"California boosted economic activity 19 percent per Btu of energy consumed between 2010 and 2015, to $3.29 in GDP for every 10,000 Btu of energy used, compared with $1.75 for the rest of the United States."
First off, that data in no way is related to the your claim that CA's population is growing faster than the rest of the country which I refuted above.
On top of that, the United States boosted economic activity per BTU faster than California over that same period. Here are the numbers:US GDP
Percent increase in US GDP = 21.1%US Energy Consumption
2010: 2235.6 MTOE
2015: 2227.0 MTOE
Percent decrease in US primary energy consumption = 0.4%
In other words, the US increased economic activity per BTU by 21.5% between 2010 and 2015 while CA only increased 19 percent over the same period.
The reason that CA's absolute energy intensity is lower than that of the US as a whole is because information technology and semiconductor technology give a higher return per unit of energy than most other industries. Nothing more.
The bottom line remains: CA is reducing emissions more slowly than the US as a whole. This fact is true even though CA is now growing more slowly and is partly because CA is unable to reduce the energy intensity of their industries as fast as the rest of the US.
It's funny how CA pats itself on its back about its improvement in emissions and it fails to realize they are lagging the rest of the country. What CA excels at is spending massive amounts of the taxpayers money and getting virtually nothing for it. That is why there is a mass exodus going on from CA right now
. This new legislation is sure to accelerate that exodus.
