Renewable energy tops nuclear power in the US By John Timmer
Plunging prices and booming investments are beginning to reshape the energy market, according to a couple of reports that were released this week. A report produced on behalf of Bloomberg says that investments in renewable energy have gone up by roughly a third over the last year, to $211 billion. Led by China's renewable push, the world is now on a trajectory that will see its investments in renewable electricity surpass those in fossil fuels within a year or two. As a result of these investments, the US is now producing more renewable energy than nuclear power.
First, renewable investments. Bloomberg's New Energy Finance group has collaborated with the UN Environment Programme and the Frankfurt School of Finance and Management to produce a global overview of funding for renewable power. This includes the obvious—financing for the construction of utility-scale projects and home installations—and some non-obvious funding, like merger and acquisition activity.
Any way you look at things, the numbers make it clear just how significant renewables have become. Excluding hydropower, renewables made up about 35 percent of the power capacity added worldwide last year, and produced over five percent of the total power. Investments directed toward this new capacity (excluding things like mergers) hit $187 billion, and are closing in fast on the spending on fossil fuel power plants, cutting the gap in spending to $31 billion, down from $74 billion. At that pace, we'll be investing more in renewables either this year or next.

Part of the reason is cost. Although wind turbines are very mature technology now, their cost per MW still fell by 18 percent over the last two years; photovoltaics have dropped a staggering 60 percent in that time. "Further improvements in the levelised cost of energy for solar, wind and other technologies lie ahead, posing a bigger and bigger threat to the dominance of fossil-fuel generation sources in the next few years," according to the report's authors.
That will be a major transition...
