As a non-executive chairman less is required of Shattuck, allowing him to shift his focus from many of the daily tasks associated with leading the company. Advocacy Spending much of his career in the energy industry after leaving Alex. Brown & Sons, much of Shattuck's advocacy centers around topics dealing with the future of electrical energy in the United States. One such major point of advocacy has been the deregulation of energy markets across the United States. While prior to the 1990s energy was largely distributed by government regulated monopolies, legislation in various states eventually led to competition between energy companies, thus forcing significant change in how energy companies distributed electricity. In 2010, Shattuck spoke before the US Chamber of Commerce:"We have markets now where the important thing is that people have choice...Twenty-two states have broken up their regulated utilities to permit competition, he said, and costs have come down. "Deregulated markets do what they are supposed to do...Monopolies are not going to be the answer in terms of driving efficiencies, driving costs down and driving innovation"Additionally, in contrast to many of his peers in the energy industry, Shattuck has been vocal in his support for a carbon tax stating,"We ought to address climate change, and address it through a price on carbon"In 2009, Shattuck released a statement on behalf of Constellation Energy backing a bill named the American Clean energy Security Act of 2009 which limited carbon emissions and promoted green energy generation. Lastly and most notably, Shattuck is an outspoken advocate for American nuclear energy. In particular, Shattuck argues for additional sovereign support in the form of extension of government loan guarantees in the construction of nuclear reactors. Speaking to a Johns Hopkins audience, he stated that"if that upfront fee is really big, it's going to discourage people from wanting to take the loan, because there's so much money going out for a plant of that size. It is a process that we're in to get all parties to get their arms around the gap analysis"During his time at Constellation Energy and Exelon, Shattuck served as chairman of the Institute of Nuclear Power Operations and a member of the Executive Committee of the Nuclear Energy Institute and Co-Chairman of the Commission on Nuclear Policy in the United States. After withdrawing from a joint project with EDF to operate nuclear plants in the United States, Shattuck continues to advocate
