Fossil fuels are the main source of energy around the world. However, people are being encouraged to use alternative energy sources such as wind energy, solar energy and so on. Do you think this is a positive or negative development? Why?

Fossil fuels are the primary
energy
source around the globe. Yet, people are being asked to shift towards the utilization of
alternative
energy
sources
,
such
as wind and solar
energy
. The use of
alternative
energy
sources
has a positive effect because fossil fuels may be dearth in the upcoming years.
However
, there is still a problem regarding the price-to-efficiency ratio of
alternative
power
source usage. I personally agree with the latter statement
due to
the economic disadvantage renewable
energy
power
sources
have. Fossil fuels are made from non-renewable resources,
such
as coal, which may not be as abundant as it is now in the future. It takes thousands of years to produce the raw materials by natural process. We can see clearly now in Indonesia that fossil fuel prices have been rising significantly over the
last
decade, indicating a limited amount of supply available. If fossil fuel consumption does not decrease, humans may not have enough stock of resources for the centuries ahead.
On the contrary
, the output efficiency that
alternative
power
generators provide is not high compared to its expensive cost. The use of renewable
energy
sources
may be very expensive to install, run, and maintain.
For instance
, solar cell panels can only absorb less than a quarter of the
energy
provided by the sunlight. The fact that the equipment is very expensive to install, adds a reason why solar cell
power
plants are unfavorable compared to coal-based
power
plants.
To conclude
, humans may need an
alternative
energy
source because non-renewable resources are limited in supply.
However
, the cost to operate a renewable
power
plant is still very expensive, considering the low output efficiency.
