The EU is working on energy policies to help protect the environment. They have set goals for 2030, like cutting greenhouse gas emissions by 40% compared to 1990 levels and having 27% of energy from renewable sources. They also want to boost energy efficiency but haven't set a specific goal yet. The EU has earlier targets for 2020, like reducing emissions by 20% and increasing renewable energy to 20%. However, they realize more needs to be done by 2050 to ensure energy security. A study shows prices have gone up recently, but the EU is making informed policies to balance costs and benefits as they move towards cleaner energy.
