What characterizes renewable energy sources compared to nonrenewable sources?

Renewable energy sources are characterized by their ability to be naturally replenished over short periods of time. This means that they can continuously provide energy without depleting the resource in the way that nonrenewable sources, like fossil fuels, can. Examples of renewable energy sources include solar, wind, hydro, and geothermal energy. These sources harness natural processes that occur in the environment, such as sunlight or wind, and convert them into usable energy forms without consuming the source itself.

In contrast, nonrenewable energy sources, such as coal, oil, and natural gas, take millions of years to form and, once consumed, are gone for good. This distinction highlights the sustainability of renewable resources, which can help reduce dependence on depleting energy supplies and mitigate environmental impacts, making them a crucial part of efforts to promote sustainable energy practices.
