Please summarize the main points of these paragraphs in a couple of sentences.

Last month, Elon Musk announced his vision for Tesla and a sustainable future, but was vague on specifics. On Wednesday, the company laid out in detail the math behind his so-called Master Plan 3 including what the economy at large might look like in a greener future and how much it would cost compared to the alternative.

Tesla’s report finds that an economy built on sustainable energy is not only feasible, it is economically preferable. The switch would require “less investment and less material extraction than continuing today’s unsustainable energy economy,” Tesla found. The investment needed to develop a sustainable economy—based on an electrical grid and manufacturing industry powered by renewable energy and electrified transportation—would be $10 trillion, but sticking to oil, coal, and natural gas would end up costing $14 trillion globally over the next two decades, according to the paper, a difference in price roughly equivalent to the annual GDP of Germany.
