Energy Transitions in India, China, and the US: Paths to a Greener Future

The global energy landscape is undergoing a profound transformation. As climate change accelerates and renewable technologies become increasingly affordable, countries around the world are racing to decarbonize their power sectors. India, China, and the United States-three of the world’s largest energy consumers and carbon emitters-are at different stages of this energy transition, each facing unique challenges and opportunities. Understanding how these nations are navigating their pathways to cleaner energy offers valuable insights into the future of global climate action.

Global energy transition trends

Renewable energy is no longer an alternative-it’s becoming the mainstream. According to the International Renewable Energy Agency (IRENA), the world added a record-breaking 582 gigawatts (GW) of new renewable energy capacity in 2024, marking a 15% increase from the previous year. Solar photovoltaics dominated this growth, contributing nearly 78% of new capacity.

The economics of clean energy have shifted dramatically. In 2024, 91% of newly commissioned utility-scale renewable projects produced electricity at lower cost than fossil fuel alternatives. This cost advantage is driving unprecedented adoption across both developed and developing economies.

Clean electricity sources reached a significant milestone in 2024. Record renewables growth helped push clean power past 40% of global electricity generation, with solar becoming the fastest-growing source of electricity for the 20th consecutive year. Solar generation has doubled over the last three years, reaching over 2,000 TWh globally.

However, progress remains uneven. Non-G7 countries, excluding China, are set to build only one-fifth of global solar and wind projects in the upcoming years. This disparity highlights the need for greater investment in developing nations to ensure an equitable energy transition worldwide.

India’s renewable energy journey

India has emerged as a global clean energy leader with ambitious targets and impressive recent achievements. The country committed at COP26 to reach 500 GW of non-fossil fuel energy capacity by 2030 and achieve net zero emissions by 2070.

Record-breaking capacity additions

India added nearly 35 gigawatts of power capacity in 2024, setting a new record for annual additions. Solar photovoltaic capacity accounted for 71% of all additions, representing the largest annual capacity increase for any technology in the country’s history. By March 2025, India’s total installed renewable energy capacity reached 220.10 GW, with solar capacity standing at 105.65 GW.

The rooftop solar sector has also gained momentum. The PM Surya Ghar: Muft Bijli Yojana scheme, launched in 2024, facilitated 7 lakh rooftop solar installations within ten months, driving a 53% increase in rooftop solar capacity compared to the previous year.

Challenges in the transition

Despite this progress, India faces significant hurdles. To meet the 500 GW target, annual capacity additions need to grow at about 15% year-on-year-essentially doubling the record levels achieved in 2024 by 2030.

Coal remains deeply entrenched in India’s energy mix. The Indian government has redoubled support for coal, with the pipeline of coal plant proposals growing 45% in 2024 to reach 111 GW total capacity. This continued investment in coal infrastructure creates tension with renewable energy goals and raises questions about long-term carbon commitments.

Grid integration and storage remain critical challenges. The intermittent nature of solar and wind power demands robust energy storage infrastructure, but India’s installed energy storage capacity falls far short of the projected requirement of 411 GWh by 2032. Infrastructure limitations, financing gaps, and issues with land acquisition continue to constrain growth.

China’s dominance in renewables

China’s energy transition is a study in contradictions-simultaneously leading the world in renewable deployment while remaining the planet’s largest coal consumer.

Meeting targets ahead of schedule

In 2020, President Xi Jinping set a target of 1,200 GW of combined solar and wind capacity by 2030. China reached this milestone in 2024-nearly six years ahead of schedule. The country’s installed capacity expanded dramatically, with solar growing by 45.2% (277 GW) and wind by 18% (80 GW) in a single year.

China’s wind and solar generation capacity more than doubled in three years, from 635 GW in 2021 to 1,408 GW by the end of 2024. In early 2025, the combined capacity of wind and solar officially overtook coal for the first time in the country’s history.

China attracted $818 billion in clean energy investments in 2024-more than the United States, European Union, and UK combined. This represented two-thirds of the global increase in clean energy investments that year. Clean energy technologies now contribute over 10% of China’s GDP, making them a significant economic driver.

The coal paradox

Despite renewable progress, coal continues to play a central role in China’s energy system. China still consumes over 50% of the world’s coal and continues building new coal-fired power plants. In 2022, China approved six times more new coal capacity than the rest of the world combined.

This reliance stems partly from energy security concerns. Fossil fuels supplied 86% of Greater China’s primary energy in 2024, with coal alone accounting for 54% of electricity supply. The government views coal as essential backup capacity while renewables scale up.

Record-high renewable deployment has helped curb coal power generation and reduced China’s total CO₂ emissions by 1% year-on-year in the first half of 2025. But achieving the country’s 2060 carbon neutrality target will require more aggressive coal phase-out measures in coming years.

The US shift to renewables

The United States has experienced a remarkable energy transformation over the past two decades, with renewable energy finally overtaking coal as a major electricity source.

A historic milestone

In 2024, wind and solar produced a record 17% of US electricity, surpassing coal for the first time in history. Coal’s share dropped to an all-time low of 15%, down from roughly 50% at the turn of the century. The US generated a record 756,621 gigawatt-hours from solar and wind in 2024-enough to power more than 70 million average American homes.

Since coal’s nationwide peak in 2007, wind and solar have surpassed it in 24 states, with half making the switch in just the last six years. In states like Iowa, Kansas, and South Dakota, wind and solar have become the largest sources of electricity generation.

The Inflation Reduction Act’s impact

The Inflation Reduction Act (IRA) of 2022 represents the largest climate investment in US history, directing $369 billion over 10 years into energy and climate programs. The legislation provides tax credits of up to $7,500 for new electric vehicles and up to $4,000 for used EVs, along with substantial incentives for domestic clean energy manufacturing.

Investment in new manufacturing capacity for zero-emissions vehicles, batteries, and critical minerals has jumped more than 100% since the IRA’s passage. Electric vehicle sales have risen from 4.4% to 9.9% of new passenger vehicle sales. Buyers of clean vehicles have collectively saved over $600 million through IRA tax credits, averaging $6,900 per sale.

Natural gas: a transitional challenge

While coal declines, natural gas remains the dominant electricity source in the US, accounting for about 38% of total energy production in 2024. Electricity generated from natural gas has nearly tripled since the early 2000s, slowing the overall transition away from fossil fuels. Addressing this methane-intensive energy source will be crucial for deeper decarbonization.

Looking ahead

The energy transitions in India, China, and the United States demonstrate that clean energy deployment can happen rapidly when economics, policy, and technology align. All three nations have achieved significant milestones, yet each faces distinct challenges-India with financing and infrastructure, China with coal dependence, and the US with natural gas reliance and policy uncertainty.

The path forward requires accelerated renewable deployment, massive investments in grid infrastructure and storage, and credible timelines for phasing out fossil fuels. The decisions made in these three countries over the next decade will largely determine whether global climate targets remain achievable.

What do you think? Can countries successfully balance energy security concerns with aggressive decarbonization timelines? Which nation’s approach to the energy transition do you find most promising for achieving long-term climate goals?
