Tesla’s Gigafactory in Nevada will be powered by a 70-megawatt solar farm on the roof. It will be seven times larger than the world’s next biggest rooftop solar installation. The plan for the Gigafactory is to not directly consume any fossil fuels. The solar installation is supposed provide most of the power needed. Having an all-electric facility will allow for greater efficiency and zero carbon emissions. The buildings heating will predominantly be provided by waste heat from the battery manufacturing process. A closed-loop water system will recirculate 400,000 gallons of water which reduces the fresh water usage by 80 percent in comparison with standard processes.
