Delaware Sustainable Energy Utility (DESEU) is who we are—a nonprofit 501(c)(3) organization created by the State of Delaware. Through our many Energize Delaware programs, we help residents, businesses, farmers, schools, religious organizations, nonprofits, hospitals and local governments save money. We do it by providing access to high-efficiency heating, cooling, ventilation and insulation technologies at little or no cost.
Making Homes More Comfortable and Affordable.
Our programs help improve your home’s coziness and safety while reducing its energy consumption. In-home energy audits identify exactly what’s needed—from new insulation, windows or doors to higher-efficiency appliances and HVAC equipment. All to make your home more comfortable and affordable.See our residential programs
Improving Bottom Lines For Businesses, Government and Nonprofits.
We also help companies, governments, nonprofits and faith-based organizations save energy and money.
