Match the suitable renewable and non-renewable resources. Sources A B C Renewable Coal Wind Petroleum Non-renewable Hydrogen Natural gas Solar energy

Renewable sources: Wind, solar energy, hydrogen. A renewable resource, also known as a flow source, is a natural resource which will replenish to replace the portion depleted by usage and consumption, either through natural reproduction or other recurring processes in a finite amount of time in a human time scale. Non-renewable: Coal, petroleum, natural gas. A non-renewable resource (also called finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. An example is carbon-based fossil fuels.
