If you speak spanish there's a really good book doing now the rounds by an skeptic of the long-term economical viability of renewables (and fossil fuels, nuclear, and more): Petrocalipsis, by Antonio Turiel. It's very clear, concise and data-driven, so it's one of those books where even when you disagree with a point it forces you to research why.

An ok alternative in english would be Facing the Anthropocene, by Ian Angus (but the scope of that book is way more limited, and it's markedly political, specifically ecosocialist)
