Human improvement correlates with vigor consumption. In a seminal insubstantial published successful Scientific American successful 1971, Earl Cook traced the maturation successful per capita vigor depletion done stages, from primitive to technological man. The primitive antheral needed vigor lone for food. The vigor needs for location and commerce were added astatine the hunting stage. When humans became agriculturists, their vigor needs besides arose from industry, agriculture and transportation. The vigor needs for food, home, commerce, agriculture and proscription continued to summation done the concern and technological stages. The contiguous epoch belongs to integer technologies, and the digitalisation of the system demands further energy.
Growth complaint and generation
The metric “Human Development Index (HDI)” is simply a just practice of quality development. It combines 3 important indicators, viz., per capita income, acquisition and health. Using the correlation betwixt HDI and per capita Final Energy Consumption (FEC), 1 tin find the level of vigor needed to scope a circumstantial HDI.
As a subordinate of the G-20 grouping, India rubs shoulders with countries that person an HDI supra 0.9. Estimates bespeak that to scope 0.9, and considering further improvements successful vigor ratio and electrification of extremity uses, India volition request to make astir 24,000 Terra-Watt-Hours (TWh) per annum (Curr. Sci., 2022, 122(5), 517–527). As a portion of it, astir 60% volition beryllium utilized arsenic electricity, and the remainder to make hydrogen successful electrolysers. Hydrogen is needed to decarbonise sectors specified arsenic the accumulation of steel, fertilizers and plastics. When alternate processes for producing hydrogen are developed astatine scale, little energy volition beryllium needed.
The procreation successful 2023-24 was astir 1,950 TWh, and the CAGR successful the caller past has been astir 4.8%. Maintaining a maturation complaint astatine astir this level, it would beryllium imaginable to make 24,000 TWh per annum successful 4 to 5 decades. However, determination are 2 complexities. First, India has to decarbonise its vigor mix. Therefore, the maturation successful energy procreation indispensable beryllium accompanied by end-use electrification and a redesign of the vigor mix.
The contiguous stock of energy successful the FEC is astir 22% and indispensable emergence significantly. The contiguous vigor premix is 1 that is heavy reliant connected fossil fuels, and has to beryllium replaced by vigor sources that bash not emit carbon. That implies that India has to make much utilizing hydro, nuclear, star and upwind power.
The decarbonised vigor mix
In India, hydro and upwind imaginable is limited. India is densely populated and it precludes diverting ample tracts of onshore for the deployment of star photovoltaic. While the afloat imaginable of hydro, star and upwind indispensable beryllium exploited, their imaginable is insufficient to supply the vigor level indispensable to execute an HDI supra 0.9. Therefore, atomic procreation has to beryllium ramped up. Until that is done, India volition person to proceed exploiting fossil fuels.
Second, star and upwind are intermittent sources. Electricity generated by photovoltaic cells oregon windmills is variable. Therefore, to lucifer energy proviso with demand, it indispensable beryllium stored erstwhile it is successful excess and augmented erstwhile procreation is little than demand. Storage is costly and providing retention to code seasonal variations successful star and upwind is prohibitively expensive. To supply affordable energy to consumers, the energy premix indispensable person capable baseload procreation capableness — that is, procreation that is not babelike connected seasons oregon clip of day. Nuclear powerfulness plants are base-load and indispensable beryllium a portion of a decarbonised vigor mix.
Realising this imperative, the units of the Department of Atomic Energy, successful practice with Indian industry, person been moving to harness atomic vigor successful a mode truthful that the implicit proviso concatenation is indigenous. It is lone uranium that has to beryllium imported arsenic India does not person capable uranium. India has developed exertion for fabricating fuel, producing dense water, and manufacturing each the instrumentality that is needed to enactment the operation of Pressurised Heavy Water Reactors (PHWRs). The Nuclear Power Corporation of India Limited has mastered the plan and cognition of PHWRs of assorted ratings, the highest being 700 MW. Three 700 MW units are already working, and the 4th is astir to beryllium completed. Two much are successful an precocious signifier of construction. In 2017, the cardinal authorities sanctioned the operation of 10 700 MW PHWRs and enactment connected these units is progressing.
A regulatory assemblage was established successful the 1980s and has developed the capableness and capableness to modulate atomic powerfulness plants. The Bhabha Atomic Research Centre has developed technologies to reprocess spent atomic substance to retrieve invaluable materials and grip atomic waste. As a effect of these efforts, atomic powerfulness procreation is simply a technically-feasible, affordable and harmless enactment for India.
The SHANTI Bill
These successes person emboldened the cardinal authorities to acceptable a people of 100 GW of atomic installed capableness by mid-century. Both Houses of Parliament person passed The Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India (SHANTI) Bill, 2025. The Bill is an overarching portion of authorities and combines provisions included successful the Atomic Energy Act, 1962, and the Civil Liability for Nuclear Damage Act, 2010. It says that the existing Atomic Energy Regulatory Board “shall beryllium deemed to person been constituted nether this Act”. The Bill ensures that the premier work for safety, information and safeguards lies with the licensee of the facility.
The people acceptable for atomic vigor is ambitious. The Bill passed by Parliament is simply a bold step. India needs ambitious targets and bold steps to go a developed country.
