This paper presents high renewable electricity penetration scenarios in the United States using detailed capacity expansion modeling that is designed to properly account for the variability and uncertainty of wind and solar resources. The scenarios focus solely on the electricity system, an...

Recent work found that renewable energy could supply 80% of electricity demand in the contiguous United States in 2050 at the hourly level. This paper explores some of the implications of achieving such high levels of renewable electricity for supply chains and the environment in scenarios with...

We provide a meta-analysis of several recent analytical studies that evaluate the possibility, operability, and implications of high levels of renewable sources of electricity (RES-E) in power systems. These studies span different geographic regions, rely on a range of analytical methods and...

The United States power sector is being transformed by the recent rise in the availability and use of unconventional natural gas, specifically shale gas. That transformation has already produced some of the most significant changes in the operation of the portfolio of electricity generation...

Although emerging technologies like carbon capture and storage and advanced nuclear are expected to play leading roles in greenhouse gas mitigation efforts, many engineering and policy-related uncertainties will influence their deployment. Capital-intensive infrastructure decisions depend on...

Modelling price formation in electricity markets is a notoriously difficult process, due to physical constraints on electricity generation and transmission, and the potential for market power. This difficulty has inspired the recent development of bottom-up agent-based algorithmic learning...

In this article the growing popularity of economic value added (EVA) is addressed. It discusses why managers are turning to EVA as a performance metric, how EVA is used by companies, and the problems that typically arise in implementing it. The accounts of Rhône-Poulenc are used to demonstrate...
