Residential Energy Efficiency

Buildings account for about 40 percent of greenhouse gas emissions, and residential buildings account for a significant share of this. Over the last two decades, several high-efficiency residential energy systems powered by alternate energy sources have been developed. These systems can lower greenhouse gas emissions and utility expenses, and reduce indoor pollution. Yet U.S households have been reluctant to adopt them for a variety of reasons. To help overcome barriers to technology adoption, several policies and programs by federal, state and local agencies and governments aim to incentivize households to adopt high-efficiency or renewable-energy-based heating and cooling systems.
