Solar energy: “googling” your roof Despite increasing talk about renewable energy, many people remain far removed from what’s going on. To tackle this, various projects have been developed over the years helping users to better understand and use green energy sources.
Green energy and politics: crowdfunding to the rescue? The Paris climate change pact , which entered into force last year, was announced with a huge fanfare. The deal aims to limit the rise in average global temperatures to “well below” two degrees Celsius, compared to pre-industrial levels.
Industry under the sun Where’s the best place to set up a factory in Europe? Athens , of course! As unexpected as it may seem, the Greek capital ranks first in a special list of 40 regions across the EU , for conditions ideal for the integration of renewable energy, notably solar, in manufacturing activities .
Crossing borders to crowdfund renewables Renewable energy crowdfunding involves three different parties: the fundraising platform, the investors who generally expect a return, and project developers needing money. They may come from different nations .
Power of the Sun. Dirt cheap In the late 1980s, the German-born chemist Michael Grätzel literally tied his name to an invention that is hailed as a revolution in renewable energy .
Smart grid: A grid suitable for renewable energy Traditionally our electricity grids were designed to move power from large nuclear and fossil fuel power plants to consumers, but renewable energy will see changes to allow smaller power generation from wind and solar to be hooked up to the grid.
Global solar radiation map Renewable energy sources play an important role in securing future energy supply and mitigating climate change.
Nano-tuned Solar Cells The sun has enough power to supply the whole earth with energy. But as long as renewable energy is more expensive than energy produced by coal or nuclear plants, solar energy won’t be first choice.
