Economic evaluation of green or renewable power should compare the cost of renewable power with the cost savings from displaced fossil generation plus the avoided harm from reduced emissions of air pollution and greenhouse gases. We use existing estimates of the values of the harm and we...

To decarbonize the power sector, policy-makers need to commit to long-term credible rules for climate and energy policy. Otherwise, risk of opportunistic policy-making will impair investments into low-carbon technologies. However, the future benefits and costs of decarbonization are subject to...

All forms of renewable energy are at an inflection point. Falling costs, changing technology, and new environmental and climate regulations have all moved to exponentially increase the growth of renewable energy. How legal terms, such as "qualifying facility" under PURPA are interpreted and...

This report investigates the effects of select climate policies, non-climate policies, as well as political economy factors on the decarbonisation of electricity in OECD countries from 2000 to 2015. Effects are analysed on the three phases of decarbonisation: (1) increasing the share of...
