Just got my January gas and electric bill. Gas usage was 40% less than last year, electric use was 3% more. Bill was $536 -- nearly all of that on the electric side. The utility says our annual bill is roughly $5K/yr.
I have kids who are partly homeschooled and I work from home, plus we always cook at home rather than eat out. We do use quite a bit of electricity, but there isn't anyway around that. We've already switched all lights to LED, upgraded the HVAC to be super efficient, turned down the temperature in the winter. One of my sons is modestly allergic to contaminants in unfiltered air, so instead of windows we have a hyper efficient ventilation system that pushes air through two filters on the way inside the house and ensures there is minimal heat loss (doctor prescribed)...this ventilation system is run as cheap as we can configure it. We're also on a medical baseline discounted use plan. We have a solar heated pool with ultra efficient pump.
There are 3 pricing tiers - 20 cents/kwh for tier 1. 25 cents/KWH for tier 2. And, 30 cents/KWH for tier 3. We average between 1,350-2100KWH/month w/ usually half of our usage in tier 1 and the other half in tier 2. There are also taxes...I calculate my average rate as between 23.5-24.5 cents/kwh depending on the month.
The offered time-of-use plans don't really provide any discount....and honestly, the C-Max utilization would count for under 40KWH/month as I don't have to make a daily commute. The utility estimates all time of use plans will cost us more and I'm not going to tell the kids and rest of the family not to cook dinner or do their homework in the early evening to save electricity during their max-rate time period (4pm-9pm).
The state told us not to even bother applying for the EV rebate since we actually make enough $ to pay real taxes. On the other hand, they would increase the rebate substantially for anyone in poverty. Why someone in poverty should be buying an EV car, I have no idea. Nor, why the state has to both charge higher tax rates and cut rebates/services for those w/ higher incomes. But, this is California...nothing makes sense.
The only real solution seems to be to put in place both a large solar electric panel system plus several batteries and then switch to a time of use pricing plan and then generate and store power during the day and draw down power from the batteries from 4pm-9pm. This won't be cheap to setup and install, but over 10+yrs will end paying for itself.
