See my reply to Zeronet for some details, but we already have done the appropriate mitigation of use. It is much more challenging to retrofit an existing home to make it more energy efficient. Our home stated out as a pole barn and was finished out as a house in the 1980's by its original...

We actually upgraded our attic insulation from R-36 to R-90 after having the ceilings air sealed in the attic. We also replaced all of our windows and replaced our propane furnace with a ground source heat pump, and have added direct solar PV water heating. There are significant differences in...

Here's a Sense (R) screenshot of our combined wind and solar PV production (in orange) and usage (in green) for 2020. The batteries were installed in the end of 2020 and really didn't become functional until January due to a Gateway which got "bricked" during a critical initial update from...

Here is an video without narration which gives an overall view of our system as it is installed on our property.

Here is a link.to another video about our system. Not narrated. Returning home after an overnight shift in the hospital. Here is what I see when I drive upto our home and plug in our electric car, powered by wind and sun harvested on our property. "We drive by perpendicular magnetic fields...

Here's a link to a short video about our system.

We have wind turbines as part of our Tesla Powerwall 2 system. Like solar PV, they need to be correctly sited, and installed by people who understand the technology. We have 4 Skystream 3.7 turbines as part of our overall system. They are on 45' monopole towers. They help balance our system...

Here's a link to a short video about our system. Enjoy.

Our home is all electric in a cold climate. The ground source heat pump is a 5 ton system. While cooling in summer isn't a big load here compared to sun/wind power generation, in winter, here in Cheyenne, Wyoming heating the house is. We easily can use 20 - 30 kWh per vehicle and 30 - 70 kWh...

If we lived where there was colder ground temperatures, such as in the arctic that might be true, but not so much in our climate. New construction uses that, but no one around attempts such a retrofit. It simply is cost prohibitive. Doing our insulation project of removing the old R38 blown...

A Powerpack is equivalent to about 17 Powerwall 2 units. The Tesla Powerpack is not available for residential installation at the time we installed our Powerwall 2 system, and as far as I know is still not available for residential installation. Powerpack entry level costs are about 2-1/2 to 3...

A Powerpack is up to 232 kH per Powerpack. A Powerwall 2 has 13.5 kWh of usable power with a rating of 14 kWh. So a Powerpack is roughly the equivalent of 17 Powerwall 2 units.

We love the Skystream 3.7. 2 were installed in 2012, and 2 more in 2019. They are virtually zero maintenance, but things will wear out. They are appropriate for our specific needs. They are not for everyone or every installation.

I'm not familiar with it. Since most heat is lost through the ceiling, as heat rises, that is where we started. I'm skeptical about retrofitting foundations as being effective for much of anything. If you technical information about it, I'd be interested in seeing it. Thank you.
