ToggleCan you live without electricity?
- Energy is what drives machines in factories. It is what provides homes, factories, buildings, and streets with lighting and heating. It is what operates medical equipment in hospitals. It is what operates the communications sector, information technology, and computers. If water is life, today energy and water are Life cannot be dispensed with energy in any way, regardless of the reasons. Loss of energy paralyzes movement, destroys cities, and stops the wheel of production. So what is energy in general and what are energy sources.
What is energy in general:
Energy is the ability to carry out an activity, and it is one of the most important basics for any society that desires development, progress, and continuity in a normal daily life, starting with home life with all its details, such as cooking, heating, cooling, etc., moving to means of transportation and transportation, all the way to companies, institutions, and factory management.
Human energy differs from other means of energy used to serve his needs. Man uses the burning of various types of food that he eats into energy that helps him move and carry on with his life activities, while Energy sources Others that serve his needs have several forms that we will talk about in detail.
What are the energy sources:
Coal :
Can you live without electricity?
Coal is used to obtain thermal energy, and the latter is used directly for heating or especially in producing electrical energy in thermal plants. Coal currently represents approximately 25 percent of total global energy consumption.
- Advantages of coal:
- Coal reserves could last for a few centuries.
- The resulting energy is very high.
- Relatively low cost.
- Disadvantages of coal:
- Its extraction and processing lead to pollution of soil, air and water.
- Combustion releases carbon dioxide.
- Particles released into the atmosphere can harm humans.
Petroleum:
It is the second most important source of energy that cannot be dispensed with at the present time in human life, from which gasoline, diesel, and many other materials that are used in car engines are derived, where they are converted into kinetic energy, and petroleum consists of the remains of microscopic marine plants and animals that It was buried and exposed to physical and chemical factors for millions of years.
- Advantages of petroleum:
- Relatively low costs.
- The resulting energy is high.
- Easy to move from one place to another.
- Disadvantages of petroleum:
- It will need to be replaced by other energy sources within fifty years.
- Combustion leads to the release of carbon dioxide, molecules, and toxic gases.
- Transporting it in containers leads to air pollution.
Natural gas :
Natural gas is used to produce thermal energy and is used in homes, either for cooking or heating. Natural gas is also used in thermal plants to produce electrical energy, and about 20 percent of the energy that the world currently consumes comes from natural gas.
Gas is formed in the same way as petroleum and under the same conditions, and gas is found in deep rock layers in the ground.
- Advantages of natural gas:
- The resulting energy is high.
- Relatively low costs.
- Less pollution than other energy sources.
- It is easy to transport through tubes.
- Disadvantages of natural gas:
- It is mostly composed of methane, which is considered a greenhouse gas.
- A highly flammable substance that may pose a danger during transportation.
Nuclear Energy :
Uranium is an important source of nuclear energy, as nuclear power plants rely on the nuclear fission process. In this process, a chain reaction occurs that results in the transformation of fissionable materials into new materials and the release of a large amount of energy. Nuclear energy is currently one of the most important energy sources in the world, and progress has been made in this field in recent years.
Advantages of nuclear energy:
- Fuel availability:There is a large availability of materials such as uranium and plutonium in the world.
- Limited environmental impact: Nuclear power plants take up less space than other energy sources, and reduce environmental impacts on land and water.
- Operational safety: In well-operated and monitored nuclear reactors, the possibility of accidents is very low.
- Reducing carbon dioxide emissions: The use of nuclear reactors reduces the release of harmful gases into the atmosphere, which contributes to reducing carbon dioxide emissions.
Disadvantages of nuclear energy:
- Production costs:The costs of constructing and operating nuclear plants are high.
- Limited final energy production:The final amount of energy available after the fission process is small.
- Difficulties in waste disposal:Safe disposal of radioactive waste produced by nuclear plants faces challenges.
- Military use:Nuclear technology can be exploited to develop nuclear weapons.
Despite the great advantages of nuclear energy, the challenges and risks associated with it must be dealt with carefully, and safer and more efficient technology must be developed.
solar energy:
Energy that comes directly from the sun is a primary source of energy for the planet, and most energy sources can be traced back to solar energy. Solar energy conversion processes occur in forests and plants, where it is converted into fruits, berries and other organic materials. Animals ingest these substances and turn them into heat and meat, and they also store some of them as fat. When these animals and plants die, the organic materials decompose and over time turn into gases, oils, and coal.
In general, it can be said that living without electricity is a difficult challenge in the current era, as electricity has become indispensable in most aspects of our daily lives.
Solar energy features:
- Unlimited Availability:Solar energy is infinitely available.
- Ease of installation:Sun absorbers can be installed easily.
- No pollution:No impact on air or water and no release of carbon dioxide.
- Low production cost: Reduces electricity production costs when using solar energy.
Disadvantages of solar energy:
- Rely on sunny days:Solar energy conversion processes require sunny days to be efficient.
- Blocking effect: Blocking solar rays from solar panels should be avoided.
- Large area: It requires large areas to generate large amounts of electricity.
- Maintenance required:Requires regular maintenance.
- High costs:The initial investment can be expensive.
Water energy:
Water energy is not a direct source of energy, but water falling from a high level to a low level can be used to generate energy. Hydroelectric plants are based on the potential energy of water in dams. Hydropower constitutes about 3% of global energy consumption, and this is done through the production of electricity in hydroelectric power plants.
There is also another energy source where water plays a major role, which is geothermal energy. Water in the ground turns into steam and rushes to the surface of the Earth, and this thermal energy can be used in electricity production plants.
Advantages of water energy:
- Medium to high power output:Provides large amounts of energy.
- The resulting electricity costs are low:Producing electricity from water plants is economical.
- Long plant life:Water plants operate for long periods.
- Replacing fossil fuels and not releasing carbon dioxide:It relies on hydropower without the need for fossil fuels.
- Preventing floods along the river:Contributes to regulating water levels.
- Providing water for irrigation throughout the year:Water stored in dams can be used for irrigation.
Disadvantages of water energy:
- Very high costs:Constructing water stations requires large costs.
- Collapse hazard: Collapse hazard may occur in case of poor maintenance or natural conditions.
- Effect on soil and environment:Building dams may affect the environment and change its ecosystems.
- The transformation of dry areas into water:It may affect the ecosystems of the areas surrounding the water.
Wind Energy:
Yes, when the wind blows on the wind turbine, the wind movement is converted into electrical energy. Wind fans are an ancient technology that was used in mills and then in pumping water, but currently, this technology has been developed for use in producing electrical energy on a large scale.
Advantages of wind energy:
- Establishment costs are moderate: Compared to some alternative sources of energy, establishing wind farms can be less expensive.
- The resulting electricity costs are low: Once the plant is in place, the costs of generating electricity from wind are low.
- Low environmental impact:Wind energy does not produce a lot of harmful emissions or waste.
- Does not emit carbon dioxide:It is considered clean in terms of carbon emissions.
- They can be set up quickly and the space can be expanded easily:Wind farms can be built relatively quickly and power production can be increased by adding more fans.
Disadvantages of wind energy:
- You need wind at the right speed:The optimal performance of air fans is in places where there is wind at a certain speed.
- Need backup when there is no wind:If there is little wind, storage systems or other energy sources may be needed.
- Negatively affect the beauty of the environment: Some may consider large fans an unattractive part of the landscape.
- Causing noise:Large fans may cause noise that affects nearby areas.
- Can disturb migratory birds:Propellers can pose a danger to local and migratory birds.
