Hansen on renewable energy
What about renewable energy?
James Hansen: I think it’s unfortunate that so many environmentalists are just assuming that these renewables will be able to satisfy all of our requirements. Renewables, the ‘soft renewables’, are only providing between one and two percent. Hydropower provides a significant amount of electricity. But that’s limited as to how much of that we can have. The hope that sun and wind and geothermal can provide all of our energy is a nice idea, but I find it unlikely that that is possible. The environmental community is basically asking the governments to reduce their emissions and subsidizing clean energy. Well, that simply doesn’t work, we don’t get enough energy from renewables to make a difference. That then forces any government to approve expanded oil drilling, hydro fracking to get more gas, mountain top removal to get more coal… We’re not going to turn the lights out. No government, no president, no governor is going to turn out the light, there has to be energy. And if renewables are not providing it, then it’s fossil fuels.
