Why
do we need to conserve energy?
Everyone scare
of global warming. Someone said Global warming can be slowed down, and stopped when we
conserve energy. But why we need to save energy and how energy is relates to
global warming? I will give you the answers in this essay below. So, let’s
start now!
First we
should know ‘What is energy?’ Energy is the source usable power. We often use
energy to create new technology. Energy sources can be divided into two groups,
renewable and nonrenewable. Renewable energy sources include; solar energy
(from the Sun), wind energy, hydropower energy ( from water) and geothermal
energy (from heat inside the earth). Nonrenewable energy source are; fossil
fuels — oil, natural gas, and coal. (These sources came
from fossil) which stay underground the Earth for millions
and millions years. Another kind of nonrenewable energy source is Uranium
(element). We use both of energy sources to generate the electricity in our house,
office, schools, and factories. Gasoline and Natural gas (most of us use for
cooking) are made from nonrenewable energy source.

See? Most of
energy comes from natural resources. When we burn these resources it create
carbon diovide which generate air pollution. Actually air pollution always
bring toxic that not good for our body, it causes cancer. The worst thing that
could happen when we burn too much natural resource is “Global Warming”. Energy production is so harmful to the environment. What
we can do is save energy for reducing such harm and save our world. This
is the first reason why we should conserve the energy. There is a limitation of
nonrenewable energy sources. Because one day, the mines will be empty and drilling
pipes will be dry out.
If we don’t have
energy what will happen? All forms of transportation like cars to airplane use
energy. And because of this, I can tell you that energy is a part of
civilization. Without transportation, trade is impossible. Also we need energy
(Electrical) generate electricity. If we don’t have energy, we will not be able
to use electricity. We must be in trouble.

So, how can we
conserve energy? There are many sources on website that give us ideas for what
can we do to save energy. Here are a few ideas. Change your travel behavior,
use public transportation. If your destination isn’t too far, you may walk or
ride a bicycle instead. Adjust your habit, such as turning off lights and electrical
appliances when you are not using them. You can also use energy-saving light bulbs.

When you save
energy you not only save your money but you also reduce the demand of nonrenewable
resources such as fossil fuel. What kind of world do we want to leave to our
children’s children? If we continue to use energy at our present rate, all oil
and natural gas will be gone. How
hard life is when world don’t have any energy?
