Renewable Energy – Our Future!

Day 3: The day began with a lecture by Dr. PBL Chaurasia, Principal,VyasEngineeringCollegefor Girls,Jodhpur, on the scope of renewable energy sources, with a focus on solar energy. Dr. Chaurasia has carried out research at Fuel Cell Laboratory,UniversityofBermingham.

We learnt that while India has 17% of the world’s population it has an electricity consumption of 2%. At present,Indiahas an installed capacity of 1,85,500 MW and the National Solar Mission envisages to achieve solar power of 20,000 MW by 2020. According to Dr. Chaurasia, “Thar Desertalone has the solar potential to meet the entire power requirement of the country.” He introduced us to various innovative solar devices like solar candle making machine, solar still, solar PV pump and integrated solar device (heater, cooker, dryer combined). We also came to know about an innovation called passive cool chamber- a refrigerator which runs without electricity (Rs. 5000). It works on the principle of evaporative cooling, keeping the vegetables and fruits fresh for 3-5 days and milk products for 3-5hrs.

For the next session, Mr. Vikas Balia a corporate lawyer spoke about industrial pollution and economic growth. He began by speaking about the textile industry of western Rajasthan, and how the hand processing units use harmful chemical dyes which the treatment plants are unable to treat. However he felt that, “Conservation without growth holds no meaning; shutting down industries is not an option, they may just shift to another place.”

He observed that currently there is market failure in allocating resources efficiently. So, he advocated technology led solutions and an equitable distribution of cost for environmental conservation. Along with this, Mr. Balia proposed that policy makers should adopt a holistic approach and that law should be aligned with economics, to do away with regional imbalances.

In the afternoon it was time to visit a recharge well (beri) in Judia. We were accompanied by a camel which caused much amusement to the champions! 

Next we visited Suzlon’s monitoring station at Balesar to learn about wind turbine generators (WTGs). The station monitors the 91 WTGs owned by various companies that generate a cumulative power of 140 MW. We enquired the cost and found out that 1MW WTG amounts to roughly Rs. 6 crore with an operational cost of Rs. 15,00,000-16,00,000. The power generated is fed into the state grid and the companies are paid for it by the government. We felt very fortunate to visit one turbine, equal in height to a 25 storey building.

Some myths were dispelled here, such as wind turbines cause noise pollution and being the cause of death for birds.

The surrounding picturesque landscape at sunset provided the perfect ambience to retrospect on the day’s learning.
