Fossil fuel, such as coal, oil and natural gas, is extensively used in many countries which cause harms to the environment. The use of alternative sources of energy, including wind and solar power, however, is being encouraged in many countries. Is this a positive or negative development?

In the recent years, many of the developed and developing countries are encouraging the use of solar and

wind

power

instead

of coal and oil fuels. There are numerous reasons for

this

shift and

this

enhancement

also

has pros and cons which will be cited in the essay below.

To begin

with, in the

last

few decades, there has been an upward trend in the number of industries due to industrialization across the globe, which has led to the increase in the use of oil, coal and other fossil fuels.

This

in turn has led to increase in the

air

and water pollution in many countries.

Therefore

, many nations are opting for substitutes of these resources which will not add to global warming. There are many benefits of using solar and

wind

energy

which includes being cost effective, less pollution, reduction in usage of other resources and so on and so forth. Solar

energy

does not produce

air

and water pollution,

hence

, gives cleaner

air

to breathe. Usage of solar

energy

also

is one of the prime factors which helps in reducing the electricity bills.

On the other hand

, there are a number of advantages of using wing

energy

as it is free of cost, unlimited, low maintenance. Unlike other types of power plants, it emits no

air

pollutants or greenhouse gases. The

wind

turbines harmlessly generate electricity from

wind

passing by.

Wind

energy

is far more eco-

friendly

Suggestion

more friendly

friendlier

than the burning of fossil fuels for electricity.

Also

,

wind

turbines can generate

energy

24 hours a day since they are not dependent on sunlight. To conclude, it is evident that using solar and

wind

power has more positive impact and

hence

, they are encouraged by many nations.
