This would require no major upgrades to the grid, but would be done by spreading wind and solar installations across large geographical areas to balance out the variability of the power generation. Ok, but what about the other 65%? This…
It’s just 10MW now and the power is expensive. But it’s basically a prototype. Presumably prices for solar thermal will drop as the technology improves and economies of scale take effect.
The purple juice from the berries can be used to coat inexpensive fiber-based solar cells, increasing efficiency, say researchers. Pokeberries proliferate even during drought and in rocky, infertile soil. That means residents of rural Africa, for instance, could raise the…
A retired mechanic in Brazil, Jose Alano, has invented a simple, effective solar hot water heater using discarded plastic bottles. The idea has spread and there are now thousands of them installed. The alternative water heater can provide power savings…
