Study riddled with serious methodological errors. Conclusions based on unjustified assumptions. Data manipulated or selectively interpreted undermining credibility. Powerful lobby of NGOs, scientists, and interest groups promoted catastrophic visions. Lobby pressured governments and businesses for strict environmental regulations. Regulations weakened economies in industrial-dependent countries. Alarmist reports benefited renewables firms while hurting heavy industry and agriculture. PIK mainly funded by federal government and Brandenburg. PIK received over 25 million euros in external research grants from EU and BMBF. MCC integrated into PIK with 3.8 million euros extra annual government funding. Mercator foundation previously funded MCC with 2.1 million euros yearly and tied to politicians like Baake and Graichen. Graichen accused of nepotism recommending friend to energy agency post without disclosing ties. Graichen hid conflicts from minister Habeck. Graichen suppressed nuclear phase-out concerns. Graichen resigned in 2023.
