The key hurdle to climate targets : Electrification

Context: Discussions at the mid-year UN climate talks in Bonn highlighted electrification as a critical component of global decarbonization efforts. Türkiye proposed a global target of achieving at least 35% electrification of final energy consumption by 2035 to accelerate climate action.

Prelims :  

• Electrification refers to replacing direct fossil fuel use with electricity in sectors such as transport, industry, buildings, and agriculture.
• It is considered a key strategy for reducing greenhouse gas emissions.
• The proposal for a 35% electrification target by 2035 was discussed during climate negotiations in Bonn, Germany.
• The target is based on a roadmap prepared by the International Renewable Energy Agency (IRENA).
• The Paris Agreement (2015) aims to limit global temperature rise to well below 2°C and preferably to 1.5°C above pre-industrial levels.

Current Status of Global Electrification

• Electricity currently accounts for only about 21% of global final energy consumption (2025).
• The share has increased only gradually
• Despite rapid technological advances, most global energy demand is still met through direct consumption of fossil fuels.

Growth in Clean Electricity

• The share of non-fossil fuel sources in electricity generation has increased steadily.
• Renewable energy, hydropower, and nuclear power are increasingly contributing to electricity generation.

Why Electrification Matters

• Climate change is primarily driven by greenhouse gas emissions from burning coal, oil, and natural gas.
• Electrification allows fossil-fuel-based activities to be replaced by cleaner energy sources.
• When electricity is generated from renewable or low-carbon sources, overall emissions decline significantly.
• It is considered one of the most effective pathways for achieving long-term decarbonization.

Major Challenges

Hard-to-Electrify Sectors

Several sectors remain difficult to electrify, including:

• Aviation
• Shipping
• Heavy-duty freight transport
• Iron and steel production
• Cement manufacturing
• Ceramics and other high-temperature industrial processes
• Certain residential and commercial heating applications

Dependence on Fossil Fuels

• Around 42% of global electricity generation currently comes from clean sources.
• However, because electricity accounts for only about 21% of final energy use, clean energy effectively meets only a small share of total global energy demand.
• More than 90% of global energy consumption still depends on fossil fuels.

Key Concepts

Final Energy Consumption (FEC):

• Refers to energy directly consumed by end users.
• Excludes energy used during production, conversion, transmission, and distribution processes.

Total Primary Energy Supply (TPES):

• Represents the total amount of energy available for use within an economy before conversion and distribution losses.

Future Outlook

• IRENA estimates that achieving a 35% electrification rate by 2035 is essential for keeping the 1.5°C climate target within reach.
• Achieving this goal would require investments of approximately $1.2 trillion in electricity systems.
• Large-scale expansion of:
  • Renewable energy generation,
  • Electricity grids,
  • Battery storage systems,
  • Electric mobility,
  • Clean industrial technologies,
• will be necessary.

Mains Value Addition

Significance of Electrification

• Accelerates the transition away from fossil fuels.
• Supports achievement of Paris Agreement targets.
• Enhances energy security through greater use of domestic renewable resources.
• Reduces air pollution and associated health impacts.
• Promotes sustainable industrial and transport systems.

Challenges to Achieving Climate Targets

• Slow pace of electrification in key sectors.
• High investment requirements.
• Grid modernization and storage constraints.
• Geopolitical tensions affecting energy markets.
• Continued dependence on coal, oil, and natural gas in many economies.

Electrification is emerging as a cornerstone of global climate strategy. However, achieving meaningful emission reductions will require not only cleaner electricity generation but also a rapid expansion of electricity use across sectors that currently depend heavily on fossil fuels
