Europe would need a 2045 offshore wind capacity target of about 230GW to be in line with the Paris agreement goal of limiting temperature increase to 1.5°C by reaching a CO2-neutral electricity supply, the Ecofys consultancy says.

The estimate is the result of joint research by the energy team of Ecofys and its parent consultancy Navigant.

The energy experts in several scenario studies came to the conclusion that in order to reach a Paris-compatible electricity generation level, onshore renewable sources such as wind, solar, bio-energy, hydro and residual nuclear could provide up to 55% of the necessary capacity for 2045, while offshore would...
