“Green World Colouring” is an app aimed at children. Basically, it is a digital version of traditional paint and color books, although in this case the issue is related to climate change. The application consists of 9 illustrations that expose the consequences of global warming and explain how renewable energy can help minimize its effects, including also some tips on how to save energy.

As can be seen in the attached pictures, each illustration includes a small explanatory text in English. The coloring tools are accessible via “Colour this page” button. In this new screen, appears a lateral menu (can be minimized) with different options:

  • “Brush/size”, to select the color and brush size or eraser.
  • “Clear”, to clean the drawing and  start from scratch.
  • “Zoom out”, that makes a zoom to all. The numbered buttons zoom the screen, which is divided into 4 quadrants.
  • “Share”, to share the image via email, Facebook or Twitter.
  • “Save”, to save the illustration.
  • “Print”, to print the drawing.
  • “Quit”, to return to the drawings gallery.

Climate change is a serious problem that will require the involvement of society to minimize as far as possible its effects. One of the main measures is education, for which the existence of suitable materials for children is necessary. This fun app for colouring with fingers or stylus performs this function, bringing this environmental problem and showing the potential of renewable energies to stop or minimize the effects of global warming and climate change. The application is particularly noted for the extensive tour that takes through the different energy sources, covering illustrations and explanations concerning the marine, geothermal, wind, biomass and solar energy. The fact that the app is only in English is not a big problem because the application is very intuitive. Furthermore, and although it is an application that currently can be downloaded for free, it has no advertising or additional purchases that can lead children to third party websites. It runs also offline, but to share the pictures via email or social networks an Internet connection is required. As a point of improvement, perhaps the tool “Zoom” is a bit limited. In this regard, it would be better a magnifying glass type tool. It would also be interesting to add new packs of illustrations (paid or free).
