McDermott noted that wind power represents about 75% of the renewable energy produced in the United States.  Currently wind is a close second to natural gas for newly installed production capacity.  Like all projects which are capital intensive, wind power construction suffered with the collapse of credit markets.  Some deals are now being done, but on more conservative terms.  Key hurdles continue to be the on-again, off-again government support in the form of tax credits and loans as well as the onerous delays caused by environmentalists. 

Intermittency is the renewable energy term to describe the uneven production of power by both wind and solar.  Dr. Walker stated that as wind power becomes a larger portion of total energy production it should be considered part of the base load with natural gas as the go-to energy to fill in the gaps.  He noted that the bulk of wind energy production in the United States is concentrated in a short list of utilities.  Except for the very largest users, most utilities struggle with understanding how to manage an intermittent supply.

Although the established global wind energy market is huge, the panel felt that it was not mature and therefore there were significant opportunities for new business creation and growth.  Their opinion was that there were vast improvements which will be made in blade design and the mechanics of wind turbines.  They felt that there was a great opportunity for innovation and invention to originate from outside the research departments of the large manufacturers.  As the number of wind turbines proliferates they see an opportunity for companies in the “nuts and bolts” aspects of service and maintenance in a more organized manner than currently exists.

Energy storage in its various forms is a response to the problem of intermittency as well as integral part of an effective smart grid.  James Sahagian said that Sempra Generation has a strong interest in compressed air strorage in spent oil and natural gas wells as a viable means to store energy during those times when wind energy production is greater than immediate demand.

In addition to enXco and Helix Wind, there are 22 other wind power companies listed in CleanTECH San Diego’s database of cleantech companies include Cannon Power, Knight & Carver and Padoma Windpower.
