Dharnai, a village nestled in the heart of Bihar, used to be off the grid, hidden from the public eye and in oblivion for more than 30 years. The population of the village would face several hardships of energy deprivation as they relied on firewood and paraffin candles in the absolute absence of power. However, Dharnai came to be India's first solar powered village in 2014, marking a shift from being a decrepit old village to a shining example of sustainable growth. This incredible journey of the village from darkness to light is nothing short of commendable providing insights into how renewable energy might be used to electrify rural areas.
The 2,400 people who resided in Dharnai were without electricity for over three decades. Conventional power grids avoided the village even though it was close to Bodhgaya and had basic social infrastructure including schools and medical services. As there was no power, the sun's motions determined everyday activity. The society relied on dangerous fuels like kerosene and firewood for cooking and lighting, women were constrained in their home responsibilities, and children rushed to finish their studies before dusk. These behaviours restricted access to economic and educational possibilities in addition to posing health hazards.
Acknowledging the urgent need for sustainable energy solutions, Greenpeace India launched a ground-breaking project in Dharnai in partnership with the Centre for Environment and Energy Development (CEED) and BASIX, a livelihood development organisation. With an estimated INR 3 crore investment, the project was started on July 20, 2014, with the goal of establishing a decentralised renewable energy system (DRES) to power the entire hamlet. A 100-kilowatt (kW) solar power plant that would supply Dharnai's homes and businesses with continuous electricity was the project's focal point. With its battery backups, the system provided power around-the-clock, which was a big change from the village's protracted darkness.
Dharnai saw significant changes after solar power was introduced. Children would be able to read beyond daytime hours with enough lighting, which would enhance their academic performance and goals. 60 solar-powered lighting were installed to improve nighttime visibility and enable residents—particularly women—to move around safely after dark. Economic growth was boosted by electrified houses and businesses, which allowed stores to open later and new businesses to start. Farmers were able to consistently obtain irrigation thanks to solar-powered water pumps, which improved crop yields and allowed for a wider variety of farming techniques. By switching from firewood and kerosene to clean energy, indoor air pollution was decreased, which in turn improved environmental sustainability and decreased health problems.
Dharnai has established itself as an example for sustainable rural development as a result of its successful switch to solar energy. Without depending on traditional power grids, the experiment showed that decentralised renewable energy systems could successfully meet the energy needs of isolated populations. In addition to guaranteeing energy security, this strategy gives communities the ability to direct their own growth. Interest in applying comparable concepts to other energy-poor communities in India has increased as a result of the successful results in Dharnai.
Although Dharnai's change is admirable, there have been difficulties along the way. The success of the project drew interest from a number of stakeholders, sparking discussions over the sustainability and scalability of such models. Ongoing issues also include ensuring the solar infrastructure is maintained, and educating the locals on how to operate the system. But the Dharnai campaign has sparked a wider discussion about the value of community-driven solutions and the role of renewable energy in attaining universal electrification.
