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.

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.

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 Such high energy consumption is attributed to the use of outdated technologies and equipment as well as insulated steel furnaces.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.

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
