Luckily, the Department of Energy (DOE) is betting on, if not a completely green energy future, at least a greener one. The DOE has approved up to $62 Million in funding for concentrating solar power (CSP) research and development. CSP technologies work like this: the sun's energy is concentrated and captured as heat – the heat then drives a turbine to produce electrical power the same way a coal or nuclear plant would. Some CSP plants include energy storage devices, allowing them to provide electricity even when the sun isn't shining – i.e., nighttime – which is when a lot of PEVs will likely be charging.
The DOE has selected 13 projects that will seek to improve CSP component and system designs to bring them to a level of energy production on par with coal-fired plants, about 18 hours a day.
