The chart below shows the average monthly electricity use by the Carleton campus compared with the production by the college’s wind turbines as well as the individual turbines. Electricity production is expressed in kilowatt hours (kWh) and is shown since turbine #2 came online in late 2011.
Since the second turbine came online, the two wind turbines together have been providing, on average, 70% of Carleton’s monthly energy usage. The average monthly energy usage is taken from Carleton’s average monthly energy usage in 2011, which was 1,180,196 kWh per month.
Though these data cover only the first six months that the second turbine was online, it shows that the turbine is meeting its goal of providing one-third of Carleton’s electricity usage.
