how is electricity generated from renewable resource? Why is nuclear power a nonrenewable energy source?

Answer 1

There are several types of renewable generators: wind, solar, hydroelectric and others.

Wind and solar are quite expensive and are not reliable enough to use for the bulk of an electricity system. Hydroelectric is more reliable and economical, but most good sites are already used, so there isn't much room for expansion.

Wind farms capture the energy of wind with windmills, which turn generators to capture electricity. Solar panels directly convert sunlight to electricity. Hydroelectric stations run moving water through turbines, which spin generators to capture electricity.

Nuclear fission, which all current nuclear power plants use to generate electricity, is both reliable and economical, but it isn't considered renewable because there is a limited amount of fuel (uranium) in the earth for these power plants. Studies suggest there is perhaps enough uranium remaining in the earth for another 150 years worth of nuclear power, at our current rate of production.

Nuclear fusion, which is an experimental form of nuclear power, will have an essentially unlimited fuel source - lasting millions of years. Google "nuclear fusion" or "ITER" for more information on this fuel of the future.

Answer 2

A renewable resource is anything that can be replenished. (i.e. alcohol from corn, bio-diesel from vegetable oil, wood, etc.) Generally, electricity is generated through burning the substance, either by powering an engine that turns a generator, or by boiling water to produce steam, which then turns a generator. Wind and Hydro power use the naturally occurring motion in nature to turn generators, and solar power is generated when the sun strikes a surface covered with a special chemical that reacts to sunlight.

Nuclear power is non-renewable because it uses a process called fission. While it creates a tremendous amount of energy from a small amount of fuel, it does require fissionable material, which is expended in the reaction. Since there is only a finite amount of this fuel on the planet, and the expended fuel is useless waste, it is non-renewable. That is until we figure out nuclear fusion, which insead of "burning" fuel, actually creates it.

Answer 3

this is a huge topic.
atomic energy is produced fromn nuclear fission and nuclear fission is not renewable nor reversible, that means once radioactive nuclei has decayed ,this decay will not take place again in this nuclei. and, you cannot grow back something that will produce nuclear power! got it? and, nuclear power works on nuclear fuel! if there is no fuel on this world, then, there will be no nuclear power.

renewable resources are lot and production of energy from that is also a lot. take wind as an example, it will blow as usual so far as weather conditions are okay! so, if you produced electricity from wind, than you will never run out of it
and, if you take a river as an example, it's the same. so far as weather conditions are okay and river keeps on flowing , than you can build turbines or dams across the river and produced electricity. the same thing for wave energy and tidal energy.
got it?

Answer 4

You could burn wood in a steam generator, and create electricity that way. Then grow a forest to renew the wood you just burned.

Not all 'renewable' energy sources are high tech.

Answer 5

electricity can be generate from renewable resources such as the wind and the sun. Both windturbines and solar panels generate electricity from the wind and sun respectively. Nuclear energy is non renewable as it is from certain elements extracted from the earth. (such as uranium)

Answer 6

Hmmmmm...maybe you should have started working on it when it was assigned. The reason you have this project is to teach you how to do research using dictionaries, encyclopedias, and the Internet. YA isn't here to spoon-feed you the answers to *your* homework! With all the talk about energy sources on the news the last few years, you should have *some* inkling of what it's all about. So...take your lumps and admit to the teacher that you didn't do the work.

Answer 7

wind/water/burning trees turns a crank. That crank turns a magnet. That magnet is surrounded by copper, which gives off electrons, which gives off electricity.

NUke is non-renewable because eventually everything becomes either hydrogen or helium. Nuke waste can be plugged back into the generator, but is not as efficent as virgin elements.

Answer 8

Renewable resources are solar power, wind power, and hydro-electric power from damming waterways. The earth will never run out of those things whereas it will run out of coal, oil, gas, and uranium.

Answer 9

after the nuclear fuel is spent, it can not be used again...it is waste..however, actually very little...people seem to think nuclear produces massive amounts of waste and it is not true...
