Energy saving of elevators should be vigorously promoted

We know that the country is now demanding energy consumption for all kinds of energy consumption. Because our energy, one day will be used, if we have been wasting him, for energy, it is really a very great crime. So when we are saving energy, there are some problems that we have in our daily life.
For example, many elevators are running, and sometimes they don't run, but he still needs to use electricity. Because we can't stop it, if someone wants to continue to use it, it will be very inconvenient. Since the elevator is running and consuming electricity, we can install an electric ladder energy saving product for it, so that it can save energy in the process of operation.
And even if it stops running, it will save more electricity. So we feel that, in the city, both commercial and residential buildings, the higher and higher, so the elevator will be used. The elevator economizer should be popularized vigorously, because we need to know that if we carry out the elevator energy saving now, it will be a great saving for our whole resources. For our descendants, we can leave more energy, so the elevator energy conservation should be vigorously promoted and publicized.
