What does renewable resource mean?
A resource of energy that is classified as renewable must be in use and replenish itself in the course of an organic process. While many energy sources are categorized as renewable, only a small percentage are. Certain types of energy are extremely long-lasting, but they’ll eventually wear out.
One of the examples is the ocean or sea. If we add food energy into the equation, then we can declare it renewable as we have taken fish from the sea for hundreds of years.
It’s also coming towards the conclusion of its useful existence because humans have been able to take too much from it, assuming that the resources are inexhaustible.
Which of the following can be considered a renewable resource?
- Sun — yes, the sun is a renewable source and will be shining for billions of years.
- Oceans — yes, the wave power will not stop since the moon’s gravity drives the moon’s gravity.
- Wood — no, trees are being used more quickly than re-planting could.
- Coal — is not the case, but the earth has a limited amount of coal deposits.
- Gas and oil — no, gas and oil will run out in the next 100 years, or at least that’s the plan.
- Wind — yes, so long as there are sun and weather conditions, there will be winds.
- Minerals — no, minerals require millions of years to form, and we can use them extremely quickly.
- Air — no, not exist, but our oxygen comes from oceans and plants – they are dying.
- Soil — no, in many countries, there is severe soil erosion due to over-farming.
- Sand — no, massive quantities of sand are used to make concrete. We are now running out of sand.
- Water — no, water is going to be in short supply in the next 50 years.
- Biomass — no, tip – anything that starts with the word “bio” in the title isn’t renewable.
- Nuclear — no, radio-isotopes decay eventually
Which resource is renewable?
In essence, three sources in the world can be considered renewable.
- Power from wind
- Ocean wave energy
The sun’s energy drives the wind, too, since it is the difference in temperature between the air pockets which generate currents. However, wave energy is different because it is caused by lunar gravity when it revolves around the Earth.
However, none of these known renewable resources is obtainable by humankind without machines made using energy derived from fossil-based fuels. Of course, fossil fuels cannot be regenerated.
Which resource is both renewable and inexpensive economics?
Sunshine is the largest renewable energy source on earth. The amount of sunshine energy that falls on the planet in just 24 hours to supply the entire world with electricity for a whole year! Making use of the power is the difficult part.
Heating water with solar energy is highly efficient, with over 75 percent for certain vacuum tube collectors. Hot water is a welcome feature. However, it’s electricity that is becoming more important. Sunlight is converted into electricity. They aren’t that efficient, with around 17 percent at their maximum.
The installed cost per Kilowatt generated by solar energy has slowed dramatically over the last ten years but is still not as low as $3/watt. However, solar PV (photo photovoltaic) systems cannot compete with high-power wind farms in terms of kW per kW.
In the present, wind turbine power systems remain the most affordable renewable energy source economically.
Renewable and nonrenewable resources:
Is Sun a renewable resource?
I’ll discuss the Sun first because the sunlight’s power is essentially the most energy that exists. As a result, all forms of energy originate through the Sun regardless of whether it’s the coal that comes from trees, oil extracted from vegetation, or the wind that powers the turbine.
The term “wind” refers to whether that is driven by solar radiation and the Sun’s heat. Ocean waves may be the only exception. The seas pull backward as well as forwards by the moon’s gravity.
The primary use for Sun’s energy is through solar PV cells action, which generates electric power that we can then use at home. In addition, Sun’s warmth can create heat for water that we can use for our needs.
There is indeed nothing that is 100% renewable, including sunlight. In the next 4 billion years, the Sun will cease to exist. But, for the duration of humanity, we can think of it as renewable.
Is water both renewable and nonrenewable?
Water can be considered to be both renewable as well as nonrenewable. The planet’s water is in a continuous cycle in which precipitation is deposited on the mountains that run towards the ocean and then evaporate back into the atmosphere.
The most significant issue for the near future concerns water distribution. Dispersion of the water and the enormous quantities used to rear animals and irrigation of crops.
In the near future, nations that have been blessed with ample water may face an acute shortage of water, which could lead to armed conflicts in certain instances. The reasons for this are complex and have to relate to the changing climate as well as poor management and environmental pollution.
Are minerals renewable?
