EVERYDAY SCIENCE

Detailed explanation-1: -Renewable resources are those resources that continue to exist despite being consumed or can replenish themselves over a period of time even as they are used. They include the sun, wind, water, geothermal, and biomass.

Detailed explanation-2: -Nonrenewable resources are finite and are therefore unsustainable. We are currently depleting nonrenewable resources (coal, oil, and natural gas) at an alarming rate. As of 2015, at this rate, we will run out of coal by 2130, natural gas by 2069, and oil by 2067.

Detailed explanation-3: -Sustainable development is the type of development that satisfies the current needs of the society without interfering with “the ability of the future generations to meet their own needs”. On the contrary, unsustainable development does not consider the future generations, or their needs.

Detailed explanation-4: -A common misconception is that renewable energy sources will never run out. And while it is true that renewable resources naturally replenish themselves over time, they can only remain in infinite supply if we use the resources sustainably.
