Alternative Energy Source
Geothermal
Producing energy from the internal heat of earth
Used to produce electricity
Reliable and consistent
Expensive;Seismic sensing, Test Well Drilling, & Confirmation Testing
Wind
Different Speeds due to
location , season, and
the surrounding structures
Power generated from moving wind
cost more than traditional energy sources
Cost is decreasing
Clean energy,NO CO2 emission
Noise, birds, land availability are disadvantages
Solar
Most available renewable energy
Thermal energy from the sun
Solar PV Panels convert light to electrical energy
Clean energy, not bad for environment
Not always available in winter time, or & night or dawn
Hydroelectricity
Power from moving water
Produced using
turbines and generators
Dams and a Run of River
Dams have more
controlled energy production
Most used for
public energy production
Cost competitive
Reliable
Helps with flood control and water supply
Negative impact on fish
habitat
People may have to move
from riverside home
Not fully clean, creates CO2
Biomass
Produced from organic matter
The processes
combustion, Gasification, Pyrolysis, Anaerobic Digestion or Biodigeation, & Fermentation
Makes up a small percentage of worlds use
For approximately 2.5 billion people, it remains
the primary source of energy for cooking and heating
Availability of resources, availability of technology and economic availability are all drivers of biomass use.
The environmental benefits and cost are highly contextual depending on the technology and feedstocks used
