U-S Senator Dick Durbin says Illinois should start working to achieve energy efficiency and use green technology to combat climate change. The Supreme Court last week blocked a federal plan to limit greenhouse gases emitted by power plants. Durbin says it's time for Illinois to be proactive about saving the planet. "It's really going to help us in the future and for our kids, it's going to leave them a world they can live in." Nearly 30 states have filed a lawsuit challenging the President’s Clean Power Plan; Illinois is not one of them. The Supreme Court’s ruling puts the plan on hold while a lower court takes up the case. Meanwhile, environmentalists in Illinois are pushing the state to implement stricter renewable energy requirements.
