Despite being a reliable, zero-emissions alternative to energy derived from fossil fuels, nuclear energy remains mired in controversy.Opponents often cite four reasons not to include nuclear in the portfolio of alternative energy sources that will replace fossil fuels: its cost, what to do with radioactive waste, the increased risk of nuclear weapons proliferation, and environment and health impacts resulting from accidents or meltdowns.But how are these risks quantified and how do they compare to other energy sources, including carbon-intensive energy? As the climate crisis worsens, can we really afford to exclude nuclear from the list of solutions?Dr. David Keith, internationally-recognized climate and energy scientist and entrepreneur out of Harvard University, helps us understand how the risks of employing nuclear compare to the risks of not using it.Follow us on Twitter, LinkedIn, Facebook, and Instagram.Contact us at contact@climatenow.comVisit our website for all of our content and sources for each episode.
