Green power offers a more environmentally friendly option for producing electricity. Greenhouse gas emissions are reduced by using renewable energy from water, wind and sun in place of sources such as coal and natural gas. ENMAX currently provides wind-generated green power.The City’s green power commitment of 7,840 megawatt hours in 2009 will increase to over 16,000 megawatt hours in 2013. This latter amount has the same positive impact on the environment as reducing 14,000 tonnes of carbon dioxide, or the same as taking 3,083 cars off the road for one year (based on fuel economy of a 1998 Taurus according to Natural Resources Canada and Carbonzero).
