Representatives of the public, private, and academic sectors will discuss gaps and other deficiencies in policy that are hindering expansion of wind and solar energy in the United States, with reference to policies in other countries that support expansion of these weather-dependent energy systems. Panelists will address such as the following: What has been the effect of the PTC and its extensions on annual timescales, and should it be extended again? What policies in Europe, Canada, and other countries support faster growth of wind and solar power? What are key components of any future, U.S. energy policy to encourage a sustainable energy system? How will the weather and climate enterprise contribute to the nation’s energy system in the future?
