I don't think we'll ever have enough energy, we'll always find ways to use more, on earth or elsewhere.

- kiba 3y agoI am pretty sure we'll run into the problem of too much heat long before we need more power.
- adrian_b 3y agoFusion will become usable only elsewhere, not on Earth. On Earth, fusion does not make sense unless it would provide more energy than the energy received from the Sun. However, if an amount of energy comparable to that received from the Sun would be produced by fusion, after being used, that energy would become heat, causing an even more dramatic climate change than what we are facing now. Fusion energy could be very useful, but only on spaceships or on planets/satellites/asteroids that are far from the Sun, and never on Earth. The same is true for nuclear fission energy. In the short term, it can be useful to replace power plants that use fossil fuels with nuclear fission reactors, but the total amount of energy produced by nuclear reactions can never become so great as what can be obtained by capturing directly or indirectly solar energy, without causing climate changes. The most important research direction should be for efficient methods of long-term high-capacity energy storage, e.g. in synthetic hydrocarbons or in flow batteries, and not in nuclear energy.
