Mike Conley and Tim Maloney: This is an excellent detailed, easy to follow analysis of Stanford University Professor of Civil Engineering, Mark Jacobson's claim that the world can acquire all the electrical energy it needs from wind turbines and solar panels. In short, Jacobson's claim is not achievable and a waste of money and time. What are the most important roles of the sun? 1) Heat the planet to livable conditions, 2) Evaporate ocean water, 3) Cause plants to grow and be the basis of the food chain, 4) Cause wind to bring the evaporated ocean water over the land and drop it as rain and snow. Electricity from wind and solar besides being unreliable and unpredictable is extremely dilute. As the authors clearly point out, replacing worn out solar panels on Jacobson's grand scheme would require tremendous amounts of replacement parts every day and the Earth doesn't have easy access to all these materials. The authors point the way with nuclear. Good reading for everyone.
James Conca, scientist in the field of earth and environmental sciences. Contributor to Forbes: Stanford University Professor Mark Jacobson is the prophet of a religion that claims the world can be fueled by 100% renewable energy. But other scientists better not question him or he’ll excommunicate you. And by excommunicate, I mean sue in court. Jacobson filed a $10 million libel suit in Washington, D.C. Superior Court against another scientist, Dr. Christopher Clack, who dared to criticize him.
Michel Gay: Les dommages collatéraux de l’intermittence des énergies renouvelables (éoliennes et panneaux photovoltaïques) dans le système électrique européen sont dénoncés par l’Académie des Sciences dans un rapport de janvier 2015. Cette institution souligne le manque de réalisme des objectifs de la loi de transition énergétique. Elle craint également que cette politique soit contre-productive.
Michael Shellenberger, Environmental Progress: This presents video talks by Michael Shellenberger, Founder - President of Environmental Progress. EP focuses on realistic, practical energy equality for people around the world as well as improving/protecting the environment through better living for people, better practices in all areas of the food industry, manufacturing, harvesting from oceans, preservation of wildlife habitat and wilderness. A significant strength of Environmental Progress is that they look for areas where their assumptions and policies can be improved and acknowledge mistakes. Many organizations settle on policies without being open to better ideas.
