Why in the News?

Recent international climate discussions, including follow-up deliberations after Bonn Climate Conference, highlighted electrification as a key strategy for achieving global climate goals.

News in Brief

• International agencies view electrification as the backbone of the global energy transition and a key instrument for reducing greenhouse gas emissions.
• Policy makers and energy agencies are considering increasing the share of electricity in final energy consumption as part of efforts to accelerate the global energy transition and reduce dependence on fossil fuels.
• The proposal aims to support global commitments under the Paris Agreement and net-zero pathways.

Significance of Electrification

• Reduces dependence on fossil fuels
  • Most green house gas emissions originate from the combustion of coal, oil and natural gas.
  • Electrification enables cleaner alternatives when electricity is generated from renewable sources.
• Improves energy efficiency
• Facilitates renewable energy integration
  • Solar, wind, hydro and nuclear energy generate electricity.
• Supports net-zero commitments

Current Global Scenario

Electricity’s share in final energy consumption

• Electricity constitutes  only about one-fifth to one-fourth of global final energy consumption.
• Despite growth in electricity generation, many sectors remain heavily dependent on direct fossil-fuel use.

Progress in Clean Energy

• The share of non-fossil fuel sources in electricity generation has steadily increased due to
  • Solar energy expansion
  • Wind power deployment
  • Hydropower
  • Nuclear energy
• However, fossil fuels still dominate a significant portion of global electricity production.

Proposed Global Electrification Target

• Target – Increase electricity’s share in final energy consumption to approximately 35% by 2035.
• Significance
  • Accelerates decarbonization
  • Supports the 1.5 degree Celsius climate goal
  • Enhances energy security
  • Reduces long-term fossil fuel dependence.

Opportunities for India

• Accelerate growth in renewable energy.
• Expansion of electricity mobility
• Promoting Green hydrogen initiatives
• Reduce fossil fuel imports.

Challenges to Electrification

• Certain sectors are difficult to electrify.
  • Aviation, Shipping, Heavy  trucking, Steel manufacturing, Cement production, High-temperature industrial processes.
• Large-scale electrification requires, transmission networks, distribution systems, smart grids, and grid modernization.
• Intermittent renewable sources need battery storage, pumped hydro storage, and other balancing mechanisms.
• The transition demands substantial investments in,
  • Clean energy infrastructure
  • EV charging networks
  • Industrial electrification
  • Transmission systems.
• Supply chain and geopolitical risks associated with the availability of critical minerals (lithium, cobalt, nickel and rare earth elements) can influence the pace of electrification.

Way Forward

• Scale up Renewable Energy
  • Accelerate solar, wind, nuclear and hydro capacity additions.
• Modernize power grids
  • Develop resilient and smart electricity networks.
• Promote Electricity mobility
  • Expand EV adoption through incentives and charging infrastructure.
• Electrify industry and buildings
  • Encourage clean industrial technologies and energy-efficient appliances.
• Increase Investments
  • Mobilise public and private capital for energy transition projects.
