Report: Energy-Efficient Lighting has Lower Environmental Impact
A new Energy Department report finds that LED
lamps have a significantly lower environmental impact than incandescent
lighting and a slight environmental edge over compact fluorescent lamps
(CFLs). The report, LED Manufacturing and Performance, compares
these three technologies from the beginning to the end of their life
cycles, including manufacturing, operation, and disposal. The most
comprehensive study of its kind for LED lamps, the report analyzes the
energy and environmental impacts of manufacturing, assembly, transport,
operation, and disposal of these three lighting types. It is the first
public report to consider the LED manufacturing process in depth. See
the LED Manufacturing and Performance report .
This is the second report produced through a
larger Energy Department project intended to assess the life-cycle
environmental and resource costs of LED lighting products in comparison
with traditional lighting technologies. It utilizes conclusions from the
previous report, Review of the Lifecycle Energy Consumption of Incandescent, Compact Fluorescent and LED Lamps, released in February 2012, to produce a thorough assessment of the manufacturing process. See the Review of the Lifecycle Energy Consumption of Incandescent, Compact Fluorescent and LED Lamps report .
The initial report concluded that CFLs and
today's LEDs are similar in energy consumption—both consuming
significantly less electricity over the same period of usage than
incandescent lighting—and that operating these products consumed the
majority of the energy used throughout their life cycles. Similarly, the
new report finds that the energy these lighting products consume during
operation makes up the majority of their environmental impact, compared
to the energy consumed in manufacturing and transportation. Because of
their high efficiency—consuming only 12.5 watts of electricity to
produce about the same amount of light as CFLs (15 watts) and
incandescents (60 watts)—LED lamps were found to be the most
environmentally friendly of the three lamp types over the lifetime of
the products, across 14 of the 15 impact measures examined in the study.

Energy Department Honors Utilities with Public Power Wind Awards
The Energy Department on June 19 recognized
three utilities—two in Minnesota and one in California—with the 2012
Public Power Wind Award. Minnesota's Moorhead Public Service and the
Minnesota Municipal Power Agency, along with California's City of Palo
Alto Utilities, received the awards. The American Public Power
Association (APPA) and the Energy Department's Wind Powering America
initiative created the Public Power Wind Award to recognize APPA-member
utilities that demonstrate outstanding leadership in advancing wind
power and furthering energy independence.
Now in its tenth year, the annual award
recognizes APPA members in three categories: Small Member System, Large
Member System, and Joint Action Agency. Moorhead Public Service received
the Small Member System award for its years of leadership in wind
energy that began with its pioneering utility-scale wind investments in
1999. The City of Palo Alto Utilities received the Large Member System
award for delivering 17% of its energy mix from wind power, and for
using wind energy to provide 97.5% of the renewable energy credits the
utility uses for its green power program, PaloAltoGreen. And Minnesota
Municipal Power Agency received the Joint Action Agency award for
installing a wind turbine in each of its member communities, with which
it collaborated to develop the 44-megawatt Oak Glen Wind Farm in Steele
County, providing enough electricity to power 14,000 homes. See the DOE Progress Alert and the Wind Powering America website.
EIA Sees Energy Efficiency Slowing U.S. Energy Consumption
Increased energy efficiency will contribute to a
slowing of the annual growth rate of U.S. energy consumption from 2012
to 2035, expanding at an average annual rate of 0.3%, according to a new
study from the U.S. Energy Information Administration (EIA). The agency
recently released its Annual Energy Outlook 2012, which
includes both a reference case and 29 alternative cases. By comparision
to the lower projections, the U.S. growth rate of energy consumption was
1.8% in 2005. In the reference case, the share of U.S. energy
generation from renewables is projected to grow from 10% to 15%. The
report describes how different assumptions regarding market, policy, and
technology drivers affect energy production, consumption, technology,
and market trends.
According to the report, the slowdown in the
rate of growth in energy usage reflects increasing energy efficiency in
end-use applications, among other things. In one basic scenario, EIA
estimates the overall U.S. energy consumption will expand at an average
annual rate of 0.3% through 2035. During this period, the United States
won't return to the levels of energy demand growth experienced in the 20
years prior to the 2008-2009 recession. The authors cite existing
federal and state energy requirements and incentives as playing a
continuing role in more efficient technologies. Additionally, new
federal and state policies could lead to further reductions in energy
consumption. The document also examines the potential impact of
technology change and the proposed vehicle fuel efficiency standards on
energy consumption. See the EIA press release, and the complete report.
