Default The Power Output of the Palm Springs Wind Farm

I was interested in the power output of the palm springs wind farm so I visited your site to find this information. There is a pretty huge typo in the paragraph about the wind farm. The website says:

"A wind turbine's cost can range upwards to $300,000 and can produce 300 kilowatts an hour - the amount of electricity used by a typical household in a month."

This statement is pretty stupid. A watt (or kilowatt) is a measure of rate, energy per time. Saying "300 kilowatts an hours" is meaningless in this context. Miles per hour is also a rate. Does "300 miles per hour an hour" sound correct? No? Well it's just as correct as saying "300 kilowatts an hour". Probably what you meant to say is just "300 kilowatts".

A watt is a joule per second. A joule is a little packet of energy. When you say "300 kilowatts" what you are really saying is "300 thousand joules per second". When you say "300 kilowatts per hour" you are saying "300 thousand joules per second per hour". The only context that this could make sense in is if you were talking about energy production acceleration, which you are clearly not in said paragraph.

If you were talking about a Corvette you might say that is was capable of speeds around "180 miles per hour", not "180 miles per hour an hour" which is just stupid.

This is an understandable mistake for the non-technical. But leaving it up on your website is making everyone who reads it a little more clueless.

Thanks for your attention to this matter.

The Palm Springs, CA windmill-generator farm looks awesome from I-10. I encountered it on my way to Sunnyvale, CA this past weekend. I do have a question about the information on your website. See details below.

Website information:
"A wind turbine's cost can range upwards to $300,000 and can produce 300 kilowatts - the amount of electricity used by a typical household in a month."

I understand kilowatt as a measure of energy rate (or unit of power) -- not an amount of energy, as it would be implied on you website. Do you mean 300 kilowatt-hours?

Thanks

This appears to be an ongoing topic. What is your take of Robin's understanding in the ealrier post?

Robin's comment is valid to a point. The discrepancy is that "the amount of electricity used by a typical household in a month" isn't measured in kilowatts or kilowatts an hour -- the correct unit is kilowatt-hours. The kilowatt-hour is a unit of energy (not an energy use rate), which would specify an amount of electricity used. A typical residential bill from the power company indicates kilowatt-hours (energy) used over the billing period.

In any case, the windmill generator farm is quite impressive. I hope this helps.
