How much energy is lost as heat, and how does this compare to other forms of power generation?
In: Engineering
Efficiency and “density” don’t really matter when your fuel is free, except as they affect cost/KWh.
If tomorrow someone invented a solar panel that was 1/2 as efficient as today’s, but 1/4 the cost, that would be a great advance.
We have all the space we need to site solar and wind generators, and putting them somewhere often does not destroy the existing use of the space. For example, put solar panels on frameworks above parking lots and highways.
