Another example of how nuclear is being defined as a necessary component in future energy plans.
Some believe that with sufficient resources, scientists and entrepreneurs could pioneer a kind of storage that multiplies the current four-to-eight-hour period of power delivery several times over. States, cities and companies have put out a flood of 100% renewable or zero-emission plans, which count on development of technology that can store electricity for days or weeks. ... Yet energy storage could hit a wall if power companies aren't already moving to replace most nonrenewable generation with wind and solar. Few energy analysts say they believe long-term storage would serve the same purpose as nuclear, gas or coal plants that produce a constant stream of 'baseload' power."
