In the context of electric systems, what does renewable energy refer to?

Renewable energy refers to energy that is sourced from naturally replenished resources. This includes energy generated from sources such as solar, wind, hydro, geothermal, and biomass. These resources are sustainable over the long term and can be replenished naturally, making them an environmentally friendly alternative to traditional energy sources. The importance of renewable energy lies in its ability to help reduce greenhouse gas emissions and reliance on fossil fuels, contributing to a cleaner and more sustainable energy future. The key characteristic of renewable energy is its renewability, which distinguishes it from finite resources that can be depleted, such as coal, oil, and natural gas.
