Global revenues from clean tech businesses--including air and water purification, advanced materials, distributed power generation, renewableenergy, and process controls, such as sensors to monitor air and water--now surpass 85 billion pounds, according to the Cleantech Venture Network, a for-profit membership group that connects venture and institutional investors with entrepreneurs.
Advantages include energy security, price stability, less demand (because less energy is lost in transmission), and fewer emissions because most distributedgeneration is renewableenergy.
