So what is a green job? Well green jobs are architects and engineers that build buildings, design buildings that operate at extremely low energy use. They are people that design, manufacture, and install devices in buildings ranging from high-tech windows to lighting to sensors and controls and electronics. It means looking at radically new industrial processes which simply replace previous kinds of industrial manufacturing with sophisticated bionumetics and nanotech approaches, to cutting down the material intensity and energy intensity of production, this is the kind of thing you need to do to stay competitive in the modern world.
