Welcome to my 'All the Types of Energy' post!
First of all, I must congratulate you for taking the time to do your research on this topic of green living. We rely heavily on non-renewable energy, but is this the right option for us considering the current climate crisis?
As a qualified teacher, I am passionate about education and the impact it can have on bettering our future. It is down to us individuals to do our research and make small changes to the way we live our lives.
These small changes are easy to make and can have a big impact on our health, the health of our family and our environment. This website is designed for everyday people looking to make these changes. Here you will learn a legitimate way to go green.
Let me be completely transparent with you, I am not here to pitch or sell anything to you. I am here to reveal and to assist you on your journey of going green!
Non-renewable energy comes from sources that will run out or won't be replenished for thousands or maybe many years; i.e. fossil fuels such as coal, gas, and oil. Fossil fuels were created from the remains of marine creatures that decayed many years ago, under huge amounts of pressure and warmth.
Non-renewable energy sources are often used for all types of things. Most fossil fuels are burned to make energy and electricity. Over 70% of the energy utilized in industrial processes comes from non-renewable sources, while fossil fuels also are used for several household purposes.
There are numerous downsides to non-renewable energy, including their negative environmental impact and therefore the fact they're in limited supply. Let's take a look at the advantages so we can see the attraction to them.
- Lots available: Humans have invested tons of your time, effort, and money into obtaining fossil fuels, so we now have a ready supply.
- Easier to find: Fossil fuels are often found everywhere the planet, with many areas already identified as being rich in these resources.
- Very efficient: Fossil fuels can generate tons of energy, even from just a little amount of fuel.
- Simpler to transport: Fossil fuels are often easily transported, e.g. using underground pipes to maneuver oil and gas.
- Easy set-up: A fuel plant is often found out at any location, as long as there's an outsized quantity of fuel to get power.
- Environmental pollution: Burning fossil fuels release CO2, which is directly linked to heating – so fossil fuels are very damaging to the health of our planet.
- Huge amounts of fuel reserves: to stay power stations working, you would like truckloads of fuel. this will make energy generation very expensive.
- Public health issues: due to all their nasty pollution, burning fossil fuels can cause lung problems and asthma attacks in humans.
- They will run out: Once the earth's supplies of fossil fuels are spent, they can not be renewed (at least not for several hundred million years), so we cannot be ready to use them for our rising power needs.
- Oil spills: the large tankers transporting oil sometimes crash and spill their contents into the ocean and nearby coast. this is often disastrous for the ocean and land and may be deadly for the animals that live there.
- Rising costs: As just a couple of countries hold an outsized number of fossil fuels, fuel prices can rise all of sudden.
- Health risks to workers: Mining for coal or drilling for oil is often very dangerous, leading to an outsized number of diseases, injuries, and deaths per annum.
Coal may be fuel. It comes from the remains of plants that died about 100 to 400 million years ago. Coal may be a non-renewable energy source because it takes many years to make. it's a non-renewable energy source and produces a big amount of greenhouse emission emissions when burnt.
What is coal?
Coal may be a rock created from buried plants that lived and died many many years ago when the surface was covered by swampy forests.
How was coal formed?
Over 100 million years ago, dead plant matter would fall and accumulate at rock bottom of swamps on the surface. Layers of water, rock, and dirt built up above the layers of dead plants over time. The warmth and pressure this created reduced the oxygen content of the plant matter, leaving rich hydrocarbon deposits. As a result of these changes, what had once been plant matter gradually became coal.
If coal is all that way underground, how can we catch on out?
Coal is often removed in two ways:
- Surface mining is employed when a seam is within around 200 feet of the surface. The soil and rock covering the coal (called the overburden) are removed, and specialist equipment is employed to show the coal seam.
- After mining is complete, the overburden is replaced, covered with topsoil and fertilizer, and seeds are planted. This helps to revive the biological balance and stop erosion.
An advantage of surface mining is that it's cheaper than underground mining
Surface mining can leave permanent scars on the landscape and this is one of the downsides.
Why isn't coal an honest choice of energy source?
Coal has the very best level of carbon of all the fossil fuels. This suggests it produces a better amount of greenhouse emission emissions from energy use, which is bad news for our planet.
However, coal still produces significant amounts of pollution and gas emissions when burnt, including sulfate and nitrogen which will contaminate waterways and cause haze and smog. Coal also produces mercury, which builds up within the fatty tissues of animals and fish – this will cause harm to humans who consume these species.
Oil (also referred to as petroleum) may be a fuel formed from the remains of small sea plants and animals that died many many years ago. Once refined, oil is often wont to make products like gasoline, diesel, and jet fuel.
How is oil (petroleum) formed?
Hundreds of many years ago (before dinosaurs existed), when tiny sea plants and animals died, they sank to rock bottom of the oceans. Thousands of feet of sediment and sand, which turned to rock buried them.
