Never waste a good crisis, Clinton says on climate
Secretary of State Hillary Clinton told an audience Friday "never waste a good crisis," and highlighted the opportunity of rebuilding economies in a greener, less energy-intensive way.

Highlighting Europe's unease the day after Russia warned that gas flows via Ukraine might be halted, she also condemned the use of energy as a political lever.

Clinton told young Europeans at the European Parliament that global economic turmoil provided a fresh opening. "Never waste a good crisis ... Don't waste it when it can have a very positive impact on climate change and energy security," she said.
