What is the amount of solar energy required to drive a 250 pound cart with a 250 pound person 10 miles? How many square feet of recharged paneling would be required?

How expensive is solar energy to yield?
What does a solar energy power sow look like and how do they work?
What are the hidden expenditure to society and the world? ( pollution, etc)

Hard homework problem I don’t know.
Above the Earth’s atmosphere, we receive about 1400 W=m2 of energy from the Sun. If you could convert 100
per cent of this energy into usable electricity, how large a collecting area of solar cells would be necessary to
yield a 1-gigawatt power sow?

I want to build a solar/wind power system, but I don’t know which product to go with. One deciding factor could be how much power each one produces.

With the environment in waning shape, everyone is looking for a way to step up and help. There are simple steps which you can take in your everyday life to help which can also subsidy you personally in cutting down on your monthly expenses as green renewable energy is cost effective! Making the transition from getting your electricity from power plants to green renewable energy is a major step in getting the ozone and environment back to their former glory, not to mention it can save you money.

How large of a solar system would I need to run 600 watts for 12 hours? Any thoughts on how much it would cost to build one? Thanks.
