Which source of energy is not renewable
Renewable resources are resources that are replenished naturally in the course of time. The use of these resources corresponds with the principles of sustainability, because the rate at which we are consuming them does not affect their availability in the long term. Examples include solar energy, wind, and. . In contrast, non-renewable resources are those available in limited quantities or those that take so long to regenerate that we are consuming. . Every day, the choices we make—what we buy, how we travel, how much energy we consume—directly consume natural resources. In fact, the average person in developed countries. [pdf]
