This article introduces and overviews U.S. renewable energy policy. It describes the shape, content, and contours of that policy, including its emphases and functions in both the electricity and transportation sectors of the U.S. economy. To do so, the article builds a conceptual model that can...

Since emerging as a capital destination in the late 1990s, the experience of venture capital (VC) in clean energy technologies (CET) has been checkered. Haphazard investment activity in the early 2000s paired with high-profile failures of once-promising CET ventures to produce a general...

In what format and under what timeframe China would take on climate commitments is of significant relevance to China because it is facing great pressure both inside and outside international climate negotiations to exhibit greater ambition and is being confronted with the threats of trade...

China had been the world's second largest carbon emitter for years. However, recent studies show that China had overtaken the US as the world's largest emitter in 2007. This has put China on the spotlight, just at a time when the world community starts negotiating a post-Kyoto climate regime...

Renewable portfolio standards (RPS) are the most popular U.S. state-level policies for promoting deployment of renewable electricity (RES-E). While several econometric studies have estimated the effect of RPS on in-state RES-E deployment, results are contradictory. We reconcile these studies and...

The diffusion of renewable energy in the power system implies high supply variability. Lacking economically viable storage options, renewable energy integration has so far been possible thanks to the presence of fast-reacting mid-merit fossil-based technologies, which act as back-up capacity....

There is a large gap between the percentage of electricity generated from renewable sources in the U.S. and EU. This paper argues the reasons are not just a failure of policy in the U.S. but also matters of deep political structure and culture. Federalism, separation of powers, changing policies...

Given that China is already the world’s largest carbon emitter and its emissions continue to rise rapidly in line with its industrialization and urbanization, there is no disagreement that China eventually needs to take on binding greenhouse gas emissions caps. However, the key challenges are...

Climate change mitigation relies increasingly on clean technologies such as renewable energy. Despite widespread success, further deployment of renewables has been met with resistance from voters and governments in several countries. How resilient is the renewable energy industry to adverse...

Environmental policy is increasingly concerned with measuring emissions resulting from local changes to electricity consumption. These marginal emissions are challenging to measure because electricity grids encompass multiple locations and the information available to identify the effect of each...
