prompted former Premier Ed Stelmach's government to commit $4 billion to a province-wide green capital projects plan in 2009. In 2009 former Calgary Mayor Dave Bronconnier and Pembina Institute were awarded the 'Reaching Out to Global Energy Award' at the UN Climate Change Summit for the technical and engineering collaboration with Calgary's "Greening the Grid" program. Pembina scholars compiled the 'Options for Reducing GHG Emissions in Calgary' to advise the city on how to implement infrastructure projects for environmental protection. The city acted on these recommendations through city-owned company Enmax; decided on a series of public works facilities such as the Shepard Energy Centre, and a 12-turbine wind farm that supplies wind power for Calgary Transit's C-trains, and the District Energy Centre, a heat capture energy plant providing heat and energy for the downtown core. The city publication of the "Greening the Grid" was entitled "Calgary Climate Change Action Plan: Target (down arrow) 50" (Target Minus 50). The "Greening the Grid" program's objectives are to empower city facilities by renewable sources by 2012. Calgary Transit's C-trains' electrical needs were partially provided by wind power in 2001, by 2009 the inception year of "Greening the Grid", the CTrain were fully empowered by "Ride the Wind", a program launched by Enmax and wind power engineers Vision Quest Windlectric. committed $250 million on the 'Greening the grid' program. In 2013, Sun Media journalist Ezra Levant said the city of Calgary contracted $340,000 to Pembina which he accused of being an anti-oil lobby group with insufficient scientific credentials. Sun Media journalist Renato Gandia mentioned the Pembina Institute's contracts in an article with the headline "Mayor Naheed Nenshi says work done by left-leaning Pembina Institute think tank was not political in nature". Nenshi said it would be reasonable to hire the "best guy" regardless of personal political values. The affair concluded with a Twitter argument when Nenshi responded to Levant's questioning. Levant questioned Nenshi about the ethics of city funds going to Pembina, if Pembina staff had worked on or donated to Nenshi's political campaigns. Nenshi responded by asking Levant rhetorically 'when did you stop beating your wife?' Enmax Nenshi ordered a corruption graft probe into the finances of city-owned utility company Enmax after an unknown senior employee revealed lavish spending by former Enmax CEO Gary Holden in 2010 in an email report. Holden was reported to have organized extravagant house celebrations entertained by rock
