Yale Environment 360 has an interview with the CEO of NRG Energy, a fossil fuel based, nationwide independent power producer (IPP) that sells their 22GW of generation into the wholesale market. He’s bullish on solar PV, much less so on wind. No mention of solar thermal. He believes storage will be vehicle batteries. Net metering policies and pricing will be key to broad adoption. Given the lack of forecast energy demand increase, he sees different sources of energy (esp. coal, gas, solar, wind) having to compete for market share for the first time. It’s important to note that as an IPP his position and incentives are much different from those of regulated utilities like Xcel, who certainly do not want to “keep [their] rates to [their] consumers down and get these electrons onto its grid at a very cheap price”. And I think regulated utilities still make up a large majority of electrical generation in the US.
