The Clean Energy for Low-Income Communities Accelerator (CELICA) aimed to lower energy bills for low-income communities through a voluntary partnership between DOE and state/local governments. The goal was to better understand and address low-income energy challenges and demonstrate a wide range of locally designed energy efficiency and distributed renewable energy solutions. Low-income households spend about 8% of their income on energy costs, three times more than non-low-income households. Partners committed $335 million to help 155,000 low-income households access energy efficiency and renewable energy benefits, collecting resources and lessons learned into the CELICA Toolkit.
