And who is going to pay for millions
acres of blight.
To estimate the impacts of wind power, Keith and Miller established a
baseline for the 2012‒2014 U.S. climate using a standard
weather-forecasting model. Then, they covered one-third of the
continental U.S. with enough wind turbines to meet present-day U.S.
electricity demand. The researchers found this scenario would warm the
surface temperature of the continental U.S. by 0.24 degrees Celsius,
with the largest changes occurring at night when surface temperatures
increased by up to 1.5 degrees. This warming is the result of wind
turbines actively mixing the atmosphere near the ground and aloft
while simultaneously extracting from the atmosphere’s motion.
So, a sufficient quantity of wind turbines would actually *cause* warming.
And for solar:
Previous studies have shown that both solar arrays and wind farms have
the potential to cause regional changes in temperature and precipitation
by altering the amount of solar radiation absorbed by the Earth or
disrupting local airflow patterns.
Solar panels change the way sunlight is reflected and absorbed by the
Earth. Any radiation they take in is radiation that’s not being absorbed
by the Earth. This leads to a cooling effect in the region surrounding
the array. In fact, the first two simulations in this study, which
assumed solar panel installations throughout the world’s desert and
urban areas, produced a 2-degree Celsius regional cooling in the desert
regions. This cooling was also associated with a 20 percent decrease in
precipitation in the deserts. Other, slightly broader changes in
precipitation and wind patterns occurred as a result in the regions
surrounding the deserts.
In the first simulation, the average change in global temperature is an
average decline of about 0.34 degrees Celsius, relative to the
temperature that would be expected under the same low-carbon climate
scenario with no solar parks. In the second simulation, where the heat
island effect is taken into account, there would be an average increase
in global temperature of about 0.09 degrees Celsius.
