TVA's Green Power Switch enters its 10th season with nearly 12,000 residential and more than 500 commercial participants in the voluntary program.
Renewable energy purchases, sold in $4 blocks of 150 kilowatt-hours a month, have offset 448,333 metric tons of carbon dioxide emissions, according to TVA. The savings are equal to the amount produced from burning about 1 million barrels of oil or 50 million gallons of gasoline.
"This program has been successful right from the start," TVA Executive Vice President of Customer Relations Ken Breeden said.
