At the start, several economists, environmentalists and non-profit organizations considered fracking to be a solid bridge technology on the way to a completely renewable energy supply.

“This is a real opportunity for your industry – this is not a ‘bridge to nowhere’ that we are talking about.  Natural gas provides a bridge to the future.  To the extent that you can deliver gas at a reasonable cost, you can be part of the solution to climate change.”

That statment from Eileen Claussen, president of the Center for Climate and Energy Solutions (C2ES), came from her controversial speech in 2008.

But now, fracking, or hydraulic fracturing, has come under fire from all sides. In fact, they believe it’s a counter-productive bridge to nowhere.

Oil and gas are becoming cheaper and competitive again due to fracking. That has in turn put the transition from fossil fuels to renewables in danger.

So what is the solution? Is there any way to reconcile the two driving factors, economic profit and ecologic sustainable development?

Or is there simply not enough research into the pros and cons of fracking yet?

Yale University posed that question to a panel of experts last September:

The opinions diverge, to say the least. If you are still new to the subject, get a short overview in the upcoming 5th and last part of the Global Ideas Fracking Blog series.
