What phrase describes resources that naturally replenish themselves over time?

The phrase that describes resources that naturally replenish themselves over time is "renewable resources." These are resources such as solar energy, wind energy, water, and biomass that can be regenerated naturally at a rate that allows them to be sustained over time. For instance, trees can be replanted, and solar panels will continue to provide energy as long as the sun shines, demonstrating the replenishing nature of these resources.

In contrast, non-renewable resources are those that do not replenish within a human timescale, such as fossil fuels and minerals. Conventional resources may refer to commonly relied-upon sources but do not inherently indicate anything about their renewability. Exhaustible resources are often confused with renewable ones; however, exhaustible resources are limited in quantity and can eventually be depleted, whereas renewable resources can be reused perpetually if managed sustainably.
