Energy Sources
http://www.thermopolis.fi/main.htm
Renewable Resources:
1. Geothermal- heating and cooling using water
- industrial and agricultural heating processes
2. Biomass fuels
- organic materials such as plant matter and biomass waste (wood, compost pile, municipal solid waste, sewage, manure, etc.)
3. Solar electric
- solar thermal units: used to redirect sunlight to produce heat which in turn generates electricity
- photovoltaic's: solar cells which convert sun energy into direct electricity
- wind and windmills: utilizes wind to produce electrical energy
- ocean thermal electric: converts solar radiation from the ocean's thermal gradient to electric power
- hydropower: utilizes water to produce electricity
Hydropower generates more energy than any of the other renewable resources without supplying the atmosphere with carbon dioxide
Hydropower is a long term replenishable resource unlike declining fossil fuels
***90% of renewable energy is produced by hydropower***
Non-renewable Resources:
1. Nuclear
2. Fossil fuels (coal, gas, oil)
