130 percent more than wind energy energy
solar cells generate electric currents directly from the sun light
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.
16000kwh
There is enough energy in ocean waves to power everything in the world. However the technology is still experimental and expensive. Solar and wind power is going to be cheaper and more sustainable.
Yes. If there is any light, even on a cloudy day, a solar panel can generate power. But the amount of power generated is much less when the solar panel is not in direct sunlight (about 90% less).
Most countries burn fossil fuels to generate electricity.If they used solar power to generate electricity, thenThey would not have to use so much fossil fuel.Solar Energy itself does not reduce the use of fossil fuels. But the use of solar energy should hopefully reduce the need of fossil fuels to create energy, so therefore the more we can use solar power as an energy source instead of fossil fuels, the more we reduce the use of fossil fuels.

I assume they come in different sizes, but a typical commercial solar panel generates about 50 watts.
4 Watt-hours
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!
Nearly 42 million megawatts (MW) of power.
