How it Works

Lighting up the town with sunshine


Whether rooftop panels are placed on your home or business or installed at a community site or solar farm, solar power is one of the most used, most cost-efficient sources of green, renewable power. When the sun shines down from above, solar cells contained within panels capture and transform rays of sunlight into clean electricity that is sent out to the power grid. With 180 solar projects in 16 states, Duke Energy uses solar power to reduce our dependence on fossil fuels and combat carbon emissions.

Harnessing the Power of the Wind


Like the name suggests, wind energy comes from using just that: the wind. As the sun heats up the Earth, hot air rises while cool air fills the space. This movement of air creates wind that, with the help of wind turbines, is captured and becomes a no-carbon-emission energy source.

Harvesting organic plant and animal material to generate energy


Did you know that we can convert the waste from plants and animals into electricity that can power your home? It’s true; biopower transforms organic waste or byproduct into a renewable energy source. Biopower uses direct combustion to turn organic waste material from wood, crops, manure and some garbage into clean energy. While making a resource out of waste, biopower can also positively impact the environment and agricultural economies.

Making waves of electricity from moving water


Water contained in lakes held by a dam has incredible potential for creating clean energy. As water spins turbines, the turbines rotate a generator that produces electricity … hydroelectricity. Even better, hydroelectric energy doesn’t consume any water, which actively supports water’s constantly regenerating natural cycle. Plus, no greenhouse gases are produced.

Capturing and converting gas from landfills


As garbage and waste decompose in a landfill, gas is released. Much of this gas contains methane and carbon dioxide – both potent greenhouse gases. Instead of allowing the gas to escape into the air, the gas emissions are collected, treated and converted into electricity for customers. Used as renewable energy, landfill gas can minimize waste and help reduce emissions that contribute to climate change.
