Surya Nutan: A Stove of Green Energy Transition


From UPSC perspective, the following things are important :

Prelims level: Surya Nutan solar cook-stove

Mains level: India Energy week 2023


Central Idea

  • The formal launch of the Indian Oil Corporation’s patented solar cook-stove at the India Energy Week 2023 (February 6-8, 2023 in Bengaluru as part of the G-20 calendar of events) by the Prime Minister Narendra Modi must be looked at closely from the point of view of India’s national energy story. While Mr. Modi claimed the stove would soon reach three crore households within the next few years, Union Minister for Petroleum and Natural Gas Hardeep Singh Puri called it a catalyst in accelerating adoption of low-carbon options along with biofuels, electric vehicles, and green hydrogen.

Salient features of Surya Nutan solar cook-stove

  • Indoor solar cooking: Surya Nutan is a Stationary, rechargeable, and always kitchen-connected indoor solar cooking.
  • Patented by Indian Oil: This is a patented product designed and developed by Indian Oil R&D Centre, Faridabad.
  • Maximum utilization of solar energy: It offers online cooking mode while charging through the Sun which maximizes the system efficiency and ensures high utilization of energy from Sun.
  • How it will work?: It collects energy from the sun, converts it into heat through a specially designed heating element, stores thermal energy in a scientifically proven thermal battery and reconverts the energy for use in indoor cooking. The energy captured not just covers day time cooking needs of a family of four but also the night meal.
  • Hybrid mode: It works on a Hybrid Mode (i.e. can work on both solar & auxiliary energy source simultaneously) which makes the Surya Nutan a reliable cooking solution for all weather conditions.
  • Minimises heat loss: Insulation design of Surya Nutan minimizes radiative and conductive heat losses.
  • Surya Nutan is available in three different models: The premium model (Breakfast +Lunch+Dinner) of Surya Nutan can cook all the meals for family of four.
  • What will be the cost: Initially, cost of the product is around Rs 12,000 for base model, and Rs. 23,000 for Top Model. However, the cost is expected to reduce substantially with economies of scale. At a price of Rs. 12,000-14,000/- for Top Model, assuming annual consumption of 6-8 LPG cylinders, this product can pay back the buyer in first 1-2 years itself.
  • Inbuilt Safety aspects: All the safety aspects required in any indoor appliances are inbuilt in Surya Nutan.
  • substitute for fossil fuels: The stove, which entails a one-time procurement cost and has zero maintenance, is being touted as a substitute for fossil fuels. It does not have a traditional battery that needs replacement. Also, the solar panel has a 25-year life.
  • Modular system: Surya Nutan is a modular system and can be designed in different sizes as per the requirement.

India’s national energy story

  • In 1950s, the National Physical Laboratory (NPL) fabricated a solar cooker and state-led hydroelectric power but failed to address rural energy consumption.
  • Parallel efforts to improve the traditional stove proved unsuccessful, such as the Hyderabad Engineering Research Laboratories smokeless chulha.
  • 1980s government launched improved chulhas program to reduce fuelwood consumption and benefit women’s health/finances with 50% subsidy incentive. But the program failed due to construction, maintenance, and corruption issues. Women still rely on chulha despite hazards.
  • Cooking is 80% of rural Indian household’s energy use. 668m people in India use biomass for cooking/lighting, despite LPG scheme success. Fuel price inflation and subsidy withdrawal force women to use chulha with hazards.

India Energy Week 2023

  • India’s G20 Presidency: India Energy Week 2023 is being organised during India’s G20 Presidency, under the tagline “Growth, Collaboration, Transition”, from 6-8 February 2023 in Bengaluru.
  • Opportunity for India: It provided a unique opportunity to showcase India as both an engine of global economic growth and a driver for global consumption, supported by a conducive and investment-friendly environment, and a skilled workforce.
  • Opportunity for strategic policy making and knowledge sharing: IEW 2023 was an unprecedented opportunity for regional, international leaders and CEOs to come together for strategic policy making and technical knowledge sharing.

Why In India?

  • India is projected to witness the largest increase in energy demand of any country over the next two decades, as its economy continues to grow and create opportunities for its people to fulfil their potential.
  • India’s share in global energy consumption will rise from 7% to 14% by 2050
  • IEA predicts India will account for 25% of energy demand growth from 2020 to 2040
  • India’s oil and gas demand will triple by 2050
  • Gas consumption to grow threefold by 2030
  • Share of gas in energy mix to rise from 6.3% today to 15% by 2030

Do you know “THE PANCHAMRIT” (The five-nectar-element commitments)?

  1. Indian Will take its non-fossil energy capacity to 500 GW by 2030.
  2. Indian will meet 50 % of its energy requirements from renewable energy by 2030.
  3. India will reduce the total projected carbon emissions by one billion tonnes from now till 2030.
  4. By 2030, India will reduce the carbon intensity of its economy by less than 45 percent.
  5. By the year 2070, India will achieve the target of net zero


  • Surya Nutan has the potential to transform our energy security situation, as India currently imports 50% of its LPG requirements. It also reduces India’s CO2 emissions drastically and keeps our citizens insulated from the vagaries of the high international fossil fuel prices. India’s energy transition will play a pivotal role in global energy markets. India Energy Week comes at a critical time, with the challenges of energy security and environmental sustainability impacting long-term energy transition and paths towards decarbonisation.
