India has invested heavily in renewable power like solar and wind, but new studies suggest that the power production will decline severely in the coming decades due to climate change.
A study published in the journal Current Science suggests that the change in weather patterns and decline in sun’s radiation due to increased cloud cover will result in a significant decline in the production of renewable energy by 2050, the study was conducted by the Indian Institute of Tropical Meteorology (IITM), Pune.
It uses climate models to predict future wind speeds and solar radiation intensity. India was divided into seven regions for the purpose of the study–the Gangetic plains, eastern, south-eastern, south, western, north-western and central India. Western regions show a decrease in both wind and solar capacity, north-western region which is a hub of solar plants showed a decline in solar radiation because of air pollution. Wind analysis shows wind speed slowing in offshore regions and increasing in onshore regions, with an exception of Gangetic plains which shows an increase in wind speeds.
“We have tried to show the difference between historical climates and the future scenario. All the models show an overall decrease in wind and solar power generation potential in India,” said Parthasarathi Mukhopadhyay, a scientist at IITM.
