The recommendations path illustrates a path that you can follow to take your home from its current state to net zero, where your home will produce as much energy as it consumes. Each colored arrow represents a step on the path and appears in order of return on investment, from left to right. Arrows with a dark border will actually make you money over the long run. Other steps may save energy or money, but are not expected to provide a long term return on investment. Arrows with the lightning bolt icon require switching from fossil fuel to electricity, which helps reduce carbon emissions.


The length of each arrow represents the amount of energy that it will save and its contribution toward reducing your home’s energy and carbon footprint. Hover over an upgrade to see how much it might cost and how much energy you might save. Click on an arrow to learn more about the upgrade and to see utility savings estimates that are customized to your home.
