84% of Westar customers aren’t aware of Westar’s involvement in renewable energy

Significant gap exists between customer

awareness and Westar performance

TAKING RENEWABLE ENERGY TO HEART 10

Awareness gap doesn’t mesh with reality

• While there is strong interest in renewable energy within Westar customer base….

• Significant gap exists between public perception and the reality of Westar renewable energy initiatives:

10% of Westar energy generation capacity is powered by wind.Westar owns or purchases power from 5 wind farms, providing enough energy to

power over 250,000 Kansas homes each year.Westar wind farms reduce production of carbon dioxide (CO2) an equivalent

amount to that generated by 125,000 passenger cars per year.Through the efficiency of Westar wind energy generation, enough water is saved to

supply the consumption needs for over 19,000 homes each year. Westar landfill gas generation supplies the energy needs of 5,000 homesIn addition to using solar systems to offset energy requirements at multiple

company locations, Westar will provide solar energy systems to 15 to 20 non-profit groups by the end of 2016.
