riNDINGS AND POLICY 
note. 
SEC. 2. (a) The Congress hereby finds that— 
(1) the current imbalance between supply and demand for 
fuels and energy is likely to persist for some time; 
(2) the early demonstration of the feasibility of using solar 
energy for the heating and cooling of buildings could help to 
relieve the demand upon present fuel and energy supplies; 
(3) the technologies for solar heating are close to the point of 
commercial application in the United States; 
(4) the technologies for combined solar heating and cooling 
still require research, development, testing and demonstration, 
but no insoluble technical problem is now foreseen in achieving 
commercial use of such technologies; 
(5) the early development and export of viable solar heating 
equipment and combined solar heating and cooling equipment, 
consistent with the established preeminence of the United States 
in the field of high technology products, can make a valuable 
contribution to our balance of trade; 
(6) the widespread use of solar energy in place of conventional 
methods for the heating and cooling of buildings would have a 
significantly beneficial effect upon the environment; 
(7) the mass production and use of solar heating and cooling 
equipment will help to eliminate the dependence of the United 
States upon foreign energy sources and promote the national 
defense; 
(8) the widespread introduction of low-cost solar energy will 
be beneficial to consumers in a period of rapidly rising fuel cost; 
(9) innovation and creativity in the development of solar heat-
ing and combined solar heating and cooling components and sys-
tems can be fostered through encouraging direct contact between 
the manufacturers of such systems and the architects, engineers, 
developers, contractors, and other persons interested in installing 
such systems in buildings; 
(10) evaluation of the performance and reliability of solar 
heating and combined solar heating and cooling technologies can 
be expedited by testing under carefully controlled conditions; and 
(11) commercial application of solar heating and combined 
solar heating and cooling technologies can be expedited by early 
commercial demonstration under practical conditions. 
(b) It is therefore declared to be the policy of the United States and 
the purpose of this Act to provide for the demonstration within a 
three-year period of the practical use of solar heating technology, and 
to provide for the development and demonstration within a five-year 
period of the practical use of combined heating and cooling technology.

ment (as the case may be). 
(2) In addition, in the case of a federally assisted mortgage loan, 
the cost excess specified in subsection (a) shall be fully taken into 
account in determining the value or cost of the structure involved for 
purposes of applying any statutory provision specifying the maximum 
loan-to-value or -cost ratio; except that, if the law specifies different 
rates of downpayment for successive increments of such value or cost, 
the lowest such rate shall apply to the additional cost attributable to 
the solar heating or combined solar heating and cooling equipment, 
and such equipment shall otherwise be excluded in determining the 
total value or cost of the structure.

tems involved, and of the dwellings and other buildings themselves,

Act of 1974.

FINDINGS 
SEC. 2. The Congress hereby finds that— 
30 use 11 oi, 
(1) the Nation is currently suffering a critical shortage of 
environmentally acceptable forms of energy; 
(2) the inadequate organizational structures and levels of fund-
ing for energy research have limited the Nation's current and 
future options for meeting energy needs; 
(3) electric energy is a clean and convenient form of energy 
at the location of its use and is the only practicable form of energy 
in some modern applications, but the demand for electric energy 
in every region of the United States is taxing all of the alternative 
energy sources presently available and is projected to increase; 
some of the sources available for electric power generation are 
already in short supply, and the development and use of other 
sources presently involve undesirable environmental impacts; 
(4) the Nation's critical energy problems can be solved only 
if a national commitment is made to dedicate the necessary finan-
cial resources, and enlist the cooperation of the private and public 
sectors, in developing geothermal resources and other noncon-
ventional sources of energy; 
(5) the conventional geothermal resources which are presently 
being used have limited total potential; but geothermal resources 
which are different from those presently being used, and which 
have extremely large energy content, are known to exist; 
(6) some geothermal resources contain energy in forms other 
than heat; examples are methane and extremely high pressures 
available upon release as kinetic energy; 
(7) some geothermal resources contain valuable byproducts 
such as potable water and mineral compounds which should be 
processed and recovered as national resources;
