There are already very large pumped storage hydro plants in California.
To pass the grid scale electrical production test:
1.The source must provide large amounts of electrons (it must be dense) -parenthetically, this is what makes petroleum derived gasoline and diesel such great transportation fuels. (along with portability).
2.The power must be reliable and predictable.
3.The electrons must be dispatchable (high or low amount must be generated on demand)
4.It must serve one or more grid demand elements(base load, load following and peak load).
5.The utilization of environment must be minimal and compactness is a must, or it is non-green and damaging the environment.
6.It must be economical
Solar/wind fail absolutely on 1 through 4, and are very questionable as to
5&6.
The inherent energy density problems with wind/solar cannot be overcome. Wind Turbine spacing is 1 per 50 acres. I'm currently working a 3,000 acre West Texas ranch for the development of horizontal oil wells. The ranch currently has 24 producing oil wells and 12 wind turbines. The incidental natural gas production from ONE of the oil wells will produce more electricity than all TWELVE wind turbines combined.
The efficiency of wind turbines is very good and approaching theoretical limits (Betz Limit). The only way really now to squeeze more electricity out of a turbine is to make the blades longer. At this point, the ratio to increased blade length to electrical production is about 3:2. Remember, that the longer the blade, the higher your spacing requirement between turbines. This makes increasing blade length a self-defeating proposition.
