Tybee would have to invest an estimated $134,000 in shipping and installation expenses but could save more than $400,000 in electricity costs over the 20-year life of the turbine.

Is it me, or do the savings seem a bit skimpy?

On the face of it, yes. But, if one could borrow $150K@5% over 30yrs, then the loan would be $805/month & the electric "savings" would be $400K/20/12=$1,667/month.

So, it costs $805 a month to get $1,667 a month in savings.

That seems OK, unless there's more to the story [I didn't read the article, but am just going on the numbers presented.]

Do you see an expense item missing from that $134,000 number? It’s way greater than $134,000.
