" We have three choices if we wish to keep on increasing global energy consumption while minimizing the risks of anthropogenic climate change due to rising combustion of fossil fuels and keeping atmospheric levels of greenhouse gases from rising to as much as three times their pre-industrial level: we can continue burning fossil fuels but deploy effective methods of sequestering the generated CO2, we can revive the nuclear option, or we can turn increasingly to renewable energy. None of these options is yet ready to take over from fossil fuels on requisite scales, none could be the sole near-term solution, and all have their share of economic, social, and environmental problems "
