Invesco PowerShares announced today that T. Boone Pickens, a leading authority on alternative energy, will participate in a webcast regarding America's dependence on foreign oil. The event, titled "Energy Solutions for the 21st Century," will be held on Tuesday, Jan. 27, 2009 at 4:00 p.m. EST and will be presented by Invesco PowerShares.

"We are honored to welcome T. Boone Pickens to discuss America's dependence on foreign oil and to share his perspective on alternative energy solutions. We believe the United States' dependency on foreign oil links three of the most critical issues we face today: the economy, the environment and national security," said Bruce Bond, president and CEO of Invesco PowerShares.

Pickens, founder and chairman of BP Capital Management, is the creator of the Pickens Plan, a grass-roots campaign aimed at reducing America's dependence on imported oil by harnessing domestic energy alternatives. The plan calls for building new wind generation facilities that would produce 20% of our nation's electricity and allow us to use natural gas as a transportation fuel.

Pickens will be joined by Bond in discussing his plan and how it pertains to President-Elect Barack Obama's alternative energy outlook. In addition, Invesco PowerShares National Sales Manager, Robert Brooks, will be present to discuss how PowerShares exchange-traded funds (ETFs) may relate to the Pickens Plan. The conference will conclude with a question and answer session featuring all three panelists.

The live webcast will be open to the public, and those interested in participating are encouraged to visit www.invescopowershares.com/webcast for registration details.
