Energy sources are labelled 'renewable' on the basis that they use resources (e.g. sunlight, wind) that are in one sense unlimited, though at any time and place they may be very limited, even zero. In any case, to harness these renewable sources of energy, plants must be built, which requires the extraction and use of finite mineral resources.Web
