Renewable and Non-Renewable Energy

You should be able to answer all of these after reading through the content on this page. I suggest writing or typing out your answers, but if nothing else, say them out loud to yourself. This is to help you reflect on important content, and will help you prepare for this week's quiz. What is the difference between renewable and non-renewable energy? Explain how wind, biomass, and hydropower get their energy from the sun.

Identify benefits and drawbacks of solar, wind, hydro, and biomass. What is the difference between a carbon-free and carbon-neutral energy source? Renewable energy is defined by the U. Non-renewable energy is energy that cannot restore itself over a short period of time and does diminish.

It is usually easy to distinguish between renewable and non-renewable, but there are some exceptions more on that in a minute. You are welcome to read the sub-headings for each source, but that is not necessary. The key points are summarized below. Please note that these readings only scratch the surface of the world of renewable energy sources! You could spend your whole career learning about them as some people do , and still have more to learn.

I encourage you to learn as much as you can about these and other sources. It may sound like hyperbole, but you can never know too much about energy.

It figuratively and literally makes the world go 'round. Please note that this does not provide a comprehensive list of pros and cons, but will give you a solid idea of many of them:.

All of these sources renew themselves over short periods of time and do not diminish. And though intermittent, none of these sources are going to disappear in the foreseeable future. They are textbook renewable energy sources. Okay, so what about biomass and biofuels? They are both derived from living or recently living things trees, corn, algae, sugarcane, etc.

Can you think of any examples of non-renewable biomass? Nearly all forms of biomass and biofuels are renewable. Corn-based ethanol is the most-used source of bio-based energy in the U. Corn can be grown in the same field year after year, so it is renewable. Whether or not it is sustainable is another question, which will be addressed later. The primary source of bioenergy in Brazil is sugarcane.

Contrast this with the U. Sugarcane grows year round in Brazil, so is definitely renewable. There are many other biomass sources that fit our definition of renewable, including animal dung, algae for biodiesel , jatropha nut, soybean, switchgrass, and more.

Wood is used around the world as a source of heat, particularly for cooking. Most trees and shrubs regrow relatively quickly, so they are generally considered renewable. But even a fast-growing tree like an oak up to two feet per year, according to the National Arbor Day Foundation has limits. Though most biomass sources are considered renewable, keep this in mind: if you harvest a renewable resource faster than it regenerates, it will not be able to renew itself over time.

We will revisit this point in a later lesson, but it is important to remember. Most renewable energy sources are carbon-free. This means that they do not emit any carbon dioxide when they generate energy. Solar, wind, and hydroelectric are carbon-free. Nuclear, though not renewable, is also considered a carbon-free energy source, because unlike coal and natural gas, it does not burn. As noted in a previous reading, nuclear energy generates heat through fission, not combustion.

Biomass and biofuels are often considered carbon-neutral because they emit carbon dioxide when they are burned. So, why are they carbon neutral? Note that the energy unit they use is Mtoe, which stands for million tonnes of oil equivalent. A Mtoe is equivalent to about 0. In other words, there are about 25 Mtoe in a quad. The amount of energy is not important for our purposes, but please take note of the percent of the total that each energy source provides.

Non-renewable energy sources diminish over time, and are not able to replenish themselves. In other words, they are finite, and once they are used, they are effectively gone because they take so long to reform. You have already read about the four non-renewable energy sources: coal, oil, natural gas, and nuclear. Let's start with coal, oil, and natural gas, which as you read earlier are referred to as fossil fuels.

Fossil fuels were created from the remains of dead plants and animals. The source material is renewable it's biomass! Fossil fuels are forming somewhere under your feet right now, but don't hold your breath waiting for them to finish.

The nuclear energy we use comes from an isotope of uranium called U Unlike fossil fuels, U has cosmic origins: it was formed by one or more supernovae around 6 billion years ago, about 1.

Again, this is not renewable on a human timescale. Recall that they are made mostly of hydrogen and carbon, and the carbon mostly ends up as CO 2. Nuclear is considered carbon-free, because it is not burned, and it is not made of carbon. Remember that energy is extracted through fission, or splitting of atoms.

This generates heat, but no emissions. It is important to note that it does result in very dangerous and long-lasting radioactive waste, but that will be addressed in a future lesson. All of the carbon dioxide emitted from coal, oil, and natural gas was originally pulled from the atmosphere to make the plants from which is was derived grow. In other words, the amount of carbon dioxide emitted is no more than the amount of carbon dioxide it originally removed from the air.

Why are they not carbon-neutral energy sources? We hear a lot about renewables and natural gas in the U. Solar, despite its massive growth and growth potential, is only 1. We have a long way to go, people! Now that you have completed the content, I suggest going through the Learning Objectives Self-Check list at the top of the page. Skip to main content. Figure 1. This is printed on a bag of wood pellets, which are used for heating in a pellet stove. These emit CO2 when burned, but effectively do not impact the level of carbon dioxide in the atmosphere.

The pellets are made of leftover sawdust from timber operations. In , the total was 6, Mtoe distributed in the following way: Coal: Credit: International Energy Agency. Brazil is the world's leading producer of sugarcane and sugar-based ethanol. Even the waste material from the sugarcane extraction process can be used for energy generation, or to make secondary products like compostable plates and silverware.

Check Your Understanding All of the carbon dioxide emitted from coal, oil, and natural gas was originally pulled from the atmosphere to make the plants from which is was derived grow.

Difference Between Renewable and Non-Renewable Resources

That's like asking the difference between having an endless supply and having a limited supply. Will this planet eventually run out of oil? So oil is a nonrenewable resource. A natural resource is something supplied by nature that helps support life. When you think of natural resources , you may think of minerals and fossil fuels.

Use of this web site signifies your agreement to the terms and conditions. Optimization and a comparison between renewable and non-renewable energy systems for a telecommunication site Abstract: The renewable energy based hybrid energy system is one of better solutions to reduce the environment pollution. Renewable energy offers power supply for locations that are remotely located and also allows economical way of producing power for small power applications.

The words renewable and non-renewable resources are thrown around a lot on the news and even social media platforms, but do Americans really understand what they mean? The idea that you could be causing major harm to the planet as a small business may sound dramatic. In fact, the mere idea that you can make a significant difference by changing your energy source can sound extremely daunting. However, it is all true?

But when we get down to it, what are they and what are the major differences between the two? Plus, there are more and more sustainable energy types being tested every day.

Difference Between Renewable and Nonrenewable Resources:

The main points of distinction between Renewable and Non-Renewable resources are the amount at which they are used, and the rate of exhaustion, their costs, effects on the environment. These resources are used and beneficial to us in many ways, like plants provide us medicine, fruits, flowers, vegetables, paper, rubber, etc. There are many criteria on which natural resources can be classified, and one of them is on the ground of the renewability of these resources. Renewable resources can be renewed or regain once used, whereas Non-Renewable resources are just the opposite and cannot be regained once used. In this content, we will review the characteristic points between renewable and non-renewable resources, with a brief description of them. Basis for Comparison Renewable Resources Non-Renewable Resources Meaning Renewable is the natural resources around us, which can be used numerous times and get replenished. Non-Renewable resources were formed deep in Earth's crust millions of years ago, hence once used they disappear forever.
