After I published in "Cassandra's Legacy" a post titled "The renewable revolution" I was surprised at discovering that many of the commenters reacted negatively to it, taking for granted the fact that renewables, in the form of photovoltaics or wind, "have a low EROEI" and, as a consequence, are unable to exist without a subsidy from fossil fuels. This view has its origins in the 1990s, when it was commonplace to state that "A renewable plant cannot provide enough energy to repay the energy needed to build the plant." That is, the EROEI of renewables was supposed to be smaller than one.
Perhaps the "low EROEI" of renewables was true in the 1990s, but it is not true any longer.
