Five Fatal Flaws of Solar Energy
The sun is the most important energy source on Earth. Solar energy powers the growth of all trees, grasses, herbs, crops and algae; it creates the clouds and powers the storms; it is the source of all hydro, photo-voltaic (PV), solar-thermal, bio-mass, and wind energy. Over geological time, it also creates coal.
PV solar panels are useful in remote locations and for some portable applications. With enough panels and batteries, standalone solar can even power homes.
But solar energy has five fatal flaws for supplying 24/7 grid power.
Firstly, sunshine at any spot is always intermittent and often unreliable. Solar panels can deliver significant energy only from 9am to 3pm – a maximum of 25% of each day. Solar can often help supply the hot afternoon demand for air conditioning, but de
