U.S. states split on nuclear power viability

Nuclear power comes with its own set of potential problems, especially radioactive waste that can remain dangerous for thousands of years.

As climate change pushes states in the U.S. to dramatically cut their use of fossil fuels, many are coming to the conclusion that solar, wind and other renewable power sources might not be enough to keep the lights on.

Nuclear power is emerging as an answer to fill the gap as states transition away from coal, oil and natural gas to reduce greenhouse gas emissions and stave off the worst effects of a warming planet. The renewed interest in nuclear comes as companies, including one started by Microsoft founder Bill Gates, are developing smaller, cheaper reactors that could supplement the power grid in communities across the U.S.

Nuclear power comes with its own set of potential problems, especially radioactive waste that can remain dangerous for thousands of years. But supporters say the risks can be minimized and that the energy source will be essential to stabilize power supplies as the world tries to move away from carbon dioxide-emitting fossil fuels.

Tennessee Valley Authority President and CEO Jeff Lyash puts it simply: You can’t significantly reduce carbon emissions without nuclear power.


“At this point in time, I don’t see a path that gets us there without preserving the existing fleet and building new nuclear,” Lyash said. “And that’s after having maximized the amount of solar we can build in the system.”

The TVA is a federally owned utility that provides electricity to seven states as the nation’s third largest electricity generator. It’s adding about 10,000 megawatts of solar capacity by 2035 — enough to power nearly 1 million homes annually — but also operates three nuclear plants and plans to test a small reactor in Oak Ridge, Tennessee. By 2050, it hopes to hit its goal of becoming net zero, which means the amount of greenhouse gases produced is no more than the amount removed from the atmosphere.

An Associated Press survey of the energy policies in all 50 states and the District of Columbia found that a strong majority — about two-thirds — say nuclear, in one fashion or another, will help take the place of fossil fuels. The momentum building behind nuclear power could lead to the first expansion of nuclear reactor construction in the U.S. in more than three decades.

Roughly one-third of the states and the District of Columbia responded to the AP’s survey by saying they have no plans to incorporate nuclear power in their green energy goals, instead leaning heavily on renewables. Energy officials in those states said their goals are achievable because of advances in energy storage using batteries, investments in the grid for high-voltage interstate transmission, energy efficiency efforts to reduce demand and power provided by hydroelectric dams.
