2013-06-06 | Turning off the lights and air-conditioners for one hour is how we marked the World Environment Day.
The Earth Hour initiated by the WWF (World Wide Fund for Nature) is well known and respected all over the world. Not wasting electricity unnecessarily is a good way to prevent climate warming and to reduce CO2 emission. When natural light is not bright enough, we should turn on our office lights. When office air is stale, damp or too hot, we should turn on the air-conditioners. But some colleagues got into the habit off turning on the lights and air-conditioners as soon as they walk into the office, which is not eco-friendly at all.
To pay tribute to the World Environment Day and to alert all staff to the importance of saving electricity, a “turn off the lights and air-conditioners for one hour” campaign was carried out at ebm-papst China. Naturally, in order not to affect production and routine work, this campaign is limited to the office area.
There are 740 office lights at ebm-papst China. Each light needs 60W an hour, and so there 44.4 kW will be saved by turning off the lights. There are also 50 office air-conditioners at ebm-papst China. Each air-conditioner needs 2,300 W in input power, and so 115 kW will be saved in electricity. In total, this campaign saves us 159.4 kW. As our electricity is generated in thermal power stations, 139 kg CO2 emission will be saved.*
*For generating one kWh of electricity in China, 0.35 kg standard coal is consumed, and so 0.872 kg CO2 is emitted. Source: Baidu
