There are generally ten types of energy: Fossil Fuel, Nuclear Power, Solar Power, Wind Power, Tidal Power, Hydroelectric Power, Pumped Storage, Wave Power, Geothermal Power and Biomass. Three major sources of energy are used in Ontario - Fossil fuel, Nuclear Power, and Hydroelectric. Of the non-renewable energy sources, Nuclear power is a lot more environmentally friendly than Fossil Fuel as it doesn't emit greenhouse gas. Although, the radio active waste produced is a huge concern to safety and the environment.
Of the renewable energy sources, currently Japan plans to use biomass to help improve their environment, and both San Francisco and Dubai are harvesting Solar Energy to aid their environmental efforts.
For heating and cooling, Geothermal energy seemed sound for keeping indoor environment comfortable, and be a great resource that does not damage the environment. Using Solar energy to heat water indoors will both save money and the environment.
FCL, florescent compact lighting, is very sound for the environment using less electricity and running longer. This helps to keep a lot of the greenhouse emissions from the fossil power plants from entering into the environment.
