The plant Google invested in isn’t going to be built until the early 203. When it starts generating usable fusion energy is still TBD.

Although Google won’t have access to the power it’s buying for more than five years, making the purchase now is in Google’s interest. The move both helps CFS on its path to a functioning fusion power generator and gets Google’s foot in the door once CFS meets with success.

Alphabet's Google said on Monday it has struck a deal to buy power from a project in Virginia fueled by fusion, the reaction that powers the sun and the stars but is not yet commercial on Earth.
