China to be 3rd biggest wind power producer: media

China's installed wind power capacity will reach 20 gigawatts this year

China is set to become the world's third largest wind power producer in 2009, state media reported, as the Asian giant seeks various ways to expand energy supply to power its economic boom.

The country's installed wind power capacity will reach 20 gigawatts this year, said Shi Lishan, vice director of the National Energy Administration's New Energy Department, the Xinhua news agency said Wednesday.

That will lift China to surpass Spain and become the world's third biggest wind power producer after the United States and Germany, the report said.

The United States had 25.2 gigawatts in installed capacity of wind power in 2008, or 20.8 percent of the world's total, compared with China's capacity of 12.2 gigawatts, figures from the Global Wind Energy Council showed.

At the end of last year, Spain had 16.8 gigawatts of installed wind power, the council said.

China, which relies on coal for more than 70 percent of its energy, is the world's largest emitter of the greenhouse gases blamed for global warming.

But it has set a target of generating 15 percent of its energy from renewable sources -- mainly wind and water -- by 2020.

The country was criticised for obstructing the adoption of a treaty on during an international summit in Copenhagen earlier this month.

However, in a move signalling its commitment to cutting emissions, the nation last week adopted a law supporting the industry by obliging firms to buy all the power produced from renewable sources.

Yeah your probably right, renewable energy projects are a really bad idea when they aren't enormous. It would be a lot better to release all of that CO2. Why even try if you can't fix it all at once?

China total installed wind by year...

2005 1,266
2006 2,599
2007 5,912
2008 12,210
2009 22,500

Pretty close to a doubling each year.

China set a goal in 2007 of 20 gigs of installed wind by 2020. They've hit their 2020 goal ten years early.

China now predicts 100 gigs of installed wind by 2020. And an additional prediction of 15% of its energy from renewables by the end of this decade.

I think fingersinterlaced was making a different point than the one you saw. If not, let me make it. These renewable projects are certainly worth while, but right now, we need to focus on the low hanging fruit. The lowest of the low hanging fruit is efficiency. We could cut emissions in half just by decreasing usage by increasing efficiency with existing technology that is more cost effective than spending it on the energy in the first place! This would have exactly 0 effect on standard of living. It is a win/win. Japan and France, not to mention Denmark got that long ago. It is time we wake up and reprioritise. Does that mean reducing green energy projects? Absolutely not! It means equaling that spending by focusing exactly equally on efficiency. That's the point!

Fingersinterlaced said: in 2007 China had an installed capacity total of 624 gigawatts of electricity generation and consumed a total 2.718 TERAWATT.

So they use 4x as much as they make?

Fingersinterlaced said: We still need increased efficiency, and we continually get it. Turbo diesel and electric cars, LCD computer screens.

Hate to burst your bubble but LCD TV's and monitors are less efficient than the old CRT versions. They look snazzy etc. but they consume more power per unit size than CRT's.

All these factoids and solutions are useless unless we can get the world's population to stop growing.
If the world's population were a stable 2 billion I suspect that we could switch off every coal burning power plant.

The world's population growth is slowing down. It would be great if it slowed faster and the eventual peak were lower. Now that Bush is out of office perhaps the US can return to working on population.

In those parts of the world, those ethnic/religious groups who feel that "two aren't enough", perhaps we could start a program of "wait a while". If we could stretch the time between generations that would help.

"History has proven again and again that every increase in efficiency has lead to an increase in consumption."

That's Jeavons Paradox or Jeavons Effect. And it does not always apply.

Jeavons assumes conditions in which supply remains constant and price subsequently drops in response to lower demand. That lower price then boosts consumption.

As we move into new forms of energy production, be they renewables or nuclear, we are likely to see some price increase. Price will drive down consumption. People aren't going to going to switch to efficient light bulbs in order to cut their monthly utility bill and then go out and buy an electric butter warmer.

If you follow technology you will see that efficiency is the new goal, not 'faster and bigger'.

Big screen LCDs will be replaced with big screen OLEDs. California has already established the regulation that marks the end of energy hog big LCDs.

"Renewables look good on paper. Say for example you have a 1GW coal or nuclear powered plan, running at 90% capacity factor, that's 0.9GW (or 900MW).

To get the same 0.9GW from wind you need 2.25GW installed capacity. Try scaling that up to full roll out."

Nameplate vs. capacity does not matter. What matters is the cost per kWh of the power produced.

Some renewables such as wind, geothermal and biomass look good when you pay the bill. They are among the least expensive ways to produce electricity.

Solar is rapidly joining the least expensive group. At $2 per watt ($1 panel (almost reached) plus $1 BOS (balance of system)) solar reaches grid parity in sunny parts of the country.

We will have to configure a grid supply that uses geothermal, hydro, and biomass as the 'always on' sources and supplement them with a cocktail of intermittent sources, storage, load shifting, and (for a while) dispatchable natural gas.

The only problem with wind energy is the bat population, if the bats are harmed more than what is the risk of more disease from the insects they eat??? It may seem small but malaria is not something I would want. There are better ways of getting power through water and salt. Popular science magazine July 2006--The future of energy.

the government can't even agree on healthcare. the train is screaming toward a brick wall but look who's at the helm.

To really save energy, how about using more LED bulbs, rather than CFLs which trigger and/or exacerbate numerous medical maladies?

For info on CFL issues, visit

It seems it would be helpful to save dispatchable load without deleterious unintended (medical) consequences. That requires more efficient equipment, such as LED bulbs.

"People aren't going to going to switch to efficient light bulbs in order to cut their monthly utility bill and then go out and buy an electric butter warmer."

This is wrong. People can and do increase efficiency on their lighting then buy a new gadget. Just because it isn't a butter warmer doesn't mean it doesn't use power. Granted not everyone does this. Power use per capita is and has been steadily increasing even with the radidly growing fraction of people using cfl's.

Great idea. Sounds like a great and reliable mix.
