Renewable energy sources

Definition

Renewable energy sources are natural energy resources that are replenished at a rate equal to or faster than they are consumed, ensuring their sustainability. These sources include solar, wind, hydroelectric, geothermal, and biomass energy, which play a crucial role in reducing dependence on fossil fuels and decreasing greenhouse gas emissions. By integrating these renewable sources into urban infrastructure, cities can create more sustainable environments and enhance their resilience to climate change.
