By Stephen Lacey on Jul 14, 2011 at 8:37 am Each day, the Energy Information Administration releases a slice of data from its archives illustrating the state of the U.S. energy market. It’s a helpful and often fun resource for anyone who likes energy data. (It can also be a downer, as the charts often show how far we have to go to scale non-hydro renewables.) This chart, showing historic capacity additions to the U.S. electrical mix, is a case in point. To the optimist, it shows the beginning of a massive shift, with wind taking a huge slice of new power plant build-out in the last six years. From 2005 to 2009, wind represented about 35% of installed capacity, and in 2010 represented $11 billion in investment and 25% of new capacity additions. As we saw with hydro in the 40's, coal in the 50's and nuclear in the 70's, we’re realizing the beginning of a new era in energy. But the pessimist may ask: “Where’s everything else?” Indeed, there’s a notable lack of “other,” meaning solar PV, small hydro, geothermal and biomass. The fastest growing sector, solar PV, will put about 2 GW of capacity online in the U.S. this year — very large compared to historic growth, but still small in this context. Small hydro is bogged down in regulatory red tape, new geothermal build-out is moving slowly due to technical and financing issues, and concerns about emissions slowed biomass generation. And all of these resources are suffering from a lack of long-term certainty on the federal level. And, of course, many renewables, like wind power, provide power for less time in a given day than many traditional plants, so their share of total delivered electricity is less than their share of capacity. One wonders what this chart will look like a decade from now. We can only hope it has a lot more color on it.thinkprogress.org
