For all of solar power's positive attributes and benefits, the most obvious drawback it suffers from is its marriage to the sun; the sun must shine for the power system to work.

As the economy slumps, local site leads the way, helping local unemployed find green collar jobs.

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.

Coal plants are abundant in the United States. According to the Department of Energy they produce around 49% of the energy that we use.

Research by TU Delft proves that Dutch power stations are able to cope at any time in the future with variations in demand for electricity and supply of wind power, as long as use is made of up-to-date wind forecasts. PhD candidate Bart Ummels also demonstrates that there is no need for energy storage facilities. Ummels will receive his PhD on this topic on Thursday 26 February. Wind is variable and can only partially be predicted. The large-scale use of wind power in the electricity system is therefore tricky. PhD candidate Bart Ummels MSc. investigated the consequences of using a substantial amount of wind power within the Dutch electricity system. He used simulation models, such as those developed by Dutch transmission system operator TenneT, to pinpoint potential problems (and solutions).

In a new study, conducted by the Rock Mountain Institute, it has been found that electricity consumption can be reduced by 30 percent through energy efficiency and coal powered power generation can be reduced by 60 percent. vote nowBuzz up! The study, which spanned across 50 states, identified five states with highest electric productivity rates - New York, Alaska, Connecticut, Delaware and California - and stated that if all other states were to adopt similar efficiency parameters are implemented in other states the whole country can save up to 1.2 million gigawatt-hours annually. The study also brought out the long-term benefits of improving the electric productivity

Renewable Energy World has an article on the state of play in the ocean energy market - Harnessing the Tides: Marine Power Update 2009 One hundred and forty-one years ago, the relentless sea off Scotland's coast inspired the following observation from native son and author George MacDonald. "I climbed the heights above the village, and looked abroad over the Atlantic. What a waste of aimless tossing to and fro! Gray mist above, full of falling rain; gray, wrathful waters underneath, foaming and bursting as billow broke upon billow…they burst on the rocks at the end of it, and rushed in shattered spouts and clouds of spray far into the air over their heads. "Will the time ever come," I thought, when man shall be able to store up even this force for his own ends? Who can tell?"

TreeHugger has a post on the large volume of offshore wind power projects planned for Scotland - 6.4 Gigawatts of Offshore Wind Farms Slated for Scotland. A couple months back it was announced that the UK's Crown Estate would be helping out with financing pre-construction costs for offshore wind farms . Now comes word that The Crown Estate-which owns development rights in UK waters out to 200 miles-has offered exclusive agreements to nine companies for the development of offshore wind farms in Scottish waters totaling more than 6 GW of power. There are 10 plans on the table under these agreements: The largest is the Argyll Array at 1,500 MW, to be developed by Scottish Power Renewables. Airtricity Holdings has a sites amounting to 2,678 MW (Kintyre, 378 MW; Islay, 680 MW; Beatrice 920 MW; Bell Rock 700 MW). Inch Cape will see 905 MW of wind power developed by NPower Renewables. Fred Olsen Renewables will develop 415 MW at the Forth Array.

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.

HUD-DOE Agreement Will Help Spur a New Industry to Create Jobs for the Middle Class Philadelphia, PA - U.S. Department of Housing and Urban Development (HUD) Secretary Shaun Donovan and U.S. Department of Energy (DOE) Secretary Steven Chu today announced a major partnership between HUD and DOE that will streamline and better coordinate federal weatherization efforts to make it much easier for families to weatherize their homes and spur a new home energy efficiency industry that could create tens of thousands of jobs. Vice President Joe Biden, joined by Secretary Donovan and Secretary Chu, praised the announcement during his remarks at a meeting of the White House Task Force on Middle Class Families in Philadelphia.

Attic insulation can save you money these seasons

Twenty years ago NASA scientist, James Hansen told Congress that the use of fossil fuels was causing global warming. Earlier this year, Hansen and several co-authors published a paper titled Target Atmospheric CO2 that declared the amount of carbon reduction that needs to happen "if humanity wishes to preserve a planet similar to put to that on which civilization developed and to which life on Earth is adapted."
