text: The cost of using Tesla batteries backing up wind and solar to cover occasional month long wind continental area low wind/solar events would raise power rates to  three bucks a kwh.
  
  As a result wind/solar today has to backed up to 100% nameplate with inefficient peaker plants, saving at most a few cents a kwh for the peaker plants on standby - no cents a kwh when you consider that the dirt cheap peaker displaces what would have been an expensive efficient CCGT or nuke plant running when the sun don't shine and the wind doesn't blow. The wind/solar zealot's storage scheme that using the cheapest cheapest storage envisioned for the next century would add a buck a kwh to power rates.
  
  Lotsa folks are killed by the gas backup air pollution, just less than if coal were used. Never been a politician or a wind/solar nut that gave a rats behind for the dead or figgered the death toll in their ghoulish drive to a fairy dust powered world.
