Yes. Such ways include…

As for the thermostat suggestion, there are many who invest in smart thermostats to regulate the temperature in their homes. For instance, a Google Nest E Smart Thermostat or ecobee3 lite Smart Thermostat can save homeowners a great deal, despite the initial investment.
Ecobee, for instance, asserts that their thermostat will “save 23% on annual energy costs.” That’s a lot of savings.
In short, we should all explore as many ways as we can to save on energy costs. It’s not only good for the environment, it’s good for our wallets.
