Elizabeth Cook Rostermundt's three month bicycle tour of Europe in the 1950s was an amazing discovery for a young American and an interesting view of history only about ten years after the most horrific war of all time, WW II. We post this story mainly because it points to recovery from massive war crimes and tremendous suffering and on to making a better world. It is the story of a young woman who was not close to the suffering as she enjoyed the beauty and people of Europe on the road to recovery.
Euan Mearns, Geologist, Ferruccio Ferroni, Energy Consultant, Robert Hopkirk, Engineering Research & Development, Switzerland: Euan Mearns (UK) presents the paper by Ferrucio Ferroni and Robert Hopkirk (Switzerland) about energy return on energy invested for solar photovoltaic energy used in Switzerland, Germany and the United Kingdom. Euan Mearns engages blogers on his website who are confident that they are more qualified than F. Ferroni and R. Hopkirk in Switzerland in knowing about solar PV energy. There are three kinds of learning science: a) the science sources themselves, b) the science sources with students in a classroom, and c) the science sources and "bloggers" on the Internet. We encourage everyone to learn and decide for yourselves. Switzerland has many fine scientists and engineers, no matter what these bloggers say. Starting with Paracelsus in the early 1500s, to Albert Einstein in the early 1900s and today's engineers and scientists in nuclear energy and nuclear science.
Ferruccio Ferroni, Energy Consultant, Robert Hopkirk, Engineering Research & Development, Switzerland: Photovoltaic power sources in regions of moderate insolation are analyzed using the concept of Energy Return on Energy Invested (ERoEI or EROI. The results for regions of moderate insolation levels such as Switzerland and Germany indicate that at today's state of development, PV technology cannot offer an energy source but a NET ENERGY LOSS. Our advanced societies can only continue to develop if a surplus of energy is available, but it has become clear that photovoltaic energy at least will not help in any way to replace fossil fuels.
Daniel Wetzel, Die Welt: A Greenpeace study reveals what the feted Paris Climate Agreement implies for the German public. If implemented, Germany will be unrecognizable in a few years. Rural residents and their children will have to mentally prepare for an increase in the next few years from 26,000 wind turbines today to 80,000 rotor towers, if the study correctly describes how to achieve the climate targets agreed in Paris.
