Christmas Lights: The Champs-Elysees To Compensate For Solar Energy

Like every year, the Champs Elysees street lits up for the holiday season: their Christmas lighting has been unveiled on November 23 and will be decorating the famous avenue until January 11. The start was given by the sponsor of the event, Audrey Tautou.

However, promises the mayor of Paris, these lights will be "bolder and more environmentally friendly", with reduced power consumption by almost one third in one year, (after the Eiffel Tower, where the renovation of the first floor is taking place to improve the energy performance by 30%), another Parisian symbol turns green.

The project chosen (among the 27 presented), was created by Koert Vermeulen and Marcos Vinals Bassols of the Belgian ACT Lighting Design, in collaboration with ASP Blue Square.

It consists of installing about 200 trees of three rings of different sizes (between 3.12 and 3.84 m in diameter), lighting up every tree without touching them. Each ring is equipped with RGB LED (Red Green Blue) lighting up the tree at 360 ° and being reflected in "disk mirror" a shape clinging to the branches. A programmable RGB LED device, controlling each ring separately, will be varied color, intensity and rhythm.

What about power consumption in a month and a half? The City indicates that it will sharply lowered down to 31,000 kWh during the year 2011, against 50,000 between 2007 and 2010 kWh and 480,000 kWh by 2006, 15 times less in half a decade.

The equivalent of 40 days of photovoltaic Pyrenean

For the first time, this consumption, which is equivalent to that of eight families of four people living in an apartment in Paris, will be fully offset by renewable energy. It will be supplied by a solar power plant, Themis, in the Pyrenees-Orientales, where Soitec has installed 26 solar trackers. They occur in 40 days and 31,000 kWh required for illumination of the Champs-Elysées. These trackers, which use photovoltaic technology concentration, will produce 280 MWh / year.

The total cost of these 2011 lights is going to be around 4 million euros, of which 220,000 are paid by the city while the rest is being borne by the partners and the Committee on the Champs Elysees.
