Fossil fuel (e.g. coal, oil and gas) are the main source of energy for most countries. However, alternative sources of energy (e.g. wind and solar) have been encouraged for use by some countries. Is this a positive or negative development?

Despite the fact that fossil fuel is still mainly consumed by a majority of nations nowadays as a critical source of

energy

, some countries start to promote alternative energies in order to protect the

environment

and advance humans. I consider

this

mainly positive as the study of other forms of

energy

helps protect the

environment

and promotes worldwide peace among numerous countries. Admittedly, the advancement in

energy

alternatives could be quite costly, requiring a large amount of capital and human resources for scientific research. Governments with tight budgets that try to simultaneously fund several social welfare programs may/might find it challenging to absorb

this

additional cost.

Besides

, it is hard to estimate the payback period for developing “green

energy

”, as no one knows exactly how long it will take for engineers to come up with feasible ways to utilize clean

energy

,

such

as wind and solar on a large scale.

However

, the use of alternative

energy

plays a vital role in preserving natural resources and protecting the

environment

. As we all know, fossil fuels,

for instance

, coal and oil, are often non-renewable and the excessive exploitation of fuel resources has led to serious consequences on the local

environment

.

For example

, countless forests have been removed by greedy merchants in order to drill for oil, making the issue of global warming even worse in the long run. Humans are making their

first

efforts to develop environmentally acceptable solutions to the

energy

crisis by researching substitutes for reusable

energy

.

Furthermore

, pursuing “green

energy

” can greatly promote worldwide peace, as fossil fuel will no longer serve as the single source of power that every country aggressively competes for. We can certainly expect that if every nation is capable of supplying itself with sufficient, renewable sources of power, there will be significantly fewer intentions for wars. In conclusion, while the bill for developing alternative sources of power might be quite high, I still insist that it will be beneficial not only to the

environment

but

also

to global peace.
