Energy is very important in people’s daily lives. Energy has been important in human society over the past years for the handling of a variety of problems with the environment. Therefore, energy has been used in transportation, agriculture, information technology, garbage collection, and human communication. Along with the rise in innovations since the world’s industrial revolution, energy use has also continued to grow. In this paper, I will discuss how coal came into existence and how human beings in different capacities use it. Coal, which is a nonrenewable resource, takes millions of years to form and is mainly produced and stored in plants that existed hundreds of millions of years ago in swampy areas.
What is the history of human usage of this energy resource?
Since caveman coal has been used for heating. The Hopi Indians used coal in North America during the 1300s to cook and bake the pottery they made from clay. The Chinese are known in history to have used this resource in the last 3,000 years ago. The first recorded discovery that happened in the United States was in 1679 by the French explorers on the Illinois River and then legally used for commercial purposes in 1748 in Richmond Virginia
(Coal Education, 2007). People started using coal in their homes in the 1800s for heating purposes because it was too cold and it kept them warm. Also, ships and trains used coal for fuel, while factories often made steel and iron sheets using coal. In 1961 coal had become the primary fuel used in the United States to create electricity.
How is this energy resource gathered/extracted/sourced?
On the extraction, coal is being mined from the surface of the earth in two ways. That is by underground mining or by surface mining. Therefore, once extracted, it is taken directly to the heating process as well as to the industrial process or to fuel the power plants for electricity. It has to be less than 61 meters, which is 200 feet underground, for coal to be extracted through surface mining (Turgeon, 2012). Surface mining is the cheapest coal extraction method than underground mining.
How is this energy resource used by humans?
Coal has been used in the generation of electricity, cement, steel production, and also used as a liquid fuel. Thermal coal or steam coal is used mainly in generating electricity. Coking coal is used in steel production and is also known as metallurgical coal.Coal is being used in today’s world to produce electricity that is used in our homes, hospitals, schools, factories, and other places. Energy is everywhere nowadays and without electrical power, on the market, there would be a lot of problems because every sector of the economy relies on energy to ensure all of its everyday activities.
What are the comparative advantages in using this energy resource?
The coal discovery brought many benefits to humans and the rest of the world. Coal offers plenty of jobs (Coal Education, 2007). Unlike other sources of energy, coal offers many jobs in extracting coal from the earth, transporting it to the utility, burning it, And disposing of coal ash properly. It is also the cheapest source of energy and it is available in abundant supply. The use of coal offers the opportunity for continued power to a community. Many infrastructures are built specifically for using coal, providing a reasonable consumption rate for this fossil fuel. This also provides a high load factor, which by combustion gives us access to an effective and predictable level of fuel (LG, 2020).
What are the comparative drawbacks to using this energy resource?
Everything used on this earth has its benefits and some of its drawbacks. Although coal has been beneficial to humans and the world as a whole, it has its drawbacks, which harm the environment. With the increased usage of coal brings about air pollution, as well as greenhouse, and gas emission. With the increased use of coal, air pollution, greenhouse and gas emissions. There is also a strong release of toxic metals such as mercury, carbon monoxide, and sulfur dioxide. They form acid rain, which has a collision effect.
Fossil fuels are non-renewable sources of energy that take hundreds of millions of years for the earth to generate new oil, coal, and gas. Biofuels are the renewable energy sources produced from soy, corn, and other biomass. Fossil fuels take longer to produce because they are of dead animals that died a long time ago while biofuels come from animals that were recently killed. Burning biofuels often releases few carbon dioxides, greenhouse gasses into the atmosphere, while fossil fuels are the worst, mostly because they send a lot to the environment, contributing to environmental pollution. Biofuels include gasoline, biological fuel, diesel, and natural gas in the world. These are the fuels that are made from the dead biological material of recent years. Fossil fuels consist of coal, petroleum, and natural gas.
Slash and burn agriculture is the farming method that involves clearing the land by destroying as well as buying all the trees and plants on the property, then farming on that property for a short time and then going on to clear a new piece of land where to start farming again. No, this is not a sustainable form of agriculture as it has exhausted the soul. Modern forms of agriculture are always learning from this method that adding nutrients to the soil by applying fertilizers is the best way to improve soil efficiency, rather than slashing and burning.
This is also the opposite of what is expected because the percentage should likely be high. It is only because there were no plants, Which were developed there in the past in the process of producing electricity from the coal available in order to be used in the economy. There have been very few industries on the market in the past that use electricity in their manufacture of products and services and supply them to the market from selling. However, in the current situation, the demand for electricity has significantly increased with the growth of industrialization in the world and the United States. Therefore, the production of electricity using nuclear technology increases.
Ecological succession refers to the gradual process by which the ecosystems change over time and undergo development. The two types of ecological succession are primary and secondary successions. Primary succession is the series of community changes happening on the entirely new ecosystem that was previously colonized there before. The secondary succession is the series of population changes often taking place on the previously colonized but a damaged habitat. A scenario of ecological succession would be a national park suffering from a wildfire. Only small plants may colonize the burnt soil in the first year, many years have resulted in a great diversity of the tree species. While the trees before the wildfire were only one type of tree, now the landscape is dominated by deciduous forests.
Pesticides and herbicides are beneficial in farms in many ways. After countless studies, pesticides lead to cancer, ADHD, Alzheimer’s disease and birth defects. Also, they damage the nervous system, the endocrine and the reproductive system. These chemicals are applied like most in the mornings or in the evening during the cooler part of the day so that they allow the foliage to dry before the temperatures hit 85 – 90 degrees. They must take all the appropriate precautions during the application before applying the pesticides so that they can allow contamination because they have a negative effect on the human body. It is important to be concerned about the pesticides and herbicides in the food that is being consumed, and seen as the preventive measure towards eating food contaminated with the appropriate chemical handling of the chemicals can guarantee that there will be zero percent contamination from the administration of the compounds to the plants.
Over the last ten years, the United States has seen its energy sourced from coal drop (23% - 2008; 13% 2018; percent total consumption) while natural gas has increased as a source of energy (23% - 2008; 31% - 2018; percent total consumption).
The US economy has gone up with the existence of natural gas. Additionally, as economic growth increases, demand for goods and services from both the commercial and industrial sectors is also growing, which also increases the consumption of natural gas in the industries. This is because they use natural gas as fuel in the industrial area as well as the feedstock in manufacturing goods such as pharmaceuticals and fertilizers. With the growing industrialization, the need for electricity to be used in the production line is rising. The increase in demand for this power means that the production of electricity on the market rises so that the electricity generated is sufficient to be used by the increased number of industries.
