Here's what it says on the greenbid.cc website:

     Green technology, or cleantech, investing seeks sustainable investments in environmentally friendly companies that work to improve their operations, performance, productivity and efficiency, while lowering their costs, energy consumption, inputs, waste or pollution. Clean technologies can lower a company's environmental impact and may provide improvements in resource efficiency and productivity. When a company operates with less energy and materials, or produces less waste, the result can create more economic value for the company and its shareholders.      Cleantech is currently clustered in six industry sectors: energy, water and waste water, advanced materials, energy efficiency and manufacturing, transportation and agriculture. The largest of these sectors is energy and can range from biodiesel, clean coal and fuel cells, to wind and solar energy.      Investing in cleantech does not mean investors have to sacrifice returns. Instead, the potential for cleantech is broad and likely to expand because it can add to both a company's bottom line and bring greenbacks to an investor's portfolio.
