ExC-ELL Land-Based Wind PowerWind deployments on a steep upward climb “Today, deployed wind power in the United States has the equivalent generation capacity of about 60 large nuclear reactors (4). Wind is the first non-hydro renewable energy source to begin to approach the same scale as conventional energy forms like coal, gas, and nuclear.
“This success has been decades in the making—with both government and private-sector R&D dollars propelling its progress. From a technology standpoint three elements have been key to wind power’s success. The first is increasing size: wind
36
y p gturbines have gotten progressively larger in terms of generation capacity over the past 30 years and this has helped to drive down costs. In fact, since 1999 the average amount of electricity generated by a single turbine has increased by about 260%. The second is the scale of production. As with many industries, increases in scale tend to drive down costs. Finally, wind farm operators have become much more sophisticated in understanding and adapting to dynamic wind patterns. This has helped drive up the “capacity factor”—or the percentage of time that turbines are actually producing electricity. The federal Production Tax Credit—which pays an additional 2.3¢ a kilowatt hour for the electricity produced by wind turbines over the first 10 years of operation—has also been critically important to incentivizing deployment of wind energy.”

Gaining Force For decades, America has anticipated the transformational impact of clean energy technologies. But even as costs fell and technology matured, a clean energy revolution always seemed just out of reach. Critics often said a clean energy future would “always be five years away.”
This report focuses on four technology revolutions that are here today. In the last five years they have achieved dramatic reductions in cost1 and this has been accompanied by a surge in consumer, industrial and commercial deployment. Although these four technologies still represent a small percentage of their total market (e.g. electricity, cars and lighting), they are growing rapidly.
The four key technologies this report focuses on are:
Onshore wind power Polysilicon photovoltaic modules LED lighting Electric vehicles
In recent years, it has become increasingly clear that well-designed federal and state incentives and investments in research and development have the potential to stimulate significant energy transformations. For instance, from 1980-2002 the U.S. federal government’s production incentives for shale gas and support for new drilling technologies laid the foundation for that industry’s dramatic rise.2 Today, time-limited tax credits for wind, solar and electric vehicles and targeted support for research and development are supporting the expansion of these burgeoning markets.
This analysis explains both the magnitude of and mechanisms behind these nascent revolutions – exploring the intersection between declining costs and surging demand. These industries are providing real world solutions for reducing emissions of harmful carbon pollution and slowing the effects of climate change. Each of the sectors examined has also become a major opportunity for America’s clean energy economy.
The trends in each sector show that the historic shift to a cleaner, more domestic and more secure energy future is not some far away goal. We are living it, and it is gaining force.
1Levelized cost is often cited as a convenient summary measure of the overall competiveness of different generating technologies. It represents the per-kilowatt hour cost (in real dollars) of building and operating a generating plant over an assumed financial life and duty cycle. Key inputs to calculating levelized costs include overnight capital costs, fuel costs, fixed and variable operations and maintenance (O&M) costs, financing costs, and an assumed utilization rate for each plant type. As with any projection, there is uncertainty about all of these factors and their values can vary regionally and across time as technologies evolve and fuel prices change.

Land-Based Wind Power
Wind deployments on a steep upward climb3 Today, deployed wind power in the United States has the equivalent generation capacity of about 60 large nuclear reactors.4 Wind is the first non-hydro renewable energy source to begin to approach the same scale as conventional energy forms like coal, gas and nuclear.
This success has been decades in the making – with both government and private-sector R&D dollars propelling its progress. From a technology standpoint three elements have been key to wind power’s success. The first is increasing size: wind turbines have gotten progressively larger in terms of generation capacity over the past 30 years and this has helped to drive down costs. In fact, since 1999 the average amount of electricity generated by a single turbine has increased by about 260%. The second is the scale of production. As with many industries, increases in scale tend to drive down costs. Finally, wind farm
3Bolinger, Mark; Wiser, Ryan. MEMORANDUM - Documentation of a Historical LCOE Curve for Wind in Good to Excellent Wind Resource Sites; Lawrence Berkeley National Laboratory, June 11, 2012. Bloomberg New Energy Finance power plant database (1980-1994) and American Wind Energy Association wind industry database (1994-2012). 4 This number refers to “nameplate capacity” which represents the peak generation capacity of a wind turbine, solar panel, etc. In practice, electricity generation from renewable resources is variable – which means that they do not always produce at nameplate capacity.

