According to Lazard, the most cost-effective options to reduce carbon emissions are wind and utility-scale solar. Rooftop solar might fit there, except that Lazard found that the cost of installing rooftop solar in the U.S. runs twice that of the rest of the world.

It’s a truism perhaps most prevalent in the music scene: today’s alternative is tomorrow’s mainstream.

I remember when a new Irish band called U2 first came to the United States. Their first show was at a Washington club called The Bayou, where my band frequently played. U2 was opening for some good friends of mine, the locally-hot Slickee Boys. Afterwards, the Irish kids went off on their American tour in support of their just-released first album, Boy. I Will Follow from the album became a monster hit on alternative radio (mainstream rock radio at the time wouldn’t touch it). But the buzz in the indy media was strong enough so that when U2 came back to the Bayou for their final U.S. show of the tour, The Slickee Boys opened for them. And a local rock radio station carried the concert live. U2 never looked back, becoming for years one of the (some might argue “the”) biggest rock bands in the world.

There are surely similar stories out there about Nirvana and Pearl Jam, and most every other initially indie music act that hit it big. And there are probably stories about other arenas–film, literature, whatever.

The concept seems to work for energy too.

Back in the day–ok, even five years ago–solar and wind power were often described as “alternatives.” Alternatives to coal, or nuclear, or whatever energy source they were being compared to. Hell, even NIRS’ own website still has a section focused on renewables and efficiency labeled Alternatives to Nuclear. The implication of being an “alternative” is that it isn’t quite mainstream yet, perhaps not yet ready for the big time.

If that’s the case, perhaps the Nuclear Energy Institute should set up a new section promoting nuclear power on its website titled Alternatives to Clean Energy. Because clean energy is now the mainstream and the electricity production sources of the 20th century are, at most, alternatives. To be sure, though, they are obsolete alternatives.

Last week, the International Energy Agency (IEA) pointed out that renewables are now the second largest generation source in the world, topped only by coal, and that renewables accounted for half of all new generation in 2014.

But more forward-looking–and even more compelling–is a report released yesterday from the investment bank Lazard, which examines the levelized costs of the various energy technologies. Wind and solar are not only beating nuclear–as would be expected–but also coal and even natural gas. Remember that next time you read about some utility exec (or uninformed journalist) complaining that nuclear reactors are closing because of competition from low-priced gas. Sure, the ready availability of gas right now due to large-scale fracking means there is ample supply at low cost–but the real competition on the price end from …read more
