No matter how cheap solar energy becomes, it won't be a complete solution until the energy storage problem is solved. I don't see the same rate of progress on that. If you can't store the energy you'll need a backup that can supply the missing power when the sun isn't shining - you'll need to keep building the old fashioned power plants even if you don't run them as often. Unfortunately there's no guarantee that prices will rise at the time and pace required for efficient uptake of new technologies. The easiest way to reduce demand is to tank the economy. We got a taste of that in 2008, and I'm not looking forward to it happening again.
