Renewable resources refer to natural sources that can be replenished or regenerated over time, either through human intervention or by natural processes. These types of resources are considered sustainable and environmentally friendly because they do not deplete finite resources or contribute significantly to pollution. Examples of renewable resources include solar energy, wind power, hydroelectricity, geothermal heat, biomass (such as wood), and some forms of waste. The use of these resources helps reduce our dependence on non-renewable sources such as fossil fuels, which are finite and contribute to climate change when burned.
