The recent passage of
H.R. 2454 (also known as the Waxman-Markey bill or American Clean Energy and
Security Act of 2009), raises concerns about the costs of climate change
mitigation. Energy efficiency investments are one of the more promising prospects
for mitigating such changes because they are cost effective and relatively straightforward
to implement. The American Council for an
Energy-Efficient Economy (ACEEE) recently released a study that highlights
the potential for energy efficiency investments to dramatically reduce greenhouse
gas emissions (GHG) while having a net positive impact on the economy. “The Positive Economics
of Climate Change Policies: What the Historical Evidence Can Tell Us”, by
John A. “Skip” Laitner, suggests that most evaluations of climate change policies
underestimate the cost-effectiveness of energy efficiency.
This conclusion is supported by findings from related reports. McKinsey &
Company’s 2009 report, ”Unlocking
Energy Efficiency in the U.S. Economy”, found that energy efficiency technologies
have a $170 billion annual market potential. A 2008
report by Lazard, an international financial advisory and asset management
firm, found that the levelized (average lifetime) cost of energy efficiency
improvements ranges from zero to five cents per kWh.
Given these findings, the ACEEE analysis of energy efficiency economics concludes
that these investments have a return on investment range of 10 to 25%. This
means that in as little as four years energy efficiency investments can pay
for themselves. From that point on, energy savings can help households and
businesses improve their bottom lines. By 2050, ACEEE estimates that energy
efficiency investments could cut energy bills in half for U.S. consumers and
businesses and reduce carbon emissions by as much as 7,167 megatons. As a
point of reference, the U.S. released 7,150 megatons of greenhouse gas emissions
in 2007.[1]
Another important benefit of energy efficiency investments is potential job
growth. These investments will replace energy intensive economic activities
with labor intensive economic activities. This finding is supported by the
work of Professor David Roland-Holst at the University of California. After
studying the macroeconomic implications of California’s innovative energy
policies, he found that efficiency programs have created about 1.5 million
full-time jobs with a payroll of $45 billion while saving about $56 billion
since 1972.[2]
These findings support the business case for energy efficiency investments
and may eventually help electrical distributors sell energy management projects,
by encouraging more money to flow to these investments. Please refer to NAED’s
