| back 1 Points Of This Presentation (If You Listen Closely):
- Chemistry/Climate Change
- How Geothermal Energy
Works
- It’s pros and cons
- Technology
- Google Slides is the inferior presentation software to
keynote
|
| back 2 Law of Conservation of Energy: Energy can not be created or
destroyed, only converted.
Understanding this helps us create better systems to harness
renewable energy.
- Limitations of different technologies and processes
The most common energy transformation for most energy resources is electricity |
front 3 The Relationship Between Energy and Humans | back 3 What effect does using energy have on citizens' lives
- Residential: Heating, Lighting, Running water, Powering
devices
- Transportation
|
front 4 Energy Sources (renewable vs non-renewable) | back 4 Similarities: Perform the same functions
Renewable: Replenishes naturally
Non-Renewable: Causes more pollution, will eventually run out |
front 5 Energy Conservation vs Energy efficiency | back 5 Energy Conservation: Changing habits to use less energy
- Unplugging laptop when not using it
- Unplug TV when
you go on vacation
- Only wash full loads of laundry and
dishes
Energy efficiency: Using technology to reduce energy use while
performing the same task
- LED Light Bulbs
- Use an internal combustion engine in
your car
- Using Hybrid Cars
In what ways does energy impact the environment?
- Causes pollution and climate change

front 6 Geothermal Energy Systems | back 6 Heat is extracted from the Earth
- A geothermal system typically involves drilling deep into the
ground to access the hot water and steam that is naturally produced
by the Earth's core.
Heat is converted into usable energy
- The heat extracted from the ground is then used to power a
turbine, which generates electricity or can be used to provide heat
directly.
Heat is re-injected into the Earth
- Once the heat has been extracted, it is important to replenish
the heat source in order to maintain the long-term viability of the
geothermal system. This is typically done by re-injecting the cooled
water or steam back into the Earth's core.

| back 7 +
- Reliable
- Not dependent on the elements
- A geothermal power plant could last for 50 years
- Power plant requires ⅙ the amount of space of a solar power
plant
-
- Initial investment is expensive
- Geothermal
drilling can increase the number of earthquake
How much does it cost?
- $2,500 per installed kW, compared to about $1,600 per
kW for wind turbines
- Compare it to other non-renewable energy sources.
- Does not burn fuel to
generate electricity
- How is it
similar?
- How is it different?
- Compare it to
other renewable energy sources.
- More environmentally
friendly but less efficient than fossil fuels

front 8 Geothermal Energy usage in the United States | back 8 3,714 MW - 2020
4 plants in USA
NY is not a good location
- Not subject to tectonic plate movements
- No
volcano activity
- New England is better
- Vermont, New Hampshire, and Maine have favorable geological
conditions for geothermal energy production. These states include
significant volcanic and geothermal activity from past geological
history. This provides a better potential for harnessing
geothermal energy.
