Issaquah and Sammamish residents took energy savings to the bank last year.

About 9,000 residents from the two cities saved about $376,000 through the Home Energy Reports program.

Seven Eastside cities participated in the program with a net savings of about $4.2 million over a 14-month period.

The program compared a recipient’s household energy usage anonymously with similar households in his or her neighborhood.

The results showed that most residents read the reports, and many responded by changing their habits, which resulted in lowering their energy bills.

Issaquah’s 5,000 residents saved about $216,000, including about 80,000 therms of natural gas.

The 4,000 participating households in Sammamish saved over 724 megawatt-hours of electricity, over 65,000 therms of natural gas, and $160,000 in real financial savings.

“Sammamish residents care about the environment and this program shows how better information can lead to great decisions,” City Manager Ben Yazici said. “We appreciate the chance to work with PSE and the C-7 partnership to save money and improve our environment at the same time.”

About 90,000 residents were invited to participate in all.
