Alternative energy source that use the natural power of the wind, waves and sun are too expensive and complicated to replace the coal, oil and gas that we use to power our cities and transport. To what extent do you agree or disagree with this opinion.

Sustainability is one of the most popular discussion topics, which everyone from all over the world needs to pay attention to. There is no shortage of a debate on whether it is too complicated and costly to replace fossil fuels with eco-friendly

resources

, but I believe that sustainable

energy

resources

bring more benefits than the expenditure they cost in a long run. I feel

this

way for two reasons, which I will explore in the following essay.

Firstly

, replacing the

energy

sources with sustainable

resources

is not too complicated, compared with the situation where we ought to think about the solution to the adverse effects of keeping burning fossil fuels.

For instance

, it's usually said that carbon emission causes global warming over the world, which is even getting serious nowadays. In order to make an appropriate action and deal with

this

issue, all the governments need to discuss, enter into an agreement and cooperate, which is extremely arduous and troublesome.

Hence

, establishing new plants, e.g. a solar panel and a hydroelectric plant is by far more feasible.

Secondly

, when we discuss cost, both monetary and non-monetary impacts have to be taken into account.

For example

, if we keep deforesting in order to supply fossil fuel, residences of wild animals will be devastated completely, and the wild animals will extinct in the end.

Although

it is difficult to evaluate the monetary value of

such

wild animals, we need to clearly understand that

extinction is a cost we need to pay.

Consequently

To summarize, shifting to sustainable

resources

is not too complicated if we imagine the required efforts to solve the future problems and to keep utilizing fossil fuels is much more expensive, taking into account all of the sacrifices. It is

therefore

clear that the statement does not hold water at all. After a thorough analysis

subject, it is predicted that the positive effects of the replacement of the existing

resources

with the new

will always be greater than the adverse effects, and because of

this

, I strongly suggest that all the countries make their best efforts to substitute the

energy

resources

as soon as possible.
