Renewable energy systems

Definition

Renewable energy systems are technologies and processes that generate energy from natural resources that are replenished at a faster rate than they are consumed. These systems utilize sources like solar, wind, hydro, and biomass, offering a sustainable alternative to fossil fuels. By integrating these systems into urban environments, cities can significantly reduce their carbon footprint, improve energy efficiency, and foster a cleaner, more resilient future.
