What are limits of renewable resources?
renewable resources in nature, such as plant life (trees etc.) are only renewable as long as the rate of consumption is below the rate of renewing the supply. this goes for water consumption as well. As long as water can be reclaimed above the consumption rate, then it is renewable. Sunlight, as an energy source is renewable, but it is cost affective and also about maintenance of the technology. As long as the technology can be maintained it will be limitless in it’s use. Same goes for wind generation. The universe is limitless however, no matter how we quantize it.
