California approves its first molten salt solar power plant

One of the biggest problems with solar energy is that the sun doesn’t shine 24 hours a day. This means that unless users are only planning on using electricity when the sun is shining, some form of energy storage system is required. Since storing excess electricity in rechargeable batteries isn’t really practical for large-scale solar power plants, another storage system is needed. U.S. utility-scale solar project developer SolarReserve has now received approval for the first solar power plant in California that uses molten salt technology to store the sun’s thermal energy as heat so it can generate electricity when needed, at any time of the day or night.
