An Environmental Protection Agency-commissioned survey finds energy intensity in cement production dropped 13 percent from 1997–2007. Duke University researchers compared producer-collected energy usage data against Department of Commerce figures, confirming a 1 percent-plus improvement trend per year to factor into EPA’s cement industry energy curve. The power savings equate to a reduction of almost 1.5 million metric tons of energy-related carbon.

The developer of ThermaPaver, a heat exchanger nested beneath ground- or pedestal-mounted concrete paving stones, is one of six University of New Hampshire Green Launching Pad grant recipients. The technology can transfer pavers’ solar-generated heat to a home water tank or swimming pool; in the winter, the process can be reversed to melt snow and ice. ThermaPaver can also source heat from or convey it to geothermal systems.
