Duke Energy Ohio is seeking proposals for renewable energy resources. The energy company says it’s looking to begin delivering energy through more renewable means sometime between 2009 and 2012. The effort falls in line with Ohio’s new renewable energy portfolio standards.

Types of renewable resources that would qualify:

— Wind energy
— Solar photovoltaic or solar thermal energy
— Geothermal energy
— Fuel derived from solid wastes not mainly due to combustion
— Biomass energy
— Hydroelectric power
— Biologically derived methane gas
— Energy derived from pulping/wood manufacturing
— Fuel cells
— Storage facilities that use off-peak power from renewables.

The recent Ohio energy law requires Ohio utilities to generate 50 percent of their renewable power from facilities located within the state.
