Saving time and energy
The last weekend of October marks the clocks moving backward by one hour. On Sunday morning, 3 a.m. will become 2 a.m. in Hungary (and across the Central European Time zone), which can lead to considerable electrical energy savings, according to MAVIR, the Hungarian transmission system operator.
MAVIR says using daylight saving time (DST) saves the amount of electrical energy consumed annually by a mid-sized Hungarian city, according to a press release sent to the Budapest Business Journal.
Hungary has been using DST since 1980 and, according to MAVIRʼs calculations, the estimated energy saving has been 4000 GWh, which equal five weeksʼ average consumption in the country. DST not only saves money, but also protects the environment, as less energy means fewer CO2 emissions, the operator adds.
A comparison of energy consumption before and after the DST change on March 26 shows that the energy saving has been above 9 GWh. On the whole, the saving is 1-2% daily, given similar conditions, such as the weather, MAVIR says.
