As part of its first major retrofit in 30 years, two custom-designed wind turbines have started generating power for the Eiffel Tower. Located above the World Heritage Site's second level, about 400 feet off the ground, the sculptural wind turbines are now producing 10,000 kWh of electricity annually, equivalent to the power used by the commercial areas of the Eiffel Tower's first floor. The vertical axis turbines, which are capable of harnessing wind from any direction, were also given a custom paint job to further incorporate them into the iconic monument's 1,000-foot frame. At the same time they bring the image of the 1889 tower firmly into the 21st Century.
[...]In addition to the wind turbines, the renovation includes energy efficient LED lighting, high-performance heat pumps, a rainwater recovery system, and 10 square meters of rooftop solar panels on the visitor pavilion.
There was no required renewable energy target for the Eiffel Tower's facelift, but the project developers see it as a major landmark in Paris' climate plan. The city's plan(PDF) aims for a 25 percent reduction in greenhouse gas emissions, a 25 percent drop in energy consumption, and for 25 percent of energy to come from renewable energy sources by 2020.

Indeed, that's a paltry amount of power. I don't know what "the commercial areas of the Eiffel Tower's first floor" includes but I suppose it's just a handful of light fixtures.

There's one very expensive restaurant and some visitor stuff.
Arguably, the first floor is open about 14 hours a day on average, so the 10MWh/yr average closer to 2kW. That's a couple hundred LED lightbulbs. I don't think they counted the elevators in the "first floor"...

To put it in perspective, my small 2kW residential solar system generates about 3200kWh per year. Our local council have installed 17.5kW worth of PV on the library and 30kW on the admin office generating a combined 78000kWh/year.
10,000kWh is pitiful for a commercial site and national monument.

You don't normally want to change the look of a national monument much.
Nobody in their right mind is going to cover the Great Pyramids in Egypt with tons of solar panels even if that would generate a lot of solar energy.
Same goes for this. This is just some feel-good gimmick/symbolic gesture. If you want real wind power it'll be generated at a wind farm not a national monument.

Given that some archeologists think that they were covered by white stone tiles and even a golden tip, it's even possible that they would look a bit more faithful to their aspect in ancient times.

It may be pitiful compared to the power consumption of the site, but it is pretty good for a site that can't be disfigured for historical reasons.
No, you are mistaken. I've always had this sig.

Well yeah, there is that.
You can't even notice these vertical turbines from the ground, but simply converting to LED lighting everywhere would probably saved more power than they will ever generate. The flood lights they use at night are enormous. Perhaps no LEDs that big yet.

I agree, I'd say they did a pretty good job of "unobtrusive modernization". In fact I really like the looks of the turbine, but I miss some Tesla-coils throwing sparks all around the place.

There is no "can't" about it - there is nothing that the greenwash brigade would not stop at to ram their schemes down everyone's throats, and as far as they are concerned the more in-your-face it is the better. They would recycle the dead sea scrolls if they could get their hands on them.
As someone else said, the power being produced is piffling , not much more than 1 kW. There is a major restaurant and other facilities on that level and 1 kW would hardly keep a grill pan going. It is a publicity stunt.
