Chapter 1 - Basic energy concepts*
11. Energy balance. An energy balance of a region (or country) is a set of relationships accounting for all energy which is produced, transformed and consumed in a certain period. This basic equation of an energy balance is: source + import = export + variation of stock + use + loss Consider a primary energy balance.

4. What are the environmental impacts of biofuel production?
Conventional petrol and diesel have fossil energy balances of around 0.8–0.9, because some energy is consumed in refining crude oil into usable fuel and transporting it to markets. If a biofuel has a fossil energy balance exceeding these numbers, it contributes to reducing dependence on fossil fuels .

Energy Production and Consumption - Our World in Data
We see that global energy consumption has increased nearly every year for more than half a century. The exceptions to this are in the early 1980s, and 2009 following the financial crisis. Global energy consumption continues to grow, but it does seem to be slowing – averaging around 1% to 2% per year.

The Earth-Atmosphere Energy Balance
The earth-atmosphere energy balance is achieved as the energy received from the Sun balances the energy lost by the Earth back into space. In this way, the Earth maintains a stable average temperature and therefore a stable climate. Using 100 units of energy from the sun as a baseline the energy balance is as follows: At the top of the ...
