A new green machine from Lenovo is a response to rising energy costs around the world and to growing concern about electronics’ impacts on the environment. The new PC, officially known as the ThinkCentre A61e, is the company’s first EPEAT Gold-rated product, and surpasses the EPA’s Energy Star 4.0 criteria for computer systems with its 85% efficient power supply. It is made of 90% reusable and recyclable materials, and its packaging is also 90% recyclable. The 45-watt AMD Athlon processor that powers the computer is so energy-light that Lenovo said it can be powered by a solar panel. It is estimated that an individual owner of the ThinkCentre could save more than $20 per year in energy costs with the machine, and a company with 50 such computers in its offices would reduce its carbon footprint by more than 10 tonnes of CO2 emissions. The ThinkCentre targets energy- and environment-conscious consumers, as well as the market in developing countries like China and India, which make up 70% of Lenovo’s global sales. It will hit the market in October with an estimated retail price of $399.
