  • Hydropower is the most widely-used renewable power source.
  • Global hydroelectric installed capacity exceeding 1 000 GW
  • Accounts for almost 20% of the world's total installed power generation capacity 
  • Accounts for 50% of the global renewable power generation capacity. Jul 28, 2020, https://www.power-technology.com/

    DEFINITION: 
    • Energy is the ability to do work.
    • Work is Energy transferred.
    UNIT:
    • Joule (J)

    • Law of conservation of energy: 
    Energy cannot be created nor destroyed, but only transferred from one form to another.

    • Gravitational potential energy: 
    The energy an object possesses due to its position relative to a reference point.

    • Kinetic energy: 
    The energy an object has as a result of the object's motion.

    • Mechanical energy: 
    The sum of gravitational potential and kinetic energy at a point.

    Non-renewable energy is a source of energy that will eventually run out and that has limited supply, e.g. fossil fuels and nuclear energy.

  • Energy released when atoms’ nuclei are split apart (fission).
  • Nuclear power plants produce electricity through nuclear fission
  • The plant's core, the fuel rods and the water, is encased in a steel reactor vessel. 
  • That reactor vessel is in turn encased in a giant reinforced concrete shell, which is designed to prevent any radioactive gases from escaping.
  • In a fission reaction, a light particle (a free neutron) collides with a heavy particle (uranium or plutonium) which splits into two or three pieces. 
  • This produces insane amounts of energy in the form of both kinetic energy and electromagnetic radiation. 
  • Those new pieces include two new nuclei (byproducts), some photons (gamma rays), and some more free neutrons, which makes nuclear fission a good candidate to generate energy. 
  • The newly produced free neutrons zoom around and smack into more uranium or plutonium isotopes.
  • More energy and more free neutrons are produced.
  • Chain reaction!

    ·       In this simulation, you will be able to “see” several different forms of energy and the transfers that can occur between them. 
    ·       You are also able to work with a system where you can manipulate the energy input, observe the process of electrical energy generation and manipulate the output.  
    ·       Click on the “Energy Systems” tab. FIll in the worksheet in the next post. 
    ·       Be sure to click the “Energy Symbols” box so the different types of energy will be visible throughout the process.
