Members of Cobb EMC, Cobb Alliance for Smart Energy and Georgians for Smart Energy will mark Valentine’s Day by delivering 1,000 Valentine thank-you letters to Cobb EMC on Tuesday.

The letters were written by EMC members and clean energy advocates thanking the Marietta co-op’s board for severing ties last month with a coalition of EMCs developing the Plant Washington coal plant in Sandersville, Ga. Cobb EMC have spent $13.5 million toward the plant’s development.

Cobb EMC and CASE members will gather at 10 a.m. on Tuesday at Runaround Sue's, 1397 Church Street Ext. in Marietta across from the Cobb EMC headquarters before delivering the cards.
