Ed Miliband's ambitious plan for Britain to become a 'clean-energy superpower' by 2030 is facing criticism from various quarters, particularly regarding its feasibility and potential economic impact. Critics argue that his approach, which includes a proposed state-owned energy company, Great British Energy, lacks clarity and practical strategies for achieving net zero while maintaining energy security. Shadow Energy Secretary Claire Coutinho accused Miliband of making contradictory claims about profitability and investment risks, suggesting that his plans are unrealistic and misleading to both the public and industry. Furthermore, there are concerns that the reliance on renewable energy sources, while aimed at reducing costs, may actually increase energy bills due to subsidies for foreign energy companies. Miliband's recent requests for advice from the National Grid highlight a perceived lack of preparedness, raising doubts about the Labour Party's overall energy strategy. The opposition and some unions have voiced skepticism over the viability of decarbonizing the electricity grid within the proposed timeline, emphasizing the need for more concrete plans.
