    Sources of Energy

    Solar Energy Solar energy is light and heat energy from the sun. Solar cells convert sunlight into electrical energy. Thermal collectors convert sunlight into heat energy. Solar technologies are used in watches, calculators, water pumps, space satellites, for heating water, and supplying clean electricity to the power grid. There is enough solar radiation striking the surface of the earth to provide all of our energy needs. There are two main ways of using solar energy

  • Seasonal Energy Efficiency Ratio

    Seasonal Energy Efficiency Ratio

    "Seasonal energy efficiency ratio" (SEER), what does it mean and how does it apply to residential air conditioners. The rising cost of energy and the pollution created by production, has caused air conditioner efficiency to become an issue. Currently, the debate concerning appliance efficiency standards has revolved around the Bush Administration's proposal to weaken the standard for air conditioners from the SEER 13 standard set by the Clinton Administration to a SEER 12. The efficiency

    The Negative Effects of Nuclear Energy

    In 1950, the first commercial nuclear power plants were constructed. The public was promised a non-polluting and resourceful type of energy, but how safe was, and is, nuclear energy? Although there are less than 500 licensed nuclear power plants in the world, many nuclear accidents have already been endangering civilian lives. More serious accidents are not just likely, but inevitable (Fairchild 29). Nuclear energy may appear to be the ideal source of energy for

    Saving Electrical Energy

    “Electrical Energy Consumption” Sustainability and electricity Where does electricity come from? Most people use electricity and see it as something that is infinite and probably don’t give a second thought about its source. This is quite understandable, considering electricity looks clean; it doesn’t cause any noise pollution or direct air pollution. The fact is that most electricity is produced by burning coal, and the use of nuclear power plants. Simply stated, the more electricity

    My everyday object is my car. Can you think how the car works? First there is an energy conserved for it. And this energy is transformed from one type to another. The car needs a continuous supply of fuel which is the petrol. In the car the starter motor kicks over the engine before the oxygen using fuel can take over. This process requires the stored energy to be replaced (car battery). The energy released

    Atp as a Source of Energy for Periplasmic Permease in the Membrane Transport Systems

    The many components of cells are separated by membrane bound compartments such as periplasm, inner membrane and cytoplasm. Molecules may cross these membranes by simple or facilitated diffusion; however, active transport with ATP is required to drive the transport of large, highly charged and highly hydrophobic molecules against their concentration gradient. This energy requiring process couples ATP hydrolysis with transport proteins to bypass the impermeable nature of membranes (Wikipedia, Nov. 14, 2005, electronic communication). In
