Most wind/solar infrastructure has historically not been monitored or had any concrete security measures in place; it is only in the aftermath of the Nord stream attack that companies are starting to monitor offshore wind farms using, for example, remote monitoring CCTV and drones. <ref>{{Cite news |last=Gronholt pedersen |first=Jacob |last2=Kate |first2=Abnett |date=26 October 2023 |title=Europe's wind power goal hits new snag: security |url=https://www.reuters.com/business/energy/europes-wind-power-goal-hits-new-snag-security-2023-10-26/ |url-status=live |work=Reuters}}</ref> Given the expected increase in number and geographical distribution of windfarms in the coming years, more effective measures are needed to cover security blind spots, including those below the waterline.
