Power management software company, Verdiem, is expected to release an update today of its software that monitors desktop Windows PCs and puts them in low-power mode when they're idle.
The application also gathers data on energy usage of PCs on a network so that companies can measure their energy savings and reductions of carbon emissions. A good thing, too, since a PC usually wastes about two-thirds of the energy it uses.
Renewable energy sources are flashy but tend to be more expensive than conventional power. By contrast, energy-efficiency technologies typically have a quicker payback while eliminating waste.
Verdiem's Surveyor application can pay for itself within a year by saving between $20 (£10) and $60 (£15) per PC, according to the company. For a large corporate network, that's serious money: a 10,000-PC network could mean half a million dollars (£250,000) in savings, says Matt Heinz, senior director of marketing at the company.
Energy in data centres is getting more attention because usage is going up rapidly with more web users coming online and more power-hungry servers in use.
PCs and monitors, meanwhile, are 40 per cent of IT budgets' energy usage, according to IT research and consulting firm Gartner. Servers, including cooling, take up around about 23 per cent, with the rest in communications, networking and printers.
Last year, Verdiem's software saved $6 million (£3 million) and prevented almost 38,000 metric tonnes of greenhouse gases, the company said. That's the equivalent to more than 18 million litres of gas saved, or 8,200 cars not driven for a year.
Verdiem Surveyor 5.0 has additional reporting tools and a console to centrally configure different devices. It also has better integration with Windows Vista and integrates with Intel's vPro PC management technology so that it can access machines that aren't turned on. The company has about 200 customers.
