Renewable Energy

Definition

Renewable energy refers to energy sourced from natural processes that are replenished at a faster rate than they are consumed, such as solar, wind, hydroelectric, and geothermal power. This type of energy is crucial for promoting sustainable urban development because it helps reduce greenhouse gas emissions, minimizes dependence on fossil fuels, and fosters a cleaner environment. By integrating renewable energy into urban planning and infrastructure, cities can enhance their resilience against climate change while supporting economic growth and social equity.
