Long Essay on Renewable Energy (500 - 600 Words)
Introduction
Energy can be renewable or non-renewable. Renewable energy can be
renewed or re-generated easily but the non-renewable resources are limited
on the earth. They can’t be generated again. Therefore, renewable energy is
much better than non-renewable energy.
Sources of Renewable Energy
There are five major sources responsible for generating renewable energy.
They are:
Solar energy: Sun is the major source of renewable energy that is
termed as solar energy. The light and heat of the sun are used to
produce energy. Solar cookers, solar panels, or solar cells are used to
utilize solar energy. Scientists are also preparing to launch solar-
powered cars.
Wind energy: Wind is also used to produce energy. Windmills run
using turbines and generators are constructed to generate wind energy.
Wind energy is a good contributor to global energy demand.
Biomass energy: Wastes from plants and animals are used to produce
energy, which we call biomass energy. Biomass is an eco-friendly
method of energy production. Different methods are used to produce
biomass energy from biofuels.
Geothermal energy: Geothermal energy is produced from the heat
below the earth’s surface. This energy can be used to produce
electricity, heat buildings, bathing, etc.
Hydropower energy: The force of water is used to produce energy and
is referred to as hydropower energy. Hydropower is more reliable
than other renewable sources. The construction of reservoirs, canals,
dams, etc helps to control the flow of water which is later, used to run
turbines to produce electricity.
Advantages of Renewable Energy
The primary advantage of renewable energy is that it can be renewed
easily. It is the only option that will meet the energy requirement of
today as well as tomorrow. Unlike fossil fuels that are limited on the
earth, we can use renewable energy for a lifetime. Renewable energy is
good for both humans and the environment. Non-renewable energy like
fossil fuels causes pollution and environmental hazards like acid rain,
global warming, etc. The amount of carbon emissions from renewable
energy is much low than those of non-renewable energy.
Therefore, depending on renewable energy will save us from this
serious issue. Renewable energy is the most reliable form of energy and
we can also say that it is the future of the world’s energy needs.
Disadvantages of Renewable Energy
The main disadvantage is the cost. The cost of generating energy from
renewable resources is very high when compared to that of non-
renewable sources. People find burning coal cheaper and easier than
installing a solar panel.
Most of the renewable resources depend on natural sources that can
be obtained in a particular location. For example, solar energy cannot
be fruitful for cold locations or hydropower energy can only be obtained
in a location where fast-flowing water resources are available. The
hydroelectricity project has an adverse effect on aquatic life and
the ecosystem.
Conclusion
The increasing population demands an increase in energy consumption.
Energy is necessary for home, business, and almost every work. Thanks
to innovation and invention that helps in utilizing renewable
resources and maintaining a sustainable level of energy in the world.
