What Are Some Examples Of Renewable Energy
What Are Some Examples Of Renewable Energy – Living and non-living natural resources used by human society for its daily activities can be classified into renewable and non-renewable natural resources.
Renewable resources, also known as flow resources, are natural resources that can replace parts lost through consumption and use.
What Are Some Examples Of Renewable Energy
The regeneration process occurs through natural reproduction and other repetitive processes. On the other hand, non-renewable natural resources, also called limited natural resources, are natural resources that naturally cannot be easily replaced at the rate of consumption.

What Is A Renewable Resource?
Petroleum oil, also known as crude oil, tops the list of non-renewable natural resources that can be produced in liquid form. Oil is a fossil fuel that naturally takes millions of years to form.
Fossil fuels are created when marine animals and plants die and their remains are buried under sand, silt and mud.
Over a long period of time, the high temperatures and pressures underground turn the waste into fossil fuels. Because this resource cannot be replaced faster than people.
Crude oil is found in rocks or layers of the Earth’s crust. Currently, there are large pockets of this non-renewable energy source underground all over the world.

This source of energy is obtained by drilling vertical wells into the ground or seabed. The oil is pumped to the surface, transported to a refinery, and used to make a variety of products, including diesel, gasoline, jet fuel, and propane. Oil is also a chemical component of many plastics and composites.
It is believed that fossil energy sources such as oil will eventually become too expensive to recover and human society will become dependent on other energy sources. Since the design of internal combustion engine technology, oil and other fossil fuels have been in constant demand.
Today’s economy, largely based on fossil fuels, is criticized for its lack of innovation. When new oil fields are discovered, the oil reserves are quickly depleted.
Natural gas, also known as fossil gas, is a naturally occurring, non-renewable source of hydrocarbon gas located beneath the earth’s crust.
What Is Meant By A Renewable Source Of Energy ? Give Two Example Of Renewable Sources Of Energy
Natural gas consists mainly of methane. However, it may contain other gases such as ethane, propane, butane and small amounts of carbon dioxide, hydrogen sulfide and nitrogen.
Natural gas is odorless and colorless, so a sulfurous smell is added to detect leaks.
Because natural gas is a fossil fuel, it is formed when animal and plant layers are exposed to high pressure and heat underground over millions of years.
This non-renewable resource is found deep underground in rocks and other hydrocarbon deposits such as coal. Natural gas is used as an energy source in electricity production, cooking and heating. It is also used as motor fuel and as a chemical raw material in the production of plastics and other organic chemicals.
Examples Of Renewable Resources
Natural gas is treated to remove impurities such as water before being used as a fuel. Like crude oil, people are quickly depleting natural oil reserves when new gas reserves are discovered. Are rare earths disappearing?
Earth minerals are irreversible solid chemical compounds with naturally occurring crystal structures and fairly defined chemical compositions.
Earth’s minerals are found in abundance in the Earth’s crust and include gemstones, salt, diamond, clay, granite, quartz, shale, and gravel.
Humans can only extract minerals from the earth that have been concentrated as a result of natural geological processes such as pressure, heat, atmospheric weathering, organic action and other processes that are economically viable in mining.
Renewable And Non Renewable Examples
The geological processes that form and concentrate minerals on Earth typically take tens of thousands or millions of years through plate tectonics, crustal reworking, and tectonic subsidence.
The earth’s mineral resources, which man can use economically, are not renewable in man’s time. Minerals are rarer and more depleted in some places than others. Minerals are found in very small concentrations.
The process required to separate minerals from natural rock is complex and requires multiple mining and purification steps. These minerals are in high demand in certain industries such as the electronics industry. Coal – is coal renewable or non-renewable?
Coal mainly consists of carbon, hydrogen, sulphur, nitrogen and oxygen. This non-renewable energy source is a fossil fuel when dead plant material breaks down into peat.
How Should The Use Of Non Renewable Natural Resources Be Reduced So That Sustainable Ecological Development Is Possible?
Over millions of years, high pressure and heat turn dead plant material into carbon. This process is called carbonization. The large coal deposits originate from ancient wetlands that settled on the surface millions of years ago.
There are four types or grades of coal – anthracite, lignite, bituminous and sub-bituminous. The classification is based on the amount of carbon in the coal, with anthracite being the highest and lignite being the lowest. Coal is mainly used as fuel.
In 2020, coal produced a third of the world’s electricity and a quarter of the world’s primary energy. Burning coal also produces valuable by-products that are used in the production of plastic, cement, bitumen and other products. Coal is produced by underground and surface mining.
Because it takes millions of years to form, coal is classified as a non-renewable energy source. An international initiative is currently underway to end the use of coal due to its negative health and environmental effects. The coal industry is already in decline as people want to switch to environmentally friendly renewable energy sources.

