An Incredible Story of a Family That Made a Forest, an Eco-Village and Lives Medicine-Free

Drive down 45 kilometres southwest from the city of Pune and you will see a beautiful man-made forest in the Sahyadri range. But when Dr. Pravin Chordia bought this property in the year 2000, it was still barren land. The natural forest had been destroyed, despite Sahyadri being a region that receives heavy rainfall. Dr. Chordia decided that this would be the place where he would reclaim his life by getting close to nature.

Dr. Chordia was a general surgeon who ran his own hospital in Pune. But a flourishing career of 22 years still left him feeling disturbed. The illnesses that he saw on a daily basis, the increasing dependency on medicines, and the mad rush of a city that was becoming increasingly polluted – all these made him conscious that something was not right with the way we live. “I felt we are getting alienated from nature, which is catastrophic. We cannot sustain our lives if we continue to throng our cities and shun nature. This feeling was reinforced when my son was diagnosed with asthma. I decided to change things,” he says.

Slowly, Dr. Chordia began realigning himself and his family with nature. They bought 110 acres of land in Velhe Taluka, Dhanep, in the Sahyadri range. They started reforesting this land and planted at least 2.5 lakh trees.


Some saplings were lost to grazing while some growing trees were destroyed in forest fires. But they relentlessly planted more saplings and still continue to do so.

Today, at least 50,000 trees, of more than 1000 species, are alive and thriving in the land as a thick forest. They have successfully reforested 45 acres of the 110 acre land and the tree planting continues religiously.


Dr. Chordia was more than thrilled to have chosen to go the mountain range and plant trees. He now felt more confident of his thought process of going back to the nature. “As a natural progression, I decided to give up my allopathic practice and shut down my hospital. Going back to nature also means giving up the illogical ways of modern medicine. I told my wife I did not want to end my life on an ICU bed but wanted to live a healthy life,” says Dr. Chordia. With this resolve, he decided to experiment with sustainable living by creating an eco-village in their land in the Sahyadri range. They built mud houses out of compressed mud bricks. The family started to grow fresh fruits and vegetables organically here. They also started working together with the local farmers and helped them switch to organic methods of farming. They composted the waste on the farm and generated biogas. Since this was an experiment, they did not hesitate to try out new things. They used the opportunity to learn and experiment with various ways of generating energy. They installed solar panels and looked for other natural ways of energy generation like photovoltaic, gobar gas and solar cooker. They did rainwater harvesting and built ponds on the land. A negligible amount of power is used from the grid and every drop of water is recycled in this eco-village.

They named this place Serene Eco Village, for its beauty and serenity.

The family’s relationship with the place and its people also grew in the meantime. While they encouraged the farmers to take up organic farming, they also made sure that there was a market for the produce. They started procuring the organic produce from farmers and selling it in Pune. They started an agarbathimanufacturing unit, oil pressing unit and medicinal herbs unit to employ the local people.  There is also a school that functions in the traditional gurukul style on the premises.

These activities support over 40 families in the region.


Until recently, Serene Eco Village was only a family experiment. But a couple of years ago, they opened up the Serene Eco Village experience to visitors as an agro-touristic spot.

Living in middle of the forest, learning some organic farming, eating food grown on an organic farm, trekking, and just being close to nature – that’s the agenda for most of the tourists who visit Serene Eco Village!


Dr. Chordia and his family shuttle between Pune and Serene Eco Village. The mountains, the good food from the farm and the natural living have gifted the family a completely different living experience, including that of an impeccably healthy life. The family has not taken any medicines for the past 15 years! Dr. Chordia’s son does not suffer from asthma anymore. Dr. Chordia, who stopped his allopathic practice, is now a proponent of medicine-free living. He runs a free clinic in Pune that guides people on how to live a healthy lifestyle without being dependent on drugs.

At Serene Eco Village, Dr. Chordia hosts people from across the country who want to explore a natural and healthy way of living. He has helped over 2000 individuals live medicine-free lives. He believes that good exercise, healthy living and being close to nature are the best solutions to all the complexities that urban living is imposing on us.

Rooftops – Indian Solar’s New Frontier by Ritesh Pothan

Rooftops – Indian Solar’s New Frontier

Post 2009, Solar has been buzzing with medium as well as large projects and has recently crossed 6500MW at the end of March 2016, though installed capacity with rooftops currently at less than 0.25% of installed capacity. JNNSM and Gujarat projects accounted for almost a GW within a couple of years and propelled India into the big leagues.

This is however in deep contrast to global standards where roof’s account for majority of installations. Below is a chart that defies belief especially since solar is a distributed solution albeit used a centralized one in India to replace coal and fossil fuel dependent plants. Large ground mounted plants bringing with it the hassles of (AT&C) losses currently around 25% estimated to cause approx. Rs. 75,000 crore loss yearly for discoms. So for every 1 KWh generated only 0.75KWh reaches the consumer which isn’t the case with rooftop solar where there is no waste due to Transmission or Wheeling distances and inefficiencies.

Solar roof are a dire need for the nation as it reduces the CAD and brings in energy security to a growing populace desirous of safe, clean and consistent energy to increase the economic growth rate. Every unit of energy delivered is a force multiplier of magnitude in elevating the economic standards of the receiver.

Poor attention has been paid to this method of generation specifically since its not a medium of control or political benefit. Very few states recognize the importance of delivering off grid and independent energy delivery systems that reduce dependence on inefficient delivery mechanisms.

For the nation to grow, it needs to be supported by sufficient infrastructure and incentives to the common man whereas too much attention has been paid to large schemes and not enough to direct delivery. Solar rooftops is one such casualty of a populistic mindset but its undergoing changes a step at a time.

