In the middle of the night, as most of New York slept, something big and bright lit up the Manhattan skyline for just seconds-a tightly kept secret to all but a handful of people.
It was a tiny test for the huge public surprise four days later: the flipping of a switch at the Empire State Building to turn on its dancing new LED lights. They burst from the skyscraper while synchronized with R&B star Alicia Keys singing “Empire State of Mind” on nationwide radio.
The LED system has “16.7 million color possibilities, in digital combinations of ripples, sparkles, sweeps and strobes,” says Phil O’Donnell, of Burlington, Mass.-based Philips Color Kinetics that’s responsible for the system and worked with a resident lighting designer. “It’s the sum of all possibilities – a huge palette.”
The old lights came in only 10 colors.
From Manhattan and the Bronx to Staten Island and even New Jersey, “there were hundreds of thousands of people on the streets looking up, filming and videoing, clustered on street corners,” when the new lights came on, said Anthony Malkin, whose family controls the iconic Art Deco building.
In an interview with The Associated Press at his office, he glowed with pleasure describing Monday night’s inaugural light show.
Keys also sang “Girl On Fire” from her new CD.
After all, the 102-story skyscraper “has always been a symbol of what’s possible in New York, and all the dreams that can come true in this city that never sleeps,” Keys, a New York native, said before her performance, which was ready on tracks while she watched from a Manhattan studio.
Malkin and his technical team wanted to test the new lighting system with as few people noticing as possible and chose early Thanksgiving morning.
Good luck, in the middle of Manhattan, with people walking around even at 2:30 a.m.
That seemed the best moment, after most bars close and before dawn.
“We decided to do it facing west, in very short bursts between 2:30 a.m. and 3 a.m., because we knew we didn’t have a camera trained on us from there,” Malkin said.
Apparently, the secret test worked. No images of the Empire State Building alight that night appeared anywhere, as far as Malkin knows.
To stage the show, he worked with Clear Channel radio, which has 239 million monthly listeners in the United States.
The lights are part of a larger effort to modernize the 81-year-old edifice that is undergoing a more than half a billion-dollar renovation that includes making it “green.” The computerized LED system will cut energy consumption by more than half, while delivering light and vibrancy superior to the old floodlights, which have huge timpani drum-size lenses that had to be changed every so often, O’Donnell said.
They may still have nostalgic value to some who watched them light up New York City for every special occasion from Christmas to the Fourth of July.
They were part of “the grande dame of the New York skyline, now state-of-the-art, but still stately,” says Malkin, adding that the light show was “a gift we gave to the world, these lights. We don’t get paid for this.”
On a sunny Wednesday afternoon, with a spectacular view of the new World Trade Center and New York Harbor, a vacant space under reconstruction on the building’s 72nd floor was filled with the retired floodlights, sitting side by side in long lines, veterans of years of New York weather. What will be done with them is also a secret – for now.
One old light will not be discarded in favor of a 21st century novelty: a red beacon – “half the size of a Volkswagen Beetle,” as Malkin puts it – that serves as a warning signal for aircraft constantly flying over New York City.

The next few decades will see great changes in the way energy is supplied and used. In some major oil producing nations, ‘peak oil’ has already been reached, and there are increasing fears of global warming. Consequently, many countries are focusing on the switch to a low carbon economy. This transition will lead to major changes in the supply and use of electricity. [A] Firstly, there will be an increase in overall demand, as consumers switch from oil and gas to electricity to power their homes and vehicles. [B]Secondly, there will be an increase in power generation, not only in terms of how much is generated, but also how it is generated, as there is growing electricity generation from renewable sources. [C] To meet these challenges, countries are investing in Smart Grid technology. [D] This system aims to provide the electricity industry with a better understanding of power generation and demand, and to use this information to create a more efficient power network.
Smart Grid technology basically involves the application of a computer system to the electricity network. The computer system can be used to collect information about supply and demand and improve engineer’s ability to manage the system. With better information about electricity demand, the network will be able to increase the amount of electricity delivered per unit generated, leading to potential reductions in fuel needs and carbon emissions. Moreover, the computer system will assist in reducing operational and maintenance costs.
Smart Grid technology offers benefits to the consumer too. They will be able to collect real-time information on their energy use for each appliance. Varying tariffs throughout the day will give customers the incentive to use appliances at times when supply greatly exceeds demand, leading to great reductions in bills. For example, they may use their washing machines at night. Smart meters can also be connected to the internet or telephone system, allowing customers to switch appliances on or off remotely. Furthermore, if houses are fitted with the apparatus to generate their own power, appliances can be set to run directly from the on-site power source, and any excess can be sold to the grid.
With these changes comes a range of challenges. The first involves managing the supply and demand. Sources of renewable energy, such as wind, wave and solar, are notoriously unpredictable, and nuclear power, which is also set to increase as nations switch to alternative energy sources, is inflexible. With oil and gas, it is relatively simple to increase the supply of energy to match the increasing demand during peak times of the day or year. With alternative sources, this is far more difficult, and may lead to blackouts or system collapse. Potential solutions include investigating new and efficient ways to store energy and encouraging consumers to use electricity at off-peak times.
A second problem is the fact that many renewable power generation sources are located in remote areas, such as windy uplands and coastal regions, where there is currently a lack of electrical infrastructure. New infrastructures therefore must be built. Thankfully, with improved smart technology, this can be done more efficiently by reducing the reinforcement or construction costs.
Although Smart Technology is still in its infancy, pilot schemes to promote and test it are alreadyunderway. Consumers are currently testing the new smart meters which can be used in their homes to manage electricity use. There are also a number of demonstrations being planned to show how the smart technology could practically work, and trials are in place to test the new electrical infrastructure. It is likely that technology will be added in ‘layers’, starting with ‘quick win’ methods which will provide initial carbon savings, to be followed by more advanced systems at a later date. Cities are prime candidates for investment into smart energy, due to the high population density and high energy use. It is here where Smart Technology is likely to be promoted first, utilising a range of sustainable power sources, transport solutions and an infrastructure for charging electrically powered vehicles. The infrastructure is already changing fast. By the year 2050, changes in the energy supply will have transformed our homes, our roads and our behaviour.
