CLIMATE change is no longer merely an environmental concern; it is a growing threat to public health and sustainable development in Pakistan. Rising temperatures, heatwaves, floods and deteriorating air quality are affecting communities, livelihoods and healthcare services. A key response is the transition towards green energy.
Renewable sources, particularly solar and wind power, offer benefits beyond electricity generation. They can reduce dependence on fossil fuels, lower greenhouse gas emissions and help limit air pollution. Green energy is not only an energy priority but an investment in climate resilience and public health.
Pakistan is vulnerable to climate hazards. Extreme heat increases the risk of heatstroke, dehydration, kidney injury and cardiovascular complications. Floods can contaminate drinking water, damage sanitation systems, disrupt healthcare and increase diarrheal and vector-borne diseases. Meanwhile, polluted air contributes to respiratory and cardiovascular illness, placing further pressure on the health system.
The energy sector is part of this challenge. Burning coal, oil and gas releases greenhouse gases that drive global warming, alongside pollutants that harm human health. Shifting towards renewable electricity, cleaner public transport and clean cooking can help reduce these risks. Solar and wind power produce little or no direct air pollution during operation, although their benefits depend on responsible planning, reliable grids and energy storage.
Pakistan has potential to expand solar energy. The use of rooftop solar demonstrates public interest in alternative electricity sources. However, a national approach is needed to ensure affordable access, battery storage and reliable integration with the electricity grid. The transition must benefit low-income households and underserved communities, not only those able to invest in private systems.
The healthcare sector should be a priority. Hospitals, basic health units, laboratories and vaccination Centres need reliable electricity. Solar-powered facilities, supported by battery storage and backup systems, can improve energy security in remote areas. Uninterrupted power is vital for vaccine cold chains, diagnostic equipment, emergency care and patient treatment. Renewable energy can reduce facilities’ environmental footprints while strengthening resilience during power disruptions and extreme weather.
Pakistan must also integrate climate risks into health planning. Heat-health action plans, climate-sensitive disease surveillance, flood preparedness, resilient health facilities and public awareness should be strengthened. Health, energy, environment and disaster management institutions need to work together, supported by research, sustainable financing and international cooperation.
The relationship is clear: cleaner energy can reduce emissions and harmful air pollution; climate action can lower future health risks; and resilient energy systems can help keep healthcare services running. Pakistan should measure its green transition not only in megawatts generated, but also in cleaner air, healthier communities and lives protected. Green energy is more than an alternative source of electricity. It is an investment in climate security, disease prevention and a healthier, more sustainable Pakistan.
