Transcript of Can alternative energy effectively replace fossil fuels?

What is Alternative Energy?
Energy generated in ways that do not deplete natural resources or harm the environment
Are renewable/sustainable and thought to be "free" energy sources.
Biomass energy, Wind energy, Solar energy, Geothermal Energy, Hydroelectric energy.
What are fossil fuels?
A natural fuel such as coal or gas
Formed in the geological past from the remains of living organisms
Fossil fuels: Pros
Mature Commodity that requires no new technology or research.
Easy transportation to all locations and easily converted to solid, liquid, or gas.
Creates millions of jobs. (mining, transportation, production.)
Creates incredibly useful byproduct (plastic)
Wind Energy
Wind power is the conversion of energy into a useful form of energy, such as using wind turbines to produce electrical power, windmills for mechanical power, windpumps for water pumping or drainage, or sails to propel ships.

"Don't say 'wind farm'. I'm already feeling gassy."
- Tony Stark
Wind: Pros & Cons
Pros:
Green
Enormous Potential
Renewable
Space Efficient
Rapid Growth
Prices are Decreasing
Lower Operational Cost
Good Domestic Potential
Solar Energy
Radiant energy emitted by sun
Solar Power: power obtained by harnessing the sun's rays



Solar: Pros & Cons
Pros:
Renewable
Abundant
Sustainable
Environmentally Friendly
Good Availability
Reduces Electricity Cost
Many Applications
Shared Solar
Silent
Low Maintenance
Financial Support
Technology is Improving
Geothermal Energy
Heat energy from the earth
Sources: hot water below the earths surface to Magma
Works off of a geothermal heat pump
Very small environmental foot print
GOAL!
Can alternative energy effectively replace fossil fuels?
Presented by: Brianna Jacobson, Joe Hanson, Sam Haberland, Anna Schmit, & Mike Hershberger
Geothermal: Pros & Cons
Fossil Fuels: Cons
Not green - High levels of carbon dioxide
Non-renewable - finite supply
Extremely dangerous to excavate
Harmful to environment & human health
Coal/oil liquid run-off pollutes water supply above/below ground
Byproducts of fossil fuel production are highly toxic
Cons:
Expensive
Intermittent
Energy Storage is Expensive
Associated With Pollution
Exotic Materials
Requires Space
Pros:
Geothermal is non-polluting, and sources are naturally refilling
Huge Potential
Massive heating/cooling benefits
Already in use in a huge portion of the world

Cons:
In extreme cases, earthquakes can be caused
Heavy upfront costs
Location specific

Cons:
Unpredictable
Costs
Threat to Wildlife
Noise
Looks
Looking into the FUTURE

If change does not happen soon:
32% Coal
35% Natural Gas
16% Nuclear
16% Renewable

Conclusion
We need a change in mentality, first at a local level. Lifestyle changes are needed to cater to what nature imposes.
Once change is implemented, it will get the ball rolling for a national push towards alternative energy.
Automotive companies need incentive to break away from oil and instead create exclusively electric/alternatively powered cars.
