[QUOTE="rfc805, post: 1822808, member: 62787"] I think your understanding of electricity is a bit incomplete. Generally, we measure and pay in kWh, which is a KW for an hour, as the name would imply. An electric clothes dryer tends to use about 5-5.6kW while running. So, your 1 hour example, 5.6kWh. Here, where admittedly in the Midwest we have reasonably cheap electricity, we're about $0.10/kWh delivered. Makes the math pretty easy, $0.56 per 1 hour, or $2.24 for the 4 hours you mention. Once you know your delivered kWh cost, knowing that the Lightning ER is a 170kWh battery also makes this math very easy. Note that modern EVs reserve a good 10-15% of that battery, so you'll not really find yourself discharging/charging the full amount, so call it 150kWh if you fully drain it. It does not really matter how fast you charge it, 80A, 20A, 40A - it just changes the rate. The amount remains the same, and costs the same. 150kWh * $0.10/kWh, $15. If you take the 'delivered' part out (the cost you pay to have service hooked up, billing, all that) it's about $10. There are cheaper places than here, so $8 is definitely not out of the realm of reason. On the flip side, if you go to some of the more expensive places I've heard of (Mass, SoCal) I think it gets up to $0.30/kWh - and that's $45, still not bad. Gas/Diesel tend to be higher there as well, which is no surprise. Now, from what I've seen commercial EV fast charging stations tend to charge more like $0.40-$0.70/kWh. As a result, they end up a lot more similar to filling up a combustion vehicle in price. Anywhere from $60-120 is probably realistic. Your clothes dryer is also definitely not the biggest energy hog in a household. The reasoning is largely efficiency. Your refrigerators/freezers and AC being the more inefficient systems will use the most. The resistive heating elements and motor of the electric dryer will be nearly 100% efficient, which is an important thing to understand in larger terms - because EV drivetrains follow that rule as well. ICE engines, by comparison, are only even theoretically in the high 30%s of efficiency if I recall correctly. Practically, we're more in the 20% realm. [/QUOTE]
