Answer the following question given this paragraph: 

Solar cells convert the energy in sunlight to electrical energy. They contain a material such as silicon that absorbs light energy and gives off electrons. The electrons flow and create electric current. Figure below and the animation at the URL below show how a solar cell uses light energy to produce electric current and power a light bulb. Many calculators and other devices are also powered by solar cells.


Q: What do solar cells convert the energy in sunlight into?

 Choices:

- free energy

- experimental energy

- subsequent energy

- electrical energy

A:
electrical energy
