The U.S. Department of Energy (DOE) is pursuing an all-of-

the-above approach to developing every source of American

energy. The Ofce of Energy Efciency and Renewable Energy

(EERE) leads DOE efforts to build a strong clean energy

economy, a strategy that is aimed at reducing our reliance on

foreign oil, saving families and businesses money, creating

middle-class jobs, and reducing pollution.

This strategy will position the United States as the global

leader in clean energy, increasing our nation’s competitiveness.

In 2012, $268 billion was invested globally in clean energy, a

500% increase since 2004.

Trillions of dollars will be invested

in the coming decades. Clean energy represents one of the most

important economic development races of the 21st century. We

face a stark choice—the clean energy technologies of tomorrow

can be invented and manufactured in Alaska and the rest of the

United States for domestic use and export around the world,

or we can cede global leadership and import those technologies

from China, India, Germany, and elsewhere.

Alaska State Summary: EERE Investments in Alaska

EERE and Alaska

EERE helps create Alaska’s clean energy economy today,

developing and delivering innovative, market-driven solutions

for the following:

• Sustainable transportation – making transportation cleaner

and more efcient through solutions that put electric drive

vehicles on the road and replace oil with clean domestic

fuels

• Renewable electricity generation – reducing the cost of

renewable energy through solutions that squeeze more

usable power from sustainable resources and improve

the economics of manufacturing and installation

• Energy-saving homes, buildings, and manufacturing –

developing cost-effective energy-saving solutions that

help make our country run better through increased

efciency—promoting better plants, manufacturing

processes, and products; more efcient new homes and

improved older homes; and other solutions to enhance

the buildings in which we work, shop, and lead our

everyday lives.

EERE Investments in Alaska

EERE invests in Alaska through a range of clean energy

projects, from energy efciency to hydropower, fuel cells, wind,

biofuels and biopower, and other technologies. EERE supports

cities, communities, and families to develop innovative, cost-

effective energy solutions through the research, demonstration,

and deployment activities we conduct with Alaska and its

businesses, universities, nonprots, and local governments.

Sustainable

Transportation

Low-Cost Production of Hydrogen and Electricity

Anchorage, Alaska

EERE investment: $2.4M

Atan airport in Anchorage, Alaska, EERE provided funds

to Bloom Energy in completing a one-year demonstration

oftwo 25-kilowatt fuel cells—providing valuable, real-world

data in one of the harshest environments on earth. Eachfuel

cell showedan impressive peak electrical efciency of more

than50%.The high operating temperature of these specic fuel

cells allows for a higher electrical efciency than lower tempera-

ture fuel cells, which a have a peak electrical efciency closer to

40% when operating on natural gas. In addition, a small-scale

electrochemical hydrogen pump was connected to an identical

25-kilowatt fuel cell system in Bloom’s laboratory to demon-

strate the coproduction of hydrogen and electricity.The gas

that is emitted by the fuel cell where the electricity is

generated is sent to the hydrogen pump, where the hydrogen

is then separated from the other gases, resulting in a pure

hydrogen stream.Data collected during the fuel cell demon-

stration and hydrogen pump validation testing, along with

subsequent analysis based on high-volume manufacturing,

shows the potential to produce low-cost hydrogen from natural

gas by simultaneously producing hydrogen and electricity.

Tapping the Power of Alaska’s Rivers

Delta Junction, Alaska

EERE investment: $142K

Partnering with Alaska’s Whitestone Power, EERE is sup-

porting efforts to develop a practical River In-Stream Energy

Conversion (RISEC)—a device that can produce electricity

from free-owing rivers not suited to conventional hydro-

electric generation, and that can do so in Alaska’s weather

conditions. Rural areas of Alaska frequently experience

high electricity prices due to the high costs of delivering

fuel to those areas. Under those conditions, technologies

like RISEC, when implemented at a commercial scale, may

provide a source of cost-effective electricity. Whitestone’s

project includes site analyses and surveys for RISEC facilities

in Alaska, theoretical modeling of structural RISEC compo-

nents, turbine blade and mounting prototype testing, and

application strategies. The company’s research yielded several

innovations that will drive future device designs, including

developing site-specic engineering solutions for effectively

applying RISEC technology in Alaskan river environments;

integrating stock components that reduce design, construc-

tion, and component replacement costs; and constructing a

modular design and exible control system that have broad

potential applications for meeting the power needs of remote

Alaskan villages. Whitestone and other project participants

contributed $37,000 to this project.

