"SMART" WINDOWS COULD SAVE ENERGY'



I am going to talk about “smart” windows wich could save energy. I have chosen this article because I am interested in alternative energy sources which do not pollute the environment.

A chemical engineer at the East China University of Science and Technology has invented a window that changes its transparency to save energy. He designed a new liquid that sandwiches between two panes of window glass. So in summer, when heat just boosts cooling costs, you change its transparency blocking out some light.

Renewable energy is increasingly competitive with conventional sources of energy. In addition, thousands of jobs in both manufacturing and installation, maintenance and marketing, which contribute greatly to the economy are created.
