With the second largest tidal range in the world, about 50 feet, the Severn estuary has been eyed for years as a potential energy source, particularly as the appetite for sustainable energy sources has been growing over the last few years. The U.K. has pledged to have 40 percent of its electricity generated from renewable sources by 2020 to meet European Union requirements.

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.

Với quy mô thủy triều lớn thứ hai trên thế giới, khoảng 50 feet, cửa sông Severn nhiều năm được xem là như là một nguồn năng lượng tiềm năng, đặc biệt rất giàu các nguồn năng lượng tái tạo. Anh đã cam kết vào năm 2020 40% điện năng sẽ được tạo ra từ các nguồn tái tạo để đáp ứng yêu cầu của Liên minh châu Âu.

The ‘Global Wind Energy Outlook 2010’ (GWEO 2010) finds that wind power could play a key role in satisfying the world’s increasing power demand, while at the same time achieving major greenhouse gas emissions reductions. The 1,000 GW of wind power capacity projected to be installed by 2020 would save as much as 1.5 billion tonnes of CO2 every year.

Vietnam wants to further promote cooperation with Japan, the country’s top partner, in the spirit of strategic partnership for mutual benefit, said Prime Minister Nguyen Tan Dung. At a reception for former Japanese Prime Minister Yukio Hatoyama and the Japanese parliamentarian delegation in Hanoi on Oct. 25, PM Dung suggested that both countries should join efforts to expand trade and investment to match with their potential.

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.

DOE encourages the growth of these programs nationwide by selecting exemplary programs to receive Green Power Leadership Awards. This year's winners include 3Degrees, Bonneville Environmental Foundation, SolarCity and SunRun – recognized by DOE as the Non-Utility Green Power Suppliers of the Year – and La Plata Electric Association and Portland General Electric – recognized as the Utility Green Power Programs of the Year.

5300 điểm nạp điện cho ô tô đang được lắp đặt tại Michigan như một bước đi đầu tiên trong ngành công nghiệp ô tô điện trên toàn nước Mỹ. 1500 đại lý ô tô Chevolet trên khắp nước Mỹ cũng bắt đầu lắp đặt những những thiểt bị nạp điện nhằm phục vụ lượng khách hàng đang ngày càng tăng lên của xe chạy điện. Hãng General Motors cũng tuyên bố sẽ lắp đặt 350 điểm nạp điện khắp Michigan, trước mắt để phục vụ cho nhân viên của hãng.

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.

China's top economic planner is proposing graduated tariffs on residential electricity use as part of the nation's efforts to save energy, the National Development and Reform Commission said Saturday on its website. "A graduated mechanism will improve China's power tariff structure and spur energy conservation," the economic planning body said.

Britain held its first free eco-car show last month on London's famous royal driveway, The Mall. The event was held as part of HRH Prince Charles's latest sustainability initiative “Start”, which aims to promote positive steps to leading a sustainable lifestyle, and was opened by his “Garden Party to Make a Difference”.

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.

October is National Energy Awareness Month, and to celebrate this joyous eco-occasion, we’ve compiled a list to help you reduce your energy consumption and shrink your footprint even more. Switching to fluorescent lighting and turning the thermostat down are great energy saving starters, but if you’re looking to go the extra mile to save energy in your home, these tips are for you.

On the afternoon of October 14th, People's Committee of Hanoi discussed with the Chairman of the New Energy and Industrial Technology Development Organization (NEDO) of Japan and theMinistry of Natural Resources and Environment about preparing for the implementation of the project "Building a system to treat waste of power industry" in an area of 1 ha of Nam Son Waste Disposal Complex, Soc Son district.

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.

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.

Getting the real prototype built has been a challenge. Kitegen Research had to abandon the initial plans of building the first prototype near the town of Berzano, not far from Torino, in Italy, after almost a year of trying to persuade the local NIMBY contingent. That has generated almost one year of delay; since everything had to be moved to the new site and a completely new set of permits had to be obtained.

In honor of Blog Action Day on the topic of water, here is a bit of good news about a new low-cost, energy efficient method for purifying drinking water without the use of chlorine. Scientists at Stanford University have developed a new kind of water filter that uses a combination of silver, cotton, and electricity to kill up to 98 percent of E. coli bacteria in contaminated water. The system was recently described in the American Chemical Society journal.

With rapid industrialization, the world has seen the development of a number of items or units, which generate heat. Until now this heat has often been treated as a waste, making people wonder if this enormous heat being generated can be transformed into a source of electric power. Now, with the physicists at the University of Arizona finding new ways to harvest energy through heat, this dream is actually going to become a reality.

The world's largest consumer product maker announced Monday that it has set ambitious long-term targets for cutting the waste it produces and improving its energy efficiency. Procter & Gamble said it eventually will use only renewable energy to power its factories and only recycled or renewable materials to make and package its products.
