The "Galactic-Scale Energy" post is a great illustration that a constant percentage growth rate eventually hits hard limits imposed by physics. Posts like abetusk's are a great illustration that "the solar budget" is a very generous energy budget. That may seem too obvious to mention, but in 20th century ecology literature (or even as recently as the early 2010s) living within "the solar budget" was often conflated with a low-energy, deindustrialized future. Constant growth fueled by sunlight (or anything else) can't go on indefinitely, but there's also no prospect that a sunlight-fueled world would have less energy available than the old fossil-fueled one.