Alaska State Summary: EERE Investments in Alaska

Driving Wind Energy Adoption in Rural Alaska

Communities

Anchorage, Alaska

EERE investment: $2.5M

Supported by an EERE investment, the Alaska Energy

Authority (AEA) has commenced a variety of projects designed

to validate wind energy installations in the state’s harsh

climate. Wind energy installations can generate electricity and

reduce the need for fuel deliveries, the costs of which can be

extreme for remote rural communities, many of which are off

the electric grid. Because of Alaska’s weather, Alaska wind

projects require more study for adaptation of equipment and

proper siting than installations in other U.S. locations. AEA

completed an Environmental Assessment for the Toksook Bay,

Chevak, and Sand Point wind sites; AEA also constructed

both a 400-kilowatt wind project in Chevak and a 1-megawatt

wind project in Sand Point. AEA also organized and partici-

pated in outreach and education for wind and combination

wind-diesel systems; completed site-specic, wind-resource

modeling and feasibility studies for rural Alaskan communi-

ties; and constructed a foundation in Toksook Bay that is

designed to handle the adverse soil conditions in the Yukon-

Kuskokwim Delta. Future efforts will include developing

education and outreach capabilities at the University of

Alaska’s Wind-Diesel Applications Center; expanding support

for AEA’s Anemometer Loan Program, which provides rural

Alaskan communities the ability to collect and analyze wind

resource data; and conducting a foundation monitoring and

performance study at Toksook Bay. AEA and other project

participants contributed $2.8 million to this project.

Watching Whales: Measuring the Impact of Tidal Power

Installations on Endangered Belugas

Cook Inlet, Alaska

EERE investment: $600K

With EERE support, Ocean Renewable Power Company

(ORPC) is conducting a two-year study on the effects of

tidal turbines on endangered beluga whales in Cook Inlet,

Alaska—home to some of the greatest tidal energy potential

in the United States. To successfully permit and operate the

tidal power project in Cook Inlet, ORPC must conduct a

rigorous biological assessment of the potential and realized

effects that the tidal turbines’ physical presence and sound

footprint could have on the distribution, relative abundance,

and behavior of the whales. Prior to conducting the assess-

ments, ORPC will collect baseline data at the proposed

deployment areas near Fire Island and at the initial pilot

project site near East Foreland. Researchers will compare

measurement technologies and visual observation techniques

and, based on the assessment results, will recommend a best

practice for future data collection. When complete, this study

will help the tidal industry understand the potential impacts

of tidal energy projects on the belugas, which will inform

future siting and operation decisions.

EERE-funded researchers are evaluating the potential impacts of

tidal energy development on endangered beluga whales.

Alaska State Energy Efciency Appliance Rebate Program

Helps Disabled Alaska Residents

Statewide

EERE investment: $686K

Using EERE funding, the State of Alaska implemented

a state rebate program that is targeted especially for the

disabled. This program has helped bring energy-efcient

appliances within the affordability envelope for Alaska many

residents. In total, Alaska issued $643,011 in rebates, ranging

from $300 to $1,000 on ENERGY STAR

qualied clothes

washers, dishwashers, refrigerators, and freezers. The state

set higher rebate amounts for Alaskans who live in remote,

rural areas to help offset shipping costs—which could be

hundreds of dollars. Retailers helped advertise the program

and organized bulk sales to reduce shipping costs. Contact

in very remote areas of the state was often limited to group

excursions to stores in hub communities that served these

remote villages in surrounding areas. The rebate program

saved an estimated 400 million British thermal units and $28

million in energy and water cost savings annually.

Alaska Gateway School District Adopts Combined

Heat and Power

Tok, Alaska

In Tok, Alaska, the economic impact of high fuel prices

was crippling the community’s economy—especially for the

Alaska Gateway School District, with staff laid off and double

duties assigned to many. To help offset high energy costs,

Alaska State Summary: EERE Investments in Alaska

the school district decided to replace its separated diesel heat

and power systems with a biomass combined heat and power

(CHP) system. Northwest Clean Energy Application Center,

an EERE-supported organization, aided this project by

providing technical support to develop a woody biomass CHP

system, which uses a 5.5-million British thermal unit steam

turbine (120-kilowatt capacity) in lieu of diesel heating and

diesel power generation. The system heats the 80,000-square-

foot local school and will soon allow the school to construct

a greenhouse that will grow fresh vegetables for the school

district’s food service program. Tok School spends more than

$300,000 annually on heating fuel and electricity, and the

boiler will save an estimated $125,000 per year on fuel. Once

the CHP systems are fully operational, the rate of biopower

consumption will increase, with an anticipated use of 5–6 tons

of biomass per day; this biopower will displace approximately

65,000 gallons of heating fuel. Because of the biomass CHP

project’s anticipated and realized savings, Tok School has been

able to rehire three staff members for the school—a music

teacher, counselor, and boiler operator. Once more savings are

realized and biomass CHP is expanded into other sites, the

school anticipates further improvements to student services.

