From coal to clean
Ali Usman Muhammad
Every morning in India, the rising sun illuminates millions of solar panels quietly converting light into power. Across villages and cities, a silent energy transformation is underway. Developing nations are increasingly turning to sustainable energy not only to combat climate change but also to unlock economic opportunity, as renewable sources reshape how countries grow and function.
For decades, economic growth in developing countries has come at a heavy environmental cost. Rapid industrialization and urbanization have driven rising energy demand, largely met through coal and oil, among the most carbon-intensive fuels. India reflects this dilemma clearly. It is the world’s third-largest carbon dioxide emitter, responsible for roughly 7 percent of global emissions, yet millions of citizens still lack reliable electricity. This coexistence of high emissions and energy poverty shows why the energy transition is not a luxury but a necessity. Sustainable energy offers a path to expand access without worsening the climate crisis, bringing science, innovation, and development together.
India’s energy challenge is one of scale and urgency. As one of the fastest growing economies in the world, the country must meet the rapidly rising electricity demand of its economy driven by population growth, urban expansion, and industrial development. Historically, coal has formed the backbone of India’s power sector, supplying affordable power but at great environmental and public health costs, which include severe air pollution in major cities and persistent respiratory disease for its urban population. At the same time, many rural and peri urban communities continue to experience unreliable or insufficient electricity supply. Balancing economic growth, energy security, and environmental sustainability has therefore become one of India’s defining policy challenges.
Solar energy has emerged as a practical and scalable response to India’s energy challenge. With abundant sunlight, the country has used solar power to diversify its energy mix and reduce reliance on fossil fuels. Over the past decade, India’s solar capacity has grown more than forty times, from around 3 gigawatts in 2014 to nearly 130 gigawatts by 2025, placing it among the world’s largest solar markets. Large-scale solar parks, rooftop installations, and decentralised mini-grids have expanded electricity access, especially in remote regions where grid extension is difficult and costly. Initiatives such as the National Solar Mission have accelerated this shift, making solar energy a central pillar of India’s energy strategy.
India’s progress in solar energy extends beyond just domestic deployment. In 2015, India co founded the International Solar Alliance (ISA) with France, positioning itself as a global leader in advancing solar energy for climate vulnerable regions. Headquartered in Gurugram, the ISA now brings together more than 125 member countries, most of them from the Global South. Its goals are ambitious: mobilising up to one trillion US dollars in solar investment by 2030, supporting the installation of 1,000 gigawatts of solar capacity, and expanding clean energy access to one billion people worldwide. Through policy guidance, technical assistance, and capacity building programmes, the ISA enables developing nations to overcome financing and technological barriers, allowing them to improve from fossil fuel dependent economy development pathways.The science behind renewable energy is simple yet powerful. Solar panels, much like leaves, convert sunlight directly into electricity through the photovoltaic effect, producing power without combustion, smoke, or greenhouse gas emissions. Wind turbines generate electricity by harnessing moving air, while hydropower uses flowing water to spin turbines. Unlike coal-fired plants, which release large amounts of carbon dioxide and cause severe pollution, renewable sources emit little to none during electricity generation. Even when life-cycle emissions are considered, solar and wind remain far cleaner than fossil fuels. According to the Intergovernmental Panel on Climate Change, electricity from solar and wind produces less than 5 percent of the carbon emissions per kilowatt-hour compared to coal-based power. In 2023 alone, renewable energy prevented an estimated 2.5 billion tonnes of carbon dioxide emissions globally.
For developing nations, the benefits of renewable energy extend well beyond emission reduction. Clean energy technologies bring electricity to rural and underserved communities where traditional grid expansion is costly or impractical. In India, decentralised solar systems and mini-grids now power schools, healthcare centres, and small businesses, while training programmes are equipping rural women with green skills and livelihood opportunities. Clean energy also helps address India’s severe air pollution crisis, which causes over 1.6 million premature deaths each year and heavy economic losses. Reducing reliance on coal therefore delivers immediate public health benefits alongside long-term climate mitigation.
The clean energy transition also delivers strong economic benefits. Unlike fossil fuel power plants, which require limited labour once operational, renewable energy systems create jobs across design, manufacturing, installation, and maintenance. Globally, the sector employs over 13 million people, with Asia leading job growth. In India, solar and wind industries have already generated hundreds of thousands of green jobs across technical, managerial, and entrepreneurial roles. Expanding domestic manufacturing of solar panels and batteries can further boost local industries, reduce import dependence, and strengthen the economy. In rural areas, access to clean power supports irrigation, cold storage, and mechanised farming, improving productivity and farmer income.
Despite its promise, the transition to renewable energy faces challenges, including high upfront costs, limited financing, weak grid infrastructure, and the intermittent nature of solar and wind power. However, rapid technological advances are easing these constraints. Battery storage costs have fallen by nearly 90 percent over the past decade, while improvements in smart grids, hybrid systems, and emerging technologies such as green hydrogen are strengthening grid stability and reliability. With supportive policies and sustained investment, these barriers are becoming increasingly manageable.
India’s experience offers valuable lessons for other developing nations. By aligning long term policy vision with falling technology costs, private sector participation, and international cooperation through platforms like the International Solar Alliance, India has demonstrated that rapid clean energy expansion is achievable even in resource constrained settings. More importantly, its transition shows that climate action and economic development do not have to be competing goals. Instead, clean energy can serve as a powerful driver of inclusive growth, energy security, and social progress. Countries across Africa, Asia, and Latin America facing similar challenges can adapt India’s approach to their own local contexts.
Ultimately, the shift to sustainable energy is about more than reducing carbon emissions. It represents a pathway toward healthier populations, resilient economies, and equitable development. Every solar panel installed and every wind turbine constructed contributes to cleaner air, stronger communities, and a more sustainable future. For developing nations, the evidence is clear: investing in clean energy supports affordable electricity, decent work, and climate action simultaneously.
The world now stands at an energy crossroads. Continuing dependence on fossil fuels risks locking in polluted skies, widening energy inequalities gaps, and accelerating climate change impact. Embracing sustainable energy, on the other hand, offers a cleaner and fairer alternative, one in which scientific progress fuels human progress. For countries like India, the energy transition is not just an environmental essential but an economic opportunity. By choosing clean energy today, developing nations can power growth while protecting both people and the planet.
The sun shines equally on all nations. The challenge, and the opportunity, is ensuring that its power does too.
