Energy in our
Society
Our society consumes
a lot of energy. We use energy to
travel, heat and cool our homes, and to make and transport products. But, using energy creates problems.
Two main types of energy are used in everyday life: Electrical Energy and Combustible (Fuel) Energy. Electrical energy is used in homes, industry
and transportation. Combustible or Fuel
energy like, petrol, diesel fuel and
natural gas are used in transportation
heating and industry.
Using energy creates problems like depletion of resources and pollution.
Pollution leads to global
warming, acid rain and contamination
of our air, land and water.
Fossil Fuels are
a non-renewable source of
energy. So, if we use them, they will
eventually run out. We rely so much on fossil fuels that it
is difficult to use only renewable
sources of energy. Governments must promote the use of renewable sources of energy like solar and wind power. Scientists are trying to find ways of making
renewable energy cheaper and more efficient.
Radioactive
Waste is a special type of pollution. It is produced in nuclear power plants. It gives off radiation that is deadly to
all living things. Scientists are still
not sure the best way to dispose of
this type of waste.
