-- Hub firm rises to challenge of green computing (Boston Globe)Labandibar [the entrepreneur] believes the machines emerging from her Southie shop today can compete with anything the big companies can offer. In addition, the green machines from Dell and HP are mainly targeted at high-end business customers who face soaring energy costs because of the high numbers of machines they operate; the companies don't yet offer energy-saving technologies across their entire product range. By contrast, Tech Networks mainly sells its efficient machines to smaller firms.
Apparently, a big part of the savings comes from higher-efficiency power supplies, for which the firm gets $5 rebates from the local power company ($10 for servers).
The computers also are configured by default with aggressive power-saving settings (e.g. going to sleep).
