…Ever since the industrial revolution the earth’s energy needs have mainly depended on the use of the burning of fossil fuels, and why not? Fossil fuels take care of 87% of the world’s energy needs including electricity, heating, transportation, and have…

…in magical tradition relates to the mind, intellect, word, thought, and our world view. Fire equates with energy, passion, will. Water is the element of love, it represents the religious element of Wicca. Wisecraft is Earth - the practical knowledge of the Wise…

…kinetic energy levels, which increase with the orbital radius. When atoms bond together to form a solid, the electron energy levels merge into bands. In electrical conductors, these bands are continuous but in insulators and semiconductors…

…one final test that would serve as a proof that their power plant would survive a sudden energy blackout. The goal of the test was to show that the nuclear reactor 4 could be "rebooted" in the absence of any external energy sources However, there were…

…An internal-combustion engine is a heat engine that burns fuel and air inside a combustion chamber located within the engine proper. Simply stated, a heat engine is an engine that converts heat energy to mechanical energy. The internal- combustion…

…to its original shape. This shape adjustment triggers catalysis and helps to explain why enzymes only catalyse specific reactions. Below is a two-dimensional diagram to show the induced fit hypothesis. Reactions proceed because the products have less energy…

…that harness energy from sunlight to convert water and carbon dioxide into sugars that fuel the plant, while giving off oxygen. This in the long run can mean cleaner air to breath. Researchers have been puzzled by another process, photorespiration, which seems…

…the electrons energy. Break the circuit and the electrons cannot flow. Electric current is not used up because electrons are not destroyed they transfer energy as they move round the circuit. This can happen in a resistor or light bulb when thermal energy and light…

…The most important and crucial factor regarding time is that it is inelastic and non-renewable. An event cannot take place unless there is a time for it. Time and tide wait for none. We may keep in mind that time is neutral that is it is neither good nor…