2015 has seen some dramatic changes in policy especially in Karnataka and Maharashtra. Maharashtra a state that refused to have anything to do with solar under the previous government is now looking at a huge target but implementation is still tightly controlled by the state owned generator.

Karnataka launched the most progressive rooftop FIT policy in the country by offering a huge premium for solar rooftop generation and to date has signed rooftop PPAs more than 800 MW in sizes varying from 1 KW to 1MW. Yet due to the greed of locals hawking their offtake agreements just few MWs have been installed.

Gujarat has a rooftop policy but refuses to approve proposals given that it has already met its RPO targets for years, TN, AP, Telangana all are yet to get off the ground.

There is an urgent need to standardize the FIT (Feed In Tariff) across states as well as simplify regulations and procedures. The paltry target achievement of 166 MW is testament to the fact that the current policies aren’t working even sub-optimally. Dependence upon subsidy or government offtake can’t sustain the field on its own, barriers need to be removed, single window clearances with timely subsidy payouts are sorely needed

Another concern is the load shedding in certain states during Solar Generation Peak hours that renders any unused generation wasted especially since load shedding is a daytime phenomenon. The rooftop industry with just 166MW installed across the country is still very nascent and has a long way to go yet with educating the user being the highest hurdle to cross.

SECI is doing its part with the new 500MW Solar Rooftop tender which is pushing solar energy to homes and offices. The Central Financial Assistance (CFA) i.e. Subsidy which was dropped last year has been reintroduced but rightly excluded government and private industries.

Under the TN Chief Minister’s Solar Rooftop Capital Incentive scheme, the Tamil Nadu Government provides a capital subsidy of Rs. 20,000 per kilowatt for grid-connected domestic solar PV systems in addition to the 30% subsidy scheme of the Ministry of New and Renewable Energy (MNRE) of the Government of India. For individual homes or flats, the solar system capacity shall be 1 kW. For residential flats solar system capacity of 5 kW, 10 kW and multiples thereof can be applied for common usage as group application.

Kerala’s 10,000 rooftops was a really innovative scheme which highlighted the distributed nature and advantage of solar, though after that the state has come to a standstill due to certain issues. The current subsidy disbursed is barely above 50% which says a lot given that it’s a prosperous state and yet barely 6000 house’s have installed solar

Almost Rs. 5000 crore has been set aside for Solar rooftops and with the center now moving towards incentivizing the home owner, we should see some movement in this segment. For India to be energy secure, roof based solar coupled with storage is the only viable solution for the future.

Policy for Net-Metering based Solar Rooftop Applications, Madhya Pradesh, 20

MP finally comes up with a draft for rooftop solar albeit lacklustre, just the few provisions below are barely adequate as a plan


Installation of SRPs under the policy shall be exempted from banking, wheeling and cross- subsidy surcharges as per MPERC regulation. The settlement of energy, billing period and settlement period shall be as per the MPERC regulation. The energy generated from the solar rooftop system shall be exempted from electricity duty


SRPs installed under the policy shall not be considered as a “construction activity”, and as such, there shall be no liability of property tax for installation of solar panels on their rooftops or premises.

The equipment purchased for installation of Solar Rooftop projects under this policy shall be exempted from VAT and entry tax as per the exemption granted to these systems under Madhya Pradesh Solar Policy, 2012


All Eligible Consumers can avail Central Financial Assistance from MNRE as per the applicable scheme for Solar PV systems. The nodal agency shall take necessary action for processing the request accordingly.

(REC) Renewable energy certificates, battling declining demand, could be scrapped

Renewable energy certificates, battling declining demand, could be scrapped, officials said. The industry, however, sees a turnaround by 2017-18 and does not want the certificates to meet the fate of carbon credits

The market for these certificates, launched in 2010, crashed last year with over 10 million of them remaining unsold. Last month’s discovered price was Rs 3.5 per unit for solar certificates and Rs 1.5 per unit for non-solar certificates.

These prices are far below prevailing rates of solar and wind power. Of the 9.4 million certificates issued last month, 9.3 million were unsold.

A Supreme Court judgment last year empowered state electricity regulatory commissions to enforce clean energy targets and penalise captive power producers and open-access industrial consumers if they failed to meet them.

Since then 11 state regulators have issued orders, some directly imposing purchase of renewable energy certificates and others rejecting exemptions for not buying them.

Under a renewable energy purchase obligation, electricity distribution companies, open-access consumers and captive power producers must meet a part of their needs through green energy. States or utilities that are unable to fulfill their obligation can buy renewable energy certificates, which represents 1 MW-hour of power produced from a clean source. These certificates, divided into solar and non-solar, can be traded on power exchanges.

Touted as an alternative to carbon credits, the mechanism caught the industry’s imagination with companies setting up projects specially for the purpose.

Wind energy companies were first to jump in, followed by solar power producers and then other sectors like conventional energy, mining and steel. “The scrapping of the certificates could cause damage, given states are moving in the right direction,” said an industry executive.

Strengthening enforcement with proposed amendments in the Electricity Act could increase procurement,” said an industry executive.

He said as more states removed exemptions to the renewable energy purchase obligation, a substantial jump in the price of these certificates could be expected after 2017-18.

“The idea is to reform the certificate regime. Low demand has hurt it and a turnaround will take a while. We will also consider how to tackle defaulters,” an official said.

Around 1,200 projects are under the certificate mechanism with a total capacity of 5,383 MW. If large companies meet even 10 per cent of their renewable energy purchase obligation, a backlog of 17 million certificates will be cleared.
