Renewable resources of energy (sun ,wind, water) will soon replace resources of fossil fuels(gas ,oil and coal ) ,agree or disagree

Our environment is being devastated by fossil fuels we emit everyday,scientists together with governments have already began to propose renewable resources as substituents, because they are pollution free and hard to depleted.However,when consider practical meaning ,we may not put much hope into this because renewable reources will not replace fossil fuels very soon.

One of the reasons is the expensive price of using renewable resources.By bringing such energe into practical use rather than experiments in the lab,a substantial amount of money has to be spent to build infrastructures.We have to build thousands of solar panles ,wind farms,water tubines and it is really costly.Also,the fact is that we need more money to do research in this field  to solve the problems we face in the process of using them,like repair of infrastrctures.The result is that only few people can enjoy such service ,most people cannot afford and they will not be willing to pay for .Only if we lower the cost of such renewable resources,or it can not replace the cheap fossil fuels .

Another reason is that  the technology of using such resourses itself  is not mature enough.Many experiments succeed but that dosen't mean it will work in practical life.I noticed a news report on the website SCIENTIFiC AMERICAN,thousands of solar farms will be built, called a solar grand plan,it is the most practical thing in this field and it is still having many problems-They cant provide energe at night.It is terrible when wind turbines stop working and solar palnes are broken,in that way,we have nothing to heat the building or light the office. In this case,people will still choose those reliable resourses like fossil fuels because they seldom disturb normal life.

It is true that renewable resourses do no harm to the environment ,however,it is still not as convenient and inexpensive as fossil fuels.It will be a long way when  renewable resourses compeletly come into our life.

总的来说挺好的

说几个文章结构的问题：

两条理由有点少了，而且最好加一个反面的理由，也正好补补字数，显得文章更充实。

另外美国人是直线式的思维，所以最好在第一段明确的表明观点。

Our environment is being devastated by fossil fuels we emit everyday (Delete this, because it is not fossil fuel itself who devastates our environment, but its waste gas),scientists together with governments(unbalanced parallel->scientists and politicians) have already began to propose renewable resources as substituents (begun to seek other renewable energy forms as replacements),
        because they are pollution free and hard to deplete(don't shift the subject from 'human' to 'they', which in this case are fuels. for the sake of environmental suitability and sustainability).However,when consider(ing) practical meaning ,we may not put much hope(many hopes) into this because renewable reources will not replace fossil fuels very soon.(this is also an unbalanced structure->the writer has two reasons, practical meaning and 'because' clause, however, instead of well organizing them by paralleling, the writer put one in the front and the other in the rear, which may seriously affect its structural integrity)(However, we may not put many hopes into this, not only because renewable reources will not replace fossil fuels completely, but the renewable resources are not practically usable until now)

One of the reasons is(shorter is better, Firstly,) the expensive price(expensiveness) of using renewable resources may prevent people from implementation.By bringing such energe into practical use rather than experiments(from experimental trials) in the lab,a substantial amount of money has to be spent to build infrastructures.We(Don't shift the subject from 'things' to 'human', which in this case is 'we') have to build thousands of solar panles ,wind farms,water tubines and it is really costly.Also,the fact is that we need more money to do research in this field  to solve the problems we face in the process of using them,like repair of infrastrctures(keep consistency of the subject).The result is that only few people can enjoy such service ,most people cannot afford and they will not be willing to pay for .Only if we lower the cost of such renewable resources,or it can not(a reversion is needed, like 'can it') replace the cheap fossil fuels .

it is true that renewable resourses do no harm(good) to the environment ,however,it(they are) is still not as convenient and inexpensive(unbalanced parallel->convenient and affordable) as fossil fuels.It will be a long way when  renewable resourses compeletly come into our life.
