People keep saying this, but does anyone actually have numbers to back up the claim that things are going to get really bad? The reason I ask is due to an NPR segment that aired last week about a Texas power company. They described the different types of energy they were using as well as how long it takes to "turn them on". There were order of magnitude differences between the various power sources. The more efficient the power, the longer it took to start/act to changes in demand. If more people are using local solar, then peak hours during a summer day would help level out usage: more sun = more local energy that will be used for AC. I would imagine that change would allow these companies to save a lot of money by not having to use the less efficient power sources to properly adjust available power. That extra money can then be spend on the infrastructure or more R&D. I'm just curious because I keep hearing crap like "solar is going to completely kill the grid and costs will skyrocket as people leave."
