Selling Lighting by the Metric Ton of Carbon

LED lighting outfit thinks builders will be turned on by greenhouse-gas reduction more than by wattage savings

2 min read

17 August 2007—Carbon dioxide has become the latest marketing tool for manufacturers of energy-efficient lighting. Westampton, N.J.�based Lamina, a venture-backed LED lighting maker, has recently started quantifying the benefits of its technology not just in traditional terms of power usage (watts) but rather in the amount of carbon dioxide emissions produced to power an LED light versus an incandescent light. The appeal of measuring energy-efficiency in terms of CO 2 emissions is that the environmental impact of various technologies can be easily compared, says Frank M. Shinneman, president and CEO of Lamina. In addition, the growing awareness of CO 2 as a greenhouse gas makes it an accessible and intuitive unit of measurement for builders and building operators wanting to show off their green credentials.

Lamina’s recently released SoL MR16 LED, which gives off light equivalent to that of a 20-watt halogen bulb and plugs into a halogen bulb outlet, consumes only 7 watts while cutting down CO 2 emissions by a half-metric ton, on average, in its 50 000-hour lifetime (12 years in typical office use).

This photograph shows a car with the words “We Drive Solar” on the door, connected to a charging station. A windmill can be seen in the background.

The Dutch city of Utrecht is embracing vehicle-to-grid technology, an example of which is shown here—an EV connected to a bidirectional charger. The historic Rijn en Zon windmill provides a fitting background for this scene.

We Drive Solar

Hundreds of charging stations for electric vehicles dot Utrecht’s urban landscape in the Netherlands like little electric mushrooms. Unlike those you may have grown accustomed to seeing, many of these stations don’t just charge electric cars—they can also send power from vehicle batteries to the local utility grid for use by homes and businesses.

Debates over the feasibility and value of such vehicle-to-grid technology go back decades. Those arguments are not yet settled. But big automakers like Volkswagen, Nissan, and Hyundai have moved to produce the kinds of cars that can use such bidirectional chargers—alongside similar vehicle-to-home technology, whereby your car can power your house, say, during a blackout, as promoted by Ford with its new F-150 Lightning. Given the rapid uptake of electric vehicles, many people are thinking hard about how to make the best use of all that rolling battery power.
