    Question

    Which of the following is used as a clean energy source?

    1. Petroleum 
    2. Solar panel
    3. Coals
    4. Natural gas

    Hint:

    Energy from one of these is unlimited due to it's source.

    The correct answer is: Solar panel

      The solar panel is used as a clean energy source.
      Generating electricity with solar panels releases no greenhouse gases into the atmosphere. And since the sun provides more energy than we need, solar power is a very important energy source to clean energy generation.
      The running cost after installing the solar panel is very low compared to other power generation methods. No fuel is required. This means that solar energy can generate large amounts of electricity without the uncertainty and expense of securing a fuel supply.
