this article rather neatly shows why there wont be any manufacturing bases here, or anywhere else much, apart from Chinas, when it comes to PV and now wind turbine manufacture.
installing the ready made items isnt exactly going to employ many.

Now, Changsha and two adjacent cities are emerging as a center of clean energy manufacturing. They are churning out solar panels for the American and European markets, developing new equipment to manufacture the panels and branching into turbines that generate electricity from wind. By contrast, clean energy companies in the United States and Europe are struggling. Some have started cutting jobs and moving operations to China in ventures with local partners.

The booming Chinese clean energy sector, now more than a million jobs strong, is quickly coming to dominate the production of technologies essential to slowing global warming and other forms of air pollution. Such technologies are needed to assure adequate energy as the world’s population grows by nearly a third, to nine billion people by the middle of the century, while oil and coal reserves dwindle.

But much of China’s clean energy success lies in aggressive government policies that help this crucial export industry in ways most other governments do not. These measures risk breaking international rules to which China and almost all other nations subscribe, according to some trade experts interviewed by The New York Times.

A visit to one of Changsha’s newest success stories offers an example of the government’s methods. Hunan Sunzone Optoelectronics, a two-year-old company, makes solar panels and ships close to 95 percent of them to Europe. Now it is opening sales offices in New York, Chicago and Los Angeles in preparation for a push into the American market next February.

To help Sunzone, the municipal government transferred to the company 22 acres of valuable urban land close to downtown at a bargain-basement price. That reduced the company’s costs and greatly increased its worth and attractiveness to investors.

Meanwhile, a state bank is preparing to lend to the company at a low interest rate, and the provincial government is sweetening the deal by reimbursing the company for most of the interest payments, to help Sunzone double its production capacity.

Heavily subsidized land and loans for an exporter like Sunzone are the rule, not the exception, for clean energy businesses in Changsha and across China, Chinese executives said in interviews over the last three months.

But this kind of help violates World Trade Organization rules banning virtually all subsidies to exporters, and could be successfully challenged at the agency’s tribunals in Geneva, said Charlene Barshefsky, who was the United States trade representative during the second Clinton administration and negotiated the terms of China’s entry to the organization in 2001.

If the country with the subsidies fails to remove them, other countries can retaliate by imposing steep tariffs on imports from that country. But multinational companies and trade associations in the clean energy business, as in many other industries, have been wary of filing trade cases, fearing Chinese officials’ reputation for retaliating against joint ventures in their country and potentially denying market access to any company that takes sides against China.

on the left of the [age is the volume of wind turbines made by china..and they also happen to have most of the worlds rare metals involved IN the making of them, and have banned exports of said minerals..game set and match?
