Water is a renewable resource in the sense that it replenishes itself through rain. However, it is possible to use water in ways that render it a non-renewable resource.Know More
A renewable resource is any natural resource that replaces itself given enough time. The rate of replenishment must be equal to or faster than the rate of usage. As water continuously evaporates from the Earth's surface, it collects in the atmosphere to later come back to the Earth as rain. On the Earth itself surface water replenishes groundwater, and groundwater replaces surface water. With careful management and responsible usage, water is a renewable resource.
There are increasing concerns about water scarcity in many parts of the world, particularly in developing nations or regions of high population density. Only 3 percent of the Earth's water is fresh water, and only one-third of that amount is usable for drinking water. The rest of Earth's fresh water is part of ice caps and glaciers. In many of the world's most populous regions, potable water is a scare commodity because of overuse, mismanagement and pollution.
Hydroelectric power is one important use of water as a renewable resource. Water power is efficient, produces very little waste comparative to other energy sources and the water is reusable.Learn more about Natural Resources
Oil is not a renewable resource because it is a fossil fuel. It takes earth millions of years to produce fossil fuels.Â Full Answer >
Renewable fuels are fuels made from renewable resources. Where fossil fuels are finite, renewable fuels are infinite and examples of renewable fuels include vegetable oil as fuel and methanol made from carbon dioxide.Full Answer >
Non-renewable resources, such as groundwater or fossil fuels, are resources used at a rate higher than the rate at which they can be replenished within a human time frame. Coal, for example, is only created under certain conditions, and it takes millions of years to achieve a form that is useful for energy generation.Full Answer >
The term nonrenewable resource is generally used to refer to the energy-providing resources of oil, coal, natural gas and uranium. Nonrenewable resources are any resources comprised solely, or in part, from elements on the periodic table and that were created through chemical reactions that either required conditions no longer found on Earth or that took millions of years to complete, making them nonrenewable in a practical sense.Full Answer >
