Now, before you get all hot and bothered here, we should warn you that this study only uses information from within the great state of North Carolina (where Duke University is based, obviously), but the results are intriguing regardless. According to new data, the moment we're living in is a crossover one where the declining prices of solar panels may actually make sun-based energy more cost efficient to consider than nuclear. Duke found that the crossover price point was at around 16 cents per kilowatt hour (kWh), and for the first time ever in NC, the cost of one kWh of electricity from solar energy sunk below that. Of course, these results are apt to be even more impressive in sun-rich states like Arizona, Nevada and Utah, but it's fairly clear what the real purpose of the investigation was: convincing the school to shell out for solar panels to energize Krzyzewskiville during week-long campouts for UNC vs. Duke tickets.
