Ever since the Industrial Revolution, we have been burning fossil fuels to create energy (History, n.d.). Traditionally, coal is burned and heat is created, that heat then causes water in pipes to turn into steam. The steam is kept under high pressure, the pressure then drives the steam over the blades of a steam turbine, causing it to spin. This converts the heat energy into mechanical energy which is then converted into electrical energy using a generator (Union of Concerned Scientists, n.d.). The problem with using coal and other fossil fuels is the fact that they are non-renewable and can take over five-million years to form. Due to this, it is estimated that we will exhaust our supply of non-renewable resources in the next 50 – 100 years (Ecotricity, n.d.). By using matter/antimatter reactors, also called positron reactors, to create energy, the problem will be solved as there is an abundant supply of antimatter in the universe (Fool Moon, n.d.).
Antimatter is a material composed of antiparticles, which have the same mass as particles of “ordinary” matter, but have opposite charges and other properties such as spin and lepton number. An example of this can be seen when examining the charge of the particles. An electron has a charge of negative one; a positron (antielectron) has a charge of positive one. The same can be seen when comparing the charge of a proton and an antiproton (CERN, n.d.). An encounter between particles and antiparticles leads to the annihilation of both particles, creating a huge release of heat in the form of gamma rays, which can then be converted into energy. This is due to the fact that the spin of particles and antiparticles is opposite, so when the two meet, they create a spin of zero. The only thi...

Overall gamma rays contribute greatly to our health and our understanding of our universe. Its high level of energy leads to many medical benefits when used wisely and carefully, and even though it can cause many dangerous and harmful reactions, we have developed a strong understanding of the photon so that we know how to effectively and efficiently use it without causing harm. Our understanding of the photon has led to curing medical conditions, understanding specific characteristics and fields of our universe and creating a financially efficient and safe system of economic production.
Semantically fossil fuels are a renewable source of energy, however given that it takes millions of years for the organic materials to be broken down and converted, it is wholly unrealistic to consider them as renewable. As the demand for fossil fuels increases and source diminish faster than they are replentished, the United States must work towards a renewable energy independent state using truly renable sources, both technically and in practice. With changes in the home, as consumers in buying goods and with alternative fuel sources backed by public trust and governmental involvement, the United States could drastically lessen its dependence on fossil fuels, foreign and domestic.

From the home to factories, families and industries are reliant on the use of nonrenewable fossil fuels to feed the needs of the everyday human. Fossil fuels are the main source of energy over clean, renewable sources such as the use of wind, solar energy, and water to power our homes, schools, and industries. In fact, about 85% of energy use comes from fossils fuels. The main reason being that using fossil fuels is cheaper than wind and solar energy. “For nearly two centuries, fossil fuels have been the cheapest source of energy” and widely abundant (Marburger, A global framework: international aspects of climate change). However, overtime fossil fuels will disappear due to the lack of time to replenish itself with the human races rapid use of it. Despite its current status of availability, there are many controversial issue in using fossil fuels; the most prominent issue being that it is the cause of rapid climate

Antimatter is exactly what the name suggests. It is the opposite of matter in which the charges associated with electrons and protons are switched. This means a proton and antiproton are attracted to each other. When they collide pane energy is produced in the form of three pions and four gamma rays.
The use of nuclear processes (decay, fusion and fission) to generate energy in the form of useful heat and electricity. Fission reactions are currently further developed than other methods of producing nuclear energy; however it is believed that once nuclear fusion reactors are successfully developed to the extent to which they can function and produce substantial energy, they can be the leading form of energy production as they are substantially safer, more convenient and more efficient.
From a very young age, I have enjoyed reading a wide spectrum of topics. However, during high school, I had become preoccupied with physics during my studies and readings, and so I began to focus my attention upon the materials that further shed light on the science. The more I read, the more I became intrigued with the interrelations between matter, energy, and time and space motion illustrated through the science. Therefore, motivated to become one of Saudi Arabia’ few female physicists, upon graduating from high school I opted to major in the science that captivated me like no other....
The Industrial Revolution sparked a need for large sources of energy. Human and animal labor could not provide the power necessary to power industrial machinery, railroads, and ships. The steam engine and later the internal combustion engine provided the bulk of the energy required by the industrial age. Today most nations are still heavily reliant on energy that comes from combustion. Usually coal, petrolium, and natural gas are used. Some hydroelectric, wind power, and nuclear fission sources are used, but in the US they accounted for less than 20% of the total energy consumption in 1997 (1). Many experts are worried that natural resources such as coal and petrolium are being depleted faster than they are being replenished, which could result in an energy crisis. Nuclear fission produces highly radioactive waste that is expensive to dispose of properly. Nuclear fusion reactors would produce much less radioactive waste and would be more efficient than nuclear fission, but to date there have been no nuclear fusion reactors that have generated usable energy output. Why is fusion power, which could be very beneficial, so hard to come by?
As one of the greatest alternatives to fossil fuels, an important advantage of nuclear energy is the significantly lower emission rate of CO2 in comparison to plants which use coal and natural gas.2 Nuclear power is not reliant on fossil fuels and therefore producing energy by this method reduces pollution and the contribution to climate change. However, whilst the actual process of generating energy releases few emissions, uranium must be mined and purified and in the past this has not always been an environmentally clean process.2 Ultimately, uranium will one day run out, but nuclear reactors are versatile and may also run on Thorium. Despite being finite, this would allow nuclear power stations to function for a longer period of time.
Fossil fuels are energy that is in the form of coal, oil, or natural gas that comes from organisms from millions of years ago. The cycle to create fossil fuels takes millions of years to form and is therefore considered a nonrenewable resource of energy. Fossil fuels have been the primary source of energy for man ever since the age of machines, but one of “the main problem[s] with fossil fuels is that there is a limited amount of them” (Problem with Fossil Fuel). As countries become more developed, like the United States, they too will become more thirsty and dependent for fossil fuels. “In 2004, America spent approximately $270 billion to fufill its oil need.” and “90% of all transportation is fueled by oil” (Nakaya 10). With the global rate of fossil fuels going up it is inevitable that they are going to run out, forcing countries to choose an alternative energy source. The other huge problem with dependence on fossil fuels is the effect that the emissions have on the climate. Fossil fuels are made of carbon chains and in order for the reaction...
The world that we live into today affords us the expectation that the flip a switch will turn the lights on. As populations increase and developing nations undergo dramatic economic growth, this energy demand will only continue to grow. The International Energy Agency (IEA) believes that “the world’s energy needs could be 50% higher in 2030 than they are today” (ElBaradei). Given this projected growth, it is necessary for world leaders must take action to secure the energy supply. Meaning that world leaders need to start seriously considering an alternative to non-renewable energy sources. “In 2012, the United States generated about 4,054 billion kilowatt-hours of electricity. About 68% of the electricity generated was from fossil fuel (coal, natural gas, and petroleum), with 37% attributed from coal” (U.S. Energy Information Administration). The fossil fuels that are used to supply over half of our country’s energy are in finite supply and are increasing in price to astronomical heights.
