Renewable and Nonrenewable Energy

Renewable and nonrenewable resources are energy sources that human society uses to function on a daily basis. The difference between these two types of resources is that renewable resources can naturally replenish themselves while nonrenewable resources cannot. This means that nonrenewable resources are limited in supply and cannot be used sustainably. There are four major types of nonrenewable resources: oil, natural gas, coal , and nuclear energy. Oil, natural gas, and coal are collectively called fossil fuels.

They are found in underground layers of rock and sediment. Pressure and heat worked together to transform the plant and animal remains into crude oil also known as petroleum , coal, and natural gas.

The plants and animals that became fossil fuels lived in a time called Carboniferous Period , around to million years ago. The energy in the plant and animal remains originally came from the sun; through the process of photosynthesis, solar energy is stored in plant tissues, which animals then consume, adding the energy to their own bodies.

When fossil fuels are burned, this trapped energy is released. Natural gas is widely used for cooking and for heating homes. Natural gas can be pumped out through the same wells used for extracting crude oil.

Coal is a solid fossil fuel that is used for heating homes and generating power plants. It is found in fossilized swamps that have been buried beneath layers of sediment. Since coal is solid, it cannot be extracted in the same manner as crude oil or natural gas; it must be dug up from the ground.

Nuclear energy comes from radioactive elements, mainly uranium , which is extracted from mined ore and then refined into fuel. Unfortunately, human society is—for the time being—dependent on nonrenewable resources as its primary source of energy. Approximately 80 percent of the total amount of energy used globally each year comes from fossil fuels.

We depend on fossil fuels because they are energy-rich and relatively cheap to process. But a major problem with fossil fuels, aside from their being in limited supply, is that burning them releases carbon dioxide into the atmosphere. Rising levels of heat-trapping carbon dioxide in the atmosphere is the main cause of global warming.

Alternative energy sources, such as wind and solar energy, are a possible solution to the depletion of nonrenewable sources. Both of these clean energy sources are available in unlimited supply. Also called diesel oil and diesel fuel.

However, over time, there has been a shift in demand for cheaper and cleaner fuel options, such as the nonrenewable energy source of natural gas, and renewable options like solar power and wind energy.

Each energy resource has its advantages and disadvantages. Explore nonrenewable and renewable options with this collection on energy resources.

What is a fossil fuel and what is being done to make fossil fuels more environmentally friendly? Fossil fuels form from the remains of prehistoric dead animals and plants due to geologic processes.

Non-renewable energy comes from sources that will eventually run out, such as oil and coal.

Energy Resources and Systems

From the perspective of ongoing sustainable use of energy resources, we have classified energy sources into two categories: renewable energy and nonrenewable energy. Renewable energy [renewable]: Replaced or replenished naturally in the same amount or less time as it takes to draw the supply down. Most renewable energy sources are also clean in that they do not require combustion, which releases pollutants and greenhouse gases A gas in the atmosphere that absorbs and emits radiation within the thermal infrared range. This property allows the earth to maintain its warm temperature which supports life on earth. Water vapor, carbon dioxide, ozone, and methane are good examples of gases with this property. When the concentration of these gases gets too high, the earth warms beyond its normal range and many catastrophic climate shifts occur.


oil, coal, and ore that are removed from the ground. Separated into two broad categories: ▫ Renewable resources. ▫ Nonrenewable resources.

Nonrenewable Resources

The is defines as the sources of energy which are produced continuously in nature and are essentially inexhaustible at least in the time frame of human societies. These energy sources replenished themselves naturally in a relatively short time and therefore will always be available. The Nonrenewable Energy resources are defined as the energy resources which have been accumulated over the ages and not quickly replenishable when they are exhausted.

Conventional energy source based on coal, gas, and oil are very much helpful for the improvement in the economy of a country, but on the other hand, some bad impacts of these resources in the environment have bound us to use these resources within some limit and turned our thinking toward the renewable energy resources. The social, environmental, and economical problems can be omitted by use of renewable energy sources, because these resources are considered as environment-friendly, having no or little emission of exhaust and poisonous gases like carbon dioxide, carbon monooxide, sulfur dioxide, etc. Renewable energy is going to be an important source for power generation in near future, because we can use these resources again and again to produce useful energy. Wind power generation is considered as having lowest water consumption, lowest relative greenhouse gas emission, and most favorable social impacts. It is considered as one of the most sustainable renewable energy sources, followed by hydropower, photovoltaic, and then geothermal.

Renewable and nonrenewable resources are energy sources that human society uses to function on a daily basis. The difference between these two types of resources is that renewable resources can naturally replenish themselves while nonrenewable resources cannot. This means that nonrenewable resources are limited in supply and cannot be used sustainably.

    A non-renewable resource also called a finite resource is a natural resource that cannot be readily replaced by natural means at a quick enough pace to keep up with consumption.
