In this episode we meet Kevin Anderson, professor of Climate and Energy at the University of Manchester. Kevin talks about the widespread illusion that we can mitigate climate change within business as usual, small steps and some future technology. Instead the understanding that we have a carbon budget forces us to reduce the emissions of CO2 with about 10% per year, starting now.
He concludes that we have the scientific knowledge and technical solutions to move to renewable energy, but we lack the political, economical and cultural will to implement the systems at scale.
He is endorses the research of so called ”negative emissions” and geo engineering, but does not want us become dependent upon them.
He works on climate questions because we still have a possibility to avoid catastrophe, but he thinks we are about to choose to fail. ”Let’s not pretend it is not a choice”.
The conversation took place in Stockholm, February 20, 2017.
James Hansen, most known for his engagement in climate science, gives his take on how to replace the fossil energy. In this video he gives a brief overview, but the main topic is nuclear energy.
Some remarks and comments:
– Many countries show by example how renewables can supply demand (Germany, Denmark, Scotland etc), thus it is unclear when he says renewables can’t provide enough energy.
– All countries does not have the same potential for renewable energy.
– Renewable can never replace coal or nuclear as base load power.
– He doesn’t say we should not use renewable. Just that we can’t provide all the energy we need with it.
– Being more efficient with energy just ain’t enough. As soon as someone uses less energy, someone else will burn it instead. We need to make the fossil energy more expensive with incentives in order to lower the demand and use.
Bill gates is mostly known for two things: Microsoft and funding of health care.
Here, on this TED-talk, he takes on the great task och climate change and energy.
