Assessing the Value of Small Wind Turbines
NY Times ^ | September 4, 2008 | KATE GALBRAITH

SAN FRANCISCO — With the California blackouts of 2001 still a painful memory, Chris Beaudoin wants to generate some of his own electricity. He marveled the other day at how close he is to that goal, gazing at two new wind turbines atop his garage roof. They will soon be hooked to the power grid.

“I don’t care about how much it costs,” said Mr. Beaudoin, a flight attendant with United Airlines. That would be $5,000 a turbine, an expense Mr. Beaudoin is unlikely to recoup in electricity savings anytime soon.

No matter. After shoring up the roof and installing the two 300-pound, steel-poled turbines in January, Mr. Beaudoin found himself at the leading edge of a trend in renewable energy.

Fascination with wind turbines small enough to mount on a roof is spreading from coast to coast. Mayor Michael R. Bloomberg of New York last month proposed dotting the city with them. Small turbines have already appeared at the Brooklyn Navy Yard, atop an office building at Logan International Airport in Boston, and even on a utility pole in the small New Hampshire town of Hampton.

Wind Turbines Span a Vast Size Range

Jodi Hilton for The New York Times
Turbines at Logan International Airport in Boston produced fewer kilowatt hours than anticipated in May and June.

Noah Berger for The New York Times

Wind turbines installed atop a new building in the Brooklyn Navy Yard. The canopies stretched overhead act as a bird shield.

These tiny turbines generate so little electricity that some energy experts are not sure the economics will ever make sense.

If small wind turbines are not economically viable, just make the utilities purchase the excess power. The utility companies need another mandate. These wind turbins will make many lefties feel good so no expense or mandate is too small.

But Biden is a BIG wind turbine. ;^)

Well here in sunny California, solar electric is close to making economic sense. I currently pay approximately 37 cents a kWh for the majority of energy I use. The payback time is about 10 years with current available technology. When the payback time gets down to less than 7 years and the life expectancy exceeds 15 years it is worth while doing I think. At 10 years payback the life expectancy is a big gamble.

Perhaps if large fans were mounted in front of the turbines for when the wind doesn't blow....Well the man said he didn't care what it cost to produce wind energy! And it did work in that old Popeye cartoon.

The latest environmental research about bat deaths near wind turbines implies that wind turbines cause a sudden air pressure drop immediately down wind of the turbine. Some environmentalists (don't shoot the messenger) are saying that this causes massive bleeding in the lungs of the bats and that wind turbines must be turned off at night when bats fly to protect bats and the environment.

I kid you not!

There needs to be a new law of science that says that environmentalists will object to any promising energy technology, if given enough time and research money.

My thermo-syphonic solar water heater had a 20 year warranty. The contractor went out of business a year after it was installed. It gave me all the hot water I needed from March to October independent of the gas water heater. October through February it functioned as a good pre-heat before a natural gas boost. That was fine until the storage tanks failed after 5 years. The hard water in San Diego corroded the tanks, wetted the insulation and made the system unusable. It NEVER paid back even 5% of the investment...even considering the significant tax credit against the initial acquisition cost. Defunct companties don't honor warranties. I paid to have the storage tanks transported to the local dump. The solar collectors were picked up gratis by a local contractor as spare parts for a few remaining customers with functioning systems. It was a terrible "investment".

My bad—should’ve paid closer attention to that article about how “blown away” McCain was by the incredibly clever comments Biden made in his presence on that airplane ride today. I mean it left McCain’s response looking stiff and falling flat!

Yes. Solar electric doesn't have the same problems as heating water but there are still wear and tear issues. Any system like that needs a proven track record under actual user conditions, not a calculated guess. That's why I'm not willing to take the chance with a 10 year payback period. Too much can happen over that long a period.

Yes, 10 years is a long time and that time frame was provided by the one selling it, and it may be closer to 20 years, and it may be supplanted by new technologies. It is much too soon
for me to invest.

MY AIRCONDITIONAR MAKES MY HOT WATER. WORKS GREAT HERE IN

SOUTH FLA. IN THE WINTER I ONLY TURN ON MY HOT WATER

HEATER 30 MIN. BEFORE I USE IT. THEN TURN IT OFF. HAS

WORKED O.K. FOR THE LAST 25 YEARS.

In the 80's I worked as an engineer at PacBell. Part of my tasks was to run an economic analysis with a tool called CUCRIT. The general rule of thumb of most projects was a "discounted payback period" of 5 years for a viable project.

The economics on my solar hot water heater depended on natural gas prices skyrocketing and the equipment lasting the stated warranty period. Both premises failed. My 2008 Mercury Mariner Hybrid came with a promised $3,000 tax credit. That made it a wash vs the simple gasoline engine. The tax credit came in at $1202. More lies from the government and manufacturer. The MPG was supposed to be 28-32. Best case has been aroudn 27.2 MPG in fair weather, 21.2 in the winter. Barely better than the simple gasoline engine, while losing the towing capability in the 2003 3.0L V6 Escape. It wasn't a "win" economically either. The saving grace has been the heated leather seats, built-in NAV/GPS and Sirius satellite radio. I'll happily purchase those accessories in my next vehicle, but it will be a simple gasoline engine with some tow capability.

I missed that article. Are you sure it didn't say McCain was board stiff and flat lining from Biden's unending drone?

Joe is a sustained wind but he always lacks real power. Ole Topical Depression Biden huffs and puffs but you know he'll never make it to Category 1. The problem with harnessing Joe Blow for practical use is you never know where he's going to go. One minute he's blowviating about how smart he is the next he might be knocking down a 7-11 store full of immigrants. Joe is an ill wind that will never be a really hairy storm but he'll keep plugging along stealing all the air in the room.

Along with solar etc, they make great sense for living “off grid.” They open up millions of acres in the boondocks to “first world” living standards.
