Global emissions are still growing. That is due to global energy consumption growing faster then global renewable production increases. To avoid climate change, we have to not only increase renewable production, but also reduce energy consumption. We have to replace 139PWh of fossil fuel energy as quickly as possible. Last year we added 2PWh of new fossil fuels to the mix, but only 1.48PWh of wind, nuclear and solar. So just stopping the growth of fossil fuel energy production, would help more then all the clean energy we add.

However a fully clean energy system is possible. It is just a matter of getting to it quickly enough.
