Organizations across the country are using energy efficiency day to inform and empower residents to make energy upgrades to their homes and businesses.

More than 200 companies, government agencies, utilities, and others participated in Friday’s third annual National Energy Efficiency Day.

“Opportunities like having Energy Efficiency Day to send a message, to talk about using less has tremendous benefits, if you can get what you need without using as much, it saves you lots of money,” said Steve Cowell, president of E4theFuture.

The American Council for an Energy-Efficient Economy has applauded Massachusetts for its clean energy policies, particularly through the state’s Mass Save Program.

The Mass Save website details techniques, services, and switches that can be installed for free by your utility company.

A 2016 study found that Massachusetts’ clean energy industry currently employs more than 52,000 people across the Commonwealth.

By participating in Energy Efficiency Day and utilizing tools like the Mass Save website, residents can dramatically reduce the energy use.

For the eighth year in a row, Massachusetts has been ranked first in the nation in energy efficiency, a trend they intend to continue.
