At home, you can save money on energy bills by making energy-efficient and weatherization upgrades—such as adding insulation, using LED lighting, and installing a heat pump—that reduce your energy use and can improve comfort.

Energy-efficient buildings cost less to heat, cool, and operate, while industry and manufacturing plants can make products at lower cost. Energy-efficient transportation results in fuel savings.

Energy-efficiency programs improve community resilience and address energy equity by bringing efficient, cost-effective technologies and infrastructure to underserved communities, including communities of color.

These communities are disproportionately affected by air pollution and have a higher energy burden, which is the percentage of gross household income spent on energy costs.

Reducing energy use is essential in the fight against climate change, because traditional power plants burn fossil fuels that release greenhouse gases and contribute to air pollution. Energy-efficient homes and buildings are also better equipped to switch to renewable energy, which does not produce harmful emissions.

Energy-efficiency improvements reduce the amount of electricity on the grid at one time, known as load, minimizing congestion and stress on the U.S. electric grid. Less load prevents power disruptions.

Reducing fossil fuel use results in cleaner air, water, and land, all of which directly affect human health—especially those in marginalized communities and people with conditions that are exacerbated by pollution.
