Krispy Kreme is giving away free green glazed doughnuts for those who visit shops wearing green Tuesday and Wednesday. No purchase is necessary, and the treats are available in-store, for pick-up and the drive-thru while supplies last. Budweiser says it is turning all beer “green” by pledging “renewable energy credits equivalent to the estimated electricity needed to brew every beer in the U.S. in a single day.” McDonald's kicked off the season of green early when it brought back minty Shamrock Shake and Oreo Shamrock McFlurry to restaurants nationwide Feb. 15. More people are expected to spend the holiday at home than past years, according to a survey of more than 3,000 consumers by Numerator. Only 9% plan to go to a bar this year compared to 38% in previous years.
