LEGO Renewable Energy Quiz

The LEGO Hand Generator is able to generate what type of energy?

• Mechanical

• Electrical

• Solar

• Hydro

Which is variable does NOT affect the LEGO Hand Generators efficiency?

• Changing the gearing

• The speed the handle is turned

• The length of the handle

• The amount of sun hitting the solar panels

TRUE OR FALSE: Solar panels have the ability to convert solar energy into electrical energy. They are used to

generate electricity for large utility grids, for satellites in space and in isolated locations for small

communities or single homes.

• TRUE

• FALSE

Which variable does NOT affect the efficiency of the LEGO Solar Station?

• The strength of the light source

• The size of the area exposed

• The size of the solar panel

• The amount of strength the person has

What type of energy was produced when using the LEGO Solar Station?

• Mechanical

• Hydro

• Wind

• Solar

TRUE OR FALSE: Wind turbines DO NOT have the ability to convert the wind’s kinetic energy into electrical energy. They are NOT used to generate electricity for large utility grids and in isolated locations, such as rural farms.

• TRUE
