There is plenty of evidence that retrofitting large buildings to increase energy efficiency. What I am interested in, is what do middle class USA citizens need to do to increase energy efficiencies in their homes and where do they go to get the money to accomplish the task without bankrupting themselves and future generations?
We switched from electricity from fossil fuels and nuclear to a provider that uses only wind and solar. One can also get an energy audit, to find out the most cost effective ways to reduce your energy consumption. We bought a nanoleaf bulb which is supposed to be the most efficient LED bulb of 100 watt equivalence. But we had to wait many months. They're still gearing up for mass production.
This is quite remarkable. Have you received your nanoleaf bulb? Will it fit in in any lite fixture? What about holding the shade in place? Oh! This is exciting.
