Discovery cho biết, chiếc bánh xe là phát minh của một nhóm sinh viên tại Viện Công nghệ Massachusetts, Mỹ. Họ đặt tên nó là Copenhagen Wheel (bánh xe Copenhagen) vì Copenhagen, thủ đô của Đan Mạch, là thành phố mà xe đạp là phương tiện giao thông phổ biến.

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.

Nhà máy Beleluane đặt tại tỉnh Maputo đã được khởi công. Nơi đây sẽ sản xuất thiết bị của tấm thu năng lượng mặt trời. Vốn đầu tư ban đầu cho nhà máy này ước tính vào khoảng 10 triệu USD.

A new joint venture research work at Stanford and SLAC National Accelerator Laboratory, supported by Department of Energy and DARPA has come up with a new solar energy conversion process that can potentially double the efficiency of solar cells. Stanford engineers have discovered this new and totally different process to harvest energy from sun.

Trong nỗ lực nhằm tận dụng tối đa các nguồn năng lượng thay thế như sức gió, năng lượng Mặt Trời, địa nhiệt và nhiên liệu sinh học, Australia đã lên kế hoạch xây dựng nhà máy sản xuất điện bằng sức gió (nhà máy phong điện) lớn nhất Nam bán cầu vào năm 2013.

Toàn bộ cấu trúc của AK1000 sẽ được đưa ra ngoài khơi cách bờ 12 dặm rồi dìm xuống lòng biển. Theo Gizmag thì hãng Atlantis đã chi hết 25 triệu USD để thực hiện nguyên mẫu AK1000 và đưa nó vào hoạt động. Hãng Reuters cho biết Chính phủ Scotland lên kế hoạch khai thác năng lượng đại dương để cung cấp điện cho 0,5 triệu hộ gia đình vào năm 2020.

Before joining the cleaner production component in the industry (CPI), during the production process, Ngoc Lap tea factory used to encounter major environmental problems such as high concentration of dust, noise pollution, and smoke from burning coal, which directly affected the working conditions of employees, worsen living condition in the neighborhoods and schools near the factory. The amount of carbon dioxide emission from the plant is about 2,500 tons per year.

Two co-authors Nguyen Trong Kien and Nguyen Van Hoang of Nguyen Hoang Tuy Company (Ho Chi Minh City) have successfully implemented a system for remote control and supervision of public lighting, detection of electrical leak system via SMS. Accordingly, in addition to remote controlling lighting of public lamps, the system is also capable of detecting current leakage status and reporting to the management department for prompt react.

Ocean Renewable Power Company (ORPC), an industry leader in tidal, river and deep-water ocean current energy technology and projects, announced today that its Beta Power System, the largest ocean energy "power plant" ever installed in U.S. waters, has successfully generated grid-compatible power from tidal currents at its Cobscook Bay site in Eastport, Maine.

One of the largest orchards in Massachusetts has just cut its utility bill 80% with a $1.1 million 220 KW solar power plant. The state of Massachusetts helped Carlson Orchards with grants totaling $595,000 to help in the installation of the 1,050 solar photovoltaic panels.

One purpose of developing solar power technology is to support the load for the national grid and enable consumers to use EVN’s electricity at peak hours with price of off-peak hours (price of grid electricity at night is only 500 dong per Kwh, while during peak hour it is about 2000 dong, calculated accumulatively).

Who would have imagined that teabags can be used for purposes other than those of packaging tea leaves, and filtering their flavors? No one else except South Africa’s Stellenbosch University scientists led by Eugene Cloete, who invented a kind of teabag which, instead of filtering tea impurities, purifies water at the lowest price and energy consumption possible.

Khi nói đến xe chạy điện, bạn thường nghĩ đến 2 thuật ngữ: sự tự động hóa và kết cấu xạc điện. Hai thuật ngữ này biến đổi ngược chiều nhau, sự tự động hóa càng cao đồng nghĩa với cần ít thiết bị hơn và được thị trường chấp nhận nhanh hơn.

Cassava is widely known as a popular food used for breeding activity and in some other food processing industries. Few people, however, know that cassava is now the main material for producing the E5 bio-gasoline. While preparing for the market introduction of E5 bio-gasoline, Petrol Viet Nam Corporation and PV OIL have already set up a plan to plant cassava to use as raw material for production of clean gasoline.

According to the researchers at Edinburgh Napier University, whisky is being used to develop a new biofuel, which could power cars and even airplanes in a few years. They found a new way to produce biofuel from two main byproducts of the whisky distilling process: “draff”, the spent grains and “pot ale”, the liquid from the copper stills.

When you think of electric cars, you generally mean two terms in which they exist: autonomy vs charging infrastructure. These two words compete with each other to a certain point, because higher autonomy means less infrastructure needed, hence faster adoption by the market.

Finns get almost one third of their electricity second-hand, after industrial users have had first dibs at it. Vesa Koivisto of Fortum (the largest utility in Scandinavia) told me that paper mills actually supply about one third of the electricity on the grid. Why?

This has led to the increased production of PV cells not only in Europe but also in Taiwan and china. China alone produces 2GW solar cells annually. In February 2010 the price of electricity using PV panel is $4.27 per watt. Today the price of photovoltaic cells of different companies is different. The General electric solar panel costs $ 228 to $385. This trend would decline with more competition.

Các dây chuyền sản xuất pin quang điện cũng tăng nhanh không chỉ ở châu Âu mà ở cả Đài Loan và Trung Quốc. Riêng Trung Quốc hàng năm sản xuất đến 2GW pin năng lượng mặt trời. Trong tháng 2/2010, mức giá năng lượng sử dụng pin quang điện là 4,27USD/watt.

Chi Thanh Ice Manufacturing Ltd based in My Tho, Tien Giang is specialized in providing ice for offshore fishing vessels. The technological process mainly uses electric. So energy saving solutions mainly focus on electric efficiency, especially in key consumption areas such as compressors and heat pumps.
