Opening my window first thing in the morning to take a fresh breath of clean air. This was despite living in eternally growing city of London. The air was crisp and without any pollutant smells. It was like being in a dense forest - the scent of trees and nature. Looking across the city I saw the glow of the rooftops - solar panels. Yes even in cloudy London everyone used solar power. This was because the tech had become so efficient that it was now possible to generate enough electricity for the average flat. Looking around I also spotted the buildings that instead chose to opt for green roofs. Vegetation and plants being used as a natural insulator but also to reduce the ovrrall temperature of the city during the hot summer months. Because the summers were getting hotter than ever each year. Thankfully this idea cooled the city down enough for it to be tolerable.
