One of the arguments I always felt favored EVs is that there are numerous ways to generate electricity including doing it yourself. So once you start producing your own electricity and powering your EV with it, energy conservation is very on topic.
In my case I'm looking to conserve elsewhere to have more for driving :) Damon ________________________________ From: EV <ev-boun...@lists.evdl.org> on behalf of Damon Henry via EV <ev@lists.evdl.org> Sent: Thursday, July 26, 2018 9:33 AM To: Electric Vehicle Discussion List Cc: Damon Henry Subject: Re: [EVDL] Charging load on the grid (NOT) This is actually a very relevant topic for me right now, so thanks for all the great information. I just had an 8kw solar system installed on my roof. According to production projections and past consumption trends this will provide roughly 70% of my annual usage. So how do I take care of the other 30%... Well, it's time to take a hard look at where I can conserve. Also, we currently do around half our household driving on electric, and I would like to push that up in the next couple of years, so I need to actually find more than just the 30% savings. In the end I suspect that I will need to add more panels, but that will take some creativity as I got as many put on my southern facing roof as there was room for,,, I love seeing the energy collected from my roof and funneled directly into my "gas tank". My electric vehicles just became solar vehicles :) Damon ________________________________ From: EV <ev-boun...@lists.evdl.org> on behalf of paul dove via EV <ev@lists.evdl.org> Sent: Thursday, July 26, 2018 5:17 AM To: Electric Vehicle Discussion List Cc: paul dove Subject: Re: [EVDL] Charging load on the grid (NOT) Matt, I believe this is the point the author was trying to make.
