The Neighbor to Neighbor Energy Challenge was designed to encourage Connecticut residents to reduce their energy consumption through home energy assessments; efficiency upgrades, including switching to CFL light bulbs; and solar installations. The Challenge offered residents discounted rates for energy audits and connected them to state rebates and zero or low-interest loans for energy upgrades. Fourteen towns participated. For each individual action taken by a resident the town earned points toward rewards ranging from smart thermostats to electric vehicles. The Challenge was administered by the Connecticut Clean Energy Fund and supported by a $4.17 million grant from the US Department of Energy’s Better Buildings program.