The Tok School is realizing signiﬁcant energy savings thanks to

its biomass-fueled combined heat and power system.

Deploying Clean Energy Solutions

in Alaskan Communities

EERE invests in the deployment of energy efciency and

renewable energy projects in communities across Alaska.

These investments catalyze economic development, create

jobs, generate clean energy, and reduce utility bills. Many

of these investments have been through American Recovery

and Reinvestment Act (ARRA) funds. Of the more than

$73 million in ARRA funds allocated to the State of Alaska

from EERE specically for deployment projects, more than

90% has been spent as of January 2013 through the Energy

Efciency and Conservation Block Grant Program, State

Energy Program, and Weatherization Assistance Program.

Building Clean Energy Infrastructure

With nancial and technical support from EERE, energy

ofcials at the state level and in 138 communities have selected

and overseen the completion of hundreds of projects that are

delivering the benets of clean energy to citizens throughout

Alaska. EERE allocated more than $55 million in ARRA

funds to support activities that

• Contributed to increased energy efciency and cost savings

for more than 1,300 buildings (nearly 6 million square feet)

through building retrots

• Installed 5 renewable energy systems, including wind,

solar, and geothermal energy systems

• Funded approximately 1,000 workshops, teaching more

than 10,000 people to perform energy audits and install

renewable energy systems.

Weatherizing Homes for Lower Income Families

Alaska has spent more than 82% of the more than $18

million in ARRA funds it received to weatherize 2,600 homes,

surpassing its goal. Statewide, this has resulted in annual

energy savings of more than 75 billion British thermal units

and has averted nearly 7,000 metric tons of greenhouse gas

emissions to date—the equivalent of taking more than 1,400

passenger vehicles off the road for a year. These projects have

enabled income-eligible families to save hundreds of dollars

per year on heating and cooling bills by improving their

homes’ energy efciency, as well as the health and safety of

home environments.

Deployment Project Examples

Upgraded “AKWarm” and “ARIA” Systems Will Improve

Energy Efciency Efforts in Alaska

Statewide

EERE investment: $1.7M

The State of Alaska used this investment to improve the capa-

bilities and usability of its building energy modeling program,

AKWarm, and its “back-end” building retrot information

database, Alaska Retrot Information System (ARIS).

AKWarm was expanded from a residential-only program to

include commercial buildings. Alaska then conducted invest-

ment-grade energy audits on as many schools and municipal

buildings as possible. The State uploaded data collected from

this effort into ARIS, and now has in-depth knowledge of the

energy performance for many public buildings across Alaska.

Knowledge obtained from the experience of this project will

help improve the design, construction, and operations of

Alaskan public buildings. The energy audits performed through

this project provide information for many municipalities and

school systems to now be able to apply for low interest loans

from the Alaska Energy Efciency Loan Program to install the

efciency measures that the audits recommended.

Alaska State Summary: EERE Investments in Alaska

Deploying Energy Efciency Measures in Remote

Alaska Villages

Statewide

EERE investment: $3.7M

The Alaska Energy Authority (AEA) installed energy

efciency measures that are enabling 51 remote villages across

the state to save money both immediately and for years to

come. AEA installed measures that include upgraded lighting

and mechanical systems at selected buildings. For these

upgrades, AEA furnished and installed all necessary wiring,

thermostats, motors, pumps, and electrical control system

modications. AEA also provided weatherization services to

residential homes. AEA completed these improvements in the

face of daunting challenges with regard to climate, access,

logistics, materials, and energy costs. Many villages have a

very limited construction season, as road access is seasonal—

even non-existent at times. Materials must be barged in

from Portland or Seattle, and only when the ice has melted

from Alaska’s rivers and bays, because shipping in materials

by air is prohibitively expensive. Much of the work on this

project was contracted to local residents, who were trained to

operate and maintain the installed systems. These investments

will support local jobs and reduce costs to communities, as

they will not need to hire outside technicians. These energy

efciency measures are expected to save Alaska communities

574 kilowatt hours of electricity and 84,000 gallons of

heating fuel annually; the measures are also expected to pay

for themselves in about 3 years.

Tlingit and Haida Tribes Provide Training and

Technical Assistance

Tlingit and Haida Indian Tribes

EERE investment: $666K

The Tlingit and Haida Indian Tribes of Alaska, serving

southeastern Alaska, was selected to receive funds for its

Weatherization Training Center, as the center has proven to

be a great resource for researching resolutions to marine cold

climate issues. The Tlingit and Haida Indian Tribes are also

working with the University of Alaska Southeast to train

tribal weatherization crews.

