Yes. China is already World leader in Wind Energy.

How does China intend to ensure intermittent wind can be added at this level and result in a stable grid? Ramping coal plants is one inefficient and environmentally unsound approach. What about large-scale energy storage? This would help with their planning smart transmission installations as well? What is the best course for a developer of such solutions to present to the state agencies in charge of these intiatives in China? Anyone have strong insight? Thank you.

The new report from the John Mjuir Trust exposes the industrial wind scam as follows:

The John Muir Trust report (PDF link), published on Wednesday, says output from wind farms metered by the National Grid is often less than 10% of their capacity.
It says wind "cannot be relied upon" to provide any significant level of energy generation at any defined time in the future and there is an "urgent need" to re-evaluate the implications of relying on wind power to meet Scotland's future energy needs.
Report author Stuart Young said, "Over the two-year period studied in this report, the metered wind farms in the UK consistently generated far less energy than wind proponents claim is typical.
"The intermittent nature of wind also gives rise to low wind coinciding with high energy demand. Sadly, wind power is not what it's cracked up to be and cannot contribute greatly to energy security in the UK."

The Chinese won't have any better luck.

cgreico:
There is no utility scale energy storage, unless you have an accessible pumped hydro facility. Denmark dumps most of its wind production to Norway and Sweden at a big loss. They use the power to refill their dam reservoirs.
As to a stable grid, wind above 10% is a nightmare.

Most of these wind farms are not connected. Building new wind farms but not connecting these to the system is Orwellian - or Quixotic - nonsense which ever adjective one prefers. But nonsense all the same! Hugh Sharman at www.DimWatt.eu

Rolf, I totally agree with you. Check out www.gravitypower.net --- flexibly sited in-ground pumped storage hydropower --- we aim to provide the access you to which you refer.

The variability of electricity from windpower is irrelevant.
There are other sources that can be controlled easily, such as hydro power.
This is used always to control the total amount of electicity at a given moment, to match real time demand at that time.
When windpower is added in the mix, the variability in demand is not significant different.
This is proven in denmmark and spain
Spain shows this in real time on the internet

Click on the pie sectors, Eolica is windpower.

Be aware that the chinese build their windparks for prices between 600 and 800 dollar per MW
This is cheaper than fossile power plants in Europe and the US.
And windpower does not need any fuel.

Word is that also the japanes have discovered that windpower is better than nuclear.

About the grid connectedness of chinese windparks
Windparks deliver poser to local and regional communities and industry
Chinese industy is moved to areas where the large windparks are producing.

To henk-daalder-156480: you hit the spot!!! And thank you very much for the spanish link, very interesting.

We have to save fuel and foster innovation. Wind is not pandora, it is defenitely part of it. If it wouldn't be efficient to be built and used the chinese would defenitely not use it.

To cgrieco: Very interesting as well. A question: Is it possible to buid a watertight tunnel 2 km in the ground with a tollerance of a few mm so that waterseals (I counted 4) remain functional? Geological deformation could disrupt the system quite easily in my view.

Rolf Westgard : " Denmark dumps most of its wind production to Norway and Sweden at a big loss. They use the power to refill their dam reservoirs. As to a stable grid, wind above 10% is a nightmare. "

you are wrong. Denmark uses 68% of it's generated windpower electricity in Denmark, the rest is exported to neighboring countries when local demand is too low (nights, weekends). Norway and Sweden do not have any pumped up hydro facilities, they are all regular hydropower plants that shutdown when Denmark exports it's wind power, since wind power is cheaper than hydropower.
Wind power has the lowest marginal production costs in the Nordic power system. For example, the Danish electricity prices for industries (excl. tax and VAT) are the 7 lowest out of 27 European countries. The price of electricity production and distribution for household consumers including 20 percent wind power is the 10 highest out of the 27 EU countries.

read following PDF to understand how little you understand about Denmark's power grid.

Wind above 10% is NOT a nightmare, if I can believe a study executed by Siemens in the Island of Ireland, copy pasted hereunder for your understanding.

http://www.renewableenergyfocus.com/view/10343/ireland-can-accommodate-40-renewable-electricity/

The power system in Northern Ireland and the Republic of Ireland can accommodate the ambitious 40% target for renewable energy by 2020, according to Ecofys.
This conclusion comes from an extended technical analysis of the future power system, performed by Ecofys, Siemens PTI, Ecar Ltd and DIgSILENT in collaboration with Eirgrid and SONI engineers as well as using independent Irish wind energy experts Professor Mark O'Malley, UCD, and Peter Harte at SWS Energy.
The studies suggest that above the 60-80% instantaneous penetration level of wind power has to be temporarily curtailed.

Hold the accolades on China's 'green leap forward'

http://www.washingtonpost.com/opinions/hold-the-accolades-on-chinas-green-leap-forward/2011/04/19/AFLdZMEE_story.html

Just as China produces everything from trinkets to supertankers, it is exporting green technology — which makes it a giant of manufacturing, not of environmental friendliness.
In wind power, China both produces and consumes. In 2009, it put up about a third of the world's new wind turbines. But much of this has been for show. A 2008 Citigroup analysis found that about one-third of China's wind power assets were not in use. Many turbines are not connected to the transmission grid. Chinese power companies built wind turbines that they didn't use as the cheapest way of satisfying — on paper — government requirements to boost renewable energy capacity.
Consider the bigger picture: 87 percent of the energy produced in China comes from fossil fuels, the vast majority of it from coal, the International Energy Agency found in 2010.
The explosive recent growth in Chinese solar and wind generation equates to going from zilch to a small fraction: Wind today generates just 0.05 percent of China's energy, and solar is responsible for one-half of one-thousandth of 1 percent.
The reason China does not use more wind and solar power is simple: Even when mass-produced with cheap labor, solar panels and wind turbines are not cost-effective replacements for fossil fuels. They appear so in the West only where politicians create generous subsidies for their implementation.

AN IDEA
Most Wave Energy websites do not provide detailed technical information. They seem to act as a marketing tool. There is no wisdom in withholding information.
Developers are protected by Patents and by Intellectual Property rights. Moreover; due to the size of investment and to business acumen, no one would risk infringement on a Patent and/or Intellectual Property rights.
Lot of efforts and funds are wasted on systems that are in conflict with engineering principles, or no feasibility study is made to check for system constructability, viability and economy.
Our decision for Publishing System Calculations and Drawings would allow developers to scrutinize the system, improve system performance, provide collective knowledge and improve the proposed WGD system or come up with a totally new system.
Calculations and Drawings would be sent to all our contacts. We invite all visitors of this website, in case of interest, to request a set of Calculations and Drawings.
Once an offshore wind farm is planned for construction then it is worth to investigate utilization of the offshore to extract maximum energy. This is achieved by adding to the offshore wind farm reversible Ebb/Tide turbines and a wave energy extraction system.
Wave energy is considered as one of the most promising alternate energy source due to high concentration factor and to high availability factor (day & night), compared to wind and solar energy.
Waves have energy ranging from 3.8 to 432 KW for 0.75 to 8 meters height respectively per 1.5 meters of wave front. Total average power generated range between 0.24 and 111.1 KW per wave pass of 360 degrees.
