appear insignificant in veiw of the larger and general problem of energy needs. However, when considered together in terms of the total energy supplied, this variety of uses becomes a major asset in the consideration of solar energy applications. A recent study undertaken under the auspices of the United Nations Conference on New and Renewable Sources made the following conclusions relating to water heating: In developing countries . . . water heating requirements by solar energy could significantly reduce the overall use of non-renewable energy. In developing countries, although the energy currently used for heating is on the order of 5-8% of total domestic energy consumed, availability of reliable solar water heaters at affordable cost could significantly help in providing heated water to the population — particularly low income groups and especially to those living in colder parts of the developing world (4). The same study also contained the following statement with regard to the possible benefits of solar cooking: TABLE 3 PROJECTED PRODUCTION OF PRIMARY ENERGY IN DEVELOPING COUNTRIES, 1985 AND 2000 (MILLIONS OF TONS OF OIL EQUIVALENT)
