It's not about limitless power for free. It’s more about having consistent, reliable and an affordable base load on the grid. My main point is that consumers already complain about their electric bills with the "affordable" type of base load we currently enjoy. I don't think consumers are ready to stomach much more of increase in their monthly energy bills. You need to really think about how much more wind and solar would cost. I'd be willing to bet you wouldn't like the increase. Furthermore, Fukashima was due to an enormous surge of water that flooded the plant, something we will never see here in the Tennessee Valley. Don't fear nuclear energy, appreciate it.
Wind and solar cannot sustain the TVA grid system to make it reliable. The TVA grid can have a load of ~32K megawatts a day during the summer or winter. While this number is unusual, it can and has happened. Where are we going to locate wind or solar farms inside the Valley large enough to carry that load? If we want TVA to abandon Bellefonte then we will have to cut our energy consumption or pay a lot more for an already over priced electric bill. American consumers have proven their reluctance to support either of the aforementioned practices. As a matter of convenience, nuclear it is.
