Invesco PowerShares, one of the world's leading providers of clean energy ETFs, now offers investors a relatively low-cost, focused, global approach to investing in wind energy.

What is wind energy?

Wind energy (or "wind power") is an inexhaustible, global form of renewable clean energy. Wind power requires no mining, drilling, water usage or transportation of fuel, and does not generate air, water, radioactive or any other hazardous or polluting waste.¹ Wind is harnessed, converted into energy and distributed for residential and commercial use through wind turbines located around the world. In 2007 alone, global wind power installations equaled the capacity of 20 large-size conventional power plants.²

Energy demand is growing worldwide. It is expected to rise by 53% between 2006 and 2030 with 30% of this demand coming from developing nations like China and India.³ As a result of this rising energy demand, attractive clean energy alternatives have become multi-billion dollar markets.²

In 2007 wind power crossed a milestone, becoming the first $30 billion clean energy industry. This number is expected to grow to over $80 billion over the next 10 years.¹

The PowerShares Global Wind Energy Portfolio is an exchange-traded fund (ETF) based on the NASDAQ OMX Clean Edge® Global Wind Energy Index (Index). The Index is designed to measure the performance of global companies engaged in the wind energy industry, which are primarily manufacturers, developers, distributors, installers and users of energy derived from wind sources.

There are risks involved with investing in ETFs, including possible loss of money. The Funds are not actively managed and are subject to risk similar to stocks. Shares are not FDIC insured, may lose value and have no bank guarantee.

Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities, including, but not limited to: greater market volatility, the availability of less reliable financial information, higher transactional costs, taxation by foreign governments, decreased market liquidity and political instability, among others.

The Fund is also concentrated in the wind energy industry. This involves risks, including, but not limited to: the wind energy industry can be significantly affected by obsolescence of existing technology, short product cycles, falling prices and profits, competition from new market entrants and general economic conditions, among others. The wind energy industry can be significantly affected by fluctuations in energy prices and supply and demand of alternative energy fuels, energy conservation, the success of exploration projects and tax and other government regulations. Wind energy industry companies could be adversely affected by commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources, technological developments and labor relations.

Investing in securities of small and medium capitalization companies involves greater risk than is customarily associated with investing in larger, more established companies. Please see the prospectus for more complete risk information.
