Sydney lights off during Earth Hour.
What a difference an hour can make…
- According to Energy Australia, for the hour between 7.30pm and 8.30pm on 31 March 2007, there was a 10.2% reduction in electricity consumption across the Sydney CBD. This is calculated as follows: Sydney CBD temperature during Earth Hour was 19.8c. Typical energy consumption at this temperature between 7.30 and 8.30 is 228,180 KWh. Actual electricity consumption in the Sydney CBD at this time was 204,900 KWh. Energy Australia analysed data over 4 years to get the typical consumption on a Saturday night in the CBD during March and April. This takes into account daylight savings and weather.
- The energy saving during Earth Hour is equivalent to taking 48,613 cars off the road for one hour, or 200,000 standard televisions turned off for one hour. This represents a saving of 24.86 tonnes of carbon dioxide.
- Integral Energy manages the network covering Greater Western Sydney, The Blue Mountains and the Southern Highlands and the Illawarra. According to their Corporate Environment Manager, Denise Corish, their data showed that Earth Hour definitely had an effect. "Major substations in residential areas across western Sydney and also in parts of the Illawarra showed a noticeable drop in load between 7.15pm and 8.00pm, more than we would expect on a similar Saturday night. We noticed a steep decline in the first five minutes of Earth Hour, between 7.30 and 7.35pm, equivalent to the amount of electricity needed to power 6,500 homes."
