Some have argued that it is feasible to meet all of our energy needs with renewables. The 100% renewable scenarios downplay or ignore the intermittency issue by making unrealistic technical assumptions, and can contain high levels of biomass and hydroelectric power at the expense of true sustainability. Large amounts of nuclear power would make it much easier for solar and wind to close the energy gap.

Throwing tools such as nuclear out of the box constrains humanity’s options and makes climate mitigation more likely to fail. We urge an all-of-the-above approach that includes increased investment in renewables combined with an accelerated deployment of new nuclear reactors. (...) »
