a fast, cost-effective, and environmentally sound way to prevent future energy shortages in the United States while reducing the Nation’s dependence on imported energy supplies, is to encourage and facilitate, through major programs, the implementation of energy conservation and renewable-resource energy measures with respect to dwelling units;

weatherization of such dwellings would lower shelter costs in dwellings owned or occupied by low-income persons as well as save energy and reduce future energy capacity requirements; and

States, through Community Action Agencies established under the Economic Opportunity Act of 1964 [42 U.S.C. 2701 et seq.] and units of general purpose local government, should be encouraged, with Federal financial and technical assistance, to develop and support coordinated weatherization programs designed to alleviate the adverse effects of energy costs on such low-income persons, to supplement other Federal programs serving such low-income persons, and to increase energy efficiency.
