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 demand for electricity generally peaks at about 6:30pm, when production from solar is usually zero.
