Renewable and Nonrenewable Energy Resources | AP Environmental Science | Khan Academy

Today, let's talk about energy resources. You've probably already done something today that used energy resources, even beginning from the moment you woke up. For me, the beginning of my day always starts with making tea. I use energy in every step of this process. My car uses oil when I drive to the grocery store to get the tea. My stove uses natural gas when I boil the water, and my water heater uses coal-sourced electricity when I wash my mug in hot water.

Afterwards, we use energy constantly in our daily lives. Since the first law of thermodynamics states that energy cannot be created nor destroyed, where does it all come from, and will we have enough? When we talk about energy resources, we could split it up into two groups: renewable energy and non-renewable energy. I can always remember what renewable resources are because the prefix "re" means again, and the root "new" refers to the origin of the energy source.

So, renewable energy sources are the sources that we can use again and again and are quickly restored by natural processes. Renewable fuel sources include sunlight, wind, moving water, biomass from fast-growing plants, and geothermal heat from the earth. The lifespan of renewable resources looks like a circle. We can use them, and then we can use them again without worrying about them running out.

Non-renewable energy sources, on the other hand, are sources that exist in a fixed amount and cannot be easily replaced. These energy sources must be extracted from the earth, and they include things like nuclear fuel and fossil fuels, which are things like coal, oil, and natural gas. Fossil fuels were formed in the geologic past from the remains of ancient organisms. Plants and animals that died millions of years ago became buried in the soil, partially decomposed, and were exposed to a lot of heat and pressure.

This heat and pressure chemically rearranged the energy contained within their bodies into the fossil fuels we use today. Because they take so long to form, we have a finite amount of non-renewable resources in the earth right now. The lifespan for fossil fuels is a broken loop, a one-way ticket. First, the fossil fuel is found; then it has to be extracted. Extracting fossil fuels can involve destructive mining processes that can pollute surrounding habitats. It then has to be transported to wherever it will be used, and using fossil fuels means burning them, which releases greenhouse gases and other pollutants into the atmosphere.

Also, it can take energy to refine and process some types of fossil fuels so that they're more helpful to us, like turning crude oil into petroleum gas, diesel, and jet fuel. Burning the fossil fuels transforms that energy into a less organized form of energy, like heat and ash.
