One vision I have for 2040 is a world where clean energy has fully replaced fossil fuels. In this future, renewable energy sources like solar, wind, and fusion power provide abundant, affordable electricity to everyone. Cities are designed to be energy-efficient, with smart grids that optimize power usage and storage. Electric transportation dominates—cars, buses, and even airplanes run on sustainable energy, eliminating carbon emissions. Climate change is no longer a looming disaster because global temperatures have stabilized, and ecosystems are recovering from centuries of damage.In this world, energy is no longer a source of conflict but a shared resource that supports innovation, economic equality, and a cleaner planet.
