  • Chemical Energy is energy stored in the bonds of atoms and molecules. It is the energy that holds these particles together. Biomass, petroleum, natural gas, and propane are examples of stored chemical energy. \nDuring photosynthesis, sunlight gives plants the energy they need to build complex chemical compounds. When these compounds are later broken down, the stored chemical energy is released as heat, light, motion and sound. \n\nStored Mechanical Energy is energy stored in objects by the application of a force. Compressed springs and stretched rubber bands are examples of stored mechanical energy. \n\nNuclear Energy is energy stored in the nucleus of an atom the energy that holds the nucleus together. The energy can be released when the nuclei are combined or split apart. Nuclear power plants split the nuclei of uranium atoms in a process called fission. The sun combines the nuclei of hydrogen atoms into helium atoms in a process called fusion. In both fission and fusion, mass is converted into energy, according to Einstein's Theory, E = mc2 \n\nGravitational Energy is the energy of position or place. A rock resting at the top of a hill contains gravitational potential energy. Hydropower, such as water in a reservoir behind a dam, is an example of gravitational potential energy. \n\n

  • Electrical Energy is the movement of electrons. Everything is made of tiny particles called atoms. Atoms are made of even smaller particles called electrons, protons, and neutrons. Applying a force can make some of the electrons move. Electrons moving through a wire are called electricity. Lightning is another example of electrical energy. \n\nRadiant Energy is electromagnetic energy that travels in transverse waves. Radiant energy includes visible light, x-rays, gamma rays and radio waves. Light is one type of radiant energy. Solar energy is an example of radiant energy. \n\nThermal Energy, or heat, is the internal energy in substances the vibration and movement of atoms and molecules within substances. The faster molecules and atoms vibrate and move within substances, the more energy they possess and the hotter they become. Geothermal energy is an example of thermal energy. \n\nMotion Energy is the movement of objects and substances from one place to another. Objects and substances move when a force is applied according to Newton's Laws of Motion. Wind is an example of motion energy. \n\nSound Energy is the movement of energy through substances in longitudinal (compression/rarefaction) waves. Sound is produced when a force causes an object or substance to vibrate; the energy is transferred through the substance in a wave. \n

  • FOSSIL FUELS
  • Fossil fuels or mineral fuels are fuels formedby natural resources such as anaerobicdecomposition of buried dead organisms. Theage of the organisms and their resulting fossilfuels is typically millions of years. These fuelscontain high percentage of carbon andhydrocarbons. Source: http://en.wikipedia.org/wiki/Fossil_fuel

  • The Exxon Valdez oil spill was not a large one in relation to the world s biggest oilspills, but it was a costly one due to the remote location of Prince William Sound(accessible only by helicopter and boat).On March 24, 1989, 10.8 million gallons of oil was spilled when the ship s master,Joseph Hazelwood, left the controls and the ship crashed into a Reef.The cleanup cost Exxon $2.5 billion.

  • Piper Alpha the worlds worst off-shore oil disaster. At one time, this oil rig was the world s single largest oil producer, spewing out 317,000 barrels of oil per day. Piper Alpha was a North Sea oil production platform operated by Occidental Petroleum. On July 6, 1988, as part of routine maintenance, technicians removed and checked safety valves which were essential in preventing dangerous build-up of liquid gas. There were 100 identical safety valves which were checked. Unfortunately, the technicians made a mistake and forgot to replace one of them. At 10 PM that same night, a technician pressed a start button for the liquid gas pumps and the world s most expensive oil rig accident was set in motion. Within 2 hours, the 300 foot platform was engulfed in flames. It eventually collapsed, killing 167 workers and resulting in $3.4 Billion in damages.Source: http://www.ssqq.com/archive/disasters.htm
  • GAS
  • PEAT
  • burning fossil fuels increases carbondioxide in the atmosphere whichi n c re a s e s t h e G R E E N H O U S EE F F E C T, c a u s i n g G L O B A LWARMING.
  • Some fossil fuels contain SULPHURand when they burn this becomesSULPHUR DIOXIDE, a poisonousgas which reacts with water in theatmosphere to form SULPHURICACID or ACID RAIN.
  • Don’t despair,there is good news also
  • FOSSIL FUELS are running out!!!!!
