i need examples of renewable energy resources for a science project. it is due in wed 3rd dec and i need the examples because i am writing a letter explaining what you could use instead of non-renewable energy resources and i need to write down all of them. please could you help peoples, 10 points if you do. and please can i not have any negative answers about looking it up, because it doesn’t give me the full works if you know what im saying.
Can Anyone Give Me All The Examples Of Renewable Energy Resources?

Solar Cell – Makes energy from the sun’s photons forcing electrons out of a cell’s silicon core.
Solar Panel – Uses the sun’s energy to heat water; the steam produced makes a turbine turn to generate electricity.
Wind Power – The power of the wind turns a turbine, which uses a generator to generate electricity.
Hydroelectric – The power of massive amounts of water being released in a place (usually a dam) creates huge amounts of electricity. Countries such as Norway are powered almost 100% by Hydroelectric power.
Geothermal – Pipes underground full of water are heated up by volcanic activity underneath the earth crust. The steam created again makes a turbine turn… and you know what happens after.
Biomass – burning specific sources such as wood or animal/human feces releases vast amounts of energy. – Note that burning feces releases methane, a greenhouse gas which contributes to global warming. Hence, identity as a renewable source of energy is debatable.
Tidal – The power of the waves generates electricity much like hydroelectric power.
Nuclear Power – Uranium atoms are split in a nuclear reactor in a reaction which is called nuclear fission. Countries such as France are powered almost entirely by this. It has no direct effect on the environment, however it produces large amounts of radioactive waste. Most people consider Nuclear power as being renewable, however it must be brought up that the supplies of Uranium and Plutonium will eventually run out.
All these sources of energy are renewable, as the source they come from will never finish. A lot of these also create hardly any waste and require few maintenance, hence they are plausible alternatives to the polluting manner of generating electricity mostly used today (namely coal powered power stations).

I doubt that you can list “all” examples of renewable energy resources. Any set of reactants for a reaction that can be regenerated with “reasonable” costs (both monetary and thermodynamic) can be termed “renewable,” imho.
I don’t see why “it doesn’t give [you] the full works”. Explain.

Wind energy – Wind turbines
Sunlight – solar cells
Water – Dams
Tides – Very rare but yes the technology exists to generate electricity thru energy of waves
Renewable energy sources can only be what you get thru nature, so I think thats about it..
Nuclear energy isnt renewable, dont include that in your project.

- wind (turbines)
- sun (solar pannels)
- bamboo. not an energy source but a good alternative to wood because it grows crazy fast.
