It's the price that matters Lee.
Only if you can manufacture and site sufficient solar farms and wind farms.

You don't have to pay for the billions of cubic meters of wind that blows through a turbine.
You do have to pay for the structure, the increased demand on materials. Cement, steel, copper, silica.

Light on the other hand is infinitely dense in energy if you consider it as a wave.
And the capture of that has costs associated.
I have posted this before. You seem to have forgotten -
"London Array wind farm to the south of England.This is the world’s largest offshore wind farm and according to its owners will generate “enough energy to power nearly half a million homes.” Its total capacity is 630 MW covering a total of 100 km2, and is expected to have a capacity factor of 39%. I
n other words the power density of the London Array will be 2.5 W/m2."
" As a result
the highest power density achieved is around 20 W/m2 in desert solar PV farms, whereas solar farms in Germany generally achieve 5 W/m2."
"Power densities are comfortably above 100 W/m2 after accounting for mining etc. And conventional power plants often have power densites in excess of 1000 W/m2. A simple example of this higher power density is this small propane powered generator, providing in excess of 1000 W/m2. This is far in excess of the power density of any conceivable new method of generating renewable energy. "

Does that mean dimmer lights at night not to exhaust the clean energy battery supply....?!
