Westar’s 2017 energy mix

Over the last 10 years, we've made remarkable progress with renewables. By 2017, we will produce the equivalent of nearly 1/3 of all the energy used by the homes and businesses of our customers from renewables.

 

Westar’s 2017 energy mix

Capacity as of 2017

At Westar, we generate electricity from a variety of energy sources, such as fossil fuels, nuclear and renewable energy. Although renewables are a key part of our mix and our future, they need to paired with traditional generation sources to provide the 24/7 power our customers expect. We believe the best approach to meeting the needs of our customers and our state is to diversify by using some of each method. This ensures that we can keep your electricity reliable and affordable even if the sun isn’t shining and the wind isn’t blowing.

Fossil Fuels

What are fossil fuels?

These are fuels that come from very old geologic deposits of organic material – hence the name ‘fossil fuels.’ They are converted to coal and natural gas through exposure to heat and pressure, which is then used to generate electricity.

Renewable Energy

What is renewable energy?

Renewable energy is energy from natural sources that are continually replenished, such as sunlight and wind. Westar harnesses Kansas wind and sun to generate electricity. Since renewable energy comes from a natural source, it is free from emissions.

Why can’t we go 100% renewable?

As Kansans know, we can’t predict the weather. Sometimes the wind won’t blow and the sun won’t shine but our customers still want power. In order to provide affordable and dependable electricity 24/7, we must rely on clean coal, natural gas and nuclear energy to deliver when the renewable sources do not. Due to their reliability, controllability and affordability, these sources must supplement our renewable energy mix.

That being said, we want to preserve Kansas’ environment for generations to come. We are growing our renewable energy program to sustain natural resources and reduce our carbon footprint.