Water resources are versatile. Water can be a renewable or non-renewable resource depending on the scenario. Groundwater is a very important natural resource worldwide, and it provides a significant part of public water resources.
People living in rural areas get most of their water from underground sources. Groundwater reserves (deep waters) are considered non-renewable natural resources because they are depleted on a human time scale.
Groundwater reserves are replenished by rain. However, it gradually slows down much more than groundwater consumption.
The development of groundwater natural resources takes several years. In addition, people can take only the economically useful part of groundwater without causing harmful consequences. Continuous groundwater extraction worldwide is causing massive depletion of groundwater reserves.

This pumping can lead to lower lakes, reduced river flows and shrinking wetlands. This, in turn, can reduce water resources and affect the aquatic environment.
All these factors affect the unstable and irreversible state of groundwater. More efforts are being made to promote the sustainable use of groundwater. Is soil a renewable or non-renewable resource?
The concept of land surface or soil renewal is also multifaceted. Soil can be classified as a renewable or non-renewable natural resource depending on several factors and the reference area.
Water covers more than 70% of the earth’s surface. The remaining part is the surface of the earth and serves as the basis of life on earth.
Renewable Resources, 10 Examples Of Renewable Resources
Human societies and their activities affect the health of the earth’s surface or soil and cause permanent damage. This significantly reduces land use. Because of this, soil and land are non-renewable natural resources.
Soil has many important functions for humans, animals and plants. These soil functions can be divided into four main groups. These include habitat, regulatory, scientific and economic functions.
Regulatory functions include storage of nutrients and water, filtering of pollutants, and buffering of water and dissolved substances. Habitat functions include providing a wide range of microorganisms, animals, and plant biodiversity. Plants use soil as an anchor to produce and maintain above-ground biomass that provides food for humans.
Scientific activities include recording past data. This archive is an important source of information for archaeologists and other researchers. The economic activity includes the production of various materials such as gravel, sand, clay, peat and wood.
Advantages And Disadvantages Of Non Renewable Energy
Human processes, including soil compaction, erosion, erosion, desertification, and non-renewable agriculture, can compromise soil fertility and stability. Soil fertility takes thousands of years to develop, and thousands of years to recover when disturbed. These aspects contribute to keeping the earth as a non-renewable natural resource.
According to the US Energy Information Administration, plastic is a non-renewable resource because it is made from natural gas liquids, liquefied petroleum gas (LPG), and natural gas.
These fossil fuels are the most commonly used non-renewable energy sources. However, plastic is recyclable, meaning it can be washed and recycled into other products. Plastics are malleable and can be molded, pressed or extruded into various solid shapes.
The adaptive nature of plastics and other properties, including lightness, strength, flexibility and cost-effectiveness of production, mean that this non-renewable resource has many applications.

Applications include packaging materials, construction (doors, pipes, drains), medical devices, textiles, consumer goods, electronics, transportation and machine parts. It should be noted that plant-based bioplastics are renewable natural resources. Why is nuclear power not renewable?
Nuclear fuel (isotopes) such as uranium U-235 is rare in its natural state, so even small amounts travel long distances and cannot be recovered.
For example, one kilogram of uranium can produce more energy than three million kilograms of coal. Nuclear fuel, such as uranium, is found in certain rock formations.
This material is used as a fissile material in slow-reaction nuclear power plants. Nuclear fission reactors split atoms and release large amounts of energy from the core of enriched uranium.
Renewable And Nonrenewable Resources
Nuclear reactions generate heat, which ignites the water in a nuclear reactor. The water turns into steam and uses turbines and generators to generate electricity.
One major drawback of nuclear fission power is radioactive nuclear waste.
