Clean Heat

Sierra Club’s Clean Heat campaign is working towards a future where all U.S. homes and small boilers are healthy, efficient, and powered by 100% renewable electricity. 


Transitioning to clean and healthy fossil fuel-free buildings and industrial facilities plays a critical role in meeting our climate goals, protecting public health, and ensuring energy is reliable and affordable.

A household's access to energy is essential to health, comfort and well-being. But many households suffer from a high energy burden and struggle to pay their energy bills.

Energy Burden Calculator

The Energy Burden Calculator can be used to help you estimate the percentage of your income that is spent on energy expenses (electricity and home fuels). Generally, a household energy burden over 6% is considered unaffordable.
