Multiple proposals from Democratic presidential candidates are calling for a full transition from fossil fuels to renewables over the next 10 years. Independent analytics firm Wood Mackenzie was interested in the numbers behind those proposals. It found a transition would take closer to 20 to 30 years. Dan Shreve, head of global wind energy research at Wood Mackenzie, co-authored the report.
"We're talking about 1600 gigawatts (GW) of wind and solar resources that would need to be procured, sited, permitted and then installed and grid connected," Shreve said, adding all of this would cost $4.5 trillion in new investment - an amount that doesn't surprise him.
Shreve mentioned 1600 GW is the total capacity required to fully transition away from fossil fuels. Current capacity would need to increase tenfold to meet that. Wind and solar capacity sit at 164 GW right now.
The Mountain West would not be the center of demand for increased renewables, but it would be a player in generating and supporting new renewables, according to Shreve. Already, Montana, Wyoming and Nevada are among the top ten states for potential wind capacity and Utah is among the fastest growing solar states.
Then there's the support role. "There is a need for some long-haul bulk high voltage transmission to move renewable energy from areas of high resource to areas where there is high load demand," Shreve said.
For example, in our region, that means building the system to transport energy that we produce to the west coast.
Coal generation hit a 47 year low this past April.
