The myths and assumed wisdom around renewable energy and its capabilities have been refuted, time and time again, by renewable energy scientists and engineers, but despite this, incorrect and misleading assertions are repeated, as if repetition of a falsehood somehow makes it true.
And who are the people peddling these inaccuracies? They come mainly from the coal and nuclear industries, electricity generators, other big greenhouse polluters such as the aluminium industry, and the supporters of these industries. And with the exception of some nuclear power proponents, renewable energy deniers are generally also climate change deniers.
If they cannot refute a particular observation by rational argument, they try to cast doubt on the result by introducing irrelevant material. They look for molehills in renewable energy systems and blow them up to mountains. They are masters of the 10% truths: taking a few facts and then spinning them into stories that convey the opposite impression from the logical implications of those facts. They insinuate arguments rather than state them clearly and unambiguously. Then, when questioned incisively about their insinuations, they back off and shift ground.
