India’s wind power potential declining due to global warming change, says study

Ironically, the ungrateful climate responds to attempts to ‘save’ it by offering less reward to its supposed saviours. Unfortunate perhaps, but relying on weather-dependent power always will carry risks.

The warming of the Indian Ocean due to global climate change may be causing a slow decline in India’s wind power potential, according to a study, as Financial Express reports.

India, the third largest emitter of greenhouse gases behind China and the US, is investing billions in wind power and has set the ambitious goal to double its capacity in the next five years, said researchers from the Harvard John A Paulson School of Engineering and Applied Sciences (SEAS).

The majority of wind turbines are being built in southern and western India to best capture the winds of the summer Indian monsoon, the seasonal weather pattern then brings heavy rains and winds to the subcontinent.

The study, published in the journal Science Advances, found that the Indian monsoon is weakening as a result of warming waters in the Indian Ocean, leading to a steady decline in wind-generated power.

“We found that although India is investing heavily in wind power to tackle climate change and air pollution issues, the benefits of these substantial investments are vulnerable to the changing climate,” said Meng Gao, a postdoctoral fellow at SEAS and the Harvard China Project.

The research calculated the wind power potential in India over the past four decades and found that trends in wind power are tied to the strength of the Indian Summer Monsoon.

In fact, 63 per cent of the annual energy production from wind in India comes from the monsoon winds of spring and summer, researchers said. Over the past 40 years, that energy potential has declined about 13 per cent, suggesting that as the monsoon weakened, wind power systems installed during this time became less productive, they said.

    All very confusing. We are told that warming resulted in increased monsoon activity and extra flooding etc. ie catastrophe. Ah well perhaps not!
    I suppose they will now have to increase the subsidies and dig up a bit more coal.

    So wind is seasonal. Whatcha gonna do for electricity in fall and winter?

    Well at least they will have the Adani coal mine in Queensland’s Galilee Basin to provide good quality energy coal for a few decades. The mine, which the Greens have held up got a decade with every trick in the book, has finally jumped all the hurdles and will start construction, opening up a vast new coal-rich area, for which several other mining companies have been waiting. Almost certainly all this coal will be exported, as our ‘conservative’ federal government shows no sign of repealing the insidious RET legislation which subsidises intermittents in favour of reliable power sources far into the future. The Indian company involved is not stupid – they own the generators that need the coal, so owning the coal mine as well reduces a whole lot of long term risks for them. Perhaps the wind farm plans are just international subsidy farming?

  5. Graeme No.3 says:

    I thought that monsoon failures in India were associated with cooler conditions. Perhaps we should refer to the Goldilocks explanation.
    This ocean is too hot, so no wind power today.
    This ocean is to cold, so no wind power today.
    This ocean is just right, so why isn’t everyone using wind power today?

    Study finds widespread decrease in wind energy resources over Northern Hemisphere
    07 December 2018

    A study by a team from the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences and their collaborator from Purdue University has revealed a widespread decline in wind energy resources over the Northern Hemisphere. Using station observation data, the researchers found that approximately 30%, 50% and 80% of the stations lost over 30% of the wind power potential since 1979 in North America, Europe, and Asia, respectively.

    Their paper is published in the journal Energy.

    The study also revealed that global climate models (GCM) cannot replicate long-term changes on wind energy, indicating wind energy projections based on GCM simulations should be used with careful consideration to the model performance.
