2. What is sustainable development? Sustainable development is a resource that aims to meet human needs at present whilst preserving the environment that we live in.

3. Sustainable development of Solar Panels, specifically their main drawback, how new designs aim to improve on this and how much they cost. Solar Panels These solar panels are conventional panels that you and I would have on our house in order to help with the electricity bills. These solar panels are mass producing energy probably for a small town.

4. Draw Backs For a solar panel to work at 100% of its fully working function then the sun must be at a right angle to the flat surface of the solar panel. The sun must be at the specific angle for the solar panel to work at its best.

5. To get 100% from the panels of semiconductor fitted with concentrating lenses and motors to move it around. New Designs This solar panel is able to move with the sun, by following its rays, in order to catch the most possible sun light from the sun.

6. Students at the University of Illinois have now come up with self-assembling spherical solar cells. Origami Solar Cells In these images, three thin films of silicon fold up into 3-D shapes under the force of surface tension as water droplets placed in their centres evaporate. when the water droplets are large, and the images below it show a time progression as the water droplets shrinks.

7. The Cost? Unfortunately these spheres have not been fully tested yet nor put into production. The only indication is that they will be more than the present solar panel. Student – 463365 Lecturer - C Nguyen
