Purchase green computers using “EPEAT”
EPEAT is a system which allows buyers to make informed decisions regarding the environmental impact of computer desktops, laptops and monitors before they go ahead and purchase them.
“EPEAT evaluates electronic products in relation to 51 total environmental criteria, 23 required criteria and 28 optional criteria. To qualify for registration as an EPEAT product, the product must conform to all the required criteria.”
“Products are also ranked in EPEAT according to three tiers of environmental performance – Bronze, Silver, and Gold. All registered products must meet the required criteria, and achieve Bronze status. Manufacturers may then achieve a higher level EPEAT “rating” for products by meeting additional optional criteria, as follows”:
|

Meets all 23 required criteria |
Meets all 23 required criteria plus at least 50% of the optional |
Meets all 23 required criteria plus at least 75% of the optional |

This wind turbine is especially designed for use in the built-up environment (developed areas) on the rooftop of high buildings, the Turby, is a revolutionary new concept in the wind-turbine world/industry.
The creators description from their website
“Turby is an initiative of energy consultant and developer Dick Sidler. He works together with his son Martijn Sidler, who, like him, is a graduated electrical engineer. Turby generates a power of 2.5 kW at a wind speed of 14 m / s. Recent measurements even indicate a 10-20% higher power. Turby delivers over 3,000 kWh per year, at a suitable location -without taking into account the increase in wind turbulence – the amount of electricity that an average family uses. With a lifespan of 20 years, Turby is a sustainable investment.”
It combines the best qualities of the horizontal windturbine with the simplicity of the vertical axis windturbine. A high aerodynamic efficiency, a low sound level, no noticeable vibrations and maintenance free are its major features.