Minerals are plentiful and come in various forms, including diamantes and antimony. They are incredibly long-lasting, and if we didn’t use them, they would last as long as the Earth.
However, that’s not the case. The demand for minerals is increasing, and certain minerals are in short supply already.
Minerals aren’t renewable at all as they require thousands of years for them to develop within the Earth’s crust, and humans are consuming them at a faster rate than ever.
Is Diamond a renewable resource?
Even though diamonds are among the most durable natural substance that has ever been discovered by mankind, it isn’t sustainable in any way. I’m not entirely sure if diamonds should be considered a “resource” in any way. It is true that we use them to embellish our designs and in the industry, but that’s taking too far from the meaning my opinion.
The only way diamonds can be revived by the massive heat and pressure created within the Earth’s crust. This is this process can take millions of years.
Is Forest renewable or nonrenewable?
There’s lots of hype regarding biomass as a renewable fuel. This is not true. Many people believe that wood pellets, as an instance, are composed of wood scraps or shavings which is left over after cutting and shaping wood.
The majority of wood pellets are made of trees that are designated low-quality and unsuitable for use in construction. This means that sub-standard trees are removed and transformed into biomass.
Sure, more exotic trees can take longer to mature, and an eco-habitat, such as that of the Amazon rain forest, can take several hundred years to grow.
Is soil a renewable resource?
The soil can be considered a resource that is finite, which means that its degradation and loss aren’t reversible in the course of human life.
Why is soil called a renewable resource? Soil is regarded as a renewable resource due to the fact that it is able to be replenished at a human scale. When soil is lost due to erosion, it can be recovered relatively easily.
Is sand a renewable resource?
Someone asked me once what the number of stars that exist in the Universe, and they explained it the following way: “There are more stars than particles of sand in the amount of sand that covers the entire area of France at 1 meter deep!”
This is quite a plenty of sand! It is common to think of sand as endless. Isn’t sand a renewable resource? Actually, it is not.
China produces the equivalent to Chicago. Chicago city Chicago every year. And the quantity of concrete required is massive. Concrete doesn’t just require sand but also the right kind of sand. It needs one with sharp edges like the ones found on beaches of seas all over the globe.
Sand from the desert isn’t good since it has been carried around by winds for thousands of years and has turned into a rounded. This means that it isn’t bonded to its neighboring grains and cement particles. In essence, it’s not sufficient for construction.
The scarcity of building sand is critical. The pirates keep taking this sand from beaches all over the globe, and an underground market has emerged to purchase this essential yet precious resource.
Is Metals a renewable resource?
Metals like copper and lead, tin as well as aluminum, gold, and silver are all elements. Metals are not renewable. Steel is made up of the element iron. Iron is non-renewable. Iron, titanium, and aluminum are the three elements with the highest amount of occurrence within the earth’s crust.
Is wood a renewable resource?
The biomass construction, ethanol, and biomass industries would like us to believe wood is a sustainable resource. In our lives, it’s not.
It’s true that you can grow a sapling for each tree that is cut down. Even the fastest-growing tree takes several years to develop. On a global scale, we plant the equivalent of a full tree every couple of seconds!
It’s evident that we’re currently exhausting the entirety of the trees that are available. Once they’re gone, is that it, unless you find a magical solution, like artificial wood for construction, as an instance.
Is wheat crop both renewable and nonrenewable?
I’ve heard it said that wheat is an excellent example of both renewable and non-renewable resources. However, I believe this is untrue.
The reality is that the wheat crop is exceptionally vulnerable, dependent on large amounts of water and an adequate amount of soil. Unfortunately, both resources decrease rapidly due to human activity and natural processes.
In the USA, droughts are becoming more frequent, and in certain states, the top soil’s depth is only one or a couple of inches. Genetically modified grain has been developed to improve productivity over the long run. The idea of humans interfering with natural processes in this manner is absurd and won’t be a good idea.
Is nuclear renewable?
The truth is that nuclear isn’t renewable. The decay of nuclear fuel takes time, emitting radioactive particles during the process. This loss of atomic particles generates huge heat required to create steam that drives electrical generators to power the grid.
It exaggerates the term renewable to include fuel which leaves an odor that’s poisonous to living things for a period of 10000 years, which is then placed underground or stored in space.
