Steven Lyazi, Ugandan leader for better economy, government, medicine and energy for Uganda and Africa, Member of Board of Advisors for Environmentalists for Nuclear - USA, website: efn-usa.org: Africa has some big dreams. One is a Trans East Africa railway that will link Uganda, South Sudan, Kenya, Tanzania, Burundi, Rwanda and Horn of Africa countries. This will be a first of its kind electric railway, some 750 kilometers (466 miles) long, and it will need tremendous amounts of energy that cannot come from wind turbines and solar panels. It will have to come from nuclear power plants – or coal or natural gas generating plants. Africa has these resources in great abundance. But so far we are barely developing or using them, except maybe to export oil to wealthy nations.

Jean-Luc Salanave, Le développementfulgurantdes énergies solaire, photovoltaïque etéolienne,en ce débutde XXIe siècle, nous faitaussi expérimenter leurs inconvénients.La technologie en solutionnera bon nombre,mais intermittence etencombrementdemeurerontdes défauts majeurs de ces deux sources d’énergie tantqu’il y aura des absences de soleil ou de vent,etque 10 milliards de terriens auront besoin de surfaces habitables,cultivables etde forêts. Conclusion Pour satisfaire ses besoins énergétiques,l’homme ne disposera de rien d’autre que des trois seules forces fondamentales que la nature metà sa disposition :la force électromagnétique (énergies chimiques,combustibles fossiles,biomasse,photovoltaïque,…),la gravitation (énergies hydraulique,éolienne,inertielle,potentielle …) et les forces nucléaires (radioactivité,fission,fusion).

Friedrich Wagner: Germany decided to go nuclear-free by 2022. A CO2-emission-free electricity supply system based on intermittent sources, such as wind and solar - or photovoltaic (PV) - power could replace nuclear power. Intermittent sources are, by definition, unsteady. Therefore, a back-up system capable of providing power at a level of 89% of peak load would be needed. This requires creating an oversised power system to produce large amounts of surplus energy. A day storage to handle surplus is ineffective because of the day-night correlation of surplus power in the winter.

Paul Driessen reviews Pope Francis' address to the US Congress and encyclical, Laudato Si ("Praise Be to You" concerning use of fossil fuels, the topic of catastrophic man-made global warming, poverty and the environment. Driessen concludes, "Absolutely, let us have a real, open, robust conversation about these issues. And let us include everyone in it, because the energy, environmental and human rights challenges concern and affect us all."
