  @Ilovenerds,
  I have found ways to produce electricity and save energy which are better for the environemnt. A piece of technology called an vacuum glass with integrated solar cells can be used to insulate buildings better than common double glazing and also produce electricity from the sunlight to use in the building! This is only at research stage at the moment but as scientists we are trying to improve it and make it into an actual product that you can use in a building. It is a difficult task but it is worthing the effort as such technology can have a very positive impact in our life.
