Tendril buys Recurve for energy analytics

Energy software company Tendril has snapped up intellectual property, employees and a San Francisco office from Recurve, the startup (formerly called Sustainable Spaces) which develops and sells software to help energy auditors determine the most cost-efficient energy efficiency measures for their customers.

The top 10 trends from the year’s big smart grid show

One of the year’s largest smart grid conferences — DistribuTECH — closes today in San Antonio, Texas. It’s like the CES for utilities, power companies and the vendors that are trying to sell them stuff. Here are the top 10 trends I took away.

Today in Cleantech

Can home energy management devices reach a level of penetration that makes them a real contender for reducing household energy waste? Tendril Networks thinks so. The Boulder, Colo.-based startup is poised to move from scores of pilot projects to real-world commercial deployments in the second half of 2011, some measuring in the millions of homes, CEO Adrian Tuck told a smart grid industry audience yesterday at Greentech Media’s Networked Grid event in San Francisco. At those levels, home energy dashboards and displays could really start to deliver some of the additional benefits that separate their efficiency returns from the lower, yet more widely spread, returns seen from OPower, a startup that uses data analysis and text, email and paper-mailed efficiency tip sheets to help about 10 million utility customers around the country shave 2 to 4 percent from their energy use. One big question about both approaches to home energy efficiency, however, is how long consumers will stick with their efficiency ways before getting bored or busy and letting their efforts slip. To lock in long-term efficiency gains, some form of automation of household energy loads might be needed — but that, of course, will require a whole new level of technology embedded in the home.
