Although there are more residential buildings in the community, these strategies result in relatively smaller emissions reductions than the more energy -intensive commercial and industrial sector. This means that the city will have to consider how to best balance its efforts against the impact and avoid burdening resources for a smaller result. The city should focus its outreach efforts both on high energy users (as identified in the PiE Energy Action Plan) and low- income households. High energy users will have greater opportunities for efficiencies, and low-income households may be burdened by unnecessarily high energy bills. GOAL 5: Achieve 100% renewable electricity by 2030 Strategies • Commercial/Industrial Green power purchase Commercial: 0 40% of businesses (-920) purchase all their electricity from green power by 2020 o All businesses purchase all their electricity from green power by 2030 (36.3% of total building emissions in 2030) • Residential Green power purchase Commercial: 0 40% of households (-9,840) purchase 100% of their electricity from green power by 2020 o All households purchase 100% of their electricity from green power by 2030 (14.1% of total building emissions in 2030) • On -site solar photovoltaic (PV): Meet 10% of building electricity consumption with rooftop solar by 2030 (5.6% of total building emissions in 2030) IMPACT: By achieving 100% renewable electricity by 2030, these strategies are estimated to result in a 56.0% reduction in total building emissions in 2030, which equates to a 33.3% reduction in community -wide emissions. These savings do not account for changes in electricity electric vehicles or fuel switching from natural gas to electricity.
