Amory Lovins, long time anti-nuclear power advocate: As the Italian proverb says, arithmetic is not an opinion. So let’s do the math. Renewables and efficiency cost less than operating many nuclear plants. That's right, arithmetic is not an opinion, but garbage numbers and unsound assumptions into the arithmetic leads to worthless numbers out. Same for computer models for climate science. "Efficiency," code for using less energy, obviously costs less than producing energy. The public listens to what they want to hear. So his article, celebrating the agreement with Friends of the Earth and the Natural Resources Defense Council to close the last operating nuclear power plant in California will be music to anti-nuclear power advocates and a sad tragedy for most of humanity and the environment. Lovins talks about "carbon" not carbon dioxide. Carbon is diamonds. Carbon dioxide is a colorless, oderless gas that is essential for all life! So he wants to do the math!!

Euan Mearns, geologist: It is important to recall that well over $1,700,000,000,000 ($1.7 trillion) has been spent on installing wind and solar devices in recent years with the sole objective of reducing global CO2 emissions. It transpires that since 1995 low carbon energy sources (nuclear, hydro and other renewables) share of global energy consumption has not changed at all. New renewables have not even replaced lost nuclear generating capacity since 1999. ZERO CO2 has been abated and the world has done zilch to prepare itself for the expected declines (escalating costs) of fossil fuels in the decades ahead. If this is not total policy failure, what is?

Ferruccio Ferroni, Dipl. Ing. ETH, Theo Schaub, Dipl. Ing. In der Schweiz ist der Begriff Nachhaltigkeit in der Bundesverfassung, Art. 73 wie folgt umschrieben: „Bund und Kantone streben ein auf Dauer ausgewogenes Verhältnis zwischen der Natur und ihrer Erneuerungsfähigkeit einerseits und ihrer Beanspruchung durch den Menschen anderseits an.“ Auf die Prozesse der Energieumwandlung angewandt heisst dies nichts anderes, als dass man der Natur nicht mehr Energie entnehmen soll, als man nach der Umwandlung gewinnt. Bei einer Nutzenergie von 2300 kWh/m2 und einem Erzeugungsaufwand von 3000 kWh/m2 ergibt sich klar eine negative Energiebilanz.

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.
