For some time, individuals in the NASA field centers have taken part in the program by providing reviews of proposals we receive for funded research. We expect that this cooperation will continue. We have invited the NASA Lewis Research Center to undertake tasks in wind energy research and other subprogram areas.

The Lewis Research Center is sponsoring a wind energy workshop, and is actively examining our suggestions to participate in other areas. I feel sure that arrangements will be worked out for further NASA participation in the solar energy program. For example, we have also initiated discussions leading to the possibility of further participation by the Jet Propulsion Laboratory in the solar energy program. Discussions on further participation in the energy program by the laboratories of the Atomic Energy Commission and the Department of Defense are also under way. I think it is important to note, Mr. Chairman, that technologies from the space program are making important contributions to the terrestrial applications of solar energy, including, for example, development in the area of solar thermal systems; the early developments of selective optical coatings and heat pipe developments actually came out of the military space program. We are moving aggressively to put them to work dealing with our domestic energy problems.

Finally, I should mention the international aspects of solar energy. The NSF has been designated as the lead agency for U.S.-U.S.S.R. cooperation in solar energy. Members of our staff have visited the Soviet Union and both solar and geothermal energy were included in a cooperative agreement signed in March 1973. We are also engaged in cooperative activities with other European countries.

In addition to the U.S.S.R., we are aware of significant solar energy activities in Japan, France, Israel, India, Canada, Australia, Italy, the Netherlands, and Greece, as well as smaller efforts in a number of other countries. Japan has over a million domestic solar water heaters in use. France has built three solar-heated homes and plans 31 others. Australia is operating solar-powered water distillation systems. In the minds of some, therefore, the indications are that solar energy may well emerge as an area of international technological competition.

In summary, the NSF research effort has contributed to the understanding of our total energy system, identified options and opportunities for advanced research and technological development, and established the basis for proceeding with a hard-driving solar energy effort. Solar energy gives excellent prospects for providing substantial help in dealing with the critical energy problems forecast for the 1980's and beyond. Our goals in solar utilization as we move into the next century (AD/RA 73-2329) are to provide some 35 percent of the energy needed for building heating and cooling and to supply the energy equivalent of 30 percent of the Nation's gas fuel, 10 percent of the Nation's liquid fuel and 20 percent of the Nation's electric energy. This completes my statement, Mr. Chairman. We will be pleased, with my colleagues, to answer any questions you may have.
