Answer 3

I take it you mean renewable forms of energy. The world desperately needs to prevent global warming, which has at least two causes. One cause is the release of polutants from carbon fuels, including coal and gas. The other cause is simply the release into the atmosphere of fossil energy previous locked up in mineral form: nuclear energy is included in this category because in the last analysis it releases energy from uranium ore.

The two big, currently available, ones that you have not mentioned are tidal energy - it is estimated that the United Kingdom could get twenty percent of its energy from wave power - and thermal energy from the ground - Iceland already exploits this where it is easy because of geysers. You have also not mentioned biofuels, including wood, i.e. burning vegetable matter that has captured solar energy via the photosynthesis process (but we then run into problems of limited land resources).

The dream of the nuclear energy is to develop practical nuclear fusion plants, which work by relasing energy from combining atoms like hydrogen rather than the current nuclear fission plants that split heavy atoms like uranium. However, this dream has been around a long time without getting much nearer reality.

A huge amount of energy is locked up in the bonds between hydrogen and oxygen atoms in water, but again ideas of developing fuel technology to use such energy are way in the future.

Given the need to use currently available technology to address the energy crisis, we really need to concentrate on wind, solar and, if we can develop fast enough, tidal power for which it is possible to build plant within the desperately short timescales imposed on us by the global warming crisis (not that enough politicians appreciate this!).

Answer 4

Gas (assuming you are talking about natural gas) is not an alternative energy source; it is very much mainstream. So are hydroelectric and nuclear power.

Some of the alternative fuels include heavy oil, tar sands, shales, ethanol (which can be made from either sugar cane or corn), biodiesel, and biomass-to-fuel.

Some of the "fuelless" alternative energy sources are geothermal energy and tide waves.

Answer 5

Biofuels (ability from flora such as ethanol), photo voltaic ability, tidal (wave) ability, hydroelectric, wind ability, geothermal, hydrogen, etc etc. I extremely have a demanding time believing that an honours student can't call a minimum of three commerce ability resources to nuclear ability.

Answer 6

fusion power, seizmic, heat from the earths core, bacterial energy cells, blah de blah, theres alot.

And surprisingly vegetable oil has been around for as long as diesel as a fuel for cars, but diesel was more accessible at the time so veg oil got the smack down, and the guy who came up with the idea died.

Answer 7

Geothermal, hydro (including tides and waterfalls), and nuclear (since it's been 20 years since a new reactor has been built in the U.S.).

There's also biomass, which is still combustion but changes what's being burned.

Answer 8

There is a lot of misinformation. Only nuclear and hydropower are EROEI viable. Learn the facts about nuclear electricity and an electric machinery economy.

Answer 9

I think geothermal's going to have to play a huge role if we're going to cut down on greenhouse gases. It's availible all over the world and clean.

Answer 10

they're working on a way to make endless energy out of seawater - something like nuclear fission. this would mean an unlimited supply of energy.

Answer 11

You need bbc bitesize. Here is the page on non-renewable energy, you need to go to the link for another page on renewable. Good luck!


Type of fuel Where it is from Advantages Disadvantages
Coal (fossil fuel) Formed from fossilised plants and consisting of carbon with various organic and some inorganic compounds.
Must be mined from seams of coal which are found sandwiched between other types of rock in the earth.
Burnt to provide heat or electricity. Coal is a ready-made fuel.
It is relatively cheap to mine and to convert into energy.
Coal supplies will last longer than oil or gas. When burnt coal gives off atmospheric pollutants, including greenhouse gases.
Oil (fossil fuel) A carbon-based liquid formed from fossilised animals.
Lakes of oil are found under land or sea, sandwiched between seams of rock in the earth (land or sea).
Pipes are sunk down to the reservoirs to pump the oil out.
Used a lot in industry and transport. Oil is a ready-made fuel.
Relatively cheap to mine and to convert into energy.
Only a limited supply. When burnt, it gives of atmospheric pollutants, including greenhouse gases.
Natural gas (fossil fuel) Methane gases trapped between seams of rock under the earth's surface (land or sea).
Pipes are sunk into ground to release the gas.
Often used in houses for heating and cooking. Gas is a ready-made fuel.
It is a relatively cheap form of energy.
It's a slightly cleaner fuel than coal and oil.
Only limited supply of gas. When burnt, it gives off atmospheric pollutants, including greenhouse gases.
Nuclear Radioactive minerals such as uranium are obtained by mining.
Electricity is generated from the energy that is released when the atoms of these minerals are split (fission) or joined together (fusion) in nuclear reactors. A small amount of radioactive material produces a lot of energy.
Raw materials are relatively cheap and can last quite a long time.
It doesn't give off atmospheric pollutants. Nuclear reactors are expensive to run.
Nuclear waste is highly toxic, and needs to be safely stored for 100s or 1000s of years (extremely expensive)
Accidental leakage of nuclear materials can have a devastating impact on people and the environment. The worst nuclear reactor accident was at Chernobyl, Ukraine in 1986.
Biomass This is decaying plant or animal waste.
An organic material which can be burnt to provide energy, eg heat or electricity. An example of biomass energy is oilseed rape (the fields of yellow flowers you see in the UK in summer) which produces oil. After treatment with chemicals it can be used as a fuel in diesel engines. It is a cheap and readily available source of energy.

If the crops are replaced, biomass can be a long-term, sustainable energy source. When burnt, it gives off atmospheric pollutants, including greenhouse gases.

If crops are not replanted, biomass is a non-renewable resource.
Wood Obtained from felling trees, burnt to generate heat and light. A cheap and readily available source of energy.
If the trees are replaced, wood burning can be a long-term, sustainable energy source. When burnt it gives off atmospheric pollutants, including greenhouse gases.

If trees are not replanted wood is a non-renewable resource.
