South Africa has a goal of having 18 gigawatts of renewable energy by 2030, so projects like this are definitely steps in the right direction. If there's one thing that South Africa has lots of, it's sunlight! 45% of the total project value was spent on "local content" to help increase the positive economic impact on the area.

Ở nhiệt độ cao hơn 60 độ C, các tế bào được làm bằng các hạt nano màu xanh và ferrocyanide sẽ được sạc. Và sau khi làm mát xuống 15 độ C, khi đó các tế bào bắt đầu tạo ra năng lượng. Ở nhiệt độ thấp hơn, chúng tạo ra nhiều năng lượng hơn lượng đã được sử dụng để sạc nó, vì vậy chúng được chuyển thành nhiệt điện.

Lithium ion batteries power everything these days from smartphones to electric cars. They’ve been a great advance in portable power storage. On the downside, their spread also makes a big contribution to electronic waste dumps often found in developing countries.

Nhiều người trong số chúng ta tưởng rằng mình đang sử dụng năng lượng đúng cách, nhưng thực ra không phải như vậy. Bộ Năng lượng và Biến đổi Khí Hậu (DECC), Anh vừa tiết lộ một số sự thật về bốn ngộ nhận mà chúng ta hoàn toàn sai về tiết kiệm năng lượng.

A new experimental “smart town” based especially around the technologies of solar energy and battery storage is being developed in Japan by Panasonic Corporation (along with other public and private partners), based on recent reports.

Bộ trưởng Bộ Năng lượng Ukraine Volodymyr Demchyshyn đã kêu gọi các ngành công nghiệp và người tiêu dùng nước này tiết kiệm điện. Do mùa Đông năm nay khắc nghiệt, kho dự trữ khí đốt và than của Ukraine đã sụt giảm nghiêm trọng, dẫn đến nguy cơ mất điện nhiều hơn trong thời gian tới.

The new displays ditch the electrodes, simultaneously making the screen thinner and decreasing its energy requirements.

Solar energy in the United States is becoming a major part of the nation's power sector as installation costs decline, Energy Secretary Ernest Moniz said.

Scientists estimate that 20 percent of all the world’s energy is spent on light, especially on illuminating towns and cities. Even in a technologically advanced country like Denmark, many of the street lamps are antiquated and energy inefficient.

Các nhà nghiên cứu tại Đại học Ohio, Hoa Kỳ đã chế tạo được pin mặt trời sử dụng chất màu nhạy quang, tích trữ năng lượng bằng cách “hít thở” không khí để phân tách và biến đổi lithium peroxide.

There will be up to £30 million in vouchers available to help with the costs of things such as insulation, double glazing, boilers and floor insulation.

Whether it was planting millions of trees, turning food waste into electricity or using smart grid technology to slash its energy use, British supermarket Sainsbury's has been slowly but surely beefing up its sustainability credentials.

“The introduction of solar as the scheme’s first renewable energy product is a fantastic addition to Warm Up North’s range of energy efficiency solutions that will allow even more households to save energy and money.

To encourage agencies, organizations and people to widely use energy saving devices and solutions, Tien Giang province has built many pilot models, supported energy saving solutions in various areas such as office lighting, public lighting, households, and application in intensive crops.

More than 14 energy conservation and 40 industrial promotion centers have been established in the whole country in order to promote saving and using energy efficiently by direct consulting for business. However, until now, half of them have only played propagandizing roles.
