KEY POINTS

·        India has shown leadership in facilitating the Paris agreement, and making what then appeared a highly ambitious voluntary national commitment.

·        This was followed by setting up the International Solar Alliance. The National Solar Mission was launched in 2010 with the target of generating 20,000 MW of solar power by 2020-22.

·        It is time for India to move on to achieving net carbon neutrality. From the outset, India’s position on climate change has emphasised the per capita principle; on grounds of equity, every human being should have the same right to emit carbon dioxide.

·        Electricity from solar and wind is now cheaper than all other sources. It, therefore, makes commercial sense to exploit the full wind power potential, and not to burn any coal for electricity.

·        Solar thermal power with storage offers great promise. Heat from the rays of the sun are reflected through giant mirrors, and concentrated to heat molten salt. The heat trapped in the molten salt is then used to generate electricity at night through a conventional turbine.

·        India could start building a few such plants, with competitive tariff bids, which have helped lower costs for conventional solar power. The same could be done with battery storage. A good beginning is being made in Andaman.

·        Transport is the next largest contributor to carbon emissions in India. Electric vehicles have zero carbon emission of their own. As the carbon emission per unit of electricity declines, and finally becomes zero, carbon emissions from electric vehicles, too, would become zero.

·        The Railways are, fortunately, moving towards full electrification as it makes good commercial sense. Thus, surface transport in the country could, as of now, become nearly carbon neutral with no significant additional cost.

·        The major industrial sectors, such as steel, cement, and petrochemicals, pose technological challenges along with cost and competitiveness issues in moving towards zero carbon emissions.

·        Indian industry is becoming more energy efficient, and would be well poised to move towards lower carbon emissions along with global industry.
