I don’t think the previous Dark Age that followed the collapse of Rome was quite the same as what we’re facing. That involved a profound and incremen… - James Howard Kunstler

An overwhelming majority of scientists who have looked into the matter agree that global warming is underway and is... caused by people burning fossil fuels. This is the meta-fact hovering over all the details. [...] In [mining and] burning so much [hydrocarbons in the form of] coal, oil, and gas [as fossil fuels] we've released [a fraction of] 460 million years of sequestered carbon into the atmosphere in a mere two hundred years. There are consequences for doing this. The trajectory of climate problems has gotten only more severe since I discussed the issue in The Long Emergency in 2005. Greenhouse gas emissions have exceeded predictions. The IPCC report expects a sea level rise of at least three feet [91 cm] […]; of NASA says... seventeen feet [5.18 m]. If that is the case, there would be no need to argue over the finer points of how many square miles in the Netherlands would be underwater... along with Bangladesh, many Pacific islands, most of Florida, and the Mississippi River Delta, Houston, Jacksonville, Key West, and thousands of other places.

The belief that “market economics” will automatically deliver a replacement for fossil fuels is a type of magical thinking like that of the cargo cults of the South Pacific.
This age-old tendency of humans to believe in magical deliverance and to wish for happy outcomes has been aggravated by the very technological triumphs that the oil age brought into existence. Technology itself has become a… supernatural force, one that has demonstrably delivered all kinds of miracles within the memory of many people now living […]. There's no question that technology has prolonged life spans, relieved misery, and made everyday life luxurious for a substantial lucky minority. […] A hopeful public, including leaders in business and politics, views the growing problem of oil depletion as a very straightforward engineering problem of exactly the kind that technology and human ingenuity have so successfully solved before, and it, therefore, seems reasonable to assume that the combination will prevail again. There are, however, several defects in this belief.
One is that we tend to confuse and conflate energy and technology. They go hand in hand, but they are not the same thing. The oil endowment was an extraordinary and singular occurrence of geology, allowing us to use [a fraction of] the stored energy of millions of years of sunlight. Once it's gone it will be gone forever. Technology is just the hardware and programming for running that fuel, …not the fuel itself. And technology is… bound to the laws of physics and thermodynamics […]. All of this is to say that much of our existing technology simply won't work without petroleum, and without the petroleum "platform" to work off, we may lack the tools to get beyond the current level of fossil-fuel-based technology. Another way of putting it is that we have an extremely narrow window of opportunity to make that happen. In the meantime, here are the problems with the various alternative fuels, based on what we know now.

Few dogs were around anymore. Some had been eaten during the hunger that followed the flu in the spring of that year. People didn't talk about it; it was so demoralizing.
