Alternative Sources of Energy Essay Samples and Topic Ideas
energy that the organism needs? What is energy spending? Energy spending is the amount of energy that the organism needs to carry out the activities of daily life. To know it, three components must be considered: basal metabolic expenditure, food thermogenesis and physical activity. Basal metabolic rate Basal metabolism represents the minimum amount of energy necessary to maintain the vital functions of the body when it is at rest. These activities include processes such as breathing, circulation or conservation of body temperature. In children, this value also includes the energy cost of growth. Although this value represents most of the energy expenditure, there is a variation between...

Energy balance for closed and open systems Knowing heat and energy as energy ways makes it possible for the Law on Mechanical Energy Conservation, which also includes work and external, potential and kinetic energies. As the statement tells us "although energy adopts many forms, the total amount of energy is constant, and when energy disappears in a way, it will appear simultaneously in other forms". Specific heats It is known for various circumstances that are needed from different amounts of energy to raise a degree the identical masses that belong to various substances. The specific heat is defined as the energy required to raise the temperature of a mass unit to a degree, the study...

energy that travels in the form of high -speed waves or particles. It can happen naturally or be created by man. There are two types: Non -ionizing radiation: includes radio waves, cell phones, microwave, infrared radiation and visible light Ionizing radiation: includes ultraviolet radiation, radon, X -rays and gamma rays. Since the beginning of the evolution of the human being, radioactivity has been present. That is, we support low amounts of radiation daily but, too much radiation can damage the tissues when changing the cell structure and damaging the DNA. This can also cause serious health problems, including cancer. Radiation is used in various ways such as, for example, medicine,...

We cannot ignore, that in recent years, oil demand, and therefore its price, has fallen notoriously in international markets and this, although it has had consequences in the national economy, remains the greatest income in foreign exchange and in thefiscal. On the other hand, oil, from its first exploitation, is essential in the development of education, by...
energy sources of this period can be summarized in (Escudero, 1988) Iron substitution. The use of electricity. Steam replacement for oil derivatives as energy sources. This results in many inventions such as the explosion or diesel engine that replaced the steam engine, in addition, in 1885 Benz invents the first car with NAFTA engine. The new industries were born as a result of the great inventions that took place during the period of the second industrial revolution. The expansion of electronics and computer science in industrial processes allowed automating production lines and that machines were replacing people in repetitive tasks. Two decades of accelerated advances in Internet...
