Navigant Research projects that revenues from energy harvesting (EH) technologies will come in at about $268 million globally this year and will reach nearly $375 million in 2020, a compound annual growth rate (CAGR) of 4.9 percent. A recent report from the group analyzed the market for photovoltaic (PV), piezoelectric, electromagnetic, and thermoelectric energy harvesting technologies as employed in industrial and consumer products “that are untethered or need to become disconnected from the electrical outlet.”
Conventionally, such devices are powered by batteries, but energy harvesting represents an option with potentially lower costs, lower maintenance, greater convenience, and lower environmental impact. Read more
This surge in natural gas output has significantly increased the need for specialized chemical tankers that can move product between the U.S. and Asia, where demand is strongest. Long manufacturing lead times present a challenge for shippers that is difficult to skirt around. Read more
Weather-related power outages cost the nation between $18 billion and $33 billion annually, according to the U.S. Department of Energy. So it isn’t surprising that many heavy energy users are taking a hard look at the microgrid model. Read more
Half of the people in the world, 3.6 billion, now live in cities, according to a report from management-consulting firm McKinsey & Company. That’s more than at any other time in human history, both in raw numbers and in proportion. The firm projects that by 2030, that percentage will rise to 60 percent, or 5 billion people.
This unprecedented growth presents a challenge in environmental management. Sustainable urban growth, says McKinsey, will “depend upon investment in infrastructure that reduces emissions, waste production and water use, as the way we build and renovate our cities will determine their ecological sustainability for decades to come.”
The world’s cities today are “data rich” but “information poor,” says a paper from research firm Ovum. “While cities are collecting more raw data than ever before,” the firm asserts, “they are encountering difficulties in breaking down silos and converting the data into usable, actionable, accurate information.” Ovum believes that “smart cities technologies” can help spur a needed transformation.

In rising numbers, utilities are looking to smart-grid technologies to improve efficiency, reduce costs, and help in the recovery from disasters such as storms and blackouts, according to Ed Kennedy, CEO of Tollgrade. But success in implementation hinges on a solid understanding of what smart-grid systems can and cannot do. Read more
