| Naperville continues with its coal-heavy provider because it’s widely believed that solar and wind are more expensive than coal. | Solar and wind have been cheaper than coal for over a decade, according to levelized cost of electricity (LCOE) data. Because of this, solar has been the fastest-growing source of new electricity in the U.S. for five years straight. |
Despite solar and wind becoming significantly cheaper over the past decade—as shown by the steady decline in their levelized costs compared to coal—Naperville remains locked into a coal-heavy contract signed in 2007 that doesn’t expire until 2035, preventing a switch to cleaner, more affordable energy for years to come.
