"We don't know exactly when out fossil fuels will run out... but by the end of the century, our oil and natural gas supplies will be virtually non-existent, and limited coal supplies will be restricted to only a handful of countries. ...We are at the peak of a remarkable two-hundred-year glitch in the history of civilization and are about to embark on the descent. The coming changes will be earth-shattering."

“Fixed energy limits have not limited the progress of nature.”

“I encourage people to look into the Transition Network.”

“To combat the problems we face, we need to swim against the tide, and not only the main tide of environmentally blind industrialists, but also the secondary current of efficiency-blind environmentalists.”

“Cellular systems, ecosystems, and civilizations are, at base, thermodynamic systems. ...The system uses energy, eventually releasing it as useless heat. ...there is one vital difference between natural systems and human systems: natural systems receive a fixed energy input that never varies. If we could set a strict limit on energy use, we could build a human system that is just as stable as an ecosystem.”

“It is too late to slow this runaway train down before it tumbles into the chasm.”

“We should stop subsidizing the fossil-fuel industries and instead provide subsidies for local and community energy projects.”
