エネルギー貯蔵
Energy storage is becoming a more prominent issue because photovoltaic solar panels can only generate electricity during daylight hours and thermal solar installations can only store energy for up to 10 hours, leaving a window in which the state's energy production must be generated from other sources (natural gas, coal, and nuclear). To remedy this, different sorts of power storage solutions have been proposed such as batteries, compressed air, and ice generation.
