If you're an economist, like David H. Wang, you wake up some days muttering, "What has happened to the industrial base in the U.S. economy?"

The auto companies are practically on life support, and other sectors are paring-back operations, even as international competition mounts. Hundreds of thousands of jobs have been lost. How did this happen? Eight more years of industrial base decline without a viable plan to counteract it? And now, as a result of the financial crisis and de-leveraging, the prospect of a period of less-available credit threatens to delay economic recovery.

Well one remedy for the above, Wang argues, is to invest in the industrial sector via investing in the United States' infrastructure. And what's one project worthy of consideration? Investor T. Boone Pickens' plan to substantially increase domestic wind power via his Pickens Plan, Wang argued.

Pickens' investment fund has fallen on tough times, as of late. His BP Capital investment fund has shrunk by 60%, due to energy sector losses, and will drop to about $500 million after redemptions, by week's end, Pickens told CNBC Thursday. Pickens, who sees oil sector consolidation, expects the price of oil to recover to $100 per barrel in 2009. Oil Thursday closed down $1.81 to $65.69 per barrel.

Pickens Plan: a better investment than AIG?

Wang is less certain about a $100 oil price in 2009, but he is certain about the merit and benefits from investing in Pickens' project, and his argument is compelling. (Wang added that he does not have an investment stake in any power/energy company.)

Almost on cue, following oil's $12 rise in two days to $134, the International Energy Agency said the world needs to invest an additional $45 trillion in the decades ahead to vastly expand both nuclear power and wind power capacity to meet global energy needs.

Strictly speaking, the IEA's call to action was rooted in reducing the world's greenhouse gas emissions and achieving what it argues will be "a clean, clever, energy future" and not to move away from oil or fossil fuels solely on cost grounds. (pdf)

Still, the report's 2050 ETP Baseline scenario projects that CO2 emissions will rise by 130% and oil demand will rise by 70% - - the latter total being equal to five times Saudi Arabia's current oil production. If the IEA's oil projection is correct, that would suggest additional large increases in the price of oil in the decades ahead - - on top of oil's more than 400% price rise since 2001.

General Electric and Vestas Wind Systems are reaping the benefits as U.S. utilities assertively add generating capacity from renewable/alternative energy sources, Bloomberg News reported Wednesday.

For example, XCel Energy (NYSE: XEL), the U.S.'s largest provider of wind power, is buying 67 General Electric (NYSE: GE) turbines for a Minnesota wind farm, and GE expects its turbine sales to increase 25% to $6 billion this year, Bloomberg News reported. GE was the largest supplier of wind turbines in 2007, with a 45% market share. Siemens AG (NYSE: SI) and Vestas are two other major global manufacturers of wind turbines that should continue to benefit as wind power usage increases: each is opening manufacturing plants in the U.S. to accommodate increased wind energy-related sales.

GE's shares gained 89 cents to $34.29, while Siemens AG rose 20 cents to $128.20 in Wednesday afternoon trading.
