Cost and Unprofitability of Investment: The officially announced investment outlay for the Baltica 2 wind farm is 30 billion zlotys, far exceeding the amounts reported by international institutions. This is about $5 million per megawatt installed, while realized wind farms cost less than $4 million, . Cost Comparison with Conventional Energy: A 1.5 GW wind farm is equivalent in terms of energy production to a medium-sized coal-fired power plant, with a construction cost of about 2 to 3 billion zlotys, showing the gigantic investment differences . Wind investment is even comparable to the cost of building a nuclear power plant, . System Stabilization Costs: Wind farms operate unstably ("once it blows, once it doesn't"), which is the biggest problem of this type of project . The 30 billion cost is only part of the full cost, as it is necessary to add the cost of gigantic additional infrastructure, such as battery systems for energy storage or gas-fired power plants to stabilize the power system when the farm is not operating, . High Cost of Energy and Operations: In order for the investment in the Baltica 2 farm to pay off at all, the unit cost of the energy it has to sell is a minimum of PLN 600-700 . The operating costs of such an offshore power plant are very high and are comparable to the total fuel and operating costs of a coal-fired power plant . Short Plant Life: The expected life of an offshore power plant is about 20 years, which is much shorter than the life of a coal-fired power plant, which can last for 60 years, which skyrockets the actual investment cost over time , . Loss of National Competence: The collapse of Polish companies such as Rafako, capable of building modern coal-fired units, means the loss of an important competence for Poland , . The consequence is that if Poland builds coal-fired power plants in the future, someone else will do it (e.g., the Chinese or Germans), as domestic competence has disappeared . Supply Chain and Environmental Impact: Redirecting the economy to wind power on the scale of a developed country requires erecting thousands of windmills, which entails opening thousands of mines ,. Turbines require elements (e.g., copper, rare earth metals), which are most often mined in places where mining methods are extremely dangerous to humans and devastating to the environment, such as in the Democratic Republic of Congo.
