If you are scared of a zero carbon economy, you are confusing "carbon free" with "climate change."

Bill McKibben:   "[I]f our goal is to keep the Earth’s temperature from rising more than two degrees Celsius—the upper limit identified by the nations of the world—how much more new digging and drilling can we do?

Here’s the answer: zero.

That’s right: If we’re serious about preventing catastrophic warming, the new study shows, we can’t dig any new coal mines, drill any new fields, build any more pipelines. Not a single one. We’re done expanding the fossil fuel frontier. Our only hope is a swift, managed decline in the production of all carbon-based energy from the fields we’ve already put in production.

... 

'Managed decline' means we don’t have to grind everything to a halt tomorrow; we can keep extracting fuel from existing oil wells and gas fields and coal mines. But we can’t go explore for new ones. We can’t even develop the ones we already know about, the ones right next to our current projects." 

Action on climate does not mean living in caves.

Action on climate does not mean hunting around in the dark.

Action on climate does not mean living without power.

That's what happens if we DON'T act on climate.
