Earlier this year a group of national, regional, and local energy efficiency pros met to decide what we should ask people to do to make the greatest impact on energy efficiency across the United States. What is the big, bold action we are looking for to show people how to save energy and save money? What is the cutting-edge technology that we should urge people to adopt to slash their energy usage? It turns out that the best ask today is the old ask: Change a light bulb. So that’s what the Energy Efficiency Communicators Network, of which AEE is a member, is going to do for this year’s national Energy Efficiency Day, which is planned for October 5. Because it turns out that there are a lot of old light bulbs still burning, and wasting energy, out there.
