Around this time last year, I blogged about some misconceptions on U.S. and China’s installed wind capacity and wind energy generation, highlighting that the U.S. was producing 64% more wind energy than China in 2011 with the same amount of turbines. I explained the reasons for this including China’s difficulties with their Renewable Energy Law, grid connection bottlenecks, and performance gaps due to technology and wind resource issues. In this blog, I’d like to provide a quick update on the U.S. and China wind energy development using newly released 2012 data, and then offer up a prediction for the rest of the decade.
According to GWEC, the U.S. and China installed nearly the same amount of wind capacity in 2012 with 13.1 gigawatts (GW) and 13.2 GW, respectively. This was a record year for the U.S. (previous record was 10 GW in 2009).
Of that 13.1 GW installed in the U.S., 5.5 GW was installed in December alone, as project developers rushed to bring their assets online ahead of the expiration of the Production Tax Credit (PTC, which later ended up being extended).
China now has more grid connected wind capacity than the U.S. with 62 GW compared to the U.S.’s 60 GW, but the U.S. produced 40% more wind energy than China in 2012.
83% of wind turbines (or 5 of 6) in China are grid connected now, compared with a low of 63% in 2009, providing evidence that China’s grid connection bottleneck is easing.
Wind accounted for 3.5% of total electricity generation in the U.S. in 2012, compared to 2.0% in China.
Looking into my green crystal ball, here’s my bold prediction about the US-China “wind energy race,” if there ever was such a thing.

Even as the world powers try to hammer out a contract at the climate summit, the tempers in Copenhagen are running high. In a rather harsh use of language Chinese vice foreign minister has called US climate negotiator extremely irresponsible.
At the United Nations climate change summit to be held in Copenhagen in December, much of the spotlight will be on Asian giants India and China. They are demanding that rich countries take the lead in reversing global warming, but are reluctant to accept a cap on their own carbon emissions. From New Delhi, Anjana Pasricha examines the position that the world’s most populous countries have adopted on this issue.
I recently had an opportunity to speak with Gerry Gurevich, the technical lead for EPA’s Health and Environmental Research Online—or HERO—database, which serves as a central location for the scientific information EPA researchers use to develop environmental and health assessments. Gerry explained some of the benefits of the HERO database and the changes that will occur over the coming months.
For starters, HERO has greatly enhanced transparency by providing links to the references and abstracts of the scientific literature used in two important types of Agency assessments: (1) Integrated Risk Information System (IRIS) assessments, which evaluate information on the potential health effects that may result from exposure to environmental contaminants, and (2) Integrated Science Assessments (ISAs), reports that summarize the science related to the health and ecological effects caused by the six criteria air pollutants for which EPA develops National Ambient Air Quality Standards.
With approximately 725,000 references, there is an abundance of information. If you need a scientific reference from an ISA or IRIS assessment, HERO will have it! … (read more).

Welcome to Transition Studies. To prosper for very much longer on the changing Earth humankind will need to move beyond its current fossil-fueled civilization toward one that is sustained on recycled materials and renewable energy. This is not a trivial shift. It will require a major transition in all aspects of our lives.
This weblog explores the transition to a sustainable future on our finite planet. It provides links to current news, key documents from government sources and non-governmental organizations, as well as video documentaries about climate change, environmental ethics and environmental justice concerns.
The links are listed here to be used in whatever manner they may be helpful in public information campaigns, course preparation, teaching, letter-writing, lectures, class presentations, policy discussions, article writing, civic or Congressional hearings and citizen action campaigns, etc. For further information on this blog see: About this weblog. and How to use this weblog.
