1. SUMMARY ON ENERGY FROM FOSSIL FUELS,
GEOTHERMAL AND HYDROELECTRIC POWER
PLANTS

2. • Energy from fossil fuels, geothermal, and hydroelectric power
plants enables people to operate machines. From big factories to
small households, these energy sources help us in accomplishing
tasks that make our lives easier. However, we must be aware
that the use of these sources of energy comes with
consequences that must be addressed.
• The use of fossil fuels poses a great impact in our environment
including enhanced greenhouse effect, air pollution, acid rain,
and changes in the natural features of the land. Reducing the
energy consumption produced by using fossil fuels is one way to
address these concerns.

3. • Energy conservation is decreasing one’s consumption of energy which
helps lessen the need for burning fossil fuels. You can decrease your
energy consumption by turning off appliances when not in use and
limiting the use of appliances.

• Energy efficiency is the use of less energy but still providing the same
output desired. One example of this is the use of LED lights which require
less energy but provide the same desired output as incandescent and
fluorescent bulbs. Energy efficient cars and aircrafts are also designed and
produced by manufacturers wherein modifications on its design, from its
physical appearance to its engine, require less energy but provide the
same service.

5. • Renewable sources of energy, also called as “clean sources of energy”,
help lessen the effects of fossil fuel use. Unlike fossil fuels, geothermal
and hydroelectric power plants emit less air pollutants. However, the
construction of these power plants changes the natural features of the
land and may affect the living organisms that live within that area. An
environmental impact assessment of building the structures and
operating the power plants can help authorities properly plan the
construction and prepare appropriate measures that will lessen the
negative impacts.
• If the demand for energy is reduced, the power plants will lessen their
production of electricity, and the construction of additional power plants
will not be needed. Awareness to ways of energy conservation and energy
efficiency also plays a vital role in addressing these concerns.
