Solar power may soon bring the Web to remote areas
One laptop per child" was the ambitious promise a group of MIT faculty members made to the world in January last year. The idea to develop and produce millions of simple, Internet-capable $100 laptops and give them to the poorest kids on the planet sounded appealing. But just how children in remote villages in sub-Saharan Africa were supposed to hook up to the Internet was unclear. The solution may come out of thin air. Literally. All you need is a rooftop and the sun, claim the inventors of a solar-powered wireless device.
Solar power in schools saves money, renews energy
he first solar-powered school in the Poway district will open in August, with solar energy powering 50 percent to 60 percent of the school's electrical needs. The solar photovoltaic system will lower electrical costs for the Monterey Ridge Elementary School by $30,000 to $40,000, said Doug Mann, director of facilities for Poway Unified School District. The school is located on 4S Ranch Parkway, off Rancho Bernardo Road, and was designed by NTDStichler Architects in San Diego, and built by Temecula-based Edge Development Inc.
Everything You Wanted To Know About Solar Power and Were Afraid To Ask
Global electricity usage is expected to increase from 14.8 trillion kWh in 2003 to 27.1 trillion kWh by 2025, according to the U.S. Department of Energy’s Internal Energy Outlook 2005. Approximately 65.7% of the world’s electricity is currently produced with fossil fuels. As demand for electricity continues to increase, the electric power industry is facing several challenges. Industry and governments are considering alternatives to traditional fossil fuels to address these challenges, including renewable energy sources and technologies.
Worldwide Solar Power Generation Growing Fast
According to speakers at the 21st European Photovoltaic Solar Energy Conference and Exhibition in Dresden, world wide solar power generation is expected to increase by 25 per cent this year. In 2005, worldwide turnover in the sector was 5.8 billion euros (7.4 billion dollars), according to Heinz Ossenbrink, head of the Renewable Energy Department of the Institute for Environment and Sustainability at the EU Research Centre in Ispra, near Milan. He told the conference that drastic increases in oil prices and the growing awareness of business, politics and consumers of the limited availability of fossil fuels has given the photovoltaics sector a big boost.
World's largest solar power plant
Germany isn't the sunniest of countries, but it is a hotbed of solar power. And now it's home to what the companies involved are calling the world's largest solar electric power plant. On Friday, Silicon Valley-based SunPower marked the dedication of the Gut Erlasee Solar Park, a 12-megawatt facility located amid cropland near the Bavarian town of Arnstein.
Solar power to shine in coming decades
he tiny solar power industry is booming and could generate 2.5 percent of world electricity by 2025 in a shift from fossil fuels, a report by a business group and environmental lobby Greenpeace said on Wednesday. "Solar power... would represent the annual output from 150 coal-fired power plants" by 2025, the European Photovoltaic Industry Association and Greenpeace said. The report said photovoltaic systems, which turn sunlight into power, now generate 0.05 percent of world electricity and could rise to 2.5 percent in 2025, the main horizon for the report, and then leap to 16 percent in 2040.
Sharp sees solar power costs halving by 2010
Japan's Sharp Corp. the world's biggest maker of solar cells, expects the cost of generating solar power to halve by 2010 and to be comparable with that of nuclear power by 2030, Sharp's president said. "By the year 2010 we'll be able to halve generation costs," Katsuhiko Machida told Reuters in an interview on Thursday. "By 2020 we expect a further reduction - half of 2010 - and by 2030 we expect half the 2020 level. "By 2030 the cost will be comparable to electricity produced by a nuclear power plant," said Machida, speaking on the fringes of the IFA trade fair in Berlin, the world's biggest consumer electronics fair.
Mimicking nature for cheaper solar power
A research team in Sydney has created molecules that mimic those in plants which harvest light and power life on Earth. "A leaf is an amazingly cheap and efficient solar cell," said Dr Deanna D’Alessandro, a postdoctoral researcher in the Molecular Electronics Group at the University of Sydney. "The best leaves can harvest 30 to 40 per cent of the light falling on them. "The best solar cells we can build are between 15 and 20 per cent efficient, and expensive to make.
