- Sustainable energy does not alter biodiversity or ecosystems.
-Renewable energy sources are not reduced by use, or they can be renewed.
- Coal is the worst choice of a fuel to use. It is rarely used today.
- Coal is the worst choice of a fuel to use. It is rarely used today.
- Coal releases carbon dioxide and other green house gases harmful to the environment.
- Often not thought of is the effect coal has on mining communities. It often ruins the ecosystems around it especially in "mountaintop removal."

- Oil is not only harmful to the environment because of its greenhouse gases, but is is also nonrenewable.
- The combustion of oil is what cause the emission of greenhouse gases and other damaging pollutants.
- The combustion of oil is what cause the emission of greenhouse gases and other damaging pollutants.
- Transporting oil risks spills that are very harmful to wildlife and drilling for oil upsets the local environment.
- Propane and natural gas also cause similar problems because they are fossil fuels ans are not sustainable.
- Propane and natural gas also cause similar problems because they are fossil fuels ans are not sustainable.
- "The Environmental Protection Agency, however, found natural gas to have the fewest relative emissions of fine particles -- fewer than oil, pellet stoves or wood stoves." However, pipelines for natural gas have a negative effect on the ecosystems around it just like coal and any other mining or shipping of fossil fuels.
-Propane needs special procedures to be separated and refined that are harmful to the environment.
- Electricity is only sustainable when is comes from solar, wind, or hydro systems.

Forestry must engage in "selective uneven-age harvesting and replanting" for it to be sustainable.
-When a tree is alive it takes in carbon dioxide and turns it back into oxygen, so the life of the tree will account for the carbon dioxide released into the air when the wood is burned.
- An equal amount of carbon will be released into the environment whether or not a tree is burned or simply decays in the forest. Coal, oil, or gas will not naturally release their carbon dioxide "without human intervention."
- "Pellet stoves [are] ... fueled with compressed sawdust, wood chips, bark or other organic matter, or biomass fuels like nut shells, soybeans, corn kernels or cherry pits. "
- In a geothermal system, heat is drawn out of the earth through pumps and moved throughout your house to warm it. A small amount of electricity is used when the warmth is circulated around the house, and if that electricity comes from wind, solar, or hydro then the whole process is sustainable.
