Last month, I met an obstetrician in India and in the course of conversation, asked her how many babies she had delivered.
“After ten thousand babies, I stopped counting,” she said.
Naturally, I was curious to know if anything scared her when she’s delivering a child. Her answer: “I pray that there is electricity for sterilized water and other equipment during the process.”
The obstetrician is also the project director for part of a World Bank health project in Nagaland—a remote Northeastern state in India. She is an ardent advocate for the expansion and promotion of solar energy in the primary health care sector because she, like many of her colleagues, believes that more solar energy in the health sector can spur a revolution by boosting the standard and reliability of health delivery services in the country.
When I joined the World Bank four months ago as a renewable energy specialist, I had always considered solar in the context of electricity for homes and businesses. But working with other sectors and exploring solar interventions in increasing crop productivity, safe drinking water and child delivery in health centers has shown me the massive potential solar energy has to help other areas of development as well. There is a clear business case for why solar is fast becoming a mainstream technology for providing power even in non-energy sectors like agriculture and water.
Until recently, the biggest hurdle in adopting solar power was the high upfront cost (more than $3 per watt before 2010) and lack of project financing for solar projects.
But much of that has changed. In the last four years, solar module prices have fallen more than 70% (less than $1 a watt), and per unit cost of solar power (kwh) has fallen from 30 cents per unit in 2010 to less than 8 cents per unit not only in India but also in Brazil, Chile, UAE and other countries.
