New technologies, which we introduce, may be feasible, but not cost effective. The funds may not choose among them wisely. Interest in achieving a clean environment may diminish.

Government policy and community views, as well as concerns and concepts change. We try to change with them. New technologies appear and we try to identify them right away.

Because of market conditions and the need to make choices, we may not be able to invest in all interesting technologies or bring the most promising products all the time.

Potential advantages of alternative energy may be slow in development and recognition.
