A strategic approach that could curb global warming

The effects of global warming are already visible. Average temperatures are only 0.8 degree Celsius higher today than in 1880. Yet there is already an increasing frequency of extreme weather events, rising ocean temperatures and disappearing corals, melting glaciers and shrinking polar ice caps, and rising sea levels. Public action has nevertheless been too feeble to cope with this looming disaster.


Paris Accords –

The Economist Magazine cited an estimate by the Inter-governmental Panel on Climate Change that containing the earth’s temperature increase over the 1880 benchmark to under 1.5 degrees Celsius will require a 20% reduction in oil and gas production by 2030. But ExxonMobil alone plans to produce 25% more oil and gas by 2025, and other oil majors are headed in the same direction.

Climate hypocrisy –

  • The oil majors support the Paris accord. They are also among the largest investors in solar power and other renewables. Nevertheless, the roughly $300 billion of annual investment in renewables is just a fraction of the investment being made in extracting more fossil fuels. Why this disconnect between the required investment priorities for containing global warming and the actual investment priorities of energy companies?
  • The answer is that these companies are accountable to their shareholders. Their investments are driven by profitability, which in turn is driven by current and future projections of demand and supply. Fossil fuels like coal, oil and gas are more profitable than renewables and account for 85% of the total energy supply. That is what drives the current shareholder value of oil companies.

Future of renewables –

Looking to the future, the latest BP Energy Outlook (BPEO) projects that even under the most aggressive transition scenario, renewables will account for just about 16% of total energy supply in 2040, up from around 3% today and hydro and nuclear power will account for another 11%. Fossil fuels will still account for over 70% of total energy supply. In fact, the main transition, the BPEO envisages, is a shift from coal to oil and further to gas, not from fossil fuels to renewables. No wonder that oil and gas continue to account for the bulk of investment in the energy sector.

Indian scenario –

India’s energy policy has to be seen in this global context, with two India-specific factors in mind: resource endowments and energy security. India remains heavily dependent on vast reserves of coal, which is also the dirtiest fuel. Hence, India’s long-term strategic interest requires a radical shift from fossil fuels to renewables, including hydropower. But other supporting strategies are required over the medium term.

What could be done?

A strategic energy policy menu could thus include:

  1. Renewables – India should move towards maximum dependence on renewables, given its vast potential for completely clean, radiation-safe and strategically risk-less solar and wind power. Instead of subsidising power prices and distorting energy markets to achieve this goal, tax incentives should be used to maximise investment in renewables.
  2. Coal – Heavy dependence on coal will continue for years, but it should be gradually reduced. Meanwhile, large tax concessions could incentivise investment in clean coal technologies that can significantly reduce carbon emissions from coal-based power plants.
  3. Oil and gas – The shift from coal to oil and gas will further increase India’s import dependence and energy security risk. To minimise this risk, import sources should be diversified further while incentivising domestic exploration for oil, especially gas reserves.
  4. Nuclear power –Though a clean fuel with large expansion possibilities, it carries a high risk of disastrous accidents as seen in Russia, Japan and the US. Given India’s relatively weak regulatory environment, it is best to draw on nuclear power only to meet gaps in supply from other sources.
  5. Hydropower – This is a clean, renewable energy source, though usually not treated as such. Its share of energy supply has declined from nearly 54% at independence to only 11% today. This neglect is inexplicable since only 35% of hydropower potential has been utilised and “run of the river” projects do not require large ecologically damaging reservoirs that also displace people. This readily available energy source is a low hanging fruit that should be exploited to the maximum and at the earliest.
