I just published this detailed post on solar pv vs. wind turbines for installations of the same cost:
I'm starting to come to the conclusion that except for a few spots in the U.S. (mostly in AK, HI, or on top of mountains) residential wind will always lose to solar PV assuming optimal locations for both (i.e. no shading on solar panels, no obstructions blocking wind) and the same capital outlay at the onset.
I'm going to work on another blog post highlighting this fact, because it is rarely covered by most news media who don't even know the difference between a kW and a kWh, let alone know how to do the analysis themselves.
What I'm looking for is someone who can tell me I am missing something in the analysis? Any thoughts?
On cloudy days, especially when they are contiguous and numerous, wind will provide greater benefit.
What is the larger question? How flexible are the people (and other entities) involved?
David, did you check out the original post? I'm speaking on an annual basis. Cloudy days don't necessarily mean wind, and solar will still produce electricity even on cloudy days. On an annual basis, I'd be surprised if there were many places where resi wind beats solar.
Nope. I responded to your question. It wasn't serious?
Who lives on an annual basis?
Ok, I didn't word my question effectively. What I meant to say, "Even on a 100 ft tower, does a wind turbine outperform solar on an annual basis" Again, I'm sure there are locations where this is the case, but these are few and far between, and outside of the majority of the U.S. population.
Everyone lives on an annual basis when it comes to analyzing what the better return on energy investment is.
"Everyone lives on an annual basis when it comes to analyzing what the better return on energy investment is."
Then, hopefully, each is very flexible. Lately, fewer and fewer days seem to be average days.
That's a great example. Most people would assume that wind would kick solar's butt in MN. Even if you halved the size of the PV array (and then had the installed cost under the wind cost) it would still produce more kWh than the wind!
