the energy intensity of the global economy by 2.5 % per year on average between 2014 and 2050 (three - and - a-half times greater than the rate of improvement seen over the past 15 years); wind and solar combined would become the largest source of electricity by 2030.
Data on
the energy intensity of GDP show big variations across time and space, e.g. the sharp decline in US intensity after the oil shocks of the 1970s, which then flattened out as prices came down, and the much lower energy intensity of European nations with high gasoline taxes.
In the end, he said, much will depend on
the energy intensity of the overall economy and governmental policies that influence it.

the energy intensity of their economies.
(Note: C / GDP is in turn made up of two terms: E / GDP and C / E, or
Energy Intensity of the Economy and Carbon Intensity of Energy Supply)
The carbon intensity of the economy is the product of
the energy intensity of the economy and the carbon intensity of the energy supply.
That depends on population and economic growth, obviously, but it also depends on
the energy intensity of the world's economies — how much primary energy they require to produce a unit of GDP.
To do this, IRENA says,
the energy intensity of the global economy must fall two - thirds by 2050.
«India has already started reducing emission intensity, reducing
the energy intensity of development, increasing energy efficiency and also increasing the forest cover (to take more carbon out of the atmosphere).
The main countervailing factor is the reduced
energy intensity of economies.
Overall,
the energy intensity of the global economy would need to drop by a yearly average of 2.5 % up to 2050 — three - and - a-half times greater than the rate over the past 15 years.
