Economics on the matai islands

Some people money makes the world go round and basically it does, with the markets also supply and demand. Supply and demand control all companys because when demand goes down so does there need for supply. Here is a diagram showing how supply and demand work.

As you can see the supply and demand affect the economy and the price. Also the consumer like you or me depends on how well the product will sell. If the product isn't something we need and it's too expensive we will just wait until the price comes down.

Building a eco house with eco materials and energy

Eco housing is the thing of the future here is some info of what you can do to help save the earth.

  • How solar heating works is solar radiation is absorbed and converted into heat through a series of toughend glass cleared tubes.
  • Another way of heating is a ground source heat pump which pumps through air that slowly gets hotter as it is pushed through the pipe then gets pushed out a heat pump into your house.
  • Photovaltaics is advanced technology that is similar to solar panels but instead of turning it into heat it turns it into electricity. Cool right.
  • Collecting rain water into a tank and using it for gardening and household use. You may think it is stupid but you can put a filter on it so it is clean.
  • Double glazing and insulation do the same by keeping the heat in and keeping your power bill down.
