Examine the potential of wind energy in India and explain the reasons for their limited spatial spread.

Topic: World's Physical Geography. Syllabus: Salient features of world’s physical geography. Same official PYQ from year-wise 2022 and World's Physical Geography.

Revision summary

NIWE maps strong onshore wind in Tamil Nadu, Gujarat, Karnataka, Maharashtra, Rajasthan, and Andhra Pradesh. Offshore potential is large but still little built. Turbines stay clustered because wind density, land, forests, and evacuation are uneven. Early policy and substations locked in those corridors. Hybrids and offshore can widen the map; they cannot put a farm in every district.

Model answer

Copper italics in this answer — like this — are the key facts. Each one is unpacked in the Facts & figures rail.

Introduction

India has a large wind resource on western and southern corridors, mapped by the National Institute of Wind Energy. Installed capacity is serious, yet turbines cluster in a few states because wind, land, and the grid do not spread evenly.

Body

Potential

  • NIWE’s wind atlas shows strong winds along Tamil Nadu’s Palghat gap, Gujarat’s coast and Kachchh, interior Karnataka, western Maharashtra, Rajasthan, and Andhra Pradesh.
  • Onshore potential is the present workhorse; offshore estimates for Gujarat and Tamil Nadu are large but still early in deployment.
  • Wind matches evening and monsoon pulses in some belts, which can complement solar’s daytime peak if the grid can take both.
  • Manufacturing and a long private-sector history since the 1990s make wind a mature Indian renewable, not a pilot toy.

Why spatial spread is limited

  • Mean wind power density is high only in corridors; the eastern plains, interior north, and much of the north-east are weak for utility turbines.
  • Land for large rotors is scarce near cities, and forest or agricultural objection blocks many otherwise windy ridges.
  • Grid evacuation, until recent green corridors, lagged in new districts, so developers stayed where substations and old farms already existed, as at Muppandal.
  • Intermittency needs balancing power and forecasting; weaker state utilities hesitated to add remote wind.
  • Policy and renewable purchase history favoured early movers such as Tamil Nadu and Gujarat, which locked in a clustered map.

Way forward for spread

  • Hybrid wind–solar parks, better forecasting, and offshore pilots can widen the map without pretending every district is Denmark.

Conclusion

India’s wind potential is real on western-southern corridors and in offshore estimates. Limited spatial spread follows the wind itself, land and forest limits, and a grid that grew around the first farms rather than around every state equally.

"The centre of global trade is gradually shifting from the Atlantic region to the Indo-Pacific region." Examine this statement.

World's Physical Geography

• The global center of economic gravity has decisively shifted from the Euro-Atlantic axis to the Indo-Pacific. • The rise of China, Southeast Asia, and India as primary manufacturing and consumption hubs drives this transition. • Vital maritime chokepoints like the Malacca Strait serve as critical arteries for global energy and merchant trade. • Mega free-trade agreements such as RCEP and IPEF have established new regional trade and rule-making architectures. • Post-pandemic supply chain vulnerabilities have accelerated diversification strategies like 'China-plus-one' and 'friend-shoring'. • Control over critical mineral supply chains powers the ongoing digital and green energy transitions in the region. • Sustaining this geo-economic shift requires robust multilateral frameworks, freedom of navigation, and rules-based maritime governance.

Compare the Loo, Chinook and Foehn winds with respect to their regions of prevalence, their nature and climatic impacts.

World's Physical Geography

• Local winds like the Loo, Chinook, and Foehn are driven by distinct regional pressure gradients and orographic barriers. • The Loo prevails over the Indo-Gangetic Plain, the Chinook along the Rockies' eastern slopes, and the Foehn across the northern Alpine valleys. • The Loo is a scorching, dust-laden convective surface wind generated by intense summer continental heating. • Both the Chinook and Foehn are warm, dry katabatic winds formed via rapid adiabatic compression on the leeward sides of mountains. • The Loo induces severe agricultural stress, crop wilting, and high health risks like heat strokes in South Asia. • Chinooks act as 'snow eaters' in North America, rapidly melting winter snowpacks and opening up pasturelands for grazing. • Foehn winds accelerate Alpine snowmelt, which simultaneously triggers hazardous avalanches and elevates regional wildfire risks.
