       to ask if you can help with a school project. I       make shopping easier.
       have to design an invention that is powered by a
       renewable energy source.                              I think that there are a couple of things you
                                                             need to consider. Firstly, is it possible to convert

                                                             Hopefully this will help you with your project.
       I know that you know a lot about renewable
       energy, so I want to ask what you think about my      Take care,
       idea. Any suggestions you have would be great!        Bill

       Thanks,                                                    Attachment: Types of Renewable Energy

                    Types of Renewable Energy

             Wind Power                      Geothermal Energy                         Biofuel
  The wind can be used to power    Natural heat and steam in the ground     Organic mass from plants
wind turbines on wind farms which                                         and animals can be burned to
                                    can be used to generate electricity.   create electricity or used to
         generate electricity.

                         Solar Energy                                            Hydropower
       Heat from the sun can be collected using                Hydropower plants use turbines which are
26 solar panels and converted into electricity.              turned by water passing through dams or from
                                                               waves in the ocean to generate electricity.
