The Connection between the Fourth Law and Energy Usage

Thursday, April 24th, 2014

Energy Crisis & Energy Alternatives

With population growth comes increased usage of energy. The energy crisis is the inability of the earth’s resources to keep pace with the population’s needs. The solution to the energy crisis is twofold – build more power stations to supply more energy, or reduce the usage of energy by building more energy-efficient devices.

There are 2 types of energy sources – non-renewable and renewable.


  • e.g. fossil fuels (coal, oil, natural gas) and nuclear energy (uranium, plutonium)
  • Takes a long time to form (e.g. millions of years)
  • Cannot be reused
  • Advantages
  • Cheap
  • Readily available
  • Efficient
  • Multipurpose (e.g. oil for cars, heating)
  • Disadvantages
  • Polluting or radioactive
  • Running out

  • e.g. biomass, solar, wind, wave, tidal, hydroelectric, geothermal
  • Takes a shorter time to form (e.g. decade or two)
  • Can be reused or is very abundant
  • Advantages
  • Won’t run out
  • Environmentally friendly
  • Disadvantages
  • Inefficient
  • Geographically selected



  • Fossil fuels began forming millions of years ago. At the time when it is believed that dinosaurs roamed the earth, forests of trees fell into swamps and were covered by silt and mud. They gradually changed into the coal, oil and natural gas that we use today.
  • The advantages of using fossil fuels are that they are readily available at the present time and are cheap. They can also be used for many purposes e.g. coal can be burnt in power stations to make electricity and also in homes for heating.
  • These fossil fuels took millions of years to form, yet humans are using them rapidly in cars, power stations and factories. They will probably run out within the next 100 years. So the disadvantages of fossil fuels are that they will run out and also that they are polluting.



  • Biomass is plant matter that is used as an energy source. For example, timber can be burnt for both cooking and heating in many homes around the world. Methane gas that is flammable can be made from rotting vegetation in methane digesters. Also alcohol made from sugar cane can be used as an environmentally-friendly alternative to petrol.
  • Solar Energy can be used in many ways. Buildings can be designed to take advantage of the sun’s warmth in the winter so that we don’t use electric heaters. Solar hot water heaters can reduce our electricity bills. Photovoltaic or solar cells can generate electricity. Solar energy is particularly useful here in Australia because of our abundance of sunlight.
  • Hydroelectric Power Stations are initially expensive to build but are cheap to run. They can be located in mountainous areas where water is stored in dams and then released to turn turbines that generate electricity.
  • Wind Energy from windmills can be used to generate electricity by turning turbines in the same way as in hydroelectric power stations. These are particularly useful in areas close to the coast where the winds are strong and continuous.
  • Wave and Tidal Power can be used to generate electricity from the rise and fall of the waves and the tides. These forms of power can only be utilised at the moment in places such as Broome where the tide rises and falls through a considerable height very rapidly.
  • Geothermal energy is energy harnessed in areas of the earth that are near volcanoes or hot springs such as in Rotorua in New Zealand. The heat can be used for domestic use. It can also be used to generate electricity by heating steam to turn turbines.
  • The advantages of using renewable energy sources are that they won’t run out and they are relatively friendly to the environment. Unfortunately, they are not as efficient in producing electricity as coal-powered power stations. Also another disadvantage of solar, wind, wave, tidal and geothermal energy sources is that they can only be used in certain areas around the world.

The connection between the First Law, the Second Law and Climate Change

Environmental Issues

  • Climate Change / Global Warming and Greenhouse Effect – The earth’s atmosphere allows a lot of sunlight to reach the earth’s surface, but reflects much of that light back into space. Some gases trap more sunlight, so that less light reflects back into space. These gases are called Greenhouse Gases, because the effect is like being in a plant glasshouse, or in a car with the windows wound up. The result is a gradual increase in earth’s temperature or Global Warming. The major greenhouse gases are water, carbon dioxide, methane, nitrous oxide, ozone and chlorofluorocarbons (CFC’s).

The main man-made causes are thought to be carbon dioxide and methane from factory, power station and car emissions, the waste products of respiration, logging, the mining of fossil fuels and the breakdown of plant matter in swamps. The long-term effects may include melting of glaciers and a rise in sea level, and a global change in climate and type of vegetation.
