I'm not sure electric cars make a lot of sense for a large part of the population yet, either. But your comments confuse me a bit too? For starters, solar energy and battery technology really have to go hand-in-hand for solar to make a lot of sense. Right now, we have a bunch of people living in sort of a fantasy-land that slapping $35,000 or so worth of solar panels on their home's roof will give them all the free electricity they need. Yet what *really* happens is they wind up generating about $90-110 worth of power per month (on average), most of which gets dumped back onto the grid between the hours of 10AM and 2PM when the sun shines on them optimally. If too many people in one small area go solar, there's more power generated in that time window than there are customers for it on that segment of the power grid, so some of it just goes to waste.
There are big power losses involved with transmission of power down long lengths of lines, so it doesn't make sense to push the electricity long distances. So PV solar needs to be making power close to where it's actually needed, at the time it's generating it.
And obviously, NO power gets generated as soon as the sun goes down -- yet that's when much of America is just getting home from work and using power for things like hot water for baths/showers, fixing dinner, watching TV before bed, and maybe washing and drying a load of laundry.
If you want solar to become a real solution, you're looking at marrying it with better, cheaper battery technology.
