What makes energy from winds, wave and solar power different from other kinds of energy we use, like oil

All of the three are making less pollutants than the normal types of fuel ( if you need more in depth scroll down a little)

Winds

pros
less capital
less polution

cons
cannot be transported or used directly

Wave

pros
completely renewable
widely available
environmentally friendly
no damage to land

cons
may affect marine ecosystem
highly dependant on wave length

Solar

pros
can be everywhere and anywhere
efficient way to heat materials
produces clean fuel
versatile

cons
sometimes only small amounts of electricity/fuel are made on less sunny days

Hope this helps!

Winds, Waves, and Solar power are all natural resources. Wind, Ocean waves and The sun all come naturally. Unlike oil which you have to dig up. Also there's no pollution from these kinds of energy.
