Yes, and all the paper straws in the world isn't going to save it, between wars, attacks on critical infrastructure and AI overlords.

All this new scalable renewable energy sources such as solar and wind (biomass is not scalable and hydro, geothermal depend on geology) are not cheap enough to compete with fossil fuels for industrial applications. Energy not electricity. 1 GJ of heat from coal is still cheaper than 1 GJ of electicity from solar, especially when needed 24/7.

There many countries in the global south with large populations which want to grow and don't have enough energy

We need very cheap nuclear power not only for electricity, but also for heating, water desalination, hydrogen production, CO2 capture.

Nuclear is indeed the answer. Nuclear power is incredibly safe nowadays and it also provides kinetic inertia, something that solar and wind power lack (they are all DC based and only produce AC when using an inverter, which is wasteful too).

Unfortunately I think it's already too late for nuclear. People who don't understand energy grids are voting for anti-nuclear policies, with very predictable results.

Nuclear costs far more per kWh than solar/Wind plus storage

Yes we need lots more electric. Nuclear isn’t the answer.
