LED


For the second part of this series – the first one was on heating – we are having a look at electricity consumption of households and the various ways we can decrease it. This will enable you to have lower energy bills – always a good thing with the hard […]

Towards sustainability, reloaded : electricity


Incandescent light bulbs are a relic of the past, a vastly inefficient past. Modern alternatives like CFLs and LEDs consume five to ten times less energy. For these reasons, the European Union or Australia have already phased them out. More countries will be doing the same, namingly the United States […]

China & the USA to ban incandescent light bulbs


To GOOD : ” One German physicist, Harald Haas, has come up with a solution he calls “data through illumination” (…) by sending data through an LED lightbulb that varies in intensity faster than the human eye can follow.” ” It’s the same idea behind infrared remote controls, but far […]

The city of Barcelona and Spanish utility Endesa have been installing smart LED lightning systems that automatically switch themselves off when no one is around. This enables the city to cut by 30 percent its electricity consumption. I really would like this idea to spread across Europe and even the […]

Barcelona’s amazing smart lightning idea


The US Department of Energy released last week an interesting study on how LED lightning could enable America to save $120 billion (88 billion euros) over the next 20 years. To Ecogeek : ” The cumulative savings of widespread adoption of this technology over the next 20 years would be […]

The huge potential of LED lightning


CFLs consume up to five time less energy than traditional incandescent and halogen bulbs. This convinced several countries including the European Union and India to increasingly use them. Now LEDs are slowly reaching the markets. Consuming up to half the energy of CFLs they come in all shapes and colors. […]

Think CFLs are great ? Read on…

The European Union decided last week to ban all incandescent light bulbs by 2010. This occurs as Australia, Cuba and the Philippines did the same last year. This is important as the EU and its 27 members accounts for nearly half a billion inhabitants. This law is due to cut […]
