Setting up a circuit to study renewable energy systems such as wind turbines or solar panels is easy with the Vernier Energy Sensor. Simply connect a source such as a small wind turbine or solar panel to one side and a load such as the Variable Load or a resistor on Vernier Resistor Board to the other side.

The Energy Sensor measures the current and voltage of the system. Data-collection and analysis software, such as Logger Pro or LabQest App can then calculate the power and energy output.
