“Solar thermal power with storage will soon be cheaper than new coal-fired power stations according to US Department of Energy projections." This bit of info from an Australian site called "Beyond Zero Emissions.org." This is an organization of over 200 groups of Aussies who believe in getting to the point of using 100% renewable energy by 2020.
They have a radio show, discussion groups, political campaigns, etc. in an effort to bring about a severe reduction in the use of energy resources such as coal.
Here's a link to their article informing fellow Aussies about the use of solar thermal power or "Baseload"as they're calling it. By using molten salt storage to create steam to run a turbine which provides energy during the night as well as the day. Many people are still not aware that this technology exists. They only hear about solar panels on residential rooftops and fear cloudy days make solar power weak and undependable as an energy source.
Solar Power All Through The Night.
