Amazon, Google make duelling nuclear investments [Video]

Amazon on Wednesday said that it was investing in small nuclear reactors, coming just two days after a similar announcement by Google, as both tech giants seek new sources of carbon-free electricity to meet surging demand from data centres and artificial intelligence.

The plans come as the owner of the shuttered Three Mile Island nuclear power plant said last month it plans to restart the reactor so tech giant Microsoft can buy the power to supply its data centres. All three companies have been investing in solar and wind technologies, which make electricity without producing greenhouse gas emissions. Now they say they need to go further in the search for clean electricity to meet both demand and their own commitments to cut emissions.
