California has topped the American Council for an Energy Efficiency Economy (ACEEE)’s state energy efficiency ranking for a fourth year in a row. The State Energy Efficiency Scorecard ranks each region on its energy efficiency policies, programmes, transport policy, building performance codes, combined heat and power and appliance standards.

The city may enter a three-year contract aimed at saving the city an estimated $3 million on electric power acquisition and distribution over 12 years for $1.8 million over three years. The proposed agreement would be made with non-profit American Municipal Power Inc. (AMP) to operate an energy efficiency program called Efficiency Smart Power Plant. Cuyahoga Falls has its own municipal electric system and purchases power through AMP.

According to a new study of food waste in the U.S., it takes the equivalent of 1.4 billion barrels of oil to produce get a year’s worth of food to the market, but about 350 million barrels of that goes down the drain in the form of wasted food. The study, reported by The American Chemical Society, is noteworthy not only for what it includes about food-related energy, but also for what it leaves out.

In honor of Blog Action Day on the topic of water, here is a bit of good news about a new low-cost, energy efficient method for purifying drinking water without the use of chlorine. Scientists at Stanford University have developed a new kind of water filter that uses a combination of silver, cotton, and electricity to kill up to 98 percent of E. coli bacteria in contaminated water. The system was recently described in the American Chemical Society journal.

One of the first 100 percent electric mass-production cars in US is to be launched this year and will be for sale starting 2011. The CODA Sedan will be manufactured by a private American firm that sells battery systems and all-electric vehicles.

U.S. Energy Secretary Steven Chu announced the release of a new proposed energy efficiency standard for residential refrigerators, refrigerator-freezers, and freezers. The standard, as proposed, could save consumers as much as $18.6 billion over thirty years. The Obama Administration has made efficiency standards a major priority as a way to save energy and money for American families and businesses.

Previous news were saying that the Obama administration doesn’t have any plans of installing solar panels on the White House. Not even a month has passed, and a representative of the White House in Washington, DC says solar panels will be installed on the White House in order to impulse Americans to adopt green energy.

With a stalled Green energy movement that seems to have convinced few people that it can actually replace our dependence on fossil fuels, Tom Rand thinks it's time to move the goal posts. An engineer who is also a venture capitalist who puts his money where his mouth is, his challenge is simple: America can either pioneer green energy as an investment that will pay off for centuries to come, or wind up paying someone else for the same solutions down the road.

A team of Ukranian and American scientists have discovered that by using structures called ferroelectric nanowires, they can generate electricity from a temperature difference. This concept is now new, but rather uses different approaches and materials. It can harvest energy by using the temperature difference between materials and/or ambients.

Being gifted with many active volcanoes, Central America wants to tap them for producing green energy which will cut its dependence on oil imports and also help reduce the CO2 emissions. Because the region is placed above shifting tectonic plates in the Pacific basin, it has great potential for geothermal power produced by heat stored deep in the Earth’s crust.

A new study reported in the journal Applied Physics Letters in August this year (published by the American Institute of Physics), explains how solar energy could potentially be collected by using oxide materials that have the element selenium. A team at the Lawrence Berkeley National Laboratory in Berkeley, California, embedded selenium in zinc oxide, a relatively affordable material that could make more efficient use of the sun’s power.

This technique has an enormous potential. Only in the United States, for instance, the total surface of roads, highways and open parking lots is estimated in over 100,000 square kilometres. The proposal comes from an American company which, using funds granted by the US Federal Highway Administration, is designing resistant photovoltaic panels on which cars can drive, with tiny prisms built into the surface in order for tyres to grip.

In order to manufacture high quality products which have both domestic and international competitiveness, Catalan JSC has invested in the most modern technological lines and equipment using Robots and automation technologies. In addition, some auxiliary equipment is also imported from countries such as Japan, Britain, America and Belgium. Although the company is growing rapidly and creating a foothold in the market, the actual energy consumption is still high with over VND90 billion per year, including costs for electricity, coal and gas.

Department of Economic and Community Development Commissioner Matt Kisber today announced the State Energy Efficient Appliance Rebate Program (SEEARP) will open Tuesday, Aug. 24 at noon CDT. Rebates will be available on a first-come, first-served basis for qualifying Energy Star heating and cooling appliances, funded out of $5.9 million in American Recovery and Reinvestment Act dollars.

The left side of the chart shows the different sources of energy and the amounts produced. Following the flow of energy from left to right, the pink boxes show where the energy is consumed (electrical generation, residential, commercial, industrial and transportation) while the shades of gray show the amount of energy lost or rejected – often through heat loss.

A group of engineers at Bridgestone America’s Technical Center in Akron, along with students from DeLaSalle School in Kansas City have recently developed a new all-electric car which has been successfully tested on Bridgestone’s Texas Proving Grounds.

Trong xã hội hiện nay, xe chạy điện đang đối diện với những thách thức từ những chiếc xe dùng xăng gây ô nhiễm môi trường. Luôn bị coi là quá đắt so với thu nhập trung bình của người tiêu dùng, giới hạn về quãng đường đi và sự bất ổn trong điều kiện thời tiết khắc nghiệt, chưa kể đến việc phải xạc điện liên tục, đó chính xác là những gì mà các công ty dầu lớn muốn vẽ nên về xe chạy điện.

American Electric Power CEO Michael Morris is all too familiar with the challenges of incorporating renewable energy into the existing industrial framework. But he believes that the largest of these hurdles can be overcome with sound planning for the future. Here’s what he has to say.

The Southeast False Creek Neighborhood Energy Utility, or N.E.U., supplies space heating and domestic hot water to local buildings using heat recovered from wastewater and raw sewage. “This is a test case for Vancouver,” said Chris Baber, the N.E.U.’s manager. It is also the first “district” energy system in North America to draw heat from untreated wastewater. There are only three similar projects worldwide: two in Oslo and one in Tokyo.

Spanish wind turbine builder Gamesa and San Diego wind farm developer Cannon Power Group have teamed up to start building a wind farm South of the Border to supply clean power to a quarter of a million households in both California and Mexico from 500 MW of power by 2015. Cannon says the site’s potential capacity is ultimately 1,000 MW.
