Eli5 Renewable energy, becoming a net 0 world?

771 views

I’m listening to a podcast and the lady says we eventually will need to become a net 0 society and then go negative to reverse the effects of climate change.

This entails sucking carbon from the atmosphere. Why can’t we just invest in this now and keep our oil and coal energy? What can this carbon be used for once we have taken it from the atmosphere? She says we just pump it into the ground?

Well, when we burn a kilo of coal, we produce something like 3.6 kilos of co2. By volume, that’s a huge amount of gas. Far more than we can store anywhere.

To absorb this gas and convert it to something else, we need a shitload of energy. More than we get from producing it. So, we have this circular issue that requires non-carbon energy sources.

In the past, this non-carbon source has been the sun, which powers trees/other plants to break down and store carbon.
