The two reports on the impacts of EE/RE on Texas -- Role of Energy Efficiency and Onsite Renewables in Meeting Energy and Environmental Needs in the Dallas/Fort Worth and Houston/Galveston Metro Areas and The Economic Benefits of an Energy Efficiency and Onsite Renewable Energy Strategy to Meet Growing Electricity Needs in Texas -- were released today by the American Council for an Energy-Efficiency Economy (ACEEE). These studies build upon an ACEEE report released last March that examined the statewide impacts of a suite of EE/RE policies that showed Texas could meet most of its projected needs for electricity while also addressing concerns about peak demand.

In October 2006, Google announced a commitment to solar energy production and launched the largest solar panel installation to date on a corporate campus in the United States. Google has installed over 90% of the 9,212 solar panels that comprise the 1,600 kilowatt project. Panels cover the rooftops of eight buildings and two newly constructed solar carports at the Googleplex (check out this fly-over video).

Demand for renewable energy is outstripping supply, pushing up prices and raising the specter that some states may not meet clean-energy mandates.

Solar proponents love to boast that just a few hundred square kilometers' worth of photovoltaic solar panels installed in Southwestern deserts could power the United States. Their schemes come with a caveat, of course: without backup power plants or expensive investments in giant batteries, flywheels, or other energy-storage systems, this solar-power supply would fluctuate wildly with each passing cloud (not to mention with the sun's daily rise and fall and seasonal ebbs and flows). Solar-power startup > Ausra > , based in Palo Alto, thinks it has the solution: solar-thermal-power plants that turn sunlight into steam and efficiently store heat for cloudy days. >

Power generation from low-carbon energy sources like wind, solar and nuclear should soon become competitive with electricity generated by coal, the cheapest of fossil fuels, the chief executive of FPL Group Inc. (FPL.N: Quote, Profile, Research) said on Wednesday.

Yesterday, the European Parliament approved by overwhelming majority the "Thomsen Report" on the Roadmap for Renewable Energies in Europe. Crucial for the future of solar thermal: the call for the adoption in all Member States of renewable heat obligations, at least in new buildings and those undergoing major renovation.

In a speech this week, New Zealand Prime Minister Helen Clarke announced New Zealand's intention to commit to 90% renewable electricity by 2025, according to a press release issued by the New Zealand government. The country already uses 70% renewable electricity, primarily hydro- and geothermal power and will continue to increase its use of renewables over the next 20 years. 

Companies that have switched to renewable energy are reporting a number of bottom line advantages, including reduced corporate greenhouse gas emissions, diversification of energy sources to hedge against fluctuating fossil fuel prices, as well as strengthening customer relationships and brand differentiation.

China is proposing an international multilateral science and technology cooperation scheme to hasten development of clean renewable energies.

Renewable energy in the United States is on the rise. America now generates twice as much electricity from the wind and the sun as we did just four years ago, and 2007 promises to be another year of record growth.

The British government plans to build a wave farm off the Cornish coast that could supply electricity for 7,500 homes.

a number of the renewable energy-rich areas are too far from the electric transmission grid to render them useful. "We've made tremendous progress developing the transmission plan to bring electricity from the wind-rich Tehachapi Mountain area to Southern California customers. Our goal with RETI is to identify the next Tehachapi." -- Dian M. Grueneich, Commissioner, California Public Utilities Commission In an attempt to alleviate this dilemma, California has formed a public-private partnership called the Renewable Energy Transmission Initiative (RETI) to consider the feasibility of building new transmission lines to access renewable generation.

Renewable energies and demand-side technologies have become the third largest investment class for venture capitalists (VC) in the U.S.

KEMA, in partnership with the civil engineering firm Bureau Lievense and technology illustrators Rudolph and Robert Das, has developed an "Energy Island" concept to store power generated from an offshore wind farm. The concept design is the initial result of an on-going feasibility study being conducted for Dutch energy companies.
