Or change your routine so that the availability of energy and demand happen at the same time.
For an example, I don't have room in my little house for a full sized oven. Plus it would need to be wired or plumbed in. So I've thought about making a solar oven. Of course that would mean I could only bake on sunny days.

Well that's where a fall back energy source comes into play. This is why I've come to understand that plugin hybrids really make a lot of sense. A solar charged hybrid could work under the same principal.
- When you have the better energy source available, you can use it.
- When you don't you can fall back onto the alternative.
- This is better than full turkey one or the other because full ICE is taking 0 advantage of solar, plugin, etc. and full BEV isn't to the point where it's affordable and practical for most people, including myself.

Why can't you have both for now? What's the drawback? Sure, it would be great if we could all strap on panels on our cars and never have to plug in or fill up with gas ever again. But even though that's not possible, if PV helps you use less fuel, then it's still helping, isn't it? Or should I just go get an old Hummer at about 6mpg for my daily drive just because I have to use gasoline anyway so there's no point in using less?
