The “Dazzling Dozen” is not just a clever name for the twelve states that are leading the way in solar photovoltaic installations; they are an example to be followed in the move from fossil fuels towards a renewable energy utility of the future. On July 23rd, 2013, Environment America Research and Policy Center released a report, “Lighting the Way: What We Can Learn from America’s Top 12 Solar States,” describing the benefits of solar energy and some of the related policies.
The Dazzling Dozen are ranked by the highest per capita solar electricity capacity, and include the states of Arizona, Nevada, Hawaii, New Jersey, New Mexico, California, Delaware, Colorado, Vermont, Massachusetts, North Carolina, and Maryland. Arizona ranked first, producing 167 Watts per person of solar electricity, while Colorado ranked eighth, producing 52 Watts per person. These twelve states account for only 28% of the population, but 85% of installed solar photovoltaic systems in the United States.

A good short profile of the city of Freiburg, Germany, and their many sustainability initiatives. Freiburg is a little more than double Boulder’s size — both in population and area, so it has a similar average population density. It’s also a university town with a strong tech sector locally. The whole city was re-built post WWII, but they chose to build it along the same lines as the old city, with a dense core, and well defined boundaries. Today about half of daily trips are done by foot or on bike, with another 20% on public transit. They have a local energy efficiency finance program, on top of the national one administered by KfW, and higher building efficiency standards than Germany as a whole. Half their electricity comes from combined heat and power facilities that also provide district heating and hot water. It seems like they’d be a good model city to compare Boulder to, and learn from.
The Union of Concerned Scientists has gone through the catalog of America’s coal plants, and found hundreds of mostly small, old, polluting, inefficient generating units that just aren’t worth operating any more, even on a purely economic basis. They looked at several different sets of assumptions, including different natural gas prices going forward, a price on carbon, whether or not the competing natural gas fired generation would need to built new, or whether it existed already with its capital costs paid off, and whether or not the production tax credit for wind ends up being renewed. In all of the scenarios considered, they found substantial coal fired generation that should be shut down on purely economic grounds, above and beyond the 288 generating units that are already slated for retirement in the next few years. They also found that some companies — especially those in traditionally regulated monopoly utility markets in the Southeast — are particularly reluctant to retire uneconomic plants, and suggest this may be because they can effectively pass on their costs to ratepayers, who remain none the wiser.
