At the Asian Development Bank annual meeting this week, Jeffrey Sachs, director of the Earth Institute and professor of sustainable development at Columbia University in the US, said: “We won’t meet the carbon targets if nuclear is taken off the table,” and further: “Emissions per unit of energy need to fall by a factor of six. That means electrifying everything that can be electrified and then making electricity largely carbon-free. It requires renewable energy, nuclear and carbon capture and storage – these are all very big challenges. We need to understand the scale of the challenge.”
Energy in Demand - Sustainable Energy - Rod Janssen 
Jeffrey Sachs is wrong again: CCS nor nuclear offer any hope of alleviating the carbon burden. CCS is an expensive pipe dream designed to extend the life of the fossil fuel industry, and nuclear power too small, expensive and toxic to even warrant a serious thought. Neither attract any private sector investment, and both serve to slow the shift to a renewable world. Renewable energy, combined with efficiency and sufficiency measures is more than capable of meeting demand – and nurturing innovation and building prosperity in the process.
