address market and deployment challenges identified in DOE's 2008 report: "20% Wind Energy by 2030." Increasing wind energy generation will be a critical factor in achieving the Obama Administration's goals for clean energy, while also supporting new green jobs. Secretary Chu made the announcement by video at the WindPower 2009 Conference in Chicago this week. "Wind energy is one of our most promising renewable energy sources," said Secretary Chu. That's why I'm pleased to make this announcement today. By continuing to make investments in renewable energy we can cut our dependence on foreign oil and invest in a clean energy agenda that creates jobs and puts money back into the pockets of consumers."

I've got another guest post from Neil Howes up at TOD, this one proposing a rough plan for North AMerica to obtain 50% of its power from wind by 2030 - A North American Wind Energy Scenario. Would a "50% of electricity generated by wind scenario" work in North America by 2030? In this post, I make a rough cut estimate of what might be required to make such a transition in about 20 years time. Most proposals that are being made rely on a very big increase in carbon free energy, both to charge electric vehicles (EV's) and to replace oil and natural gas (NG) presently used for hot water and space heating. In this post, I lay out a path by which 50% of North American energy might come from wind by 2030, including replacement of a large share of oil and natural gas use by electricity. ... High quality wind resources (wind speeds greater than 6.9m/sec) in the US are estimated to be >5,500GWa, about x10 all of N America's present electricity production of 550GWa. Canada's potential appears to be similar or greater than the US, while Mexico's wind resources are more limited (these figures do not include deep offshore resources that could be harnessed by floating wind turbines or higher altitude wind resources that could potentially be harnessed by airborne wind turbines).

The number of wind turbines is set to quadruple over the next decade under government plans to force through wind farm planning applications. Ministers have put wind power at the heart of a Renewable Energy Strategy, which is due to be released on Wednesday. It will outline how Britain is to meet its target of a 34 per cent cut in CO2 emissions by 2020.

This electric chain saw is very effective for use as it runs on tool less chain tension system. It can be used for cutting any part of your furniture. You can use it with quite ease as it is quite comfortable to grip the system.
