Electricity Science Fair Project

Hydropower vs Wind Power

Hydropower vs Wind Power | Science Fair Projects | STEM Projects
Are you curious about which type of renewable energy is more efficient? Find out by building a dam and a wind turbine and measuring the power they generate.


The hypothesis is that hydro power generation is more efficient than wind power generation.

Method & Materials

You will build a dam across a river and use a generator to convert the potential and kinetic energy of the water into electric power. You will also build a wind turbine and measure the voltage, ampere and calculate the power.
You will need a 15W fan, a 15W water pump, a dynamo fitted with blades, a dynamo fitted with water wheel, a pail, a large basin, tap water, a knife, a 5.25ohm resistor, an ammeter, and a voltmeter.


The results showed that hydropower generation produced electric power more efficiently than wind power. This proves that the hypothesis is true.

Why do this project?

This science project is interesting because it allows students to compare two renewable energy sources and measure the efficiency of each.

Also Consider

Experiment variations include comparing the viability of other renewable sources of energy like solar power or wave power, and varying the height of the pail or the distance of the turbine blade from the fan.
