It’s clear that the drive for more renewable energy sources to power our everyday lives has never been stronger. However, powering a capital, such as London, is easier said than done. The city would need nearly 1,500 wind turbines to meet demand, according to new research from Uswitch.com, the comparison and switching service.
Uswitch.com has analysed how much wind energy is needed to power European cities and how much space would be required for these wind turbines.
So which European cities need the most wind turbines to fully power them and how much offshore space does that really take up?
Moscow in Russia, which has an area of 2,511 square km and a population of over 12 million, would need 3,781 offshore wind turbines to power the city. This is the most out of all of the European capitals analysed and would take up 7,409 square km in order to power each area.
With an offshore wind turbine having the average rotor diameter of 148 metres, the large area needed to home the number of turbines to power European cities is no surprise. Even Reykjavik, Iceland, which has a population of just 115,000 people, and an area of 275 square km, would need 48 offshore wind turbines to power the capital non-stop.
To comprehend just how much energy wind turbines create, they generate 4,510,000 watts per hour, which is equivalent to 1,253 watts per second. This means it would take just 0.03 seconds of energy to power your Christmas lights and 6.71 seconds to cook the turkey on Christmas Day.
Sarah Broomfield, energy expert at Uswitch.com comments: “To be able to deliver clean, renewable energy to every major city around the world will be an important part in helping to reduce carbon emissions. Wind farms don’t emit greenhouse gases, therefore energy sourced from wind turbines is a key aspect to combating climate change. That’s why Boris Johnson’s 10-point Green Plan to quadruple offshore wind turbines by 2030 and power every UK home from them is a step in the right direction to reducing, and hopefully reversing, some aspects of global warming.”
