The 3 things standing in the way of sustainability

In an earlier post, we asked if it would be possible to power the world with clean energy. The United Nations believes it’s possible. So does the International Energy Agency (IEA). So what’s the problem? Why aren’t we there yet?

It’s not money that’s standing in the way, the IEA says in this video. Nor is it an inadequate supply of clean energy. Instead, the three things we need — but don’t have enough of, so far — to build a sustainable energy future will sound familiar to anyone who despairs while watching many of today’s political leaders in action (or, frequently, inaction): determination, creativity and courage.
