World Needs A Cheap, Clean Source Of Energy

In order to minimize the negative impacts of climate change, the climate science community has reviewed, in 2002 an approach called « the Kaya identity » which explains the factors involved in carbon dioxide output. This review is featured in the journal Proceedings of the National Academy of Sciences. The Kaya identity is a formula which gives insight on how the world can lower carbon dioxide emissions "down to zero.

Extremely concerned about climate issues, Bill Gates delivered in 2010, at the annual TED conference in Long Beach, California, a stirring speech in which he argued that energy innovation is the key to addressing climate change.

During his speech, Bill Gates unveiled « his vision » for how the world can reduce carbon emissions to zero and pleaded “that we have to drive full speed” toward achieving this goal. “Until we get to « zero carbon emissions », the temperature of the planet will continue to rise,” said Gates, “so we need to get to zero.” 

Recently, in the 2016 edition of the annual letter he and his wife, Melinda, published on Monday, Feruary 2016, Bill Gates released  a climate science equation that explains how the world can lower carbon dioxide emissions "down to zero,".  

The Bill Gate equation for lowering carbon dioxide emissions down to zero is nothing but the Kaya identity well known by the climate science community and reviewed fifteen years ago.

But no matter where the equation came from, it can help scientists keep tabs on carbon dioxide emissions.

Here is a snippet from Gates' annual letter explaining the variables. Bill Gate wrote :

Here’s what I came up with:

CO2 =     P     x      S       x         E      x      C
         

P : people   S : services per person    E : energy per service and C : carbon per unit energy

That might look complicated. It’s not.

On the left side you have the total amount of carbon dioxide (CO₂) we put in the atmosphere. This is what we need to get to zero. It’s based on the four factors on the right side of the equation: the world’s population (P) multiplied by the services (S) used by each person; the energy (E) needed to provide each of those services; and finally, the carbon dioxide (C) produced by that energy.
