...and produces 100,000 mwhr in 20 years.

Theoretically...

The harsh reality is that 1) lack of wind and 2) being offline for maintenance downtime, mechanical failures, etc. means many won't get there.

Can you show me a 1.5 MW turbine that has been running for 20 years?

Care to read the rest of my responses, since you "quit right there", and reply?

You misunderstand the numbers I cited. I factored in average wind conditions and average windmill production, downtime. Ge 1.5 mw wind turbines are 99 percent available meaning they are not down for maintenance more than 1 percent of the time.
