Climate change will cause wind farms to eventually get less efficient, say researchers

Wind turbines towering over the landscape

This doesn’t seem to tie in with alarmist claims that warming will make hurricanes worse. Note there are several contentious assertions and assumptions about present and future climate in this report, i.e. it’s aimed squarely at man-made global warming believers. But it’s not too hard to see through their spin.

Warming is causing wind farms to get less efficient in the amount of power they can generate and it is bound to get worse, says the IB Times.

Climate change will cause wind farms to eventually get less efficient because the warming planet is changing the way wind currents move around the globe. Winds that traverse the northern hemisphere are more likely to be affected by this, and it is only going to get worse, according to two studies.

With the planet getting warmer every year and emission control measures coming in slower than the damage caused, wind and solar are among the most sought after strategies in the reduction of fossil fuel usage, one of the largest causes of carbon emissions.

The wind, however, might not continue to blow as it does now.

One of the studies by climate change researchers at the University of Colorado at Boulder has found that the warming planet will cause winds to slow down, according to a report in Popular Mechanics.

Lower wind speeds are expected to take over most parts of the northern hemisphere and the drop in energy output in farms across the US, Europe and China will be felt in as little as 10 years, notes the report.

Differences in hot and cold spots all over the planet, caused by the sun’s heat, make particles flow from regions of high energy toward regions of low energy. The cold and hot spots are regular and balanced in such a way that wind is predictable and certain places on the planet have strong winds that are consistent enough to be used as wind farms. “We can’t assume that the baseline wind energy resource is a constant,” said Kristopher Karnauskas, the first author of the study.

The study found that by 2100 potential wind energy in the northern hemisphere’s middle latitudes will drop from 10 to 40%. In central US, this drop is estimated to be in the eight to 10% range by 2050. The estimates are based on whether the world takes up a low or high greenhouse gas approach.

“What we found is that global warming will reduce the wind energy resource across much of the northern hemisphere, especially in the central US,” Karnauskas added.

    Ah yes, it has to be warming of the climate brought on by all those dreadful people driving fossil fuel powered cars, the fact that the monstrosities take energy from the wind must not be looked at lest the green movement ends up hoist by their own petard.

    I have yet to see a bandwagon pushed by the green lobby that doesn’t have so many unintended consequences that it should never have got to the planning stage let alone implementation. But then what else can you expect from the church of climatology where feelings far outweigh facts.

    I thought we were building wind farms so it doesn’t get warmer? If we are going to have all the change anyway, why bother building them?

    [reply] indeed

    Because the, the farmers, are in full blown denial of science that has been proven. For decades family farms, when tree rows were popular for keeping the wind off the ground, people on the ground noticed less wind. Those that needed water pumped, raised windmills above the trees and caught the wind. And they noticed, that wind patterns changed. Same as the weather. It changes. The smart farmer found other ways to water their crops. But, to produce power, you have to lie and cheat to get money 24×7. Make it law, you get paid for not producing.

    Wind not working? How about coal…

    Date: 14/12/17 Reuters

    The 1,050 megawatts plant in western Germany has been held up for years by intense legal battles with environmentalists as Germany seeks to move away from coal-fired electricity long-term.

    Once they’ve figured out how to keep the lights on and the industries working when it’s dark and not windy, that is 😐

    Can’t trust my memory any more. Am sure I learnt long ago that on a cooling world temperature differential between equator and polar regions increases, thus global winds and climate events increase.
    Been no shortage of wind where I live in South West Wales.

    2. Most Frequent Climate Instability During Global Cooling/Reduced CO2 Periods
    Kawamura et al., 2017

    Numerical experiments using a fully coupled atmosphere-ocean general circulation model with freshwater hosing in the northern North Atlantic showed that climate becomes most unstable in intermediate glacial conditions associated with large changes in sea ice and the Atlantic Meridional Overturning Circulation. Model sensitivity experiments suggest that the prerequisite for the most frequent climate instability with bipolar seesaw pattern during the late Pleistocene era is associated with reduced atmospheric CO2 concentration via global cooling and sea ice formation in the North Atlantic, in addition to extended Northern Hemisphere ice sheets.
    – – –
    Cooling oceans can absorb more CO2 from the atmosphere.

    If indeed some weather events are getting more ‘extreme’, that could be interpreted as a sign of cooling, not warming.

    Effects of climate change on wind power yield unclear, German scientists say

    It’s supposed to happen the other way round :/
