Answer 4

I think Sleep or and b. solar

Answer 6

nuclear energy.

heat energy comes from the sun

thermal energy comes from the sun

chemical energy comes from chemicals formed using the sun's energy

the sun's energy comes from nuclear reactions inside of it. on the inside of the sun, hydrogen atoms are fused together to form helium (nuclear fusion). On the surface of the sun, helium atoms are split to form hydrogen atoms (nuclear fission)

Answer 7

the ultimate source WOULD be solar-electric.  

but the technology we currently have for harnessing the suns unwavering and FREE energy is not up to the task...yet.

but, I think if we concentrated on a combination of solar, wind, geo-thermal and hydrodynamic energies, depending on the location and the resources available, we can end pollution and waste, not to mention reduce the cost of running our cities and homes.

instead of pilling up the profit from coal and oil energy in the pockets of the CEO's of those companies, it should be going into research and development of cleaner and more renewable energy.

Answer 9

solar energy

Answer 10

wind to battery power gets the nod from me

Answer 11

Solar energy.

Without the sun, all life dies.

Answer 12

b. solar energy.

The sun imparts about 2 horsepower per square meter across the surface of the earth's atmosphere facing the sun.  The amount of energy that we (humans) generate in total on the earth is insignificant in comparison.  This solar energy heats the planet (obviously) and drives all the natural cycles of our planet.

Answer 13

solar is the way to go. Chemical (fossil fuels) are most common. people are being ******* **** holes and are turning to nuclear energy. What idiots.
