Frequently Asked Questions
What incentives are available for renewable energy in Delaware?
Delaware residents and businesses may qualify for rebates, low-interest financing, and programs offered through the Delaware Sustainable Energy Utility, along with net metering and the ability to sell solar renewable energy credits. Federal incentives have shifted in recent years, so confirm current eligibility with your installer or tax advisor.
What is Delaware's renewable portfolio standard?
The renewable portfolio standard requires electricity suppliers to source an increasing percentage of their power from renewable resources over time, with a target of 40 percent by 2035. This policy drives investment in solar, wind, and other clean energy projects.
Can renters benefit from renewable energy?
Yes. Community solar programs, green electricity supply plans from competitive suppliers, and efficiency programs allow renters to support clean energy and potentially reduce bills without installing equipment.
How do fuel cells fit into renewable energy?
Fuel cells generate electricity through an electrochemical process rather than combustion. When powered by biogas or green hydrogen, they can provide clean, reliable power, and they are often used by facilities that need constant uptime.
Are clean energy jobs growing in the Wilmington area?
Yes. Solar installation, efficiency contracting, fuel cell manufacturing, and grid modernization all create skilled jobs. Delaware Technical Community College and the University of Delaware offer training and research programs that help prepare workers for these roles.
