These days finding alternative energy sources is a big issue world wide because of global warming and the fact that natural resources like coal could eventually run out. Also there is the problem of what to do with all the waste we produce in modern communities.
Please go to the following website and read the article about using methane gas from sewerage to produce electricity. Make sure you read for understanding. After you have skimmed through the article go back and check you understand the keywords. Don't forget you can use an online dictionary to help your comprehension... THEN...
- Do you think this is a good idea... and if so why... if not why not...
- What other forms of energy could we use to produce power (i.e. electricity) instead of using coal?
- What is wrong with using power to produce energy? ... If you can't answer this question off the top of your head do an Internet search to get your answer. If you type in something like "coal powered electricity pros and cons" into Google you'll find plenty of sites to look at.
Please post your answers to the comments section of this blog.

1)Yes, I think it is a good idea. Because it is using renewable sources so it can use over and over.
2)Methane gas

1. Do you think is a good idea... and if so why... if not why not...
-I think it's yes. Because actually sewerage's water is really dirty, and everyone don't want to use them. If that dirty and useless's water can change electiric, it is really good idea! And you know, everywhere need a lot of electiric. I think that way is really good idea in everywhere.
2. What other forms of energy could we use to produce power(I.E. electricity) instead of using coal.
-Of course, sunshine. I think sunshine is never become dangerous and useful. Everywhere even very poor country, and specially in summer's sunshine is really strong. If we save sunshine in summer you can use everytime. Even winter. And notmal day you can save sunshine in daytime and you can use all night. I think sunshine is really useful.

1.Do you think this is a good idea...and if so why , if not why not?
yes, it can decrease pollution
2.what other froms of energy would we use to produce power instead of using coal?
Water, wind and sun.

3)Coal is non-renewable gases, it is natural resouces. It may used use up in the future. Using coal cause air pollution problem, and it affect people's health. Buring coal will produce carbon dioxide and it cause Golbal warming more serious, it will affect the whole world.

1)Yes, I think it's a good idea, because it is renewable resources, it can use again and again.
2)Solar power, wind power, water power, hydroelectirc power

1. I think it is really good idea,because, nowadays many peole use the electricity .If many peole contiune use the a lot of electricity ,after we will not have electricity. We can not use the this.
Sometime, many rain came in the ground. Than we got a lot of water. When we got waters, we can use dam and than, we shut in dam.
But, many time we use this method, we will not have water.
2. We can use air, water,sunshine,geithermal energy instead of coal.
If you think about this, you can get many thing.
we always use the coal energy. But, we don't have many coals. Coals is linitation.
We need fitness when we use coals.
We need development about energy.
3. If you use the coal, maybe air will pollution.
But, we need many energy.
So, we can't anything about that.
Just, we can develop adout clean thing.
1.Yes ,I think is a good idea. Because they can make power and energy . Can potect the environment .
2.Can use the wind for the power , even sun can too.
3.
1. I think it is good idea because if it would be originated
more factories than now, they will help us very much.
2. Window, sunlight, water and atomic energy.
3. It will destroy anything for example the ozone layers. But I think we can’t help it, because we live in the earth with rather expenses. So all we will have to do is how we will cut the expenses, I think.

3. Gas, coal or aome power like that are making
a huge pollution when its produce energy, and they are going to finish soon, so, we should have some other power to substitute with its.
3. It can be make very large quantities of ash have to be disposed of a lot of smoke is produced, although in mordern power stations most of this is separated from the waste gas stream and disposed of with the ash. Antway I mean, that coal gas is not good at pollution.
jack
1may be yes bcause it can be used again and again and recycle that
2water power plant can do that
3 I don't like it because if we finish the coal ,it can grow again ,

.Because the energy still have the bad things too,like
the coal will produces more co2 per watt-hour of energy than ang other gerenation method.\
by alex
1.may be, it's good. because it's converted to electricity about creating megawatt hours per year.
it will make the plant welf-sufficient.
2. wind is other forms of energy. Now, we can use wind to make electricity power. example, the wind power makes electricity. the wind power's fence going aroudthe wind power. so it makes powers.
3. Coal has an unfait advantage power generation.
a coal-firled power station generates a large amount of energy. It's renewable methods. coal does not have any space advantage over several nethods. It's burn coal without producing carbon dioxide.
1.Do you think this is a good idea...and if so why...if
not why not...
I think it 's very wonderful and useful idea!
Nobody couldn't think about using dirty water to
produce electricity.
2.What other forms of energy could we use to produce power (i.e. electricity) instead of using coal?
Nowadays, we can produce energy by a lot of
method. Such as using sunshine,using wind power,biomass and so on. But I think biomass
is better than any other energy industries.
It's similar with sewerage energy producing.
It's use wastes of animals or plants.
3.
Actually, coal has been used since industrial revolution, and because of coal industry, environment had been polluted.
Do you think this is a go od idea... and if so why... if not why not...
I really think this a good idea. Because I think the coal is become less and less and other form of energy are also became less and less now. We need to find some new way to get energy. this is a new way, and it produce less pollute.
What other forms of energy could we use to produce power (i.e. electricity) inst ead of using coal?
Naturl gas, petroleum, high place’s water, wind, sun shine, sea. living thing(plant,animals),
What is wrong with using coal power to produce energy? ... If you can't answer this question off the top of your head do an Internet search to get your answer. If you type in something like "coal powered electricity pros and cons" into Google you'll find plenty of sites to look at.
Using coal will produce a lot of carbon dioxide and sulphur dioxide, these thing will make our earth become warmer and warmwe,and they can distory the atmosphere.

1. I think it is good idea, because it is kind of recycle and good for the earth.
2. Heat, water power, wind power, solar power and atomic power.
3. I think because caol is not permanent resource, so we can't use it forever. And coal produces more CO2 which is the coase of the global waeming, so it is not good.
