Frequently Asked Questions
Is renewable energy practical in Connecticut's climate?
Yes. Solar panels work well in cold, clear weather, fuel cells provide continuous power regardless of conditions, and offshore wind benefits from strong coastal winds. Combined with storage and efficiency upgrades, renewables can meet a significant share of energy needs.
What is a fuel cell and why is it important here?
A fuel cell generates electricity through an electrochemical reaction rather than combustion, producing power with fewer emissions and high reliability. Connecticut has a long history of fuel cell research and manufacturing, making it a regional strength.
Can businesses finance renewable projects without large upfront costs?
Options include power purchase agreements, leases, commercial property assessed clean energy financing, and green bank programs. These structures allow organizations to begin saving on energy costs with little or no initial capital.
