India aims to increase its nuclear power capacity to 100 GW by 2047, the 100th anniversary of its independence, up from current levels of around 8.8 GW. Driven by the Nuclear Energy Mission and the SHANTI Act of 2025, this plan seeks to achieve net-zero emissions by 2070. This expansion relies on a mix of indigenous 700 MW reactors, new Small Modular Reactors (SMRs), and increased private sector participation.

India aims to increase its nuclear power capacity to 100 GW by 2047, the 100th anniversary of its independence, up from current levels of around 8.8 GW. Driven by the Nuclear Energy Mission and the SHANTI Act of 2025, this plan seeks to achieve net-zero emissions by 2070. This expansion relies on a mix of indigenous 700 MW reactors, new Small Modular Reactors (SMRs), and increased private sector participation. 

Key aspects of India's 100 GW nuclear goal:
Targeted Timeline:-
 The 100 GW capacity is expected to be achieved by 2047.
Medium-Term Growth: -
Capacity is projected to reach approximately 22 GW by the early 2030s.
Strategy:-
 The plan includes 700 MWe indigenous Pressurised Heavy Water Reactors (PHWRs), large imported reactors, and Small Modular Reactors (SMRs) like the 200 MWe Bharat Small Modular Reactor (BSMR-200).
Legislative Support: -
The SHANTI Act of 2025 allows private sector participation in building and operating nuclear plants, replacing the outdated Atomic Energy Act of 1962.
Financing: -
Reaching this target requires about ₹15 lakh crore ($180 billion) in investment, according to a Drishti IAS report.
SMR Development:-
 Over ₹20,000 crore has been allocated to develop SMRs, aiming for at least five indigenously designed SMRs to be operational by 2033. 
India's Nuclear Century: Chasing the 100-GW power target by 2047
 Achieving the 100 GW policy target will require: * Timely execution * Scaling advanced designs and fuel security * 

Kudankulam Nuclear Power Plant (KKNPP) (Tamil Nadu): -
The largest station, featuring 2 x 1,000 MWe Pressurized Water Reactors (PWR) in operation, with expansion underway.

Tarapur Atomic Power Station (TAPS) (Maharashtra): -
India's oldest atomic power station (commissioned 1969), consisting of BWRs and PHWRs.

Rajasthan Atomic Power Station (RAPS) (Rawatbhata, Rajasthan): -
Operates multiple pressurized heavy water reactors (PHWRs).

Kakrapar Atomic Power Station (KAPS) (Gujarat): -
Operates indigenous 220 MWe and new 700 MWe PHWRs.

Kaiga Generating Station (KGS) (Karnataka): -
Operates four units of 220 MWe each.
Madras Atomic Power Station (MAPS) 

(Kalpakkam, Tamil Nadu):-
 First fully indigenously  constructed nuclear power station.Narora Atomic Power Station (NAPS) (Uttar Pradesh): -
Features two 220 MWe PHWR units. Atomic Energy Regulatory Board +7
Key Facts & Ongoing Construction
Total Capacity: -
8,880 MWe.

Solar Generation in Night hrs

How to get get Solar generations in Night        While standard solar panels cannot generate electricity at night,     New technologies are being developed to address this limitation.      These advancements focus on harnessing the earth's heat or using infrared radiation emitted by the Earth to generate power, potentially creating 24-hour renewable energy sources.  Key Concepts and Technologies :- 1) Anti-Solar Panels (Thermo-radiative Cells):- How they work:-    These panels, also known as thermoradiative cells, work in reverse of traditional solar panels. Instead of absorbing sunlight, they emit infrared radiation into space, which is then converted into electricity.    Nighttime energy:-     They can generate electricity from the difference in temperature between the panel and the surrounding environment, essentially converting the heat escaping into space back into usable power.  Potential:-  ...

Hydrogen at home — It's the end of solar and wind power

  Hydrogen at home — It's the end of solar and wind power         Statement "1000 pounds" per day of hydrogen at home — It's the end of solar and wind power in the world" is not accurate.     While hydrogen can be produced from renewable energy sources like solar and wind power, it's not a replacement for those sources themselves. Hydrogen production via electrolysis, using renewable electricity, is a promising avenue for decarbonization, but it doesn't negate the need for solar and wind power as direct energy sources.  Cause behind its is as under. Hydrogen as an Energy Carrier:-     Hydrogen is an energy carrier, meaning it stores energy produced elsewhere (like from solar or wind) and can be used to power fuel cells or for other applications.  Electrolysis:-     A key method of producing "green" hydrogen involves using electricity from renewable sources (like solar and wind) to split water into hydrogen and oxygen throu...

State-wise carbon emissions in India show a concentration in western and southern states, with byd as major emitters, particularly from the manufacturing and energy sectors. The highest total CO2 emissions have been linked to states like Maharashtra, Andhra Pradesh, Uttar Pradesh, Gujarat, Tamil Nadu, and West Bengal, though the specific ranking can vary depending on the data year and the specific pollutants included.
