the sun gives about 15000 kilo calories in one square foot. when it reaches earth it will have the power to glow a 100w bulb.
less then 1%
130 percent more than wind energy energy
In some parts of the world, there is NO sun (to speak of) for as much as six months! In these areas, solar power is out of the question, unless there is a monstrously large storage system that can hold the energy during the six months of sunlight!

They have been the most efficient energy source available
In 2012 the annual global solar energy production topped 100 000 Megawatts. That is 274 Megawatts a day. At peak power that is the equivalent of 100 large nuclear power plants.
The Earth receives about 174 petawatts of solar energy from the sun. This energy is enough to power all human activity on the planet many times over.
There is not much to dislike about solar energy.
The cost of an energy source varies considerably. It depends upon how much energy you want, as well as the type of energy generation you want; solar power and diesel power have different costs, for example.
