Jeff Johnson, Chemical & Engineering News: The U.S. appears to be witnessing the slow death of nuclear power. Plants are aging out and retiring, and their place in the electricity marketplace is being captured by cheaper, simpler, and less controversial sources—particularly natural gas plants and renewable energy sources such as wind and solar.

Senator Lisa Murkowski, Alaska: As our nuclear leadership declines, we are simultaneously losing our ability to influence security and nonproliferation decisions. Taking our place — but not always sharing our views — are countries that could put world security interests at risk. After inventing commercial nuclear power, the U.S. has now clearly fallen behind. Yet we can still turn the tide and restore our influence, particularly if we pursue the development of advanced reactors.

Clinton Crackel, Co-Founder, Nuclear Fuels Reprocessing Coalition: According to the EIA, as of 2017 in the U.S., nuclear power on the utility scale has the highest average capacity factor (reliability, also stated as CF) of 92%, while geothermal is rated at 76.4% and coal is rated at 53.5%. The optimum CFs for wind, solar photovoltaic (PV) and concentrated solar power (CSP) are 36.7%, 27% and 21.8%, respectively.

Edgar Ocampo Tellez: • Decir que las fuentes renovables de energía son inagotables es falso: tienen limitantes técnicas, físicas, y problemas de intermitencia. • El aumento exponencial de consumo de energía es muy reciente. Surge después de la Segunda Guerra Mundial. En los últimos ocho mil años la humanidad estuvo conformada por menos de 300 millones de habitantes, pero hoy somos siete mil millones. El potencial renovable de nuestro territorio es de 44 terawatts de energía hidráulica, 87 de eólica, 200 de solar y 52 de geotérmica; en total, 400 terawatts hora anuales; pero nos faltarían 600 más. “Ése es el predicamento en el que se encuentra el modelo energético mexicano, y no es de fácil solución”.
