Northwestern Energy volunteers help install insulation in Habitat for Humanity homes

The volunteer work was being done on Energy Efficiency Day in which Northwestern officials educated people on things they can do to save energy in their homes.

“The cheapest kilowatt hour is the one you don’t use; even something as simple as an LED lightbulb, or a low-flow shower head, or faucet aerator, you’re decreasing your energy use which ultimately decreases your energy bill,” said Williams.
