How much will energy really cost in a world that's "fully" renewable in 10-20 years? Its not much different then all the datacenters built on the Colombia river

How much will energy really cost in a world that's "fully" renewable in 10-20 years? Its not much different then all the datacenters built on the Colombia river in Washington state/Oregon so they get cheap hydro-electric power.

Alongside the thousands of other similar things like people driving large SUV's instead of fuel efficient cars before we go fully electric.
