Evidence based science

When we look at the countries which are hardly using any fossil fuels for electricity generation, there is one thing in common.

Their main source of electricity comes from hydro and/or nuclear power plants.

Their grid might contain some wind, geothermal and pelleted forests (aka. biomass), but those sources are only a fraction of their generation.

The main reason we do not see any country running on solar and wind alone, is that those sources are highly intermittent in another word, they are unreliable.
When the sun goes down and the wind stops, we still want to have electricity.
There are two solutions for this issue:

  • Storage
    which is difficult and expensive
  • Burn fossil gas
    easy and affordable

Guess which of the two most country chooses…
We need a miracle in electricity storage technologies to be able to run on chaotic energy sources like the weather, otherwise we just reduce but not replace fossil fuel usage.

As long as cheap electricity storage is not available, our best bet is hydro and geothermal for those countries where the geology allows it and nuclear for the rest.

TL;DR

Being a truant, blocking highways, damaging art, gluing yourself to a wall/table/floor can get you the attention but will not solve anything.

Humans are a weak tropical species. Our thermal comfort lays between 19°C and 27°C. Prolonged exposure to the elements and lack of thermal control will kill us much faster than a shortage of food or water. We become the apex predator of this planet by using extra energy. If we want to keep 95%+ of Earth’s population alive, we need energy. A lot of it.

The problem is, that our energy need grown so much, that it is influencing the climate by emitting green house gases as a side effect.
We a sustainable energy source, which

  • Uses the least amount of land per unit of energy
  • Emits the least amount of green house gasses per unit of energy
  • Has the least amount of raw material needed per unit of energy
  • Provides the highest energy return on energy invested
  • Reliable, therefore does not need fossil fuel backup
  • Can be built in almost every country

There is only one energy source, which can tick all the above boxes is nuclear.
