Ways of harness energy from wind, water and sun? HELP?

Question

What are some ways of harness energy from wind,water fire/sun and earth?

Answer 1

Wind - Wind turbines

Water - Hydro electricity (water wheels)

Sun - Solar pannels

Earth - Geothermal energy





Just finished doing these in school. I would reccomend Google to find out more :)

Answer 2

Wind energy is fairly straightforward; a turbine turns the kinetic energy from the blades (moved by the wind) into electricity. For solar power, there's two strategies you can use: you can use photovoltaic cells to turn sunlight directly into electricity, or you can use mirrors to direct light at a reservoir of water, and use the heated water directly for heating or convert the heat into electricity. You can get geothermal energy from the earth in certain regions, but not all. (Iceland being the poster child for geothermal energy.)



Energy from water is a little more varied. You can use tidal energy, where the kinetic energy of the tides is turned into electricity. You can build a dam (or just a waterwheel) and turn the flowing water into electricity. You can exploit the potential between salt and fresh water, too.

Answer 3

Windmill farms are the best way to turn wind into electricity. Hydro dams do the same with water. Earth we can use the trees as long as what we use are re-planted to heat homes. The sun we can take the ray through solar panels to heat and light homes. They are all becoming more popular with becoming free from over use of fossil fuels and conserving the environment at the same time

Answer 4

wind generators water wheels in flowing water water falls making steam with the hearth geothermal from the earth image voltaic cells for electric from the sunlight a liquid to be heated in lack field to get warmth from the sunlight

Answer 5

Wind turbines



Solar panels



CSP (concentrating solar power)



WEC (wave energy conversion) devices



Geothermal

Answer 6

Call Captain Planet! He's a hero! He's gonna take pollution down to-

...oh, energy.

...never mind.

Answer 7

yes
