What type of home heater system is best and most efficient?

American Electric Power (AEP) is doubling its goal of adding 1,000 megawatts (MW) of renewable energy to 2,000 MW by the end of 2011. This would bring the company's total renewable energy portfolio to more than 2,600 MW by the end of 2011. AEP has added 903 MW of wind generation since 2007, when the company committed to its original goal of adding 1,000 MW. AEP also set a new energy efficiency goal in 2009 to reduce consumption by 2.25 million megawatt-hours by the end of 2012. "Continuing to diversify our fuel mix with more renewable resources will allow us to meet our customers' energy needs and reduce our carbon footprint," said Michael Morris, AEP's chairman, president and CEO. "We can support development of a lower-carbon energy future through a combination of increasing renewable energy; driving the development of a new, interstate extra-high voltage transmission system to bring that renewable energy to market; promoting energy efficiency; and further developing advanced coal technologies such as carbon capture and storage."

Researchers at Ohio State University have accidentally discovered a new solar cell material capable of absorbing all of the sun's visible light energy. The material is comprised of a hybrid of plastics, molybdenum and titanium. The team discovered it not only fluoresces (as most solar cells do), but also phosphoresces. Electrons in a phosphorescent state remain at a place where they can be "siphoned off" as electricity over 7 million times longer than those generated in a fluorescent state. This combination of materials also utilizes the entire visible spectrum of light energy, translating into a theoretical potential of almost 100% efficiency. Commercial products are still years away, but this foundational work may well pave the way for a truly renewable form of clean, global energy.

A cheap new way to attach mirrors to silicon yields very efficient solar cells that don't cost much to manufacture. The technique could lead to solar panels that produce electricity for the average price of electricity in the United States.

The ORNL Energy Efficiency and Renewable Energy Program conducts research and development on energy-efficient technologies for transportation, industry, buildings, and power; and renewable energy production, storage, and utilization.

Officially grid-connected and set to work this week in Germany is a new wind tower from ATS. The novel tower construction allows very high hub heights that may increase a turbine's yield by 20% or more. With its hub height of 133 meters (436 feet), the system has an overall height of 180 meters (590 feet). "This is a great day for wind energy." said Frans Brughuis, Managing Director of the tower construction specialist Advanced Tower Systems (ATS). "Now the pilot project can demonstrate the high cost-effectiveness and efficiency of the ATS concept," The system, one of the largest wind energy systems with hybrid tower in the world, is installed at Germany's Windtest test field at Grevenbroich, near Cologne.

While the use of solar cells is become increasingly widespread, the silicon technology used in many types is becoming obsolete. JP Casey looks at concentrated solar power, micro-trackers and perovskite compounds as innovations that could potentially improve solar efficiency.

The solar panels are nowadays used for the residential purpose as the electricity bills are emerging a lot to bring the affordable power for the remote areas where there is no electricity...

A career as an energy auditor is becoming an increasingly important one as more and more people are looking to make their homes more energy-efficient.

An environmentalist-sponsored report claims that by 2050, the United States could sever ties with coal and nuclear power, draw nearly all its electricity from renewable sources and cut its greenhouse gas emissions by more than 80% -- all with existing technology and with a net gain of 14 million jobs to the domestic economy. The report, commissioned by Greenpeace and the European Renewable Energy Council and conducted by Germany's equivalent of NASA, was released this morning at a press briefing in Washington. It is heavy on charts and supporting data and transparent on some key assumptions. And its sponsors call its findings "conservative." At its core, the report envisions a steep drop in the United States' energy use, both in absolute terms and compared with International Energy Agency predictions -- driven by strict efficiency standards. It also projects dramatic changes in the nation's electricity mix, with wind and solar power mushrooming to replace coal, oil and nuclear sources that would gradually go offline.

As traditional energy sources become increasingly rare and expensive, many homeowners are turning to the skies and learning how to harness energy from the sun. Solar cell technology has been around since the 1950s, but technology has improved considerably and at current levels of efficiency it is worth taking the time and effort to consider a Solar Power Home Now Solar cells are also called photovoltaics, or PV, by the boffins. In basic terms, they are made of semi conducing materials, which, when exposed to the sun go through a distinct process. The solar energy separates the electrons from the atoms within the material and the movement of the electrons creates power, or electricity. Thus light (photons) is converted into electricity (voltage).

Grist has a post on new ideas for improving wind power technology, pointing to a Tyler Hamilton "Clean Break" column in the Toronto Star - Wind turbines get fancy. Solar energy sucks up a lot of research attention, partly because solar energy systems still have so much room for improvement. Wind turbines, on the other hand, have been around for over 1,000 years, and although the modern versions are vastly larger and more efficient than their ancient counterparts, the basic concept hasn't changed much. But the standard blades-on-a-horizontal-axle version of wind energy systems (as opposed to more exotic flavors like kites or blimps) may yet be poised for some big leaps forward, several of which were profiled in a recent Clean Break column.

By office office office office office building green-and retrofitting existent buildings-the countries of North America could cut hothouse gas emissions by some-more than twenty-five percent North American homes, offices as good as alternative buildings minister an estimated 2. 2 billion tons of CO dioxide to a ambience each year-more than a single third of a continent's hothouse gas wickedness outlay. Simply constructing some-more energy-efficient buildings-and upgrading a insulation as good as windows in a existent ones-could save a whopping 1. 7 billion tons annually, says a brand brand new inform from a Montreal-based Commission for Environmental Cooperation( CEC), an general classification determined by Canada, Mexico as good as a U.

China will put 60,000 new-energy vehicles-including fuel-cell vehicles, hybrid-electric vehicles, and battery-electric vehicles-into trials in 11 cities over the next few years to support the development of a fuel-efficient, alternative-energy auto industry, according to a report in sina.com.
