Overview on Energy sources
Types of renewable energy sources
Over the past 150 years or so, humans have relied heavily on coal, oil and other fossil fuels to power everything from light bulbs to cars to factories.fossil fuels have been an integral part of almost everything we do. as a result, the greenhouse gases emitted by the combustion of these fuels have reached historically high levels. because they trap heat in the atmosphere, they could leak into space, causing the planet to overheat. hence the thought of renewables to keep our planet from being destroyed.
What are renewable energy sources?
Are some sources of emerging alternative energy existing in the solar, wind, biomass, other options include hydropower, waves, tides, Ocean Energy and geothermal energy (although it did not achieve a lot of growth and prevalent as the other).
What are the types of renewable energy sources?
Solar energy: sunlight is one of the most abundant energy resources available on our planet, as the amount of solar energy that reaches the Earth's surface in one hour is more than the total energy requirement on the planet for a whole year, and although it seems to be an ideal source of renewable energy, the amount of solar energy we can use varies according to the time of day, the season of the year, as well as geographical location.in most countries of the world that use it, Solar Energy has become an increasingly common means of supplementing our energy use.
Wind power: as we know, wind power is an abundant source of renewable energy, as electricity from this energy can be harnessed through the use of turbines to power generators that feed electricity into the National Grid, and although local or “off-grid” generation systems are available, not every property is suitable for local wind turbines.
Some people may object to how wind turbines look on the horizon and how they look, but low-priced wind power proves to be a resource too valuable to be denied, yet there was a problem with wind turbines that is that they pose a danger to birds and bats, with hundreds of thousands of these animals being killed every year because of these high turbines.
Hydropower: as a renewable energy source hydropower is one of the most commercially developed resources, by building a dam or barrier a large reservoir can be used to create a controlled water flow that drives turbines to generate electricity, this power source is often more reliable than solar or wind power, and it also allows electricity to be stored for use when demand
Large dams can also disrupt the ecosystems of some of the surrounding rivers and communities, damaging wildlife and displacing populations, as hydropower generation is vulnerable to silt accumulation, which can damage capacity and damage equipment.
Tidal power: this is another form of hydropower that uses tidal currents twice a day to power turbine generators, and although the tidal flow is unlike some other hydropower sources it is highly predictable and can therefore compensate for periods when the tidal current is low.
Geothermal energy: this energy has been used for thousands of years in some countries for cooking and heating, and on a large scale Earth tanks of steam and hot water can be exploited through wells that can reach a depth of one mile or more to generate electricity, and this energy is unlike solar and wind energy because it is always available, but it
By harnessing natural heat under the surface of the Earth, geothermal energy can be used to directly heat homes or generate electricity, and although it uses energy directly under our feet, geothermal energy is of little importance in most countries of the world, where geothermal is more freely available.
Biomass energy: this is the conversion of solid fuels made from plant materials into electricity, and although biomass basically involves the burning of organic materials to produce electricity, this does not mean the burning of wood, which is nowadays a cleaner and more energy efficient process, by converting agricultural, industrial and domestic waste into solid fuel, liquid and gaseous fuels biomass can be generated at
Energy sources non-renewable
What are non-renewable energy sources?
These natural resources are a major source of energy for a large number of industries, yet there are many negative aspects of non-renewable energy including: their negative environmental impact and the fact that they are limited in supply
Carbon is also the main element of fossil fuels, which is why the time period in which this fossil fuel was formed about 300 million years ago was called the carbon period, since all fossil fuels were formed in a similar way, hundreds of millions of years ago even before the appearance of dinosaurs the Earth had a different landscape, where it was covered with
What are the types of energy sources non-renewable resources?
It is a rock that originated from buried plants that lived and died hundreds of millions of years ago, and more than 100 million years ago these dead plant materials were falling and accumulating on the bottom of the marshes on the surface of the Earth.over time, layers of water, rocks and dirt have accumulated on top of the dead plant layers. the resulting heat and pressure from the oxygen content of the plant material have reduced, leaving rich hydrocarbon deposits. as a result of these changes, what was previously plant material has gradually turned into coal.
There are two ways in which we can mine coal: underground mining and surface mining, underground mining occurs when coal is located underground and sometimes 300 meters (1000 feet) deep, this is deeper than most Great Lakes, and they operate heavy machinery that cuts coal from the ground and brings it above the ground, and this can be dangerous work because cutting coal can release dangerous gases, gases can cause explosions or make it difficult for miners to breathe.
Surface Mining is used when coal is located near the surface of the Earth, and to get to the coal companies must first clear the area, then take the trees and soil, here the coal can then be cut off from the ground easily.
Oil (also known as petroleum) is a fossil fuel consisting of the remains of small marine plants and animals that died hundreds of millions of years ago, once refined the oil can be used in the manufacture of products such as gasoline, diesel and jet fuel, however we can not use the oil exactly as it comes out of the ground but must first:
Oil is pumped from the well and then transported to the oil refinery, often by ship, barge, pipeline, truck or train.
And in the refinery huge round tanks store oil until it is ready for processing.
Oil refineries then clean and separate the crude oil into different fuels and by-products, where this can be done by a heating process called distillation which separates the oils at different boiling points.
Oil refineries then also remove contaminants from the oil such as the desulfurization of gasoline, and here the oil becomes so efficient that we can use it as fuel.
It is a non-renewable fossil fuel consisting of some remains of small marine plants and animals that died about 300-400 million years ago, and almost 90% of natural gas is composed of methane, but it also contains some other gases such as propane and butane, and once the natural gas is taken out of the ground it is sent to a treatment plant
Natural gas can be difficult to find because it is generally trapped in rocks deep in the Earth, and to find natural gas deposits the journey goes like this:
Looking at surface rocks to find evidence about underground formations.
It then detonates small explosions or drops heavy weights on the surface of the earth to record sound waves bouncing off the layers of underground rock.
If the site looks promising, wells may be drilled to find natural gas deposits, where the average depth of these wells is about 9,000 feet, and can cost hundreds of dollars per foot to drill, it is important to choose natural gas sites carefully.
Nuclear energy is an important source of non-renewable energy, as this energy comes from the nucleus of atoms, and energy can also be released by nuclear fusion or nuclear fission, where these atoms (particles) that make up every body in the universe are made up of neutrons, protons and electrons.
