Floating wind turbines are a little more complicated and require higher initial costs. But a new study, Project Deepwater, by the Energy Technologies Institute (ETI) in the UK has found that due to their greater ability to access stronger and more consistent winds deeper out at sea, they are more economically efficient in the long term.

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 Such high energy consumption is attributed to the use of outdated technologies and equipment as well as insulated steel furnaces.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

Prominent corporations are paying special attention to go green and create a conducive environment for clean and green energy. Walmart too is taking appreciative steps in the field of alternative energy. In the year 2007, Walmart entered into a partnership with Environmental Defense Fund (EDF) to provide a thrust to the photovoltaic technologies. It was related with thin-film solar. They aimed for taking it out from labs to the real world.

Last year, the Ocean Power Technologies (OPT) company has developed a tidal power generator that has now been connected to the energy grid at the Marine Corps Base Hawaii as part of the firm’s program with the US Navy to test wave energy technology, giving the US their the first-ever grid connection for a wave energy device.

A delegation representing 15 Finnish enterprises said here on Tuesday they wanted to look for local partners to develop renewable energy, wastewater treatment, industrial waste management and other environmental technologies. Some of the Finnish companies introduced their clean technologies at a seminar held here on Tuesday were Neste Oil Corporation, Cargotec, GD Power, Kemira, Fincumet, YIT and Outotec.

Starting early to develop China's own energy-efficient and new-energy vehicles a decade ago, China now has an established industry with the research and development of three types of these vehicles and three key technologies at its core. Zhang Laiwu, vice science and technology minister, made the remark Thursday at a press conference in Beijing, adding that China' s industrial pattern of green vehicles was relatively unique in the world, because of its early start to develop these vehicles.

Các cách thức mới nhằm tạo ra các tấm pin năng lượng mặt trời hiệu quả hơn thì vẫn đang diễn ra hàng ngày. Bộ phận mới trong thiết bị này đó là một tấm dán lớn, trong suốt được gắn ở phía trước tấm pin nhằm tăng sản lượng điện năng lên khoảng 10%. Genie Lens Technologies là hãng chyên sản xuất các tấm dán mỏng bằng chất liệu polyme như thế này.

New and unique ways of making solar panels more efficient in power generation are coming to light every day. The new kid in the block of one such device is a large transparent sticker applied to the front of the panel which increases the power output by about 10% or so. Genie Lens Technologies is the firm which has developed these polymer film stickers. These polymer films are imprinted with special kind of microstructures.

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.

Watch out everybody, turbines are growing. According to the 2009 Wind Technologies Market Report (WTMR) released this August by the US Department of Energy, a turbine’s average nameplate capacity (the maximum output a turbine can produce), hub height (distance from the ground to the spot where the blades converge), and rotor diameter (diameter of the circle traced by the blades as they rotate) have all increased during the past year.

Microalgae could be one key to a more sustainable, less risk energy future for the U.S., and researchers are working on several fronts to find a low cost, high efficiency process for extracting renewable biofuel from the tiny plants. At Unitel Technologies, Inc., researchers have developed a microalgae – to – biofuel process that leaps over at least one obstacle, and that is the large amount of energy currently required by most oil extraction methods.

Many passionately believe that clean coal is not the answer to decreasing carbon emissions or increasing the supply of energy. In fact, since Obama's decision to set aside $2.4 billion dollars "to lead the world in CCS technologies," disagreements (and for that matter, debates) have surfaced about its legitimacy as a true carbon-fighting, energy-producing solution.

Fourteen years ago, the Hanoi Towers at 49 Hai Ba Trung, Hanoi had Air Handling Units (AHUs) installed for the 13-storey tower consisting of office and shopping space, and Inverter Multi Systems installed for the 25-storey apartment tower. At that time, AHUs and Inverter Multi Systems were modern technologies.

EU’s ‘Clean Sky’ – the 1-6 billion euro research project – with 86 participating partners from 16 nations – has goals like developing unique application-specific technologies and evaluation and advancement of the entire aeronautic system.

A meeting was held in Hanoi Monday for Vietnamese enterprises and firms from Maryland State, US, to seek trade partnership. The meeting, hosted by the Vietnam Chamber of Commerce and Industry, offered an opportunity for local firms to learn about the US technologies and latest applications in the environmental area.

While they may sound nuts, these wild and innovative ideas could be the future of mobility. From electric cars that charge without wires to remote-controlled commuter convoys, plenty of far-fetched technologies are in the works that could green up the way we drive and make our roads do more than just lie there.

Cobalt Technologies this week said that it has made a breakthrough in producing biobutanol from beetle-killed lodgepole pine feedstock. Cobalt claims to be the first company to produce a drop-in replacement for petroleum and petrochemicals from beetle-affected lodgepole pine.

But it's also one of the dirtiest with the world's 2,300 coal-fired power stations contributing around 40 percent of all man-made emissions, according to the World Coal Institute. Their continued use enrages many environmentalists who argue that we should be phasing coal out. But the coal industry is pinning its hopes on the rather oxymoronic-sounding "clean coal," which has become the umbrella term for a range of new technologies that share the aim of cleaning up coal in the 21st century. Earth's Frontiers takes a look at the options:

“This decade is crucial for effective policies to enable the development of solar electricity,” IEA Executive Director Nobuo Tanaka said. “Long-term oriented, predictable solar-specific incentives are needed to sustain early deployment and bring both technologies to competitiveness in the most suitable locations and times.”

Một loại tàu lặn hoạt động bằng bàn đạp có khả năng lặn sâu 30m đã được Công ty Marine Innovative Technologies Ltd (MIT) ở St.Petersburg, Nga, chế tạo. Tàu lặn này phần lớn được làm bằng kính acrylic đặc biệt giúp người ngồi bên trong ngắm cảnh dưới nước.
