U.S. wind energy industry finishes 2010 with half the installations of 2009, activity up in 2011, now cost-competitive with natural gas - Industry weathers latest boom-bust cycle as utilities move to lock in more wind power at favorable long-term rates
"Wind power is a great deal right now in many areas of the country," said Denise Bode, CEO of the American Wind Energy Association (AWEA). "However, our industry continues to endure a boom-bust cycle because of the lack of long-term, predictable federal policies, in contrast to the permanent entitlements that fossil fuels have enjoyed for 90 years or more.
"Now that we're competing with natural gas on cost, we need consistent federal policies to ensure we have a diverse portfolio of energy sources in this country, and don't become overreliant on one source or another."
AWEA reported today that 3,195 megawatts (MW) of wind-powered electric generating capacity came online in the fourth quarter of 2010. That performance was below the 4,113 MW installed in the same period in 2009, but a leap from the third quarter of 2010, when only 670 MW were installed. The U.S. finished the year with a total of 5,115 MW of new wind power.
Buoyed by a one-year extension of the 1603 Investment Tax Credit for renewable energy in the final days of the 111th Congress, the industry entered the new year with over 5,600 MW of electric power currently under construction, well above the same time a year earlier. Further projects are expected to start up in time to meet the new construction deadline for the tax credit, now set to expire at the end of 2011. The industry is likely to finish 2011 ahead of 2010 numbers, according to Elizabeth Salerno, AWEA Director of Industry Data & Analysis.
"Wind's costs have dropped over the past two years, with power purchase agreements being signed in the range of 5 to 6 cents per kilowatt-hour recently." Salerno said. "With uncertainty around natural gas and power prices as the economy recovers, wind's long-term price stability is even more valued. We expect that utilities will move to lock in more wind contracts, given the cost-competitive nature of wind in today's market."
Total U.S. wind capacity now stands at 40,180 MW, an increase in capacity of 15% over the start of 2010, AWEA reported today. For the first time, U.S. capacity fell second to China's; China now has 41,800 MW in operation, an increase of 62% in capacity over a year ago, according to a Jan. 13 report from the Chinese Renewable Energy Industries Association.
With uncertainty over national policies still holding back the U.S. industry, state targets for renewable energy continue to drive wind installations in many areas of the country. "We'll continue to work for a strong federal energy policy that drives the deployment of renewable energy technologies in the 112th Congress," Bode said, "but we'll also be defending and improving on state renewable targets, as well as promoting other sources of demand - such as more distributed and community wind projects, and corporate purchasing under the new WindMade trustmark."
The top five states for cumulative wind energy capacity at the close of 2010 all have such state targets:
Texas: 10,085 MW
Texas, the leading wind power state in America for several years running, achieved a major milestone by surging past the 10,000-megawatt mark for total installations, a quarter of all wind capacity in the U.S., with the addition of 680 MW in 2010. Known as the hub of the oil-and-gas industry, Texas achieved the mark thanks to aggressive pursuit of renewable energy and a renewable electricity standard passed in 1999 and strengthened in 2005. On average, wind now generates 7.8% of the electricity in the Electric Reliability Council of Texas (ERCOT) which covers most of the state, peaking as high as 25%.
Other states active in pursuing targets for renewable energy last year were Illinois (498 MW added), California (455 MW), South Dakota (396), and Minnesota (396 MW). Five more states, which generally began tapping their inexhaustible wind resources more recently than the leaders, showed growth rates above 100%. The list starts with Delaware and Maryland, which added their first utility-scale wind turbines in 2010:
Delaware & Maryland: First utility-scale installation
South Dakota: +126%
With the addition of Delaware and Maryland, 38 states now have utility-scale wind projects, and 14 of those have now installed more than 1,000 MW of wind power.

Six Distributional Effects of Environmental Policy

The effects of climate policy on multiple output prices are calculated in CGE (Computable General Equilibrium) models by Elliott et al (2010) and by Rausch et al (2010), but a simpler analytical general equilibrium model of Fullerton and Heutel (2010) aggregates carbon-intensive goods and finds that an increase in the CO2 price from $15/ton to $30/ton would raise that output price by 7.2%. They then use data on spending and incomes of thousands of households in the Consumer Expenditure Survey (CEX) to find that the ratio of burden to income rises monotonically across annual income deciles. The first eight deciles lose more than average, while the highest two income deciles lose less than average.

UC Davis study finds greenhouse gas emissions can hurt companies' stock value
The greater the carbon emissions, the lower a company's stock, all other factors being equal, the researchers found. The study was led by Paul Griffin, a professor in the UC Davis Graduate School of Management.
Griffin and his colleagues also discovered that markets respond almost immediately when a company reports an event that could affect global climate change, with stock values responding the same day as the disclosure.
The findings bolster the arguments of investor groups, environmental advocates and watchdog organizations that have been seeking greater disclosure of company actions that affect climate change.
Although the U.S. Securities and Exchange Commission does not require all companies to report greenhouse gas emissions, firms are bound by a rule that mandates disclosure of any information material to stock values. Today, about half of large U.S. firms report greenhouse gas emissions through the Carbon Disclosure Project, a British organization representing mostly institutional investors.
Griffin and colleagues David H. Lont of the University of Otago in New Zealand and Yuan Sun of the University of California, Berkeley, analyzed four years of data (2006-09) on firms listed in the Standard & Poor's 500 and five years of data (2005-09) for the top 200 publicly traded firms in Canada.
The researchers developed mathematical models to analyze the data. They found the link between stock values and greenhouse gas emissions to hold true in most industries, although the correlation was strongest for energy companies and utilities.
“After controlling for normal valuation factors like assets and earnings, we found the value of stocks to be a function of greenhouse gas emissions,” Griffin says.
Many firms file formal notices with the SEC and issue press releases following an event that could affect climate change. The researchers identified approximately 1,400 such reported events by firms in the study.
The researchers then tracked movements of stocks on days around when these events were reported. “We see a response on exactly the day you would expect to see it, and that is when the information becomes public,” Griffin says.
Why do investors care about greenhouse gas emissions? Griffin says markets are always looking forward, and in this case they appear to be anticipating a time when companies responsible for climate change will face increased costs for mitigation, regulation and taxes.
“They are examining the economic impact of what a company is doing on climate change, and they are assessing whether that is positive or negative for the company's value,” Griffin says.