As the layers increased, pressure and warmth built up, causing the organic interest to be weakened into compounds called hydrocarbons (made of hydrogen and carbon atoms). Finally, an oil-saturated rock – a touch sort of a wet sponge - was formed.
Can we use oil exactly because it comes out of the ground?
No, so as for petroleum to become usable products – like gasoline for our cars – it first must be processed at a petroleum refinery.
The journey goes like this:
- Oil is pumped from a well then transported to a petroleum refinery – often by ship, barge, pipeline, truck, or train.
- At the refinery, huge round tanks store the oil until it's able to be processed.
- Oil refineries then clean and separate the petroleum into various fuels and by-products. this will be done by a heating process called distillation, which separates oils with different boiling points.
- Oil refineries also remove contaminants from the oil, like removing sulfur from gasoline.
What products can we get from oil?
The most important product to return from oil is gasoline, which is employed to fuel cars. Other petroleum products include diesel, fuel oil, and jet fuel for airplanes.
These products are mainly used as energy sources within the transportation and industrial sectors, but petroleum products also are used for commercial and residential purposes.
Natural gas may be a non-renewable fuel formed from the remains of small sea plants and animals that died 300-400 million years ago. Approximately 90% of gas consists of methane, but it also contains other gases like propane and butane.
How is gas formed?
300-400 million years ago, the remains of small sea plants and animals sank to rock bottom of the oceans, where they were buried by sediment that became rock. Over the years, the layers of rock became thousands of feet thick, putting the energy-rich plant and animal matter under tons of pressure. Eventually, the pressure and warmth changed this organic mixture into oil (petroleum) and gas.
Natural gas became trapped within the rock layers – very similar to water is trapped during a wet sponge. Natural gas is often tricky to seek out, as it's generally trapped in rocks located deep underground. to seek out gas deposits, geologists may:
The journey goes like this:
- Look at surface rocks to seek out clues about underground formations.
- Set off small explosions or drop heavyweights on the surface, so as to record the sound waves as they recover from the underground rock layers.
- Measure the gravitational pull of rock masses deep within the world.
If a site looks promising, wells could also be drilled to seek out the gas deposits – as these wells average almost 9000 feet deep and may cost many dollars per foot to drill, it is vital to settle on gas sites carefully!
What happens to gas after it comes out of the ground?
Once it has been taken from the bottom, gas is shipped to a processing plant to be cleaned of impurities and separated into its different components – this is often mostly methane, also as other gases like propane and butane.
Are there other sources of natural gas?
Yes. Gas also can be found in seams of coal, called coalbed methane, also as within the methane produced in landfills. While gas is taken into account a non-renewable energy source, landfill gas may be a renewable source of methane, because it comes from decaying rubbish.
What is propane?
Propane may be a gas that comes from gas and petroleum (oil). it's a clean-burning fuel that features a lot of various uses, including:
- Making products and fuelling industry
- Heating barns and operating farm equipment
- Fuelling hot air balloons
- Heating homes
- Fuelling barbecues and appliances
- Fuelling machinery
Nuclear energy comes from the nucleus of atoms. The energy is released by fusion (nuclei are fused together) or fission (nuclei are split apart). Nuclear plants use fission of a radioactive element called uranium to get electricity.
Where does atomic energy come from?
Atoms – the particles that structure every object within the universe – contain neutrons, protons, and electrons. They contain a nucleus, which is where atomic energy comes from. atomic energy is released from an atom through either:
Nuclei of atoms are combined or fused together and this is called Nuclear fusion. This is often how the Sun produces energy. Nuclei of atoms are split apart is nuclear fission. This is often the tactic employed by nuclear plants to get electricity.
What is uranium?
Uranium may be a radioactive element that was formed when the world was first created. It occurs naturally in certain sorts of rock.
Uranium is one of the few elements that's easily fissioned, so it is employed as fuel by atomic power plants. Although uranium is found everywhere the planet, it's still a non-renewable energy source.
What happens during fission during a nuclear plant?
A particular sort of uranium – called uranium-235 – is most ordinarily used for energy production, as its nucleus splits easily when it's bombarded by a neutron.
Here's what happens during a fission reaction:
- The nucleus of a uranium atom is bombarded by a neutron, causing it to separate into two atoms
- At an equivalent time, energy is released as heat and radiation
- As a result of the fission reaction, more neutrons are released
- These neutrons then start bombarding other uranium atoms, therefore the process keeps repeating itself. this is often called a sequence reaction
All the Types of Energy: The Final Verdict!
While there are some clear advantages to using fossil fuels to meet our energy needs, it's clear that the negatives far outweigh the positives! Without an alternate source of energy, we could soon be facing a serious energy crisis – and a disaster for our planet's health.
