Enercon will produce wind turbines through contract manufacturing
  • The answer is blowin’ in the wind

here is a great need to utilise the free natural resources available to their full potential, according to wind energy experts. India’s excessive dependence on coal, which contributes over half of the country’s energy requirements, is one of the root causes of global warming.

India, says Dr. P.K.C. Bose, vice chairman and managing director of Enercon Windenergy Pvt. Ltd, is the fourth largest market in the world for wind energy, with an unlimited potential for expansion. The country was growing well in wind energy till 2016; but this industry nearly collapsed the following year, he points out. The installed wind energy capacity needs to be greatly enhanced to play a key role in combating climate change.

New and renewable energy minister R.K. Singh’s recent unveiling of a Real Time Market (RTM) in electricity has finally placed India in the global league, providing an organised market platform for buyers and sellers all over the country to meet their energy requirement closer to real-time operation, Bose says; the recently signed Indo-Danish agreement is also evidence of the government’s commitment to renewable energy production, mobilisation and usage.

Enercon India, a subsidiary of the Germany-headquartered wind turbines major, will produce advanced technology turbines through contract manufacturing. Here, it is exploring the possibilities of working with Indian MSMEs to provide them with technology, training and long-term contracts to manufacture critical components like generators, blades, tower and sub-assembly exclusively for its use. It is also setting up its own generator plant in Erode in Tamil Nadu, with the aim of making India its global sourcing hub for turbines.

Among other ways to control climate change is the use of advanced lightweight materials to replace steel and metal. The use of Carbon Reinforced Concrete (CRC) in construction saves time, money and energy, as well as reducing global warming. The Technical University in Dresden, Germany, has found that CRC doesn’t corrode and can last for more than 200 years, while reducing carbon dioxide emission by over 70 per cent. It is also totally recyclable.

The automotive industry, too, can help reduce global warming by using renewable energy as a source for production, and using light-weight materials like glass and carbon instead of the traditional steel and metal. This composite can make a bus or truck lighter, stronger and fuel-efficient, which itself would compensate any additional cost. This weight reduction also leads to a direct cost saving, enabling a higher payload, better fuel efficiency and longer life because composites do not attract dust or corrosion.

Building railway coaches, ships and boats using advanced composite materials also reduces carbon emission; while the aeronautical industry, for its part, is already cutting carbon emission by using carbon fibre or composite on a large scale.

All this will help us leave a cleaner world for the next generation, Bose adds.
