A Gigafactory is a large-scale manufacturing facility designed to produce batteries and electric vehicles. The term is most commonly associated with Tesla, which built its first Gigafactory in Nevada to meet the growing demand for electric cars and energy storage solutions. These factories aim to reduce production costs and increase efficiency through mass production. Gigafactories play a crucial role in the transition to sustainable energy by enabling the production of lithium-ion batteries at a lower cost. They also support the development of renewable energy technologies, such as solar power, by providing the necessary energy storage systems to balance supply and demand.
