When you think about it, it does make some sense – but did you know WIND Farms change many expects of the environment down wind. The concern is this technology for energy is growing in popularity, the installs are getting bigger and what will the environmental outcome be?
The temperature that defines the weather in a region is the surface air temperature below the atmospheric boundary layer. In this paper, the authors used data from wind farms in San Gorgonio, California to show that near-surface air temperatures downwind of the wind farm are higher than the upwind regions during night, while they’re cooler during the day.
Many wind farms are built over agriculture land, so the turbines can actually have beneficial effects, such as the nocturnal warming of ambient air to protect crops from frosts. But as wind farms become larger, the complete environmental cost and possible unintended consequences of these temperature shifts must be considered to ensure the sustainable use of the wind.
As will many other forms of natural energy collection, we make changes to the natural state of things which effects many other things at the time we don’t realize. Very interested stuff!
This article looks at a new method of positioning the turbines to minimize the temperture change down wind.
