This comparison is misguided: the uncertainties around these values mean they are likely to overlap. The key insight is that they are all much, much safer than fossil fuels. Nuclear energy, for example, results in 99.9% fewer deaths than brown coal; 99.8% fewer than coal; 99.7% fewer than oil; and 97.6% fewer than gas.
For the storage of the energy generated, there are only the following three options: batteries, fuel cells, and supercapacitors. Now supercapacitors are considered the best energy storage option. Supercapacitors have more capabilities than conventional capacitors and secondary ion batteries [22,23].
