"It is entertaining to muse about what we might not have today if fossil fuels had never been available or utilized. Would we have computers or lasers? Would we have skyscrapers or photovoltaics? Would we have understood nuclear energy or fundamental physics that relied on high-energy experiments? Would we even have bicycles? It is, of course, impossible to say with any certainty. But since all of these things first emerged after fossil fuels took hold, and built upon each other in ways that at least had access to the benefits of fossil fuels, it is plausible that most of what we see around us in the developed world owes its existence to fossil fuels. In fact, one might say that it is a much tougher case to argue the counterfactual that we would still have comparable technology today had fossil fuels not burst onto the scene."
