According to a
survey conducted by
the Biodiversity
Project, 67 percent
of Americans say
that they care about
the environment
because nature is
God’s creation

Did You Know?
If America’s more than 300,000 houses of worship
cut energy use by 10 percent…
Nearly $200 million would be saved for
congregations’ missions and other priorities.
More than 5.4 billion kWh of electricity would
be available without additional cost and pollution.
More than 2 million tons of greenhouse gas emissions would be prevented,
equivalent to the emissions of about 400,000 cars, or to planting over a
half million acres of trees.

"We do not inherit our world from
our ancestors; We borrow it from our children"
In the United States, the Environmental Protection Agency has estimated that
if 300,000 congregations cut back on their energy use by 25 per cent, invest
in more efficient heating and lighting systems, and adopt other
environment-friendly practices, they would save more than $500 million
annually. The efforts would also prevent more than five million tons of
greenhouse gas emissions from polluting the air, or “the equivalent of
taking one million cars off the road,” estimates the agency.
The congregation building is an emblem of our
faith and serves as the physical hub of our communal life. However, when we
spend too much money on building and maintenance we divert funds from other
projects which serve our mission. The financial advantages of an
environmentally responsible building are great, especially for congregation
buildings which are generally in place for the long term and will be used
for many years. A stable organization such as a congregation is an ideal
candidate for green building. The life-use of the facility is likely to be
under one owner, thereby creating opportunity to realize maximum benefit of
design and installations.
Most religious traditions teach stewardship
of financial and natural resources. Energy efficiency is an excellent means
of achieving both of these objectives at the same time, because energy saved
is both money saved and pollution prevented.
Energy costs represent a significant portion
of congregation budgets. While individual congregation expenditures vary
based on hours of operation, size and utility rates, a 1999 U.S. Department
of Energy commercial buildings energy consumption survey found that
congregations spend an average of $4,600 on energy costs each year. Large,
mega-church-sized facilities can spend close to that each month during their
harsher seasons. Worship facility managers have an opportunity to save money
and be environmentally responsible by improving the energy efficiency of
their HVAC system and minimizing building energy use, all while responding
to the diverse needs of their congregations.
Congregation Energy Related Building Data
The below table from the Energy Information
Administration shows some of the important energy data for the places of
worship in the United States. The numbers alone make a good case for
promoting sustainable building practices to such facilities.
