Though our scientists may claim that they are inventing something new by using wind as a source of generating energy, the truth is that wind is being used for centuries for this purpose. An example of this is an article published in 1838, which clearly shows that even in those times, wind was considered an important source of energy.
Here are a few quotes that were recorded in the past, which prove that wind was always important in generating energy. Continue reading
The European Commission is holding a public consultation on the future development of unconventional fossil fuels such as shale gas in Europe. All interested individuals, organisations and public authorities are welcome to share their views on the possible opportunities and challenges that may arise from the development of such projects and on the best ways to address the challenges identified so far. The consultation is open until 20 March 2013. The consultation is available in all 23 EU languages. Continue reading
Apple’s removal prompted the city of San Francisco to instruct its city workers not to purchase Apple laptops and computers. The issue was of concern for federal procurement, where there are environmental targets for purchases; iPhones and iPads are not part of the rating. Continue reading
Humanity has acknowledged the power of the sun since prehistoric times, awed by the glowing orb whose presence creates day and whose absence plunges the world into darkness.
For all our advances in science and technology, most of the power from the sun still eludes us. NASA reports that we use only one ten-thousandth of the sun’s energy.
Photovoltaic (PV) solar electrical systems offer new and ever-changing ways to harness that energy. The term “photovoltaic” literally means light-electricity.
In 1839, French physicist Edmond Becquerel discovered that sunlight could produce an electric current. Another century would pass before scientists fully understood that this process happens at the atomic level. Albert Einstein’s only Nobel Prize was awarded for his work on the photoelectric effect. By 1958, the space program was using solar cells. Continue reading
