Leave it to larger-than-life Texas to lead the U.S. into a new energy future. While the state is most closely associated with oil, it has also been an early pioneer of wind power, and is beginning to embrace solar energy along with armloads of new green jobs. Now the San Antonio Water System has set the national bar high in the sewage-to-biogas field, by becoming the first water district to hook a biogas facility up to a commercial gas pipeline.

At three feet (11 meters) tall, the SunCatcher is almost four times bigger than the world’s largest biological flower, the Sumatran titan arum. It has parabolic petals that appear virtually flat, like those of a buttercup. The device is made up of 40 mirrors, tightly arranged into a 3,400-square-foot (315-square-meter) dish that, like a real flower, angles toward the sun.

Thien Thanh company is a private enterprise (Phung Xa, My Duc, Ha Noi) with the main products of textile, dye and exported towel; annual energy cost is over VND 4 billion. Engaging in energy audit program, this business has found out eight solutions to use energy and coal effectively.

There are more than two billion people worldwide with no access to drinking water. This is the reason why researchers over the globe are trying to find solutions such as desalination. This reverse osmosis of water is the most efficient and economical form of desalination but the problem is that it needs 3 kWh per cubic meter of water. Solar panels and wind turbines can be used to supply this power.

A Chevrolet Volt electric vehicle seen here October 7 charging at a solar-powered charging station in Detroit, Michigan. More than 5,300 charging stations will be installed in Michigan as the birthplace of the US auto industry prepares for the introduction of electric cars.

South Yorkshire is the greenest part of Yorkshire, according to The Energy Saving Trust. The Trust says that since April people in South Yorkshire have installed more renewable energy systems than the rest of the region put together. There are now a total of 426 installations in the county - most of them in Sheffield, followed by Rotherham, Barnsley, and then Doncaster. That compares with 199 installations in West Yorkshire, 78 in North Yorkshire and 40 in the Humber.

In Chau Khe, Dinh Bang (Bac Ninh Province), more than 800 households are involved in iron and steel production. To temper and laminate steel, they consume about 200 million kWh of electricity and 30,000 tonnes of coal, and total expenditure on energy consumption amounts to VND150 billion each year. Such high energy consumption is attributed to the use of outdated technologies and equipment as well as insulated steel furnaces. At some stages of steel production, the rate of energy losses is 20-25 percent.

A long list of sustainability measures saved School District 43 more than $1.2 million in the past year. But the district will soon need to fork over extra cash for carbon offsets, since the provincial government requires the public sector be carbon neutral by the end of 2010.

Với lợi ích to lớn góp phần tiết kiệm tài nguyên, đặc biệt là đất nông nghiệp, giảm thiểu khí phát thải gây ô nhiễm môi trường, giảm chi phí xử lý phế thải của các ngành công nghiệp, tiết kiệm nhiên liệu than, đem lại hiệu quả kinh tế chung cho toàn xã hội, vật liệu xây không nung đã được phát triển ở nhiều nước trên thế giới từ lâu.

Lockheed Martin and Rice University scientists have recently discovered how to use the all-abundant silicon to make battery electrodes that could hold up to 10 times more lithium and enhance the battery’s overall capacity from 300 mAh/gram to more than 3,000 mAh/gram. This could lead to an unprecedented rise in storage capacities for electric car batteries, in a crucial moment for their development.

Florian Bailly, a French cyclist, completed a 12 countries and two continents tour on a custom-made solar bike this week. The 10,000-kilometer journey, from France to Tokyo, lasted two-thirds less than it would have taken on a normal bike.

A new discovery at Rutgers University looks likely to lead to the creation of efficient and inexpensive solar cells made of plastic. The researchers discovered that excitons - energy-carrying particles generated by packets of -can travel on the order of a thousand times farther in organic semiconductors than previously thought.

Về mặt lí thuyết, quá trình sản xuất khá đơn giản; sau khi tách 2 thành phần của hợp chất methan là hydrogen và cacbon, hydrogen sẽ được nén lại cho đến khi đạt 99,9% độ tinh khiết. Loại hydrogen này sẽ cung cấp năng lượng cho 2 ô tô và 2 xe buýt chạy bằng nhiên liệu hydrogen. Nhà máy cũng sẽ tạo ra khoảng 320KW điện để cung cấp điện và nước nóng đến Nanji Art Studio trên đảo Nanjido

Những nguồn năng lượng truyền thống như thủy điện, dầu mỏ, than… đều đang đứng trước những cảnh báo cạn kiệt buộc nhân loại phải vào cuộc tìm kiếm nguồn năng lượng thay thế. Không chỉ trên thế giới, tại Việt Nam vấn đề này cũng đã được đặt ra từ lâu và một số nguồn năng lượng giải pháp đã được các nhà khoa học nước ta nghiên cứu, thử nghiệm và đưa vào ứng dụng thành công.

It’s known from high school that aluminum can split water in hydrogen and oxygen, with aluminum hydroxide as byproduct. A team of Purdue University researchers has developed a mechanism that uses this reaction between aluminum, water and a liquid alloy to extract hydrogen directly from seawater and use it in boats and ships.

Các giải pháp tiết kiệm chi phí năng lượng bao gồm giải pháp với hệ thống lò hơi, hệ thống máy cán, hệ thống chiếu sáng. Tổng hợp các phương án đề ra ước tính mỗi năm công ty CP Cao su Hà Nội có thể tiết kiệm trên 470 tấn than và khoảng 1 triệu Kwh điện năng. Tính theo mức giá đang áp dụng, mỗi năm doanh nghiệp sẽ giảm chi phí trên 2,1 tỷ đồng.

United States’ Environment Protection Agency (EPA) has increased the percentage of ethanol blending optional for cars and light-weight trucks made in or after 2007 to 15 percent (E15). This is the first increment in the ethanol blending standard in more than 30 years. Since 1979, automobiles had an option to use only 10 percent blended ethanol (E10) in gasoline.

More than 300 students in HCM City on Sunday took part in activities for the International 350 Day for Climate Change. Together with millions of people around the globe, they raised their voices about climate change and environment protection. The students made a painting of five-by-five metres, and 260 small paintings that were combined to depict the number 1,000 in celebration of Ha Noi’s millenium anniversary.

According to architect Pham Minh Hieu of Song Da Thang Long Joint Stock Company, the design of window for any architectural space needs to focus on the air convection. The sizes of window can be various, depending on the structure of the house and hobbies of the owner.

Tocco is a remarkable Italian town, not only for its ancient heritage, but also for its futuristic projects that concern the implementation of renewable energy installations. The town benefits four wind turbines that are more than enough to meet the needs of its 2,700 inhabitants.
