Power utilities don't like to reveal data about their energy sources or sales any more than Internet organizations like to reveal security problems. The key to REPS is the reporting it requires:
"Beginning in 2009, each power supplier is required to file a compliance report, detailing the actions it has taken to fulfill the requirements of the REPS."This is called the Renewable Energy Certificate (REC) Tracking System. It provides the data to see which utilities are providing how much of which kind of energy.
According to Ivan Urlaub of the North Carolina Sustainable Energy Association (NCSEA), REC reporting enabled the solar industry in North Carolina:
"The passage of the REPS law in 2007 and resulting success of the North Carolina's clean energy market has created the rapid start-ups and expansions of clean energy businesses from installers to developers to manufacturers and the associated service sectors over the last few years."Not only is North Carolina now one of the national leaders in solar energy, but 91% of NC voters want more solar power, with wind second, and everything else far behind.
REC enabled not only a renewable energy industry, but also selection within that industry for what works.
How did this happen?
In addition to renewable energy system architecting, transport, installation, and maintenance, 56% of solar jobs in North Carolina are in R&D. REC data let NCSEA and others study the entire solar ecosystem.