Remote Community of Tanana Residents Increasing

Energy Independence

Tanana, Alaska

EERE investment: $1.5M

The City of Tanana—a small community of less than 300 on

the Yukon River in central Alaska—is improving the energy

efciency of public buildings and installing biomass heating

units. Energy efciency is particularly important in Tanana,

as some residents have been forced to leave due to Tanana’s

historically very high energy costs. The city believes that clean

energy, specically energy efciency and harnessing local

biomass sources, is the key to its future. Instead of shipping

in fuel on costly seasonal barges or propeller planes, residents

are now harvesting their own energy sources in the form

of driftwood oating down the Yukon River. Self-reliance

is critical in Tanana’s isolated location, and these activities

allow residents increase their energy independence. Tanana

is also working with other rural communities throughout

Alaska to share best practices and lessons learned.

A Proven Track Record

Snapshot of National Outcomes from EERE Investments

• EERE’s $931 million investment in vehicles combustion engine R&D from 1986 to 2007 achieved a net beneﬁt of $69 billion

(2008 dollars) in fuel savings for users of heavy-duty diesel trucks.

• EERE’s $3.7 billion investment in solar photovoltaic R&D from 1975 to 2008 resulted in a net economic beneﬁt of $15 billion

(2008 dollars) due to module eciency and reliability improvements.

• EERE’s $1.7 billion investment in wind energy R&D from 1976 to 2008 resulted in a net economic beneﬁt of $8.7 billion

(2008 dollars) due to wind turbine eciency, energy capture, and reliability improvements.

• A 2001 National Academy of Sciences analysis found that investments of $1.6 billion in energy eciency R&D in the ﬁrst two

decades of DOE’s existence from 1978 to 2000 realized a net economic beneﬁt of approximately $30 billion (1999 dollars).

• EERE research has helped reduce production costs of automotive lithium-ion batteries by more than 50% since 2008 and is on

track to reach its goal of enabling cost-competitive market entry of plug-in hybrid electric vehicles within the next 10 years.

• EERE’s activities to achieve cost-competitiveness for biofuels have resulted in the recent achievement of reaching a modeled

cellulosic ethanol production cost of $2.15 per gallon of ethanol (or $3.27 per gallon of gasoline equivalent).

• EERE’s eorts have reduced the projected costs of automotive fuel cells (assuming high-volume manufacturing) by more than

35% since 2008 and 80% since 2002—doubling the durability of fuel cells from 950 hours of demonstrated operation in 2006

to more than 2,500 hours of operation on the road.

• Without EERE involvement, the average solar photovoltaic (PV) module production cost per watt would have been $5.27 in

2008, rather than $1.92. EERE has accelerated solar industry progress by an estimated 12 years.

• Without EERE involvement, cumulative wind power deployment through 2008 would have been less than a third of actual

2008 levels. EERE has accelerated the overall progress of the wind industry by an estimated 6 years.

• More than 6,200,000 homes have been weatherized with EERE funding provided to states or leveraged from other sources with

EERE support since 1976—creating an average energy savings of $350 or more per year and avoiding $1.6 billion in energy costs

during winter 2005 alone for all households weatherized.

• Due to EERE appliance standards implemented through 2012, a typical household today already saves about $180 per year o its utility

bills. Households can expect to save more than $300 per year by 2030, as they replace their existing appliances with newer models that

use less energy—a cumulative savings to consumers of more than $900 billion by 2020, and more than $1.6 trillion through 2030. The

cumulative energy savings of these standards phased in through 2012 will be about 70 quadrillion British thermal units (quads) of energy

through 2020, and will amount to 120 quads through 2030. (The United States consumes a total of about 100 quads of energy per year.)

• EERE and its partners in the manufacturing sector have successfully launched 220 new, energy-ecient technologies, received 78

R&D 100 Awards, and delivered technical assistance to more than 33,000 industrial plants.

• Since 2005, EERE has facilitated $3.1 billion of eciency investments in federal government facilities from performance-based

contracts, which will result in energy cost savings of approximately $8.5 billion over the life of the energy-saving measures. The

savings on utility bills and operation and maintenance created through the facility upgrades will be used to pay for the project over

the term of the contract, and the agencies will continue to save money and energy after the contract term has ended.

The Oce of Energy Eciency and Renewable Energy is at the center of creating the clean energy economy today. We lead U.S. Department of Energy
