## TL;DR
Renewable Energy: Renewable energy comes from naturally replenished sources such as sunlight, wind, moving water, geothermal heat, and biomass.

## Core Explanation
Renewable power can reduce fossil-fuel dependence and greenhouse-gas emissions, but deployment quality depends on grid integration, storage, siting, transmission, supply chains, and policy. Public claims should distinguish electricity generation from total energy use.
