A problem with being an early adopter is that sometimes you’re left with a product that has been rendered obsolete and out of date by its future iterations. This isn’t a big deal if you have the money to keep upgrading to newer versions, but unfortunately this can’t be said for wind turbine installations. While wind turbines are used as a green alternative source of energy, they aren’t very efficient and usually requires possibly thousands of turbines in order to equate to a single coal-fired plant.