operators have become much more sophisticated in understanding and adapting to dynamic wind patterns. This has helped drive up the “capacity factor” – or the percentage of time that turbines are actually producing electricity. The federal Production Tax Credit – which pays an additional 2.3¢ a kilowatt hour for the electricity produced by wind turbines over the first 10 years of operation – has also been critically important to incentivizing deployment of wind energy.
Skyrocketing demand, downward trending prices Since the beginning of 2008, wind power capacity has more than tripled in the U.S. This has happened despite a jump in wind turbine costs from 2001 to 2009. But that rise in turbine prices is, in some senses, misleading. The cost to install the same sized turbine, in an area with the same level of wind resource has gone down. However, as more of the prime real estate for building wind farms – windy terrain near power lines and big cities – is populated by wind turbines, developers have moved to areas that are farther away from population centers and power lines, or have lower wind quality. To compensate for lower wind speeds, many turbines are manufactured with bigger blades – to catch more wind. These bigger blades are more expensive, and this increase in costs was accentuated by the steep climb in commodity prices (e.g. steel and oil) from 2004-2008. But as commodity prices have receded, the average cost of new wind power has also started to recede, and deployment of wind turbines has skyrocketed. In 2012, the U.S. deployed almost twice as much wind as it did in 2011. In fact, wind accounted for 43% of new electrical generation capacity in the U.S. – more than any other source.
The future of wind Wind continues to be one of America’s best choices for low-cost, zero carbon, zero pollution renewable energy. The combined potential of land-based and off-shore wind is about 140 quads – or about 10 times U.S. electricity consumption today. And wind is 100% renewable, so it won’t ever run out. The industry is working to build new power transmission lines from some of the windiest parts of the country, to the most densely populated in order to maintain aggressive growth in the sector. This also includes building “marine” wind farms offshore – where steady ocean breezes harbor vast wind power potential. With continued technology improvements and policy support, the Department of Energy estimates that as much as 20% of projected U.S. electricity demand could be met by wind power by 2030.5

Electric Vehicles
Accelerating deployment Electric cars run on cheap, clean and increasingly green American energy. Over the past five years, the Administration and industry have worked together to bring down the cost of EVs through funding research and development on batteries and promoting consumer adoption of EVs through tax and other incentives. Today, the numbers are clear: more and more drivers are abandoning the gas pump for the affordability and convenience of in-home electric charging.
A race to the clouds Before 2010, U.S. EV demand was almost nothing. But in 2012, Americans bought more than 50,000 plug-in electric vehicles. In the first half of 2013, Americans doubled the number of EVs they purchased compared to the same period in 2012.
To maintain this momentum the most critical area for cost reductions is batteries. Energy Department models for EV battery fabrication costs show that the cost of high volume EV batteries has fallen by more than 50% in the past four years. While actual battery production costs are a closely held industry secret, price reductions in commercial EVs also appear to be on a steady downward glide. These cost reductions can be attributed to a number of factors. So-called “process improvements” – which increase the efficiency of manufacturing by eliminating wasted materials, capital and time – are one key element.

So is higher production volume – which helps amortize capital costs for expensive facilities, assembly lines and robots used to build batteries. Finally, automakers are integrating new materials into EV batteries that both reduce cost and increase energy-density – or the amount of energy that can be stored in a battery. Today batteries are receiving an enormous amount of attention from universities, research labs, industry and government because of their critical role in enabling EVs and other clean energy technologies. Because of this, we expect costs will continue to decline even further.
Road to the future In many senses, EVs are already competitive with traditional cars. For instance, for three years in a row the Chevy Volt has topped JD Power’s APEAL Study on consumer satisfaction for compact sedans. And this spring Consumer Reports said the Tesla Model S was the best car they had ever tested.15 Fueling these cars is also cheap compared to filling up a gasoline-powered car. The Energy Department calls this cheap electric fuel an “eGallon,” and today an eGallon –the amount of electricity it takes to drive an EV the same distance a standard car can travel on one gallon of unleaded gasoline – costs only about $1.22. This is in large part because electric motors are about three times as efficient as combustion engines.
But further progress on reducing the cost of EV batteries will make these benefits available to a larger audience. Some private sector analysts have said that there is a relatively clear technology path to $200/kwh for battery storage by 2020.16 The Department is working with industry, academia and our own labs toward an even more aggressive goal of $125/kwh by 2022. At that point, ownership costs for a 280-mile EV will be equal to a standard vehicle.17 All around the world, automakers are competing feverishly to design and deploy the electric car of the future. Today America is leading that race and every year, more and more Americans are fueling their cars on cheap, clean, secure, American energy.
15 The Tesla Model S is our top-scoring car, Consumer Reports, May, 2013 16 Hensley, Russell; Newmanm, John; Rogers, Matt. Battery Technology Charges Ahead; McKinsey Quarterly, July 2012. 17 For more information see the Department of Energy’s EV Everywhere Blueprint, http://www1.eere.energy.gov/vehiclesandfuels/electric_vehicles/10_year_goal.html

Conclusion As these and other clean energy industries continue to expand, so will the challenges and opportunities associated with transforming America’ energy sector. Already utilities are beginning to wonder how they will support their current business models in the face of increased energy efficiency and cheap rooftop solar power. As EVs move beyond the market for “first adopters” and become a mainstream, America will have to invest in building a smarter, more robust electrical grid and an extensive network of EV charging stations.
Those challenges are emblematic of successes in these clean energy markets. Indeed, electric vehicles, solar PV, wind power and LED lighting are all on track to transform our economy for the better. They will clean up the air in our cities, reduce America’s vulnerability to unstable international oil markets and help build an economy that is more competitive and more efficient.
The Energy Department’s goal is to encourage these trends by providing performance targets, support for R&D, consumer education and targeted deployment assistance. With continued progress in critical renewable and energy efficient technologies like these, we can look forward to a future of clean, green, American-made energy. Already for some of these innovative technologies, that future is here today.
