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.
