Critics of renewable energy often cite two reasons for why they think a transition from fossil fuels will take half a century. Firstly, that sources of renewable energy are too intermittent to be reliable and secondly, that governments cannot bear the costs of switching entire economies to clean energy.

The mini electric vehicle being made by China’s biggest carmaker is now outselling Tesla two to one.
To feed 10 billion by 2050, the world’s farmers will need to increase food production by up to 70%. Bring in the robots.
Bitcoin mining is mainly driven by renewable energy — hydro (by far the largest component), solar, wind and geothermal. Period.
In fact, we’ve estimated the lower bound of renewables penetration in the bitcoin mining energy mix to be 77.6%.
From 2018, but it’s likely gotten better since then.

The unit has yet to actually send power directly back to Earth, but that technology has already been proven. If the project develops into huge kilometers-wide space solar antennae, it could beam microwaves that would then be converted into fuel-free electricity to any part of the planet at a moment’s notice.
Scientists working for the Pentagon have successfully tested a solar panel the size of a pizza box in space, designed as a prototype for a future system to send electricity from space back to any point on Earth.
Whoever manages it first, we are on the cusp of a new age sparked by fusion giving more than it gets (producing more energy than it uses), then miniaturization for practical use and mass manufacture. That would essentially mean that we have access to an infinite, cheap, safe, and clean energy source. No more coal. No more nuclear waste. Massively less global warming. Even better, given the fact that the world runs on an energy economy built around energy scarcity, we will essentially become a post-scarcity civilization. And THAT my friends is a permanent, impossible to overstate game changer. For EVERYTHING and EVERYONE — FOREVER.
But first, scientists need to see if it’s ready.
