Gary Said:

why solar energy is not being used?

We Answered:

The reason why it isn't being used more is because solar power is expensive. It also has only about 10-percent output whereas coal and gasoline have more than 30. Fossil fuels are cheap commodities with dense output. Further, the oil companies are doing what they can to stamp out alternative energy because they're afraid they'll lose profit.

Jeff Said:

which of the fallowing is an advantage of solar energy?

We Answered:

It is "A" all the way. Solar power is never going to run out anytime soon (not in a billion years, about 6 billion), so really it is the best way to go. All the biosphere uses solar energy. The chain starts at plants and ends at humans and other carnivores. Almost all energy sources come from the sun, so why not just use the sun in the first place? (Water: Evaporation from sun; Wind: Unequal heating from sun; Wave: Ocean would be frozen without sun)
