The St. Louis Post-Dispatch recently published an opinion article urging Missouri to get more energy efficient. John Hickey, the director of the Missouri chapter for the Sierra Club, writes, “Missouri homeowners and businesses should embrace energy efficiency. Our opportunity is big because Missourians are wasting so much energy.” He goes on to cite that the […]

What's great about energy savings is that anyone can do it. It doesn't take a large metropolitan city to enact change, it just takes some dedication. Take Murray City, Ohio for example. Beginning in October 2010, and the 14 months that followed, Murray City enacted a block-by-block energy retrofit project that weatherized three-quarters of the […]

Compressed natural gas (CNG) vehicles are on the rise, and companies with large fleets are taking notice. In fact, a natural gas vehicle provides significant fuel cost savings, fuel efficiency, and is environmentally friendly. "Even though the price of compressed natural gas is one-third to one-half that of diesel, some companies have been reluctant to convert […]

It's a relevant question to consider: does increased energy efficiency spark more use? The so-called "rebound effect" could affect efficiency and should be examined while putting in place energy efficiency policy, according to some analysts. For example, by 2025, fuel efficiency of vehicles will be required to double. As a result, oil consumption and global […]

What can we look forward to in the New Year? When it comes to energy efficiency, natural gas is sure to become a major player. The natural gas boom is expected to continue through 2013, according to some reports. "Domestic and cleaner gas is replacing coal to power our electricity grids and replacing diesel" to […]

  Intelligent lighting control systems are gaining popularity thanks to the falling cost of light emitting diodes (LEDs) for commercial buildings. "Falling prices are triggering re-lamping projects in many existing commercial buildings. Because LEDs are particularly well-suited to digital control, many existing commercial building owners will decide to incorporate additional lighting intelligence - including photosensors, […]

Light emitting diodes (LED) technology has grown to rival the most efficient white light sources, and the benefits are great, but just how efficient are LEDs? First measure is color quality. LEDs have very high correlated color temperatures (CCTs), often above 5000K for a cold bluish light. However, warm white LEDs (2600K to 3500K) have improved […]

Leadership in Energy and Developmental Design (LEED) green building certification is growing as more and more businesses become energy efficient. Based on a survey of 7,100 LEED buildings, there are a variety of options that developers use to make buildings environmentally friendly. This includes minimizing light pollution (40.4 percent), monitoring building ventilation systems (49.2 percent), […]

It’s that time of the year where ghosts, ghouls, and goblins trick or treat in the dark of night. While you set up your haunted house this year, make sure to keep LED in mind. The latest Halloween merchandise feature LED lights that are more cost-effective and energy-saving than traditional lights. And the costs add […]
