Abstract
The current development of renewable energy law (including, in particular, that concerning offshore wind power plants) requires the provision of adequate legal regulations allowing, on the one hand, for the greatest possible support for the planned investments and, on the other hand, for the maximum possible protection of the environment. In this context, it is important to ensure an appropriate level of constitutional–legal environmental security (both in the Constitution itself and in the laws detailing it). In turn, the development of the relevant normative regulations entails the necessity of their continuous optimisation (i. e., also with the use of relevant models of foreign law). Therefore, the aim of this article will be to present selected aspects of constitutional–legal environmental protection in the scope of offshore wind farm investments in the Polish legal system and the British legal system, which constitutes a valuable source of inspiration de lege ferenda.
