About Geothermal Energy
by Kyle Bryant and Sèan Reeser
• Geothermal energy
uses the heat from
below the Earth’s
crust.
• Some examples of
natural geothermal
energy on the planet’s
surface are geysers
and natural hot
springs.
Tapping into Geothermal Energy
• To tap into geothermal energy, pumps draw heat
from the Earth or underground water sources.
• Certain systems can also obtain geothermal
energy from liquid magma.
• In order to reach depths at which geothermal
energy is accessible, rotary drilling has always
been used in the past.
• Recently, a thermal drill has been developed that
uses heat to reach geothermal heat sources.
This method is much more efficient, more cost
effective, and can dig deeper than rotary drilling.
Uses of Geothermal Energy
• Heating pumps that draw heat from the
Earth use that heat to help heat and cool
buildings.
• Some facilities use the heat from
geothermal energy to generate electricity,
which is supplied to businesses and
homes in the surrounding areas.
