Alternative energy resources 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 power our cities and transport.

Some people say that getting

from coal, oil and gas which is used to light up towns. In my point of view, it is true enough that retrieving

energy

from the sun,

wind

and wave needs a

lot

of various methods, but the cost may be lesser as compared to using oil or gas because the

is not an easy job and it required a

In addition

so it is usually built in rural regions.

On the other hand

from coal, oils and gas is easy because we just need people and machines to drill to get resources and it is so simple as compared to use the natural resources.

However

In addition

, there may be less oils or gas production in near future because of shortage of resources and they may run out one day.

For instance

therefore
