A new bill submitted by Rep Henry Waxman (D-CA) and Edward Markey (D-MA), the American Clean Energy and Security Act, would aim to reduce emissions of carbon dioxide and other greenhouse gases by 20% from 2005 levels by 2020 (vs. the 15% proposed by President Obama), and by 80% by 2050.

Cyberspies have penetrated the U.S. electrical grid and left behind software programs that could be used to disrupt the system, according to current and former national-security officials.

Hydro energy’s potential may be overlooked because; it is “old” renewable energy, or because like nuclear energy, some hydro electric schemes have been criticized by environmental groups, but most importantly a perception by many, that most hydro electric potential in North America has already been exploited. Hydro electricity deserves more scrutiny because; 1) North America has significant undeveloped potential, 2) the technology is well understood, although technical improvements continue to be made, especially for low head and small hydro, 3) hydro has a very high energy return on energy investment (ERoEI), 4) additional hydro can enable more wind and solar energy capacity to be absorbed by the grid, 5) hydro potential is more geographically dispersed than wind and solar, and finally, 6) the cost of developing additional hydro capacity is moderately low and has very low technical and financial risk.

The Department of Interior (DOI) released a report concluding that shallow water wind energy alone could provide at least 20% of the electricity needs of almost all coastal states.

In 2007 the cumulative market share of direct drive turbines was around 14%, a percentage that has varied little (between about 13%-15%) during past few years.

First Solar, Inc. (Nasdaq: FSLR) today announced it reduced its manufacturing cost for solar modules in the fourth quarter to 98 cents per watt, breaking the $1 per watt price barrier.

The US and Canada have agreed to work together on energy technologies from smart grids to carbon capture and storage (CCS).

The Energy Council of Thursday 19th February focused on the second Strategic Energy Review. Inevitably, the Council was cautious agreeing concrete changes to existing rules or arrangements on the basis of the Strategic Energy Review. Instead it has cautiously welcomed many of the proposals tabled or announced in the Review, awaiting the detailed Commission proposals or the outcome of discussions in Council on the specific proposals. Nonetheless, the conclusions do demonstrate a willingness of the member States for some - probably gradual - change in developing a more Community approach to energy security issues.

The International Thermoelectric Society website reported that Volkswagen showed a prototype vehicle equipped with a thermoelectric generator, recovering the dissipated heat energy and converting it into electricity. The prototype has been shown at the “Thermoelektrik - Eine Chance Für Die Atomobillindustrie?” meeting held in Berlin in October 2008.

Project Energy Code focuses on understanding the “green gap”—the individual statements of concern over energy and the environment and the actual decisions and behaviors of individuals with the ability to modify electricity consumption, and the institutions that enable options mentioned above. These Project Energy Code differences between respect to their energy choices. Why does this green gap exist in our electricity consumption choices?

Our lack of knowledge about our own energy usage is a huge problem, but also a huge opportunity for us all to save money and fight global warming by reducing our power usage. Studies show that access to your household's personal energy information is likely to save you between 5–15% on your monthly bill, and the potential impact of large numbers of people achieving similar efficiencies is even more exciting. For every six households that save 10% on electricity, for instance, we reduce carbon emissions as much as taking one conventional car off the road (see sources and calculation).

The RMI study, "Assessing the Electric Productivity Gap and the U.S. Efficiency Opportunity," determines the productivity rate of each state by measuring how much gross domestic product is generated for each kilowatt-hour consumed.

The first of 200 micro-CHP boilers was today put into service in the Apeldoorn suburb of Woudhuis as part of a large-scale field trial. Annelies van der Kolk, member of the Gelderland provincial executive responsible for climate and environment, today set the trial period officially in motion. "I am proud of this result of innovation and cooperation by so many parties. It's one of the ways we are working together towards a sustainable Gelderland", says Annelies van der Kolk.

The European Parliament has overwhelmingly backed a comprehensive energy plan for the region, including a 35% improvement in energy efficiency.A large majority of MEPs voted to endorse the EU’s Second Strategic Energy Review, which was proposed by the EC in November last year.The proposals form the basis of Europe’s ’20-20-20’ policy which aims to cut CO2 and energy use by 20% by 2020, and increase renewables by 20%.

The Liverpool John Lennon Airport, in Liverpool, U.K., will soon become the world's first to try a revolutionary piece of technology that will recycle the breath of passengers into biofuel.

This paper will provide recommendations/ideas for obtaining a highly efficient gearbox while still taking into consideration application constraints.

According to Mr. Umbach, the development of fully operational Smart Metering solutions across Europe is essential in achieving the EU 20-20-20 targets

Wind accounted for 35% of all new capacity additions in the US and 40% of new capacity in Europe in 2007. Wind generating capacity in China grew by 127% in 2007 compared to 2006.

A new survey of consumers' views on Europe's energy label for domestic appliances has confirmed a clear preference for the existing A to G scheme. The findings were published by the UK government's market transformation programme last week.

A brief general picture of the world, european and italian energy situations is made, analyzing several different energy sources and paying attention to the relations energy-quality of life, energy-environment and energy-health. Then will be discussed fossil fuels, renewable energies, the role of electric energy, nuclear energy, energy savings, the greenhouse effect, a possible sustainable development, the hydrogen economy and the risk and its perception. Then follow the conclusions and perspectives.
