WIND |
Energy production does not produce greenhouse gases | Old designs emit noise |
| Does not contribute to global warming | Some people do not like the visual impact created | |
| Farming and grazing can continue on land where wind turbine is located | Wind does not always blow or remain constant | |
| Renewable resource | Barriers to bird movement | |
| Inexhaustible | Cause fatal bird collisions | |
| Produces fuel source that can never be depleted | – | |
| No air pollution | – | |
| No water needed | – | |
| No need to tear up the ground or destroy habitats | – | |
| Small environmental footprint | – | |
| New designs emit minimal noise | – | |
| One wind turbine can supply a large area with energy |
