What is energy efficiency?
Energy efficient homes and buildings have lower energy costs, decrease reliance on fossil fuels, help manage energy demand, and create jobs. This includes high-efficiency heating, ventilation, and air conditioning technologies like heat pumps, energy and water-conserving products appliances, and efficient lighting. Energy efficiency includes weatherization, which involves the installation of energy-efficient insulation, windows, and doors, alternative building materials, weather-stripping, caulking, and more.
