Four residential energy efficiency policies were examined: more stringent building codes with third party verification, improved appliance standards and incentives, expanding the Weatherization Assistance Program, and retrofit incentives with increased equipment standards. Their implementation could reduce Tennessee’s projected residential consumption by about 8% (41 TBtu) in 2020 and 11% (72 TBtu) in 2030 (Figure 6).
In 2020, the residential energy required by about 180,000 Tennessean households could be avoided or about $260 per household. The principal energy savings are from electricity (Figure 7). With these policies, residential energy consumption could remain largely unchanged over the next decade, and grow more gradually than the baseline forecast in the following decade.
