Benefits of Going Solar
Why have over
1.5 million Americans invested in solar? Surveys
taken over the last ten years confirm that the vast
majority of owners (94% or more) consider that investment
a wise decision. Consumer investment and satisfaction
have spawned a small but growing solar hot water (SHW)
industry here in the U. S. that is providing even broader
benefits to our nation and has the potential to contribute
much more. |
Clean and Safe Solar
hot water systems in use today produce approximately
1000 megawatts of energy annually. That is the equivalent
of two medium-sized coal plants. The life-cycle costs
of SHW systems are about the same as gas and far better
than electric water heating systems.
Solar energy is pollution-free, an important benefit when
the cost of removing pollutants from the environment is
considered. For example, a typical SWH system will, over
its lifetime, displace 10.5tons of CO2 if replacing
a natural gas system, or 71.5 tons if replacing an electric
system. |

Resource The U. S. Department of Energy estimates
that Americans consume approximately 2.5 quads of end-use
energy annually to produce hot water at a cost of over
$20 billion dollars. Solar energy currently provides
only a tiny fraction of that demand, but huge portions
of our country possess sufficient insolation to produce
much greater quantities of energy.
Enough sunlight reaches the earth’s surface each yearto
produce approximately 1000 times the same amount of
energy produced by burning all fossil fuels mined and
extracted during the same period. Sunlight does not
have to be explored, mined, extracted, transported,
combusted, transmitted — or imported.
Quality, Reliability, Durability
Solar water heating technology, pioneered in the U.
S., is the oldest and most developed of all renewable
energy systems. Modern solar water heating systems can
provide a large portion (40 - 80%) of household hot
water demand depending on local climate conditions and
the size and type of system. Most systems pay for themselves
in four to sevenyears and continue to provide hot water
for many years thereafter. |

Much of the United States receives abundant
sunshine, making solar hot water systems
a very economical investment. This map shows the average
daily solar radiation available on a south-facing surface
measured in megajoules per square meter each day.

Solar pool heating often provides an
even better investment. Payback can be as low as two
years and the solar system can extend the swimming season
by several weeks without additional cost. Many homeowners
have regretted the purchase of a conventional pool heating
system after receiving their first utility bill.
Another cost-efficient application for
solar energy is preheating ventilation air for commercial
and industrial facilities.
The vast majority of U. S. manufacturers of solar equipment
voluntarily comply with national consensus standards
developed by the Solar Rating and Certification Corporation
(SRCC). The SRCC tests and certifies collectors as well
as complete systems for performance, reliability and
durability. In addition, manufacturers and installers
comply with the SRCC’s strict requirements for proper
installation, labeling and homeowner information regarding
operation and maintenance. Assurances of performance
and quality are backed by warranties that in many cases
exceed the guarantees of other household appliances.
Made in America In 1960,
jobs within the energy industry (including coal mining,
oil and gas extraction, petroleum refining, electric
and gas utilities) represented about 1.8 percent of
total U. S. employment. By 1990 that share fell to 1.2
percent. “This ratio likely will decline further over
the next decade,” the U. S. Center for Global Climate
Change reported in 1993.
Employment patterns resulting from conventional energy
technologies are dominated by the capital-intensive
nature of the industry. When measured in jobs per million
dollars of annual expenditure, coal, oil, gas and nuclear
technologies support among the fewest jobs of any economic
activity.” The solar water heating industry is a good
example of the type of manufacturing needed to create
both new skilled and unskilled jobs.
Realizing the Potential
Several utilities all across the country—from the Sun
Belt to the Midwest and Northeast— offer consumers a
variety of programs to reduce the initial cost of solar
systems. In turn, the utility avoids the cost of installing
additional generating capacity, especially power to
meet peak energy demand, and using solar energy helps
the utility comply with every-increasing restrictions
on pollution emissions. |

In 1992, the U. S. Department of Energy along with
the Edison Electric Institute, American Public Power
Association, and their utility and industry members
established “Utility Solar Water” or USH2O.
USH2O will serve as a forum for interested
parties to develop and expand utility programs for residential
and commercial solar water heating.
Many state and federal government officials have acknowledged
the importance of solar hot water systems in many of
their programs.

These systems are examples of
installations resulting from a demand—side management
program at Sacramento Municipal Utility District. |

The federal government builds, owns and
operates more buildings than any other sector of the
economy. Managers of these buildings are learning
from the Federal Energy Management Program (FEMP) how
solar and energy efficiency can be combined to reduce
the energy load of their facilities and save millions
of taxpayers’ dollars.
The federal government also subsidizes the monthly
utility bills for millions of low- income families.
The State of Florida and the U. S. Department of Energy
have established a pilot program to demonstrate that
SHW on low-income housing can also save millions of
dollars in federal subsidies.
The Housing and Urban Development agency has undertaken
a project to establish criteria and mechanisms that
would allow mortgage lenders to give homeowners an advantage
for solar and energy efficiency measures when purchasing
a new or used home.
Solar water heating systems are already eligible for
the energy efficient mortgage programs which allow homeowners
to have higher debt-to-income ratios, thus allowing
them to qualify more easily for financing. In fact,
when SHW is incorporated into a mortgage, the monthly
finance charges attributed to the new system fall below
the monthly energy costs and give homeowners money in
their pocket every month.
In 1993, the National Association of Home Builder’s
Research Center included SHW, as well as other solar
options, in the Resource Conservation House, a single-family
residence built to demonstrate to builders the characteristics
and advantages of the many new products on the market
that are conserving our nation’s energy resources.
The United States is striving to reindustrialize with
new technologies that create jobs yet are environmentally
benign. The U. S. solar water heating industry is comprised
of the manufacturers profiled in this brochure plus
many distributors, installers and maintenance companies
nationwide. The question many people ask is “How can
the U. S. save money, help our environment, and create
jobs?
The answer has been up there all the
time - solar energy.