New Power Line Delivers Renewable Energy to San Diego
The $1.9 billion Sunrise Powerlink, a
500,000-volt transmission line linking San Diego, California, to the
Imperial Valley, is now in service after a five-year permitting process
and 18 months of construction. San Diego Gas & Electric announced on
June 18 that the line will connect San Diego with one of the most
renewable-rich regions in California. For environmental reasons, nearly
75% of the tower locations required helicopters to set the tower
structures and it took more than 28,000 flight hours to complete the
aerial construction.
The Sunrise Powerlink will soon deliver a
significant amount of wind and solar power to San Diego. Over the past
three years, San Diego Gas & Electric signed eight renewable energy
agreements for more than 1,000 megawatts of solar and wind power from
projects in Imperial County. In 2011, more than 20% of the utility's
power came from renewable energy, and by 2020, it will get 33% from
renewable resources. See the San Diego Gas & Electric press release.
IEA: Renewable Energy to Grow During the Next 5 Years
Global renewable power generation is expected to
continue its rapid growth over the next five years, according to a new
report from the International Energy Agency (IEA). The Medium-Term Renewable Energy Market Report 2012,
released on July 5, says that despite economic uncertainties, global
power generation from hydropower, solar, wind, and other renewable
sources is projected to increase by more than 40% to almost 6,400
terawatt hours by 2017. That amount would be roughly one-and-a-half
times the current electricity production in the United States.
The study examines in detail 15 key markets for
renewable energy, which currently represent about 80% of renewable
generation, while it identifies developments that may emerge in other
important markets. Of the 710 gigawatts of new global renewable
electricity capacity expected, China accounts for almost 40%, with the
United States, India, Germany, and Brazil also contributing to the
growth. The report presents detailed forecasts for renewable energy
generation and capacity for eight technologies: hydropower, bioenergy
for power, onshore wind, offshore wind, solar photovoltaics (PV),
concentrating solar power, geothermal, and ocean power. Hydropower is
projected to have the largest increase in generation, followed by
onshore wind, bioenergy, and solar PV.
This expansion is underpinned by the maturing of
renewable energy technologies, in large part due to supportive policy
and market frameworks. However, rapidly increasing electricity demand
and energy security needs in recent years have been spurring deployment
in many emerging markets. These new deployment opportunities are
creating a virtuous cycle of improved global competition and cost
reductions. See the IEA press release.

One Cool Change at Energy HQ
The Forrestal Building, which stands as the
centerpiece of the Energy Department's headquarters complex, has
recently undergone a change that will save the U.S. taxpayers an
estimated $600,000 every year.
"Through the installation of the new chiller
plant, we're saving money on our air conditioning bills with more
efficient equipment while providing much more reliable air conditioning
to our critical facilities", said Peter O'Konski, director for the
department's Office of Administration. "That's good for our environment,
our customers, and our bottom line."
The chiller plant was constructed through an
Energy Savings Performance Contract, a public-private partnership that
allowed the department to apply industry best practices and use private
financing for the project. The financing costs are recovered from energy
savings.
The partnership is also ushering in improvements
like LED exterior lights, steam trap repairs and a variable air volume
system that are expected to save $59.5 million in the long term. For the
complete story, see the DOE Energy Blog.
Making Efficiency a More Efficient Business
By Roland Risser, program manager, Building Technologies Program
Even with the sweltering heat and relaxation
that summer usually brings, the Energy Department's Better Buildings
Neighborhood Program is showing no sign of slowing down. This week, the
program is hosting the Residential Energy Efficiency Solutions: From
Innovation to Market Transformation conference, bringing together
approximately 400 administrators and implementers of residential energy
efficiency programs and associated stakeholders. Six new case studies, a
business models guide and a video showcasing energy efficiency upgrade
professionals are debuting at the conference. Each was designed to
inspire communities across the country to save money, create new jobs,
and foster business opportunities.
The six case studies—profiling successful
workforce development and incentive initiatives in Maine, Michigan,
Oregon, and Pennsylvania—are a great resource for any energy efficiency
upgrade professional. Each addresses key topics such as participant
recruitment, workforce training, and cost barriers that contractors and
consumers face. For the complete story, see the DOE Energy Blog.
