Alternative Energy Sources
Geothermal
Geothermal power plants can convert geothermal heat into electricity. The steam turns turbines on a generator which converts the steam to electricity
Can release harmful gases into the atmosphere, and can lower ground temperatures
Wells are 3-10 km in depth
Use water and stream to extract heat from earths core
Depletes the water table
Upfront cost is more expensive because of testing and ground analysis but it is an efficient sou cue of energy if it can Be used
Heat from the earths core
The hot water can directly heat the home by running through pipes in the home, or go through a heat exchanger (out buildings that transfers heat to the building
Very reliable and consistent production of energy
Most effective in areas of active volcanic activity
Solar
Clean energy, not bad for environment
Sometimes not available, night time , winter, etc
COST???
Most available renewable energy
Thermal Energy from the sun
Solar PV Panels convert light to electrical energy
Converts light and or thermal energy into electrical energy
Biomass
Organic matter burned to produce heat or energy in the place of fossil fuels
Renewable
Used for fuels,or bio-oils
Uses anaerobic digestion to breakdown organic matter into fuels and power sources
Made from organic matter like plants, trees, waste
Can be sourced locally and help support the local economy
Wind
Clean energy,
NO CO2 emmision
Converts Kinetic Energy (moving wind) into mechanical energy (turbine) to electrical energy
Can affect migratory bird patterns
Different Speeds due to Location,Season and the surrounding structures
Not always blowing
Noise, birds, land availability are disadvantages
Cost more than traditional energy sources
Power generated from moving wind
Cost decreasing
Hydroelectricity
Helps with flood control and water supply
Produced using turbines and generators
Dams have more controlled energy production
Cost competitive
Power from moving water
MOST used for public energy production
Negative impact on fish habitat
Dams and Run of river
Kinetic energy(moving wate)t mechanical energy(turbines)converted to electricity energy(in generator)
