alternative energy sources
alternative energy sources
hydroelectric
dams have more controlled energy production
negative habit
not bad for environment
helps with flood control and water supply
dams and run of water
produced using turbines and generators
solar
biggest supply of solar energyy
sometimes not available in,night time,winter, etc.
clean energy not bad for the environment
thermal energy from the sun
solar pv panels convert light to electrical energy
cost??????
wind
different speeds due to location season and the surrounding structures
power generated from moving wind
clean energy,NO CO2 emmission
the wind is not always blowing
the cost is more then traditional energy source
noise,birds and land availability are a disadvantage
geothermal
use water and stream to extract heat from earths core
upfront cost is more expensive because of all the testing and ground analysis but it is efficient source of energy if it can be used
most effective in areas of active volcanic activity
heat from the earths core
depletes the water table
biomass
made from organic matter like plants,trees,waste
uses anaerobic digestion to breakdown organic matter into fuels and power sources
used for fuels, or bio-oils
renewable
