That is the government doc. As all global warming document it is highly skewer they way they want you to believe.
Independent evaluations show a lot longer EROI, even infinite in cases of northern latitudes, e.g. Germany.
There is plenty of independent confirmation of solars EROI, international if one looks at the IEA. Putting panels up in Seattle or northern Germany makes for a long time for break even based on climate alone. Put those same panels in the desert southwest or Southern Spain and they break even in under 4 years and then make power for 21 years more. Thin film cells have a year break even in sunny climates.
My cells paid for themselves in under 4 years cost wise. You can’t have a oil well, refinery and fuel production plant in your backyard. I can most certainly fuel a Tesla off my panels my weekly mileage needs would be a few hours of the output off my panels. That is independence at it’s finest the gov cannot shut off the great thermonuclear fireball in the sky they can at will shut down gas pumps. Kartina and Harvey come to mind. If the gov decided overnight that they wanted to end gasoline sales they only need to tell the dozen or so refineries to lock their gates or else in two or three days there is not a single gallon for sale. Same for the gas grid. Tell atmos or Chesapeake turn off the gas main pumps or else and guess what in a few hours there won’t be anymore natgas on tap. It’s foolish to think that the gov doesn’t have the power to stop the sale of fuels they certainly do have the power and the force needed to do so. Can they go to every rooftop and smash the panels sure but not as easy as locking a few gates under armed stormtrooper guard or clicking a few computer keys to shut off pipeline valves and pumps.
