From Fusion to Geothermal, Tech’s Clean Energy Bets Are Multiplying

Nuclear isn’t the only source of carbon-free power that has energized the tech industry.

For years, solar and wind have been mainstays for tech companies looking to reduce the greenhouse gases emitted by their data centers and other operations. The tech industry is also forming partnerships to build power plants that use new technologies to tap geothermal energy, some of which are already operational.

The most speculative, and promising, technology getting funding is nuclear fusion—a method of releasing energy by mashing atom nuclei together. Traditional nuclear reactors create energy by splitting atoms apart. Here are the carbon-free power sources garnering the most interest from tech companies.
