Officially, today, 29th at 1600 EDT, our home was free of using fossil fuel energy.
We now have:
- A 10 kW nameplate SunPower/RevoluSun solar array on our roof, which generated 49 kWh today, and gives remarkable, over-the-top performance despite there being tree shading and a high western horizon. And to my continuing surprise, that’s because our Massachusetts skies often have bright clouds floating by.
- 3 Fujitsu air heat pump “ductless minisplit” systems for heating and cooling, all electric.
- A General Electric GeoSpring 50 gallon air heat pump hot water heater, all electric.
- Signing with MassEnergy/New England Wind for all energy we use above and beyond what we generate, that is, above what we store and get back
We do have our oil fed furnace on emergency standby for hot water and heat, and electricity backed up by a propane generator, which is far from enough to power the house. We presume we won’t have to rely upon these for any extended duration. Alas, with the current hookup, consistent with Massachusetts regulations and those of Eversource, if the grid goes down, so does our solar generation. Who knows?
While it would be a bad thing for Massachusetts, if Beacon Hill decides to stab solar energy in the back, we’ll eventually move to another model, where we are more independent of all of it, and, under that model, our solar will not go down when the grid does. The only reasons we do not have it configured that way now are:
(a) we’d like to share our spare electrons with our neighbors,
(b) we are not eligible for SRECs if we do configure it that way, and
(c) energy storage options are not financially sensible at present, even if they will be in 5 years or so.
So, it’s …
fossil fuel freedom day
At least for the house. Now, about those cars ….
By the way, if you want to watch our panels power their way through the summer and years, bookmark and follow this link. And note all the others in the world who are doing the same.
By the way, I forgot to mention that we have an electric lawn mower, powered by a battery, and have had one for a few years. We purchased a second battery because, while the one battery generally does the entire yard, once in a while the lawn is lush enough to demand a bit extra energy.
We are, of course, also moving away from a traditional lawn. We of course put no fertilizer on it and certainly no weed or insect killer. We’re not supposed to, as we are close to wetlands. Our neighbors aren’t supposed to do that either, but we fear (and have evidence that) some of them do anyway.
