Alternative energy sources
Alternative energy sources
Hydroelectric
Power from moving water
Two ways,dam or river
Cost competitive,reliable,flood control, and base-load power
Impact on wildlife
Dam could fail and cause a flood
Clean energy, No CO2 output
Plants release methane
Geothermal
Uses natural heat from the earth
Energy drawn from earth using water and steam
Hot water pumped from earth used to heat homes and buildings
Up front is more expensive but, Reliable and consistent power source
Releases CO2 and hydrogen sulfide
Can lower ground temp.
Most effective in areas with volcanic activity
Biomass
Energy produced by plants
Combustion (small fire (heat) )
Fire can be used to heat steam producing energy
Gasification
Renewable energy
Used in fuels, or bio-oils
Uses anaerobic digestion to breakdown organic matter into fuels and power sources
Wind
Different speeds due to location, season, and the surrounding structures
Power generated from moving wind
Clean energy, No CO2 emission
Not always blowing
Cost more than traditional
energy resources
Noise,birds, land availablibility are disadvantages
Solar
Most Available renewable Energy
Clean energy, not harmful to environment
Thermal energy from the sun
