Vehicle to Home and Vehicle to Grid.

V2H (vehicle-to-home) uses your EV to replace your back-up generator

V2G (vehicle-to-grid) uses your EV to reduce peaker-plant usage on the grid

•not useful in MA, because we have no (time of day) TOD electrical tariff (there should be!!). A TOD tariff is where the price of electricity is higher during periods of high demand (usually mid afternoons in summer when people use AC) and lower at night. CA has this type of tariff but MA does not.

V2H is already on Nissan Leaf (with charge station) and Ford F150 Lightening.

•It will be standard on Teslas in 2025, all GM EVs in 2026, Kia EV9 in 2024

•This could be accelerated by legislation requiring it, but a bill in CA recently failed

My Ford F-150 Lightening has 100kWh of storage (7x a Tesla Powerwall!), it has 4 x 110V outlets in the truck bed. These can run things like: circular saws, lights, refrigerator, microwave, espresso – awesome tailgating/movies! Plus 220V for V2H.

•It will run my house for 5 days (without the heat pumps), a Powerwall would run it for a day. The F150 Lightening could also charge my Tesla.

•The Ford F150 Lightening costs $75k less $7.5k FTC and $7.5k MA rebate = $60k. Regular Ford F150 is about $45k plus $62k for 7 Powerwalls(=100kWh) = $107k

•The Ford F150 Lightening is a huge battery on 4 wheels. It is also a very nice truck! It has been on order for 2 years. Don’t get a house battery or new generator – get V2H!

Solar panels on the roof of our house

Our heat pumps

This is the insulation on the roof of our house. The pink fiberglass is 10" thick and has an R-value of about R30. The grey boards are rigid foam ISO boards at about R10 each. Insulation is one of the Fab Four of heat pumps, insulation, triple-pane windows and solar panels that got our house to net zero.

These are the triple-pane windows we installed in our living room. Triple-pane windows are one of the Fab Four of heat pumps, insulation, triple-pane windows and solar panels that got our house to net zero. Our new triple glazed windows replaced a mix of 1970's vintage single and double-pane units. The insulating value of the new windows is about 3x that of the old ones. Although it is hard to quantify, our new triple-glazed windows have transformed the look and feel of the house, plus we no longer have to sit under blankets to avoid the cold drafts off the old windows in winter.

Reviews of my “Zero Carbon, Zero Bills” webinar included, “Minute-for-minute, point-for-point, one of the best webinars I have ever attended. Thank you!”, “David is a true inspiration and asset to our community. He inspired us to get solar panels and a new front door”, “This is like a masterclass in ZeroCarbon”, “Thank you soooo much for the sensible advice and your fabulous resources!!” and, although this next comment is a little flowery, it does express the sentiment of many other comments, “Your contribution to Greening America is great and will probably help our survival as a species a bit longer than expected”.
