In this world, we have switched to 100% renewable energy. Solar and wind power provide most of the energy needs of households and industry, while excess energy is stored in advanced battery systems or converted into green hydrogen. Fusion energy has become a reality, which means we have an almost unlimited source of clean energy with no hazardous waste.

Cities are being completely transformed - vertical gardens and green roofs preserve air quality and reduce the effect of heat islands. Streets are adapted for pedestrians, cyclists and self-driving electric vehicles that operate on a shared use system, reducing the number of cars and traffic congestion.

Oceans and rivers are clean, with plastics almost completely eliminated or replaced by biodegradable alternatives. Advanced recycling and reuse systems mean that we no longer have a concept of waste - it all goes back into the economy.
