Dr. Ryan H. Wiser is a Senior Scientist and Deputy Group Leader in the Electricity Markets and Policy Group at Lawrence Berkeley National Laboratory. Ryan leads and conducts research and analysis on renewable energy, including on the planning, design, and evaluation of renewable energy policies; on the costs, benefits, and market potential of renewable electricity sources; on electric grid operations and infrastructure impacts; and on public acceptance and deployment barriers. His recent analytic work has included studies on the economics of wind and solar power; the impacts of higher penetrations of renewable energy on the electricity sector; the design of renewable energy promotion policies; the risk mitigation value of renewable electricity; the treatment of low-carbon supply options in utility resource planning; and community acceptance of wind and solar power. The Electricity Markets and Policy Group (EMP) of the Lawrence Berkeley National Lab conducts technical, economic, and policy analysis of energy topics centered on the U.S. electricity sector. Our current research seeks to inform public and private decision-making on public-interest issues related to energy efficiency and demand response, renewable energy, electricity resource and transmission planning, and electricity reliability.
