    What Customers Accomplished in 2014

    More then 481 Million kWh Saved, and nearly 850,000 Dth of Natural Gas Saved

    Thats enough energy to power over 70,000 Twin Cities homes for a year

    Environmental Impacts Reduce emissions

    1.054 lbs CO2 / kWh (1.161 lbs CO2/kwh - 2012) 11.7 lbs CO2/thermSince 2005, we have reduced CO2 emissions by

    over 12%, SO2 emissions by 40% Pollution prevention

    Avoid new power plantsMore than 3,000 Megawatts of power saved 11 mid-sized power plants
