In his Spring Oppenheim Lecture on March 31, Dan Kammen talked about if and how we can achieve a low-carbon/no-carbon economy. He stated that reducing greenhouse gases by the levels required will be a monumental undertaking, one that requires an aggressive mixture of science, technology and policy. He noted that there are number of 'high impact' innovations that are specifically needed to alter our energy system. He examined a number of these tipping points in the energy system, with examples and applications drawn from the US, Portugal, China, Nicaragua, and east Africa.
