Bloomberg) -- Converting the world to entirely clean energy needs a huge $10 trillion worth of investment, but continuing to rely on fossil fuels would cost even more, according to Elon Musk.
A massive build-out of solar panel factories to metal refineries would be required over the next 20 years to deliver renewable power generation and electricity storage capacity needed to power the global economy entirely with carbon-free energy, Tesla said in its Master Plan Part 3 document published Thursday.

The white paper sets out the detail behind Musk’s vision for a world without fossil fuels, sketched out at last month’s investor day, and calculates the cost of continuing to produce oil, coal and natural gas at 2022 rates would total about $14 trillion over the next two decades.
Musk’s envisaged global energy system requires about 30,000 gigawatts of renewable-power capacity and 240,000 gigawatt-hours of storage batteries. Those figures compare to renewables capacity of 3,214 gigawatts in 2021 and a stationary energy storage sector that’s forecast to have 1,432 gigawatt hours of capacity by the end of the 2030, according to BloombergNEF. That would represent a huge boon to clean tech firms like Tesla.
While the $10 trillion investment cost of a cleaner world is high, Musk argues that’s just a fraction of the $100 trillion global economy and entirely feasible when spread out over two decades.
“Over 20 years, it would be 0.5% of the global economy,” he told investors last month. “So this is not a big number.”
The world’s metals sector would be poised for a major demand boom under Musk’s scenario. A total of $502 billion of mining capital expenditure and $662 billion of spending on refining would be needed to produce the nickel, lithium, copper and other materials to be used in batteries and clean energy equipment, Tesla forecasts
At peak levels, the world would need to dig up 3.3 gigatons of earth every year to obtain the necessary metals for the transition to cleaner power sources. Still, that’s much less than the 15.5 gigatons that are currently extracted for the fossil fuel industries, the company said.
There’s also little prospect of the world exhausting supplies of required metals, as only a fraction of current resources are needed and higher demand will encourage explorers to look for new deposits.
Recycling will begin to meaningfully replace new metals supply from 2040, as expired batteries, solar panels and wind turbines are harvested for reuse. Other materials will be phased out or minimized: using copper instead of silver in solar panels, artificial graphite in batteries, and by completely eliminating rare earths from wind turbines.
“The electrified and sustainable future is technically feasible and requires less investment and less material extraction than continuing today’s unsustainable energy economy,” Tesla said in the document.
