Natural gas and nuclear power lead other power sources when it comes to generating clean and affordable energy, a recent report from two Michigan entities says.

The 130-page report authored by Northwood University and the Mackinac Center for Public Policy, both in Midland, gave a B- grade to coal after analyzing eight energy sectors based on capacity, reliability, environmental and human impact, innovation, and market feasibility.

“We ranked eight key energy industry sectors based on their ability to meet growing demand for affordable, reliable and clean electric generation,” co-author Dr. Timothy G. Nash, executive director of the McNair Center for the Advancement of Free Enterprise and Entrepreneurship at Northwood University, said in a statement.

The report gave the sector’s final grades:

• Natural Gas: A.

• Nuclear Power: B+.

• Coal: B-.

• Hydroelectric: B-.

• Petroleum: C-

• Geothermal: D+.

• Solar: F.

• Wind: F.
