Globally as well as in China, cities have contributed to most of the economic output and have accordingly given rise to most CO2 emissions. In particular, given unprecedented urbanization, cities will play an even greater role in shaping energy demand and CO2 emissions. Therefore, cities are the...

China's rampant environmental pollution problems and rising greenhouse gas emissions and the resulting climate change are undermining its long-term economic growth. China, from its own perspective cannot afford to and, from an international perspective, is not meant to continue on the...

Rapid decarbonization of whole countries requires additional research, development, and demonstration of low-carbon energy technologies. Governments support research, development, and demonstration in this area with various financing instruments. These instruments are frequently assessed by...

China and India will have to radically transform their electric power systems in order to decouple economic growth from unsustainable resource consumption. While the majority of transition literature has focused on the diverse socio-technical factors that could enable such a transformation, more...

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...

We fit CES and VES production functions to data from a numerical bottom-up optimization model of electricity supply with clean and dirty inputs. This approach allows for studying high shares of clean energy not observable today and for isolating mechanisms that impact the elasticity of...

The transition towards low-carbon economies requires massive investments into renewable energies, which are commonly supported through regulatory frameworks. Yet, governments can have incentives - and the ability - to deviate from previously-announced support once those investments have been...

The costs of renewable energy technologies have fallen sharply. Now the financing costs of new installations are playing an increasing role in the overall cost of Germany’s energy transition. This has put the primary focus of support instruments for renewable energy on creating more affordable...

Power systems with increasing shares of wind and solar power generation have higher capital and lower operational costs than traditional technologies. This increases the importance of the cost of finance for total system cost. We quantify how renewable policy design can influence cost of finance...
