We write a lot of stories these days about the remarkable growth of solar and wind power and how they are truly transforming the energy landscape. Another important component of this sea change is energy efficiency (EE), though we haven’t been writing as much about that, perhaps because it’s not as sexy and exciting as shiny new solar panels or towering wind turbines. But there is another reason: Investment in energy efficiency projects has been in a long-term decline, going back to a peak of about $2 billion annually in 1992, which has drifted down to about $1.2 billion in recent years.
Last year, utilities in Indiana were ordered to refund $32 million to ratepayers. Those funds represented the balance of $74 million that was collected for energy efficiency projects, many of which were never implemented.
