We have all the technology right now that we need to power the U.S. state by state and the world with solar, wind, and water power. No burning coal or oil or fracked natural gas and no nukes. No need for any new destructive and hazardous methane pipelines. No waiting for batteries. All we have to do is get on with it.
Stanford University researchers led by civil engineer Mark Jacobson have developed detailed plans for each state in the union that to move to 100 percent wind, water and solar power by 2050 using only technology that’s already available. The plan, presented recently at the AAAS conference in Chicago, also forms the basis for The Solutions Project nonprofit.
“The conclusion is that it’s technically and economically feasible,” Jacobson told Singularity Hub.
The plan doesn’t rely, like many others, on dramatic energy efficiency regimes. Nor does it include biofuels or nuclear power, whose green credentials are the source of much debate.
The proposal is straightforward: eliminate combustion as a source of energy, because it’s dirty and inefficient. All vehicles would be powered by electric batteries or by hydrogen, where the hydrogen is produced through electrolysis rather than natural gas. High-temperature industrial processes would also use electricity or hydrogen combustion.
The rest would simply be a question of allowing existing fossil-fuel plants to age out and using renewable sources to power any new plants that come online….
“The greatest barriers to a conversion are neither technical nor economic. They are social and political,” the AAAS paper concludes.
For Georgia, that’s 40% solar PV plants, 35% offshore wind, 13% rooftop PV (6% residential and 7% commercial), 5% concentrating solar plants, 5% onshore wind, and 1% each wind, tide, and conventional hydro power. Plus 210,200 construction jobs and 101,000 operation jobs. And saving $14.3 billion per year Continue reading
