The inconvenient truth is that it is a theory, an opinon, a belief that has become an emotional and moralizing religion. It is the largest thinkable illusion that the world could decarbonize within 30-40 years, and therewith change the global climate. Climate change will not care a bit. Energy is physically not " renewable ", hence the nonsense term of " renewable energy " in order to make people believe that it is inherently good. It is no coincidence that the majority of the people do not fully understand that every windmill and every solar panel needs an expensive back-up capacity, that does not exist and is not economically affordable to build. I'll skip the commercial interests of the wind and solar industry in government guaranteed returns for 20 years. None of these installations have a useful life of more than 20 years. Every windmill needs to stand on 20-30 tons of concrete blocks, but no green concrete/cement exists. Alternative energy productions are supplemental, but never able to meet the base-load needs of industrial societies at economic terms. China, India, Russia, Arabia and ultimately Africa, at least 3/4 of the world population, will not decarbonize, since they cannot afford it. We are running out of money already, as the total indebtedness of industrial economies confirms. It is tantamount to economic rape to finance non-productive investments with public debt. We do need investments to protect ourselves and our livelihoods from the effects of climate change. We can hardly foreseee the weather for a month. Nobody can foresee the global climate for decades. We cannot foresee the solar activities or vulcanic eruptions either.
