Switching The World To Renewable Energy Will Cost $62 Trillion, But The Payback Would Take Just 6 Years - CleanTechnicahttps://cleantechnica.com/2022/09/06/switching-the-world-to-renewable-energy-will-cost-62-trillion-but-the-payback-would-take-just-6-years/The researchers looked at onshore and offshore wind energy, solar power, solar heat, geothermal electricity and heat, hydroelectricity, and small amounts of tidal and wave electricity. Batteries were the most common electricity storage solution, with the team finding that no batteries with more than four hours of storage were necessary.
The researchers say switching to renewable energy would avoid utility grid blackouts and save consumers trillions of dollars. One of the main reasons for that finding is that the combustion-based energy systems most countries rely require a lot of energy just to function. In switching to a clean, renewable energy system, Jacobson states that worldwide energy usage would go down by 56% immediately.
Those savings are attributable to the efficiency of clean energy over combustion systems, as well as the efficiency of electrified industry. There would no longer be a need to explore for oil, coal, and gas, drill wells or dig new mines, transport oil to refineries, build and maintain pipelines, or truck petroleum products to end users, according to My Modern Met.

The cost of making the changeover to 100% renewable energy would be a staggering $62 trillion. Wow! That is a ton of money, people. But here’s the thing. Jacobson and his team say the savings from switching the world to 100% renewable energy would be $11 trillion a year. In other words, the initial investment would be paid back in just 6 years! Many people have a hard time distinguishing between an investment and an expense. They tend to see that $62 trillion as an expense and ignore the payback.
There’s one other aspect of renewable energy that you can’t put a price on but it’s extremely valuable nonetheless — energy security. Nations that generate their own electricity don’t need to be at the mercy of lunatics and despots who can decide at any time to cut off the supply of oil, or unnatural gas, or coal. How much is that worth? It may be hard to answer that question, but it is clearly not nothing. The people of Europe are facing a long cold winter because the supply of cheap methane from Russia has ended abruptly.
