Some examples of limited resources include coal, nuclear, natural gas, metal ores and oil. Limited resources are basically those resources that take a relatively long time to replenish. Unlimited resources or renewable resources, such as water, wind and soil, are the opposite of limited resources.
Limited resources are those things that are important for economic sustainable but are available in limited quantity. While these resources may be replenished, it would take thousands of years before they are renewed.
A good example of limited resources is coal, which is naturally available in certain parts of Earth. Coal is formed as a result of living organisms decomposing and being subjected to extreme temperatures and pressure over thousands of years. Metal ores, natural gas, oil and precious gems like gold and diamond can also be considered limited resources since they are available in small quantities that cannot be replenished.
In recent years, the use of renewable resources has been encouraged as it is easier to replenish such resources. Renewable resources are also eco-friendly, meaning they do not have a negative impact on the environment as compared to limited resources. Renewable resources such as water, wind and solar have been harnessed to produce energy.
