Bonne Posma, physicist, Chairman, Nuclear Africa (Pty) Ltd, Founder, Saminco (USA) specializing in electric propulsion systems for off-road vehicles and underground mining conveyances. Comments by John Droz, physicist, Jon Boone, wind energy expert, Eric Jelinski nuclear and wind energy expert: Newly elected leaders in South Africa are changing the energy plan now aiming to use massive amounts of wind and solar energy instead of additional nuclear power. South Africa is unique in the world in having outstanding experience with nuclear power and production of radioisotopes for nuclear medicine. it has some of the world's top experts in nuclear energy. This paper discusses the technical consequences of using wind and solar instead of nuclear. South Africa will squander the expertise they have that can help all of Africa. Political and business lobbying with elected officials will have terrible consequences, when elected officials don't care to understand the technologies they are deciding on.

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.

Praveen Duddu: Eight of the 10 largest wind farms in the world are operated in the US, with five situated in Texas alone. Just one offshore wind farm has made to the list, while all others are onshore. Power-technology.com profiles the world's 10 largest wind farms based on installed capacity.

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”.
