The term "renewable" encompasses a wide diversity of energy resources with varying economics, technologies, end uses, scales, environmental impacts, availability, and depletability. For example, fully "renewable" resources are not depleted by human use, whereas "semi-renewable" resources must be properly managed to ensure long-term
READ MOREThis 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.
