Energy Resources
Introduction of the different types
Classifications of Energy
Non-renewable vs. Renewable (click links for video)
Non-renewable: Energy source which cannot be reused

Renewable: Energy source which can be reused but may have limitations

Non-renewable
Fossil Fuels: Type Definition Pros Cons
Coal Combustible rock used to heat
-cheap-abundant -continuous power
-carbon dioxide/methane -global warming-severe safety impacts
Natural gas A hydrocarbon gas, methane, that is naturally found
-widely used around world-cleanest fossil fuel-no waste
-explosive-80-95% methane-store under high pressure
Nuclear Power Plant Splits uranium ore through fission process to provide electricity
-large energy output-small amount ore needed-low carbon dioxide and greenhouse gas release
-nuclear meltdowns-release radiation-waste storage problems
RenewableType Definition Pros Cons
Solar Radiant/heat energy from the sun- need solar panels
-near 0 operating costs-high efficiency-no pollution
-sun limitations-need backup source-intermittent
Geothermal Energy coming from and stored in the Earth
-near emission free-no fuel required-smallest land footprint of energy supplies
-prime location specific/far from population centers-need >350 oF temperature-high construction costs
Biomass Energy from organic material or trash that is burned
-naturally distributed-abundant supply-convert waste to energy
-deforestation-pollution when burned-compete with food growth
Wind Energy from the wind- need wind turbines
-low cost-very clean-free power after install
-limited wind-large turbine space-wildlife impact
Locations
Where the various types are found and used
The following link is from GE electric companies from 2010 statistics based on the top using countries for the various sources and the amounts used http://www.gereports.com/a-good-look-at-renewable-energy-around-the-world/
The United States ranked 1st in use for Geothermal and Biomass energy, and 2nd for solar and wind
Costs
Costs to install or use energy sources
Biomass: free- uses trash and wastes
Solar- from $15 -20,000 for average sized house
Geothermal- ~$18,000 for pump and installation
Wind- 10kW turbine ~ $35-50,000/per turbine
