The good news is that that time when subsidies are not
needed for solar power is coming and may be here very soon.
One problem with renewable power, such as solar PV (sun to electricity)
and wind is the cost. Presently, to be competitive with fossil fuels renewable power must be subsidized. Subsidies include tax breaks and the
renewable energy requirements that require that utilities buy a certain amount
of renewable energy, even if they have to pay more than their selling price for
the power.
