1. Renewable Energy Iulian Balan, Derek Suelzle Technology Access Foundation Academy

2. Need for the Study Pollution is a major cause of global warming -Causes asthma -Animals become extinct -Glaciers melt and cause floods Non-renewable energy drains the earth of its natural resources and cause pollution -Oil spills pollute oceans -Coal releases carbon dioxide which affects the environment in a negative way

3. Driving Question and Hypothesis How can one produce renewable energy that functions efficiently for everyone’s daily use? The design would use easy to get materials, produce a small amount of energy that could be increased and there would be a way to reuse that energy.

4. Materials and Methods - Hydroelectric and wind power design - Water powered battery design Materials: 1.Zinc N ails $3.00 2. Copper Wire $7.00 per 100 ft 3. Water/Vinegar $11.00 per gallon 4. Cup $7.00 for 100 cups 5. Voltage Meter $22.00

5. How it works Batteries are made of two different metals suspended in an acidic solution. With the water powered battery, the two metals are zinc and copper. The nail is coated with zinc which prevents rust and the acid comes from the water inside the cell. When all are combined in a circuit an energy source is created.

6. Results The prototype produced a small amount of energy and when the amount of cells increased the amount of energy produced also increased. The supplies were cheap and easy to get.

7. Graphs or Images Section Table Amount of cupsVoltage 1 Cell/cup0.021 2 Cells/cups0.039 3 Cells/cups0.057

8. Analysis and Conclusion According to the data table the prototype produced more energy when more cups/cells were added to the circuit. Since the prototype uses water, the water could be reused instead of gathering new resources.

9. Evaluation and Future Implications -Next time we could build both designs to test if one would produce more energy than the other -We could have changed up the wires and or liquid to test for more voltage such as using Vinegar because it has a greater acidity level than water

11. Abstract This abstract explains the importance of renewable energy as well as how people can use this renewable energy in their everyday life without harming the environment. Renewable energy is very useful in today’s society not only because it’s renewable but because it is clean energy and does not deprive earth of its natural resources. The experiment has to do with making a prototype that can produce energy as well as not harm animals. The prototype requires little space but is efficient in producing energy for regular household items. This is an important experiment because animals including fish and birds get harmed by wind and water turbines, also the renewable energy sources that are being used now take up huge amounts of land and water areas and solar panels for households cost too much and require the sun for power. This land could be used for more than just giant turbines; this land could be used for stores and houses as well as useful industries. The outcome of the experiment will produce an efficient energy source that could be placed anywhere including underground as well as produce power and not harm any living creatures.
