Detroit Zoo to meet 100% renewable energy by 2021

 The Detroit Zoological Society (DZS) in Michigan, United States, has recently announced that the Detroit Zoo will meet 100% use of the renewable energy generated in the state. This is part of the society’s “Greenprint” plan to continuously reduce the environmental impact and will be conducted through the “MIGreenPower” that is a CO2 emission reduction support program offered by DTE Energy, an integrated energy company. 7,425 metric tons of carbon dioxide which is equivalent to the amount absorbed by 8,740 acres of forests in one year will be reduced.

 The DZS is nationally recognized as a leader in environmental education with winning four green awards for advanced sustainability efforts. The Detroit Zoo has already introduced an anaerobic digestion system that converts herbivore animal waste and food scraps into compost and energy by action of microorganisms and made solar and electric hybrid golf carts and bicycles available in the zoo. Also, the Detroit Zoo installed a “Smartflower,” a solar panel system that generates more than 4,000 kilowatts of electricity annually, as the first zoo in the country.

 And the zoo has also eliminated the sale of single-use plastic water bottles and prohibited the use of plastic bags, straws, and lids. In cooperation with DTE Energy, the DZS improved the energy efficiency in more than 50 buildings and converted all lights to LED lighting in the zoo. To achieve 100% renewable energy, DTE will source renewable energy from three new wind plants that will come online in late 2020.
