. . . "you have to earn solar."
What this means is that if your home is inefficient in energy use,
. . . . . . due to old,
. . . . . . poor-performing appliances,
. . . . . . lack of proper insulation, or
. . . . . . air sealing,
. . . then the energy created from solar is going to largely be wasted.
This pyramid diagram,
. . . is a useful tool to show the loading order of home energy upgrades.
It all begins with the base of the pyramid,
. . . with an increased general understanding, and knowledge.
. . . A homeowner can be educated by having a home energy audit, or
. . . by reading about various methods, tools, and practices,
. . . to help make a home more energy efficient.
From there, the homeowner can move up the pyramid,
. . . to items that are more complex and/or require more of an investment.
Not every upgrade is going to be appropriate for each home.
. . . This is why it is important to work with experts in home energy efficiency,
. . . to maximize your specific results.
