Energy Transition: Meaning, Pillars, Pathways and Why It Matters for Corporate ESG

What Is Energy Transition: Definition and Why It Matters

Energy transition can therefore be described as the process through which there will be a fundamental change in the nature of the global energy system as a result of the move from traditional energies, including coal, oil, and natural gas, to more sustainable forms of energy that are low in carbon emission and energy use efficient. However, energy transition is more than a simple process of changing from traditional energy sources to new ones.

The components of energy transition consist of renewable energy generation from solar, wind, and hydroelectric power plants; increase in energy efficiency; vehicle electrification; manufacturing of green hydrogen; energy storage; and upgrades in the energy grid infrastructure. This change will have major impacts on industry competitiveness, industry investment opportunities, and the regulatory framework.

The energy transition is already here and happening at an increasing pace. Clean energy had been receiving more than two-thirds of global energy investment by 2025 (according to IEA, 2025), which includes investment worth USD 450 billion into solar – more money invested into a single energy technology than any other at all times in human history.

Why Energy Transition Matters for Businesses and Corporate ESG

Renewable Energy Transition leads to tangible impacts on companies' financials, regulation, and reputation.

On the financial side:

Today, renewables represent the most cost-efficient source of new electricity production in many regions (IRENA, 2025). Companies that consume renewable energy and enhance energy efficiency cut their operational costs significantly. Others risk being exposed to carbon prices, energy price fluctuation, and stranded assets due to depreciation of fossil fuel-based energy production.

On the regulatory side:

India's CCTS obliges organizations in nine energy-intensive sectors to cut their GHG emission intensity. SEBI's BRSR Core demands reporting of energy consumption, energy intensity, and share of renewables. The EU CBAM introduces a carbon border tax on steel, cement, and aluminum produced in countries outside the EU. Both regulations explicitly depend on a company's progress in renewable energy transition.

Regarding ESG: In fact, the “E” in ESG is closely associated with energy transition processes. Scope 1 & 2 carbon emissions, energy intensity, and renewable energy procurement – these are just some examples of metrics included in the list of BRSR Core parameters.

The Key Pillars of Energy Transition

Major Pathways and Technologies Driving the Energy Transition

Renewable energy shift is moving along six interrelated technology paths:

• Solar photovoltaic systems are the biggest element in world energy investments, accounting for USD 450 billion in 2025 (IEA, 2025). Both utility and roof-top solar power have become the least expensive source of new electricity, including India, where the solar power installation in 2025 was 34.98 gigawatts.

• The second important renewable technology is wind power, both on- and off-shore. India is ranked as the fourth country in terms of wind power installed capacity (IRENA, 2025), and offshore wind energy development is gaining momentum.

• Green hydrogen generated through electrolysis with the help of renewable electricity is the remedy for decarbonizing industries such as steel and fertilizer production, aviation, and maritime transport. India's National Green Hydrogen Mission aims at annual green hydrogen production of 5 million metric tons by 2030.

• The battery energy storage system ensures that renewable energy production is regulated by managing the issue of intermittent production, hence ensuring availability of energy 24 hours round and eliminating diesel generators in industries and data centers.

• Efficient technology in energy (such as variable speed drives, heat pumps, LED lighting, and building management systems) cuts down energy requirements through all sectors and offers cost reductions.

• Electrification of transport and heat changes fossil fuel usage into electrical energy requirements. 

Real-World Examples of Corporate Energy Transition

How Companies Can Build an Energy Transition Plan: Step-by-Step Framework

Step 1:

Conduct an energy audit and baseline assessment. Measure current energy consumption by source, calculate Scope 1 and 2 GHG emissions, and map energy intensity by production unit. Identify the largest energy-consuming facilities and processes.

Step 2:

Set science-based targets (SBTs). Align GHG reduction targets with a 1.5°C pathway using the SBTi. Separate short-term operational targets (2025-2030) from long-term net zero milestones.

Step 3:

Map renewable energy procurement options. Evaluate open access solar, group captive renewable projects, Power Purchase Agreements (PPAs), and Renewable Energy Certificates (RECs) based on geography, grid access, and BRSR reporting obligations.

Step 4:

Develop a phased energy transition plan. Prioritise high-impact, lower-cost actions first: energy efficiency retrofits, fuel switching, and renewable electricity procurement. Sequence longer-horizon investments: green hydrogen, deep electrification, and carbon capture.

Step 5:

Align with ESG and regulatory frameworks. Map your energy transition plan to BRSR Core energy intensity indicators, CCTS GEI targets, TCFD Strategy disclosures, and IFRS S2 requirements for a coherent, single evidence base.

Step 6:

Monitor, verify, and disclose. Set annual milestones, appoint an accredited verifier, and disclose progress through BRSR, CDP, and sustainability reports.

Common Mistakes Companies Make in Their Energy Transition Strategy

Such mistakes happen quite regularly within corporate energy transition programs:

• Not making changes to the structure – buying RECs makes for fewer emissions on paper, but doesn’t bring any change in the structure itself, nor satisfies third-party verification of BRSR Core.

• Basing goals on anything but science – without the SBTi verification, the company risks accusations of greenwashing by investors, banks, and regulators.

• Ignoring Scope 3 – focusing on Scope 1 and 2, ignoring supply chains and use of products, when Scope 3 emissions form most of a company’s carbon footprint.

• Detaching energy transition from capital planning – the process involves investment, treating it as a reporting matter, which doesn’t involve funding for any of the projects, means failing at delivery.

• Missing connections within Indian regulations – the relationship between CCTS, BRSR Core, green bonds, and India’s national target of 500 GW should be considered, or all the efforts will be futile.

How Oren Helps Companies Plan and Execute Their Energy Transition

Oren supports Indian and global companies at every stage of their energy transition journey.

Oren's energy transition advisory covers: energy baseline assessment and Scope 1, 2, and 3 GHG measurement; science-based target development and SBTi alignment; renewable energy procurement strategy (open access, PPAs, captive solar, RECs); energy transition plan development aligned with BRSR Core, TCFD, and IFRS S2; CCTS compliance planning; and green bond or sustainability-linked loan readiness for financing the transition.

For Indian listed companies, Oren's integrated approach ensures that the energy transition plan simultaneously serves as a regulatory compliance tool (BRSR, CCTS), a capital markets instrument (green bonds, SLL), and a genuine operational roadmap, not merely a disclosure exercise.
