(NBC NEWS)-- BMW's South Carolina assembly plant is reaping the benefits of going green.
"It saves money and it also makes us more efficient," says Josef Kerscher, president of BMW Manufacturing.
Kerscher has overseen the "greening" of the South Carolina plant over the last five years.
Forklifts have been retrofitted to run off hydrogen fuel cells and energy is produced on-site from landfill gas.
"We've reduced the energy consumption per unit manufactured here more than 40% over the last five years," he points out.
The EPA was so impressed it recently added BMW to its Green Power Partners list for generating on-site, renewable energy.
With nearly 40 percent of its energy produced on site, BMW leads the country in relying on renewables.
Kerscher expects other companies to follow suit.
