Budapest must do its part to conserve energy, and significant savings can be achieved by suspending decorative lighting, particularly during this period of critical demand, Karácsony said Thursday evening on Facebook.

He stressed that the measure would not affect street lighting.

He also urged owners of privately operated buildings with decorative lighting to follow the city’s example.

“The cityscape may be a little plainer for a while, but more energy will be available for essential purposes — and right now, nothing is more important than that,” he wrote.
