It started as a project to power Calgary’s LRT with wind power in 2001, but in 2012 the City entered into an agreement with Enmax to supply all of the city operations, including the LRT with wind power from southern Alberta making the city operations 100% renewable. Calgary needs 144 megawatts of electricity to operate trains and run city operations. That emissions reducing effort is now poised to provide a major payback of almost $10 million per year in avoided carbon taxes. Photo David Dodge, GreenEnergyFutures.ca
