The key hurdle to climate targets: Electrification

Why in the News?

At the Bonn climate talks, Turkey proposed raising the global electrification target to 35% by 2035, ahead of hosting COP31 in Antalya with Australia in November. Electricity meets only a small fraction of the world’s energy needs, and most of that electricity is itself generated from fossil fuels. This exposes a gap between rising clean electricity generation and the much slower pace at which economies actually switch their energy consumption to electricity.

Where does electrification fit among existing global climate goals?

1. Paris Agreement temperature targets: The 2015 Paris Agreement commits the world to limiting the rise in global temperatures within 2 degrees Celsius, preferably 1.5 degrees Celsius, from pre-industrial times.
2. Renewable capacity target: Annual COP meetings have produced the goal of increasing the installed capacity of renewable energy.
3. Net-zero target: COP meetings have also produced the goal of achieving a global net-zero emissions target.
4. Climate finance target: Mobilising climate finance is a further goal that has emerged from COP meetings.
5. Electrification as a new addition: The 35% electrification target, if agreed upon, would be one more addition to this existing set of climate-related global goals, all aimed at reducing the world’s dependence on fossil fuels and speeding up the energy transition.

How is the progress of the energy transition measured?

1. Total Primary Energy Supply (TPES): A measure of all energy available for use in an economy, including energy consumed in producing, transforming and transporting energy itself.
2. Final Energy Consumption (FEC): A measure of energy ultimately used by end-consumers. It excludes energy burnt to produce electricity, energy used in refining petroleum, diesel burnt in transporting fuel, and transmission and distribution losses.
3. Structural difference between fossil fuels and renewables: Fossil fuels are direct sources of energy and only require to be burnt to produce energy, whereas renewable sources such as solar, wind, nuclear or hydropower have to be converted into electricity before they can be put to use.
4. Why electrification rate is the relevant metric: Because renewable sources require conversion into electricity before use, every final use of energy would have to be electrified for a complete transition away from fossil fuels to be possible.

Why does electrification remain limited despite rising electricity demand?

1. Slow movement in FEC share: Electricity’s share in FEC rose only from 17.7% in 2015 to 21% in 2025, a modest increase over a decade.
   1. Global electricity share in FEC: Electricity accounted for only 21% of total final energy consumption (TFEC) in 2025, according to the IEA.
   2. India’s electricity share in FEC: The corresponding figure for India is about 23%, according to government data.
2. Rising generation volumes: Global electricity generation increased from about 24 terawatt-hours (TWh) in 2015 to over 32 TWh in 2025, a rise of nearly 33%.
3. Generation growth has outpaced consumption-side electrification: Electricity output rose by a third over the decade while its share of final consumption rose by only about 3 percentage points.
4. Hard-to-electrify sectors persist: Shipping, aviation, heavy-duty and long-haul trucks, high-temperature industrial processes in iron, steel, cement and ceramics, and many residential needs like heating remain largely unelectrified and cannot run on renewables.

Which sectors remain difficult to electrify?

1. Aviation: Long-distance air travel lacks commercially viable large-scale electric alternatives.
2. Shipping: Heavy maritime transport depends on high-energy-density fuels.
3. Heavy Industry: Steel, cement and chemicals require high-temperature industrial processes.
4. Long-Haul Freight: Heavy trucks face battery and charging limitations.
5. Energy-Intensive Manufacturing: Several production processes remain dependent on fossil fuels.

Why does renewable energy success not automatically translate into climate success?

1. Steady rise in clean generation share: The share of non-fossil sources (renewables, hydro and nuclear) in electricity generation rose from 33.6% in 2015 to 42.6% in 2025, according to the IEA.
2. Electricity itself is still the majority fossil: In 2025, only about 42% of all electricity generated worldwide came from non-fossil sources, meaning most electricity generated is still fossil-based.
3. Compounding effect on total energy use: Only 21% of total final energy consumption is met through electricity, and only about 42% of that electricity is clean.
4. The reality-check figure: This means just over 8% of total energy consumed in the world is currently clean.
5. Three decades of policy effort, limited consumption-side result: Nearly three decades of favourable policies, financial incentives and technology innovation to promote cleaner fuels have left more than 90% of current global energy use still dependent on fossil fuels.

How ambitious is the proposed 35% electrification target?

1. IRENA’s threshold for 1.5°C: The International Renewable Energy Agency states that a 35% electrification rate by 2035 is the minimum needed to keep any realistic hope of staying on the 1.5-degrees Celsius pathway.
2. Investment requirement: Achieving that level of electrification requires about $1.2 trillion to be pumped into electricity systems every year.
3. Accompanying requirements: Rapid expansion in renewables and battery storage systems must also happen alongside this investment.
4. Scale of the gap from current trajectory: The IEA projects electricity’s share of global FEC will rise to only about 24% by 2030, against a target of 35% by 2035, even as non-fossil sources (renewables plus hydro and nuclear) are projected to supply nearly half of global electricity by 2030.

What risks could derail even this limited trajectory?

1. Geopolitical uncertainty: It is unclear how wars and geopolitical tensions will affect the pace of energy transition.
2. Two opposing pressures: Greater uncertainty in fossil fuel supplies and rising oil prices may push some countries toward renewables, while the economic fallout of conflicts may squeeze budgets available for new technologies and infrastructure.
3. Risk of reverting to convenient fuels: Countries may be tempted to use whatever energy source is easily available, regardless of its climate impact.

What do international targets indicate about the future direction of climate policy?

1. COP28 Consensus: Countries agreed to accelerate the global energy transition.
2. IRENA Roadmap: The agency proposes raising electrification to 35% by 2035.
3. Net-Zero Pathways: Most credible decarbonisation scenarios require major electrification gains.
4. Renewables-Electrification Link: Renewable expansion and electrification must progress together.
5. Long-Term Transition: Climate targets increasingly depend on transforming energy consumption patterns, not merely energy production.

Conclusion

Clean electricity generation has scaled steadily, but the constraint on climate targets has shifted to how much of total energy consumption is electrified, not how clean the electricity supply is. Only about 8% of global energy consumption is currently clean, and electricity’s FEC share is projected to reach just 24% by 2030 against a 35% by 2035 target. Hence, climate progress will remain limited unless transport, industry and buildings convert their direct fossil-fuel use to electricity at a much faster pace.
