It was a year ago that we wrote in this column about the stifling effect of operating in silos. Our particular focus was (and still is) on the unfortunate split between the renewable energy and energy efficiency options which crops up in all sorts of ways – as separate organizations, government project and policy programs, conferences and consumer marketing campaigns. We thought that now would be a good time to take a look at how IREC is doing in closing the divide between renewable energy and energy efficiency.
