2.  There are records of solar collectors in the united states dating back to 1900. Around the 1900’s people started to use the suns energy to heat water. The world saw a rapid growth after 1960.

3.  Solar water heating is considered an ‘alternative renewable’ energy source because the sun is never going to run out of energy.

4.  Water is pumped through pipes in the panel. The pipes are painted black, so they get hotter when the sun shines on them. The water is pumped in at the bottom so that convection helps the flow of hot water out of the top.

5.  Energy comes to Earth from the sun in two main forms that we can use directly, heat and light. We use heat energy for solar heating and we transform the light energy into electrical energy.

6.  Some advantages are that you are not polluting the Earth, and you will save money on your electricity bill. A disadvantage is that they are very expensive to buy.

7.  Modern technology has enabled solar water heating to progress because scientists have discovered how to get solar power to heat water systems.

8.  Renewable energy career numbers rise daily all around the world.

9.  All of North QLD energy is bagasse and not solar power, the middle of Australia is solar, most of South Australia is wind power. In 2010 Australia hydro power was 63.4%, wind power was 22.9 %, solar was only 2.1% and bio gas was 11.5%.
