Geothermal heat, green charcoal and rooftop solar emerge as practical alternatives amid global energy shocks.

From Sun to Subsoil: How Nations Are Cutting Dependence on Fossil Fuels.

As oil and gas prices surge due to geopolitical tensions, countries across continents are accelerating their shift away from fossil fuels. In France, residents near Paris have begun heating homes with geothermal energy, tapping natural heat from beneath the ground. The switch from gas is already delivering up to 20% savings on heating bills, while shielding consumers from volatile fuel markets, according to utility major ENGIE. In Chad, plant-waste briquettes—dubbed “green coal”—are replacing traditional charcoal. Made from agricultural residues, the cleaner-burning fuel lasts longer, reduces deforestation, and cuts indoor pollution, though limited production constrains wider access. Meanwhile, Pakistan is witnessing one of the world’s fastest consumer-led solar transitions. Rooftop panels now blanket cities like Islamabad and Lahore, driven by soaring fuel costs, cheap imports, and chronic power shortages. Together, these innovations show how local, renewable solutions can ease energy costs while reducing reliance on oil and gas.
