For the first time, renewables have toppled coal as the world’s leading source of electricity, in keeping with International Energy Agency projections for this historic shift. But progress is uneven. The shift away from fossil fuels has slowed in the United States and the European Union – but accelerated sharply in developing nations.

China attracts headlines for the sheer scale of its shift. But many smaller nations are now taking up clean energy, electric vehicles and battery storage at remarkable speed, driven by governments, businesses and individuals. Importantly, these moves often aren’t about climate change. Reasons range from cutting dependence on expensive fossil fuels and international market volatility to reducing reliance on unreliable power grids to finding ways to boost livelihoods.

Pakistan’s enormous solar boom is partly a response to spiking power prices and grid unreliability. Meanwhile Pacific nations see clean energy as a way to slash the crippling cost of importing diesel and expand electricity access.

My research has given me insight into the paths four countries in South Asia have taken to seize the benefits of clean technology, each shaped by unique pressures and opportunities. All are moving rapidly, blending necessity with ambition. Their stories show the clean energy path isn’t one-size-fits-all.

Bhutan: from hydropower giant to diversified energy

The landlocked Himalayan kingdom of Bhutan has long relied on hydroelectricity. But the country faces a persistent challenge: seasonal variability. Most of Bhutan’s plants are run-of-the-river, meaning they don’t have large dams. As a result, power generation drops sharply during dry winter months when river flows are low, particularly between January and April.

At the same time, rapid industrialisation has driven up demand for power, outstripping winter capacity. Climate change is expected to worsen this variability. During these months, Bhutan shifts from its role as clean-energy exporter to an importer, buying electricity from India. But imports aren’t a long-term solution.

To secure reliable supply year-round, Bhutan’s government is diversifying energy sources. To that end, up to 300 megawatts of solar is expected to be installed, potentially as soon as next year. Bhutan’s first utility-scale solar farm is under construction. Over time, Bhutan will blend hydro with solar, wind and biomass to create a more balanced clean energy mix….
