By Paul Hull Let’s join the world’s leading companies and, without waiting for government action, start developing our own clean energy guidelines. As mentioned by the Editor of this magazine on several occasions, renewable energy is receiving diligent attention from the topmost global industrial leaders. Some have already set specific goals for renewable energy use; others are changing from buying short-term (purely temporary) strategies, to longer-term strategies like Power Purchase Agreements ...... continue reading

By Dan Rafter At Washington state’s NetRiver, the power can’t go out—ever. If it does, this high-density data center located in the Seattle suburb of Lynnwood, WA, will lose its most important asset: its reputation among customers for providing reliable service. That’s why NetRiver works with manufacturers such as Eaton Electrical, manufacturers that provide the data center with the uninterruptible power supply systems—better known as UPS systems—that make sure power outages don’t happen. “If we have ca...... continue reading

Energy efficiency and solid economics have made combined heat and power (CHP) technology an attractive choice for distributed energy projects, but the number of installations in North America have yet to reflect the technology’s value and potential. Realistically, the same is true on a worldwide basis, and, according to the International Energy Agency, the increased use of CHP could reduce power sector investments by $795 billion (USD) over the next 20 years, while reducing transmission costs and retiri...... continue reading

From reciprocating engines to fuel cells to photovoltaic cells, the choices for commercial scale distributed energy (DE) technology have never looked better. Nor has the economic argument for producing energy onsite at 1 MW and higher. In fact, though manufacturers are seeing solid sales growth, they haven’t slowed their drive for innovation and efficiency. And with the recent mergers and acquisitions by some of the world’s top manufacturers and energy companies, the investment in research and developme...... continue reading

Nick Kottyan wouldn’t be able to run his two colocation data centers without the eight uninterruptible power supply systems from Mitsubishi. These UPS systems provide his clients—healthcare organizations, financial institutions, manufacturing companies, and accounting firms—with the confidence that they’ll also have access to their electronic data. With the 9900A and 9900B UPS systems from Mitsubishi, Kottyan's company, Winston-Salem, NC-based DataChambers never has to worry about losing power in its tw...... continue reading

Wind power, long used on farms for tasks such as pumping water, is finally moving to the big city. The renewable resource, which is being used to aerate ponds and generate electricity, is producing surprising savings, Return On Investment (ROI), and opportunity for a wide range of city folk—from businesses like John Deere dealers; to cities like Montpelier, ID; to schools like Sault College in Ontario, Canada, and Autry Technology Center in Enid, OK. “Wind energy is the fastest growing source of electri...... continue reading
