ESSAY ON ALTERNATIVE SOURCES OF ENERGY The law of conservation says that energy is neither created nor destroyed. When we use energy‚ it doesn’t disappear. We change it from one form of energy into another. A car engine burns gasoline‚ converting the chemical energy in gasoline into mechanical energy. Solar cells change radiant energy into electrical energy. Energy changes form‚ but the total amount of energy in the universe stays the same. Scientists at the Department of Energy think they have

Nuclear power is one of the most controversial energy sources in Canada and also throughout the world and is being talked about very frequently lately as to whether or not it is a safe alternative to other forms of energy such as coal or oil. In my opinion‚ energy from uranium (nuclear power) is a reasonable alternative to other forms of energy that come from non-renewable resources that are rapidly depleting. In the following essay I will enforce my opinion in the subject and attempt to convince

Nuclear Chemistry Nuclear science is the study of sub-atomic particles and their function in various subjects. A nucleon is the collective name for the two components of the atomic nucleus: the neutron and the proton. Isotopes are any of the different forms of an element each having different mass numbers‚ which give the total number of nucleons. The major fundamentals of nuclear chemistry include radioactive decay‚ the nature of fission and fusion‚ and mass defect. The decomposition of the

Moreover Radars‚ spacecrafts‚ interstellar probes and other advanced communication devices require much larger power than that can be met by conventional energy sources. The solution to long term energy source is the nuclear powered batteries which have a life span of few decades and can pack in energy densities thousands of time greater than conventional battery sources. Hence‚ there is an urgent need to harvest enormous amount of energy released naturally by the
