The DTE Energy company, which provides
and electric services to Michigan customers, is going to start using
in its fleet of 800
trucks and service vehicles (things like bucket
and light-duty vehicles). DTE will present a ceremony on Tuesday to mark the shift to the
, but didn't announce the percentage of biodiesel it will be using. DTE did say that Michigan-based biodiesel supplier RKA Petroleum will provide the fuel and that the switch is the "environmental equivalent of taking about 120 of those vehicles out of service." Since "environmental equivalent" can mean a lot of things, we can't just calculate the biofuel percentage. What we do know is that even if you're providing energy to a lot of people, greening up your own supply isn't a bad idea.
