The transition to a low carbon economy is irresistible and energy remains at the heart of global climate change solutions. Effective renewable energy policy is absolutely crucial in shaping competitive and attractive markets. However, energy markets are highly complex, living systems that involve a variety of technologies spanning a wide range of technical and economic maturity. Each market is unique so there is no one-size-fits-all policy formula that can put the global power system on a firmer path to the low carbon economy. “A Primer on Climate Change and Renewable Energy Policies and Regulations” takes a pragmatic look at the available choices and evaluates the mechanisms, key considerations, pros and cons, and examples of what worked and what did not and why.
