With Europe at the center of an energy crisis, the world has never been more committed to a future powered by renewables.

The U.S. and the EU have already announced a major deal on liquified natural gas (LNG) – a fossil fuel, albeit the cleanest of them - in an attempt to reduce Europe's reliance on Russian energy.

A recent UN report, however, has warned we must revert to 'greener' options, having already made "irreversible damage" to the planet.

But despite major technological advances, making the switch still comes with its own challenges.

So, just how prepared are we for a future powered by renewables? And what would it cost?
