I think there are numbers of different definitions of clean energy. They all apply to future sources of energy that have a less harmful impact on the environment through their use and through their extraction. Solar energy fits very well into that definition and can also be called renewable, as the resource is not finite. We believe that solar energy has a particularly good value for inclusion in Canada's clean energy future.
When in operation, solar energy creates no emissions, no pollution, no surface water run-off pollution, and no emissions to air. In operation, it's 100% clean energy with no harmful impacts. Manufacturing processes are being improved at present, and the energy payback, the amount of energy that's put into creating these technologies, is often currently recovered within about three years, and that is currently being reduced as well. If that solar technology is in operation for 30 years, then that's 27 years of pollution-free and clean renewable energy.
