- Abstract - So much work is underway to advance energy technologies to make them more efficient, have a lower carbon footprint, more accessible to communities, and so forth. And yet, it is so hard to put new energy technologies into place in domestic (and many international) markets. Why is that? Tierney discusses the array of factors arising out of national energy policy, regulatory approaches and practices, energy and other politics, investment settings, and so forth, that create tenacious barriers to the introduction of advanced energy technologies into existing systems. She also will address what is happening to overcome those obstacles and why more is needed. - About the Speaker - Sue Tierney, a Managing Principal at Analysis Group in Boston, is an expert on energy economics, regulation and policy.
