STEM Project Grants - Duke Energy Foundation recently announced a $75,000 matching gift to DonorsChoose.org to assist teachers in the fields of science, technology, engineering and math (STEM). According to program guidelines, public school teachers can submit STEM project proposals to www.DonorsChoose.org/teachers. When 50 percent of a project's request is funded through citizen donations, Duke Energy will contribute the remaining 50 percent for teachers in the company's North Carolina service areas. Qualifying projects already posted to the site will automatically be eligible for Duke Energy's matching funds.
