Energy abundance means that many of civilization's bottlenecks have started to disappear. Among others, large scale desalination and hydrogen production are no longer issues. Access to space is also relatively inexpensive. If a big problem demands a lot of power to solve, solving it is not going to be a big problem.
Between renewables, fusion, superbatteries, supercapacitors, and superconductors, energy is abundant and inexpensive. Many people generate most of their own power. This has helped dramatically reduce political tensions over fresh water and get commuter space flight on the table. Private space exploration includes several bases on the Moon with a few thousand people, two Mars bases (one dead, one struggling but working), and three corporations mining asteroids.
