Identify Gaps in current systems

  • Critical Component supply / FOREX
  • Standards for Grid Connection of WE
  • Issues of Power Quality
  • Lack/Attrition of Skilled Manpower
  • Fly by Night Operators /Quality&AMC
  • Threat of updated technology denial over

long term in the absence Indigenous R&D

  • Land costs and Governmental procedures

www: Win With Wind is NEED of HOUR to Power All, Ever

  • Wind is not mined & use needs MINDSET
  • Wind to hydrogen for mobile-energy
  • Wind is not transported
  • Wind need not be stored
  • Wind is abundant, giving Green Power
  • Wind is freely owned
  • Wind power sustains drinking water
  • Wind is completely renewable by NATURE
slide-26
SLIDE 26
  • No threat of cost escalation
  • No threat of hoarding
  • No threat of transport-driver/ miner’s Strike
  • No threat of depletion as it is renewable
  • No threat of Pollution to environment
  • Wind is sustainable with infirmity managed

with Focused Political and societal WILL

Wind certainly Works

NATIONAL WIND MISSION NEEDED

  • Wind farm cooperatives with farmers as owners

(rural corporate) as in Denmark

  • Societal Will and awareness of long term

sustainability and energy security

  • Sustained Political Will for wind onshore/offshore
  • Sustained Policy directives for extended period

for self-sustained green energy devp.

  • Promotional measures for Capacity building in

India for (offgrid/Wind solar/Grid-tied ) roof top or hill top ( net metering seriously)

  • Augmented Clean energy fund from CSR stream

& Citizens
