Palace of Westminster uses enough energy to power 4,000 homes each year

New research conducted by Energy has revealed the annual energy usage of several key organisations worldwide, and just how much of their energy usage is renewable.

Network Rail’s 3.2 billion annual kWh usage could power every home in Wales for six months, or 888,888 houses for an entire year, while the relatively small Palace of Westminster’s 13.7 million kWh could power nearly 4,000 homes for an entire year. Google’s annual energy consumption could power every home in London for five months.

The team have also determined how much of this is clean energy, such as solar, water and wind. BT came out top, with a huge 95% of its energy derived from renewable sources. Apple came a close second with 92%, while Google (44%) and Facebook (35%) still have some way to go to be considered green by comparison.

Ben Wilson from Energy said: “It might surprise some to see just how much energy these companies use, especially when compared to everyday household usage.

“Identifying energy use is a key component in reducing energy bills, as businesses can often take simple measures to cut down their usage – for example, by ensuring employees switch off computers and lights at the end of the day.”
