1. Geothermal Energy
Created by Corey Boisvert

2. This form of renewable energy
comes from the Earths core. It
produces thermal energy from
regions that have temperature
extremes such as volcanically
active regions, steam beds or
hot springs. Geothermal energy
is considered one of the best
sustainable energy sources
because it is natural and
available in most places

3. Convenience is the best!
• It is very easy for the
average homeowner to
invest in Geothermal
Energy because it drills
down from most areas
on the earth’s surface
to the core then
converts dry steam to
electricity.
• When a homeowner
invests in this product,
costs on electricity go
down as opposed to
purchasing fossil fuels,
also leading to less
global warming.
The diagram above shows two lines out and in of the
house, the blue is the dry steam gained from the part
underground while the orange is the cooled water that
is returned to the ground.

4. Cost of running
• Despite the helpful
impact power plants
have on the
environment, cost is high
and the work is risky.
• It can cost the
government an average
of $10 million to build a
power plant (Or drilling)
and has only a 80%
success rate of
retracting magma from
the earth’s crust.
• It has about a capitol
cost of $4 million per
year to run the power
plant.

5. Seeking heat under Bow:
“Take down the Fossil Fools!”
• Officials have agreed to begin construction of a Geothermal
Energy Plant in Bow, NH. The project is underway currently
and recently started after a few Massachusetts scientists
agreed that the geological factors in Bow could have magma
levels high enough to make a drill. Atlantic Geothermal LLC is
responsible for the production and the capitol cost is believed
to be around $786 million due to extensive digging. If plant is
successful it could produce up to 330 megawatt.

show
support
for the
construction
of the plant

6. Economics
Geothermal heat
pumps save money.
Schools now using
geothermal heat pump
systems save more
than $25 million in
energy costs - meaning
more money for books,
equipment and
teachers. Homeowners
can save 25 to 50
percent on home
electric bills compared
to conventional heating
and cooling systems.
Electric bills for a 2,000
sq. ft. home can be
reduced to as low as
$1 a day, using a geo-
exchange system.
The chart above shows how much the average
NH 2,000 square foot home owner pays for
heating and what they could pay with other
alternatives such as geothermal sources
Non-hydroelectric Renewable Generation
has about an average cost of 87 Billion Kilowatt

7. Pros and cons
PROS
An EPA study of energy efficiency
concluded geothermal energy is the
most environmentally friendly
heating/cooling system.
The United States National
Renewable Energy Laboratory
concluded that geothermal energy
is more efficient and cost-
effective compared with
conventional residential
systems.
Available everywhere in the
United States, geothermal
energy can be found
underground virtually
anywhere.
Geothermal cost savings can
be increased by geothermal
energy incentives, available
from federal, state, local, and
utility sources
• CONS
• Geothermal Energy is very costly, and
there for not available to some US
citizens
• Geothermal Energy pumps are
useful, but only gradually. The
buyer pays a lot of money for
his/her product and only
gradually makes the money back by
less money on electricity
• Geothermal Energy can lead
to the leaking of gasses
from underground wells into
the earths atmosphere
leading to addition of
greenhouse gasses in global
warming.
• Geothermal energy only
makes up about .37% of the
US energy sources, as
opposed to in Iceland, where
it makes up about 30%

I made this chart
myself!

9. Contribution to ‘GW’
Though Geothermal
Energy is a minor
energy source in the
world, it still
contributes to Global
Warming. When drills
are set into the
ground they emit
gasses from under
the earths crust into
the atmosphere that
are potentially
hazardous to the
ozone layer.
Though most of the emissions in these pictures are steam, some can be harmful chemicals.

10. Relationship to
conservation of energy
• The law of conservation of energy states that “Energy can
neither be created nor destroyed, but converted from one form to
another”
This concept applies to Geothermal Energy because the
harvested dry steam and thermal heat from the magma in the
earth’s core is thermal energy, this is then transferred to a
cooling or condensation tower, which turns the water vapour
left cool enough to be returned back into the earth’s surface.
The steam is converted from thermal energy into heat or
possibly electricity.

11. Pleas for exploration into
Geothermal Energy Plant
• Plans in Adelade, Australia.
• Despite the promising
chance to cut back on
burning of fossil fuels in
Australia, officials are not as
excited for this new chance
at exploration as comparison
to in Europe. Officials are
leaning more towards not
approving the operation.
"Finding the resource; that's
the main risk in our
industry. So we argue that
the government should be
contributing to the risk of
finding the resource," Says
Susan Jeans (Founder of
AGEA)

12. Fun Facts
• About 10.000 years ago, Paleo-Indians used hot
springs in North America for cooking. Areas around
hot springs were neutral zones. Warriors of fighting
tribes would bathe together in peace.
• There are over 140 schools and over 10,000 homes
with geothermal heat pump systems in Texas.
• The hottest Geothermal well recorded is 510°F @
23,800 ft (-96.86 Longitude, 28.79 Latitude) east of
Victoria, Texas
