At NETL, maintaining responsible stewardship of the environment is crucial to the Lab’s mission of finding innovative solutions to America’s energy problems. Earth Day, celebrated since 1970, aligns closely with NETL’s vision while emphasizing the importance of recycling, conserving energy and improving air quality. Every year, NETL hosts an annual poster contest encouraging elementary school students at schools near NETL’s sites in Albany, Oregon; Morgantown, West Virginia; and Pittsburgh, Pennsylvania, to showcase their favorite ways to protect the environment. This year, students were asked to design their posters around the theme, “Protect our Earth’s Plants, Care for its Creatures,” in recognition of this planet-centric day. We have shared the first-, second- and third-place winning entries, as well as honorable mentions, at each grade level here. The top entries are also displayed at U.S. Department of Energy headquarters in Washington, D.C., and all NETL sites through May 10, 2019.
