U.S. Secretary of Energy Rick Perry in April requested a study to assess the effect of renewable energy policies on nuclear and coal-fired power plants. ![]()
Some energy analysts responded with confusion, as the subject has been extensively studied by grid operators and the Department of Energy’s own national labs. Others were more critical, saying the intent of the review is to favor the use of nuclear and coal over renewable sources.
So, are wind and solar killing coal and nuclear? Yes, but not by themselves and not for the reasons most people think. Are wind and solar killing grid reliability? No, not where the grid’s technology and regulations have been modernized. In those places, overall grid operation has improved, not worsened.
To understand why, we need to trace the path of electrons from the wall socket back to power generators and the markets and policies that dictate that flow. As energy scholars based in Texas – the national leader in wind – we’ve seen these dynamics play out over the past decade, including when Perry was governor.


A joint research effort from Rice University and Kazan Federal University is demonstrating a new way to pull radioactive elements out of contaminated water. The researchers behind this study believe their results could go a long way in purifying the hundreds of millions of gallons of water that were contaminated after the Fukushima nuclear plant accident.
Many scientists believe we’re at the tipping point of our energy technology future. With the advancement of new, alternative energy sources, some are left to wonder what will happen to the energy landscape as a whole.
