Energy Efficiency

The benefits of energy efficiency include lower utility bills, reduced air pollution and reduced dependence on fossil fuels.

For existing homes, efficiency improvements fall into three categories:

Do it yourself—achieving up to 30% utility savings through simple, low cost measures that are possible even on a modest budget, such as weather-stripping and caulking, installing compact fluorescent bulbs, using ceiling fans instead of central air conditioning, or washing clothes in cold water. Energy saving tips  

Home performance improvements—achieving 30-70% utility savings by hiring a professional to conduct an energy audit, air sealing, installing new insulation (such as blowing in dense pack cellulose into existing walls) and replacing inefficient heating and hot water systems. List of energy auditors  

Deep energy retrofits—achieving 70-100% utility savings through measures such as adding on to existing walls to make room for additional insulation, and installing renewable energy systems.
