Chip Hoffman said he thinks alternative energy is the wave of the future.
"I know it will be," said the 47-year-old from Warren. "We can't rely on oil and fossil fuels anymore."
Hoffman, an electrician with 30 years of experience, is one of dozens of students who have gone through Macomb Community College's renewable energy program.
The program is designed to train people for jobs connected with green energy technologies.
