Maui Electric Co.'s sales, measured in kilowatt-hours, are down nearly 10 percent this year, a drop that tracks closely with declining visitor arrivals, said company President Ed Reinhardt. Before the island's economic downturn and fewer visitors coming to the island, MECO had been forecasting that it would need its next increment of firm power generation in 2011. Earlier this year, because of declining demand, it revised that forecast to 2014.

With its ocean breezes, ample sunlight, pounding waves and a continuously erupting volcano, Hawaii seems blessed with the means to produce clean electricity and achieve energy independence. But that isn't anywhere close to happening. For one thing, the technology isn't quite ready. The big drawback with wind and solar energy, for example, is that the flow of electricity stops when the breeze dies down and the sun sets. Since there is no good way to store the power for use later, homeowners need conventional electrical service - meaning fossil fuel-burning plants - as a backup.

Down a dirt road on America's southernmost island, 16 windmills tilt their sleek blades toward the ocean, as dependent on the whims of Hawai'i's tropical breeze as residents are on the electricity they help produce. The Hawi wind farm on the Big Island makes clean and affordable energy, but the 100-foot-tall wind turbines stop when the air is still. Most forms of renewable energy face a similar difficulty nationwide - they're cleaner than oil and coal but fall short on reliability and convenience.

I'd like to share some thoughts on wind energy with you. My problems with wind energy have been the same for 40 years and little has changed to modify any of this. After 40 years of heavy subsidies, dedicated government research programs (wind mills just aren't that complex), wind energy is still a small marginal source of unreliable energy. Even with government mandated Renewable Portfolio Standards (government edicts, not free markets), which force the utilities to buy this costly energy, the problems are more costly and the engineering problems remain.

Whether in the workplace, the home, or the vehicles which move us, electrical demands are increasing even as we use it more efficiently. Both memory chips and power chips are getting larger and more powerful. Even our vehicles are becoming more electrified from bumper to bumper. The trends will continue. This future will need large amouns of highly controlled, reliable, and purified electricity to help the U.S. economy remain productive. Wind energy is the antithesis of such energy needs.

There is this enormous and dangerous assumption embraced by the Governor [of Hawaii] that "renewable" energy sources will save the day.

Even if wind turbines were built in Hawaii, excess capacity would have to be built to handle peak loads in the event that the winds weren’t blowing or the islands would experience brown-outs or black outs. The fact that the periods of highest demands would coincide with a drop off in wind speed means wind turbines cannot be counted on the meet peak load demands in Hawaii. So electrical generating capacity would have to be built twice, first as wind turbines and second as backup peak capacity protection.
