Even as Vietnam has Southeast Asia's largest installed solar and wind power capacity, coal will continue to be the country’s primary source of energy till 2030.

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?
