SO, the propaganda/publicity machines promote a California desert solar complex costing 1.6 billion dollars as providing "140,000 households" with power .... Obviously implying that dirty/evil/nasty/carbon-dioxide polluting" regular power plants will not have to to provide any power to these 140,000 households since the solar plant is on-line burning up birds every 2 minutes as it provides power ....

OK. So please put up with the fact that I am prejudiced against the taxpayers providing 1.6 billion dollars in loan guarantees to a group of tax-paid companies to incinerate innocent birds flying over the otherwise pristine deserts of southern California.

Just what is considered a "household" when the publicists write their press release? A full year's of electric power? An averages "per captia" power use times an assumed "people per house" (or apartment) use for a year?

An "ideal" power at "maximum output at noon on a perfect low humidity day on June 22" divided by the "average power per house per day for a year"?

The US Energy Information Agency (as if we needed a government agency to identify energy abbreviaitons) does NOT even list "households" as a item in their list. Nor does anybody else for that matter. The closest is a "study" done for California by a California PhD payee who used

"Total Electricity usage (all applications) per year for comparison:

USA 12,000 kWh per capita

California 8,000 kWh per capita
Average of SC Edison and San Diego Gas and Electric

Household electricity use: 6,000 kWh per household per year for 3 residents average per household. So the household use per capita is 2,000 kWh or about ¼ of per capita electricity from all applications.



Household Natural Gas use: 400 therms per household x 30 give 12,000 kWh equivalent electricity. Since much of the electricity is generated by natural gas, it is not totally unreasonable to compare these two in kilowatt hours. We note that heating water and households by natural gas uses twice the power of household electricity.



Total average household power usage:

6,000 kWh electricity plus 12,000 kWh gas equivalent = 18,000 kWh per year.
"

in one of his analysis for CA to increase subsidies for green energy in CA in 2010.

But even there, in a prejudged study, he could not get a "standard number" for a household.

I see hundreds of times a year, the "number of households" that some given publicity stunt will provide to justify more tax payer subsidies.

But what is this number?
How is any given scheme for green power set up: Maximum potential output at high solar noon on a clear day in mid-summer?
An :average" day at noon in mid-winter?
A cloudy day in October?
A "yearly average day" across the whole year for 12 hours - when a gas turbine is required to pick up the rest of the load burning up its turbine and rotor trying to adjust a rapidly changing load each hour?
A yearly "average" delivery when a wind turbine only has a 21% efficiency rating?
The maximum number of assumed households yearly electric use divided by 365/24 ... then the maximum wind turbine output divided by that "yearly average value" ?
The maximum household loads at 5:30 in the south in July when AC loads are at their maximum?
The hourly load in the north at 22 January when heating bills are highest?

I KNOW it is propaganda. I accept that - our administration and the ABCNNBCBS news media are going to publicize only the "facts" that they want to promote. But ... What is a "US household" and who determines it when they write the propaganda?

However, if you look at the unemployment now, 5.4 million jobs might be more desirable than 60MW of power.

So one could say that a 60MW generator (or wind farm) takes 5,400,000 jobs from American workers. However that's not how the propaganda is written.

And that what this whole subject is about. What is the best way to spin the windfarm angle.

Make up a number and run with it. Just don't make it too outlandish or you will be called on it.
 
Every general interest article I read about a new power plant makes the 'plant output to households served' comparison. Nuke, coal, natural gas, wind, solar, geothermal. It's a straightforward (albeit not 100% accurate) way of explaining unknown units to the average non-technical audience.

More the result of Technical Writing 101 than propaganda.
