By 2040, Using Current Trends, We Won't Have Enough Electricity To Power Our Computers

Will Computers Run Out of Power? Machines Could Use More Than World's Production of Electricity by 2040

Using current trends, computers will use more energy than we produce. But computing efficiency will improve to prevent this disaster happening. And the world will never dedicate all of its energy to computing power. New ways like quantum and neuromorphic computing could solve this.

The digital boom might hit a wall within 25 years because there will not be enough electricity to power all the world's computers, experts have said.
A report has warned, if current trends continue, we will be running short of electricity to power these machines by as soon as 2040.
This means radical improvement of the energy efficiency of computers is drastically needed to enable us to keep increasing the amount of computing power used around the world.
