1) The document investigates how different sizes of wind blades affect the amount of electricity produced. An experiment was conducted where 5 different sized paper wind blades were tested using a motor and multimeter.
2) The results showed that larger wind blades produced more electricity than smaller blades, supporting the hypothesis. The biggest blade of 12x6 cm produced the most electricity on average.
3) Sources of error included inconsistent blade angles and holes in some corks that held the blades. Taking more measurements could help obtain more accurate data.

1. Introduction
In today's world of climbing fuel prices, approaching the peak oil supply limit, and discussions of global warming, renewable energy is gaining more public attention and receiving more financial and legislative support. We need to learn more about the different types of renewable energy so that you can help educate your family, friends, and policymakers about ways to help our country move towards energy independence and environmental sustainability. According to a USAID report, Pakistan has the potential of producing 150,000 megawatts of wind energy, of which only the Sindh corridor can produce 40,000 megawatts.
2. Definition
Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat. Renewable energy replaces conventional fuels in four distinct areas: electricity generation, hot water/space heating, motor fuels, and rural (off-grid) energy services.
3. Types of Renewable Energy
Most Countries currently relies heavily on coal, oil, and natural gas for its energy. Fossil fuels are non-renewable, that is, they draw on finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve. In contrast, renewable energy resources such as wind and solar energy are constantly replenished and will never run out.
Most renewable energy comes either directly or indirectly from the sun. Sunlight, or solar energy, can be used directly for heating and lighting homes and other buildings, for generating electricity, and for hot water heating, solar cooling, and a variety of commercial and industrial uses.
The sun's heat also drives the winds, whose energy, is captured with wind turbines. Then, the winds and the sun's heat cause water to evaporate. When this water vapor turns into rain or snow and flows downhill into rivers or streams, its energy can be captured using hydroelectric power. Along with the rain and snow, sunlight causes plants to grow. The organic matter that makes up those plants is known as biomass. Biomass can be used to produce electricity, transportation fuels, or chemicals. The use of biomass for any of these purposes is called bioenergy.
Hydrogen also can be found in many organic compounds, as well as water. It's the most abundant element on the Earth. But it doesn't occur naturally as a gas. It's always combined with other elements, such as with oxygen to make water. Once separated from another element, hydrogen can be burned as a fuel or converted into electricity.
Not all renewable energy resources come from the sun. Geothermal energy taps the Earth's internal heat for a variety of uses, including electric power production, and the heating and cooling of buildings. And the energy of the ocean's tides come from the gravitational pull of the moon and the sun upon the Earth.
In fact, ocean energy comes from a number of sources. In add

12. Embed the sticks with rectangular hard paper (4 each) in a cork by using glue gun
13. Stick a motor of the multi meter into center of the wind blade and place it in front of an air conditioner
14. Measure the amount of electricity the wind blade produces (2 times for each wind blade)Data Processing and presentation:<br /> Amount of Electricity (mill volt)ModelTrial 1Trial 2Trial 3Averageuncertainty(2x8) 16cm253505452± 2(3x9) 27cm255576057± 2.5(4x10) 40cm219201819± 1(5x11) 55cm261595960± 0.5(6x12) 72cm273797776± 3<br />Table1. The amount of electricity (mill volt) produced with 5 different sizes of wind blades. Model 5, the biggest wind blade, produces on average 26 mill volts which is the most electricity <br />Sample Calculation:<br />Sum of the number of all 3 trials / number of trials (53 + 50 + 54) / 3 = 52.3The average amount of electricity the wind blades of model 1 produced = 52 voltmeter <br />Subtract the lowest number from the highest number /2(54 - 50) / 2 = 2The uncertainty of the wind blade model 1 is ± 2<br />Multiplication of the number of length and width of the wind blade 2 x 8 = 16The area of wind blade model 1 is 16 cm2<br />Figure1.<br />Figure1. This graph shows good result because most of the points except 2 are on the same line. It shows the constant increase of the amount of electricity as the area of wind blades increased. The outlier was not included because it is obvious that it has a mistake.<br />Conclusion and Evaluation:<br />The results showed that the wind blades that has bigger size of blade produces more amount of electricity than the wind blades that has smaller size of blade. Thus, the results support the prediction that the bigger wind blades produce more amount of electricity than smaller wind blades. The reason for this is because the area of the big blade can catch more wind than small blade so it can turn faster because of catching more wind energy and this makes more electricity.<br />The main error is that since some of the blades were not embedded in the same angle as others, so some blades did not work well. The way to solve this problem is to make sure that all the blades are embedded in the same angle. Another error is, since the cork of model 3 has some big holes, the motor was not stuck into the cork. A possible solution to this problem would be to use the cork that has no big holes in it. Temperature of the room was also possible error because air conditioners depend on how long they are turned on and how hot outside is and also how many people in the room. This may cause some small errors because temperature each time maybe is not exactly the same. This error is difficult to correct so best solution is do as many tests as possible to get accurate data. <br />http://physics.about.com/od/glossary/g/energy.htm<br />http://physics.about.com/od/glossary/g/potentialenergy.htm<br />http://answers.yahoo.com/question/index?qid=20081111181645AAt54g6<br />http://physics.about.com/od/energyworkpower/f/KineticEnergy.htm<br />www.virtualsciencefair.org/2006/wong6j2/definitions.html<br />http://www.kidzone.ws/WATER/<br />http://en.wikipedia.org/wiki/Energy_flow<br />http://en.wikipedia.org/wiki/Renewable_energy<br />http://en.wikipedia.org/wiki/Conservation_of_energy<br />
