Community College Energy Training Act of 2017 This bill directs the Department of Energy (DOE), in coordination with the Departments of Labor and Agriculture (USDA), to create a joint program under which the Departments award grants to community colleges to provide workforce training and education in sustainable energy industries and practices, such as: (1) clean energy; (2) high-performance green building construction, design, and redevelopment; (3) sustainable energy technologies; (4) water, energy, and resource conservation; (5) recycling and waste reduction; and (6) sustainable agriculture and farming. DOE, Labor, and USDA must: ensure that at least one-half of the grant funds are awarded to community colleges with existing sustainability programs leading to certificates, credentials, or degrees in such industries or practices; and give priority to community colleges that plan to use the grant to carry out programs developed and maintained through consultation with such industries and practices.
