India should invest in creating a competitive solar module sector across the manufacturing chain, from procuring primary resources to the finished product.

According to a recent report, India will need 3, 128 Trillion watt hour per year (TWH) of electrical energy in the future if it adopts a frugal policy for energy use. This annual need could be met through renewable energy sources alone in the form of solar power (photovoltaic [PV] and thermal), wind, and hydroelectric power. But is this change in energy mix really feasible?
