DETROIT, Aug. 20, 2013

DETROIT, Aug. 20, 2013 /PRNewswire/ -- DTE Gas, a subsidiary of DTE Energy
Company, is providing pipeline-quality natural gas, which was converted from
landfill gas, to its residential customers as part of its commitment to
renewable energy.

DTE Gas' BioGreenGas program contributes to the development of that
pipeline-quality natural gas at the Sauk Trail Hills landfill in Canton, Mich.
Residential natural gas customers can support the company's green efforts by
subscribing to the program for $2.50 per month.

DTE Gas is the first utility in Michigan and one of the first in the country
to develop such a program for residential customers.

"Our customers are as concerned about the environment as we are," said Mark
Stiers, DTE Gas vice president of gas sales and supply. "They have asked us
for a renewable energy option on the gas side of the business. BioGreenGas was
created in response to our customers' requests."

Since the program was launched last year, 2,000 customers have subscribed and
dozens more are on the waiting list. DTE Gas is looking into expanding the
program to meet the additional demand. The fact the gas comes from a local
landfill seems to appeal to customers.

"DTE has a commitment to supporting Michigan businesses," said Stiers. "We
could buy gas from anywhere, but we chose to locally source our green gas,
while helping to improve the environment in our home state. DTE's partnership
with Clean Energy Renewable Fuels made it possible for us to offer
BioGreenGas."

Clean Energy Renewable Fuels (CERF), a division of Clean Energy Fuels,
develops U.S. production facilities that generate and sell renewable natural
gas. CERF created a state-of-the-art plant to purify the biogas at Sauk Trail
Hills landfill.

DTE Pipeline Company invested approximately $2 million to build a pipeline and
a meter station at Sauk Trail Hills. DTE utilized local workers and created
approximately 50 construction jobs.

CERF invested approximately $20 million in the project and created about 80
construction jobs. Four additional workers were hired to permanently staff the
site.

"Our biomethane project at the Sauk Trail Hills landfill is an excellent
example of the practical solutions we can implement now to dramatically reduce
greenhouse gas emissions associated with our energy use," said Harrison Clay,
president of Clean Energy Renewable Fuels.

Combining CERF's technology with DTE Gas', renewable energy can be delivered
to natural gas customers in Michigan and across the country.
