<\/a>Why AI Needs So Much Energy?<\/b><\/span><\/h2>\n
    \n
  1. High Computational Requirements<\/b>: AI models like <\/span>GPT-4<\/b> require massive computing during training and inference stages. Each training cycle can emit as much CO\u2082 as five cars running across their lifecycle. <\/span>Example:<\/b> MIT Technology Review estimates AI model lifecycle emissions rival some small nations’ per capita CO\u2082.<\/span><\/li>\n
  2. Continuous Power Use Post-Deployment<\/b>: Once deployed, AI models operate across global servers 24\/7. Tools like ChatGPT or Midjourney continuously consume energy to serve millions of users daily<\/span>. Example:<\/b> Midjourney and DALL\u00b7E require high-resolution image synthesis, stressing data centres 24×7.<\/span><\/li>\n
  3. Data Storage and Management<\/b>: AI relies on gigantic datasets stored in high-performance storage systems. These systems demand constant cooling and uninterrupted energy supply. Data centres need continuous cooling, consuming <\/span>additional 40-50%<\/b> of the total energy.<\/span><\/li>\n
  4. Energy-Intensive GPUs<\/b>: AI depends on <\/span>power-hungry GPUs (Graphic Processing Units)<\/b>. <\/span>Example:<\/b> OpenAI\u2019s CEO tweeted <\/span>\u201cour GPUs are melting,\u201d<\/b> illustrating thermal and energy inefficiencies.<\/span><\/li>\n
  5. Edge AI and Real-time Analytics<\/b>: As AI integrates with IoT and real-time applications, more decentralized processing (Edge AI) will further increase total power requirements. AI services demand <\/span>always-on global infrastructure<\/b>. <\/span>Example:<\/b> Amazon, Microsoft, and Google run <\/span>redundant global data hubs<\/b> powered by fossil-heavy grids.<\/span><\/li>\n<\/ol>\n

    <\/a>What is an SMR and How It Can Support AI\u2019s Energy Needs?<\/b><\/span><\/h2>\n

    Small Modular Reactors (SMRs)<\/b> are compact, factory-fabricated nuclear reactors that generate <\/span>50-300 MW<\/b> of electricity. Their design enables scalability, faster deployment, and co-location with energy-intensive infrastructure like AI data centres.<\/span><\/p>\n

      \n
    1. Economic Competitiveness:<\/b> As per NITI Aayog, SMR projected to lower electricity costs from \u20b910.3 to \u20b95\/kWh in India post-deployment.<\/span><\/li>\n
    2. 24×7 Baseload Energy<\/b>: Unlike solar or wind, SMRs provide <\/span>continuous power<\/b>, ideal for AI uptime needs. <\/span>Example: <\/b>Google signed an agreement to power AI systems using nuclear energy (2023).<\/span><\/li>\n
    3. Low Carbon Footprint<\/b>: SMRs offer <\/span>zero direct CO\u2082 emissions<\/b> during operation, supporting net-zero goals.<\/span><\/li>\n

    5. Space Efficient<\/b>: Require smaller land footprint compared to solar or wind farms per MW.<\/span><\/li>\n
    6. Faster Deployment<\/b>: SMRs can be operational in <\/span>3\u20135 years<\/b>, compared to 10+ years for large nuclear plants.<\/span><\/li>\n
    7. Enhanced Safety<\/b>: Passive safety systems reduce meltdown risks. <\/span>Example: Rolls Royce SMRs use natural convection for cooling.<\/b><\/li>\n
    8. On-site Integration<\/b>: Co-location with AI clusters reduces <\/span>transmission losses<\/b>. <\/span>Example: Microsoft to use SMR power at former Three Mile Island site.<\/b><\/li>\n
    9. Hydrogen and Heat Co-production<\/b>: SMRs can generate <\/span>industrial heat and hydrogen<\/b>, powering AI + green industries.<\/span><\/li>\n
    10. Water Neutral Design: <\/b>Newer SMRs require <\/span>less or recycled water<\/b> for cooling\u2014key in arid zones.<\/span><\/li>\n
    11. Economic Viability<\/b>: Projected costs in India to fall to \u20b95\/kWh post-<\/span>operationalization (as per NITI Aayog projections).<\/b><\/li>\n<\/ol>\n

      <\/b><\/a>What is the Significance of SMRs Across Different Sectors?<\/b><\/span><\/h2>\n
