Elon Musk revealed the third part of Tesla’s “Master Plan,” in which the company will lead the global effort to eliminate fossil fuels and convert the world to sustainable energy. The plan was outlined during an investor event Wednesday held at the company’s Gigafactory in Austin, Texas.

Master Plan 3 includes adding renewable power to the existing grid, producing more electric vehicles, installing heat pumps in homes and buildings, using high-temperature heat delivery and hydrogen for industrial applications, and building sustainably fueled planes and boats. Musk’s plan is to create “a sustainable energy civilization.”
