Tập đoàn năng lượng MidAmerican của tỉ phú Warren Buffett đã đồng ý mua một cánh đồng quang năng Topaz (California, Mỹ) trị giá 2 tỷ USD.

The Inter-American Development Bank (IDB) and the Global Environment Facility have contributed $1.5m in grants for solar lighting that has cut crime at two earthquake settlement camps in Haiti.

Enel Green Power North America announces the development of the world's first solar geothermal hybrid power plant in Nevada (USA)

This evolution is on display at the American Wind Power Center in Lubbock, which bills itself as the world’s largest windmill museum.

Glassmaking in America has been in decline for at least a decade as manufacturers have moved production to China and other emerging economies. But can the green-buildings movement spark a revival?

Despite widespread rumors in North America that Germany was abandoning its system of Advanced Renewable Tariffs, the country's upper chamber of parliament, the Bundesrat, approved the latest revision of its pioneering Renewable Energy Sources Act on July 8.

As of 2010, 57% of electricity in Latin America and the Caribbean stems from hydro sources while another 40% comes from thermoelectric power plants using fossil fuels and natural gas. Of the remainder, 2% comes from nuclear stations and 1% from wind, solar and geothermal plants.

More evidence that clear, strong policies are key to renewable energy development came recently via the American Wind Energy Association (AWEA). In a statement issued by the association, some statistics about wind energy growth in the country and the states that lead in wind energy development indicate that areas with strong policy are driving development at an impressive pace.

In a sunny corner of Italy that produces roses and olive oil, an American startup will get to demonstrate its technology to harvest both electricity and heat. Solergy, which is in the process of raising a B round of funding, plans to install a hybrid solar electric and thermal system on top of a greenhouse for the farm Azienda Agricola Ciccolella in the Puglia region, and intends to team up with Ciccolella to market Solergy’s systems to growers in the area, said Yoav Banin, Solergy’s CEO.

“Algae has been a hot topic of biofuel discussions recently, but no one has taken such a detailed look at how much America could make – and how much water and land it would require — until now,” said Mark Wigmosta, lead author and a PNNL hydrologist. “This research provides the groundwork and initial estimates needed to better inform renewable energy decisions.”

America is yearning for leadership, and energy policy is another area where it is lacking. Democrats argue we must do more to promote and develop alternative fuels. Republicans counter that there is no alternative to oil and gas in the short term and that we need to increase our domestic output to secure our energy supply.

American consumers don’t want things forced on them by the government, but they are slowly starting to become aware of energy issues via the rising cost of energy and the geo-political climate, said Crane. “Everyone in this room has a vested interest in electric vehicles becoming successful,” said Crane to the room largely made up by investors, and the future is “all about electric vehicles.”

Advocates of coal power argue that it is among the cheapest sources of energy in the United States and allows for lower-cost power. But a new Harvard study found that whatever money is saved in operation costs is completely negated by the cost coal plants inadvertently pass on to the American public: $345 billion.

Clearing up the regulatory hurdles that are slowing development of electricity transmission lines would provide a significant boost to U.S. wind power development, industry officials said Wednesday. The American Wind Energy Association is holding a two-day workshop in Omaha focused on the challenges of transmitting power to places that need it. The biggest regulatory barriers have to do with who pays for high-voltage transmission lines and who decides where the lines will go.

Các nhà giao dịch và đầu tư đánh giá tương đối tích cực các tín hiệu kinh tế Mỹ, đồng thời tin tưởng tăng trưởng sẽ tiếp tục trong năm 2011. Phiên hôm qua, chỉ số Dow Jones mất điểm, chủ yếu do cổ phiếu của American Express sụt mạnh. Tuần trước, cổ phiếu của Visa và MasterCard cũng đi xuống sau khi FED đề xuất giới hạn phí giao dịch thẻ debit. Nhưng phải sang đến đầu tuần này, các nhà đầu tư mới bắt đầu lo ngại về trường hợp của American Express.

A day after Energy Secretary Steven Chu's "Sputnik speech," in which he warned that China was investing billions in renewable energy while American politicians bickered over small-potatoes stimulus spending on green technology, a report from Ernst & Young released Tuesday confirmed Asia's ascendancy.

Today Osram Sylvania, a North American lighting manufacturer, announced that it will be commercially producing an LED light bulb designed to replace a 60-watt incandescent bulb. Millions of 60-watt incandescent bulbs are currently sold each year, but according to the Energy Independence and Security Act of 2007, these light bulbs must be phased out by 2014.

Paul Montgomery, một sinh viên cao học đại học Pennsylvania đang thiết kế một loại bếp nấu ăn phục vụ người dân những nước đang phát triển. Trong hội thảo sắp tới của Hội nghị thiết kế Pan-American/Iberian lần 2 tổ chức tại Cancun, Mexico, Paul Montgomery sẽ cho ra mắt phát minh mới của mình là chiếc quạt chạy bằng nhiệt giúp bếp hoạt động hiệu quả hơn, đồng thời đẩy lùi những nguy hại cho sức khỏe gây ra do những căn bếp kín.

Now that would be a brutal blow for any industry battered by a vicious recession. But it's particularly bad news for the American wind industry, which had defied the downturn by installing a record 10,000 megawatts of new capacity in 2009. New wind capacity had grown an average 39 percent annually over the previous five years and represented 39 percent of all new electrical generation that came online last year.

Arizona is one of the four most improved states in terms of energy efficiency, according to a study released today by the American Council for an Energy – Efficient Economy. The state ranked 18th, up 11 spots from 2009, tying Utah for the most movement. Close behind were New Mexico and Alaska, which both leaped eight spots.
