The article discusses the lack of regulation and security risks associated with cloud-based management of solar panels in Europe, which could potentially lead to the collapse of the entire European electricity grid. Most consumer and business solar panels are centrally managed by a handful of companies, mostly from outside of Europe, with little to no oversight. This centralization of control creates a significant vulnerability, as a single hack or intentional action could simultaneously shut down millions of solar panels. The article calls for legislation and regulation to address this issue.
