It has become popular to demonise fossil fuels (FF). Pop stars, press, politicians and now Pontiffs speak with a single voice:
We know that technology based on the use of highly polluting fossil fuels – especially coal, but also oil and, to a lesser degree, gas needs to be progressively replaced without delay. Until greater progress is made in developing widely accessible sources of renewable energy, it is legitimate to choose the lesser of two evils or to find short-term solutions. But the international community has still not reached adequate agreements about the responsibility for paying the costs of this energy transition.

In this post I want to take a brief look at what FF have done for humanity and the environment. I will argue that in the 19th Century, FF first of all saved the whales from extinction and then through averting whole sale deforestation of the planet’s surface FF saved multiple ecosystems from destruction and as a consequence averted the extinction of thousands of species.
Figure 1 Population growth (blue line), right hand scale. Fossil fuel consumption (million tonnes oil equivalent) left hand scale. The exponential growth in population would not have been possible without FF. We all therefore owe the fabric of our society and our very existence to the use of FF over the past century or more.
Energy and Man
Every human being on Earth requires energy to survive (see list on Figure 1). Be it a handful of rice for the poorest Bangladeshi or the excesses of suburban life in the West, everything we do requires energy and in 2014 86% of that energy came from FF and 11% from legacy hydro and nuclear plant. Only 3% came from alternative sources. Worryingly, in a step back towards 19th century squalor, much of that 3% came from felling and burning forests.
Figure 2 This chart shows per capita productivity (a proxy for income) on the Y-axis and per capita energy consumption on the X-axis. The data for each country represent a time series starting in 1970 and normally progressing with time towards greater income and energy consumption. It is plain to see that there is great disparity in the per capita income and per capita energy consumption between countries. As a general rule, developing countries are striving to become wealthy like the OECD and hence show year on year growth in income AND energy consumption. See for example China, Turkey, Brazil and Belarus. To become more wealthy and more prosperous, in the common sense, requires us to use more energy.
It is simple and simplistic to make the argument that there should be a more equitable distribution of wealth and energy consumption. It is certainly rational to propose the reduction of waste and improved energy efficiency in the west. But competition and survival of the fittest is in our genes and makes us who we are. And there are certain benefits that flow from the wealthy to the poor, inoculation against deadly infectious diseases to name but one.
I am not arguing here in favour of greater polarisation of wealth but merely making the observation that it is a natural consequence of the socio economic models that appear to have served us well. I would warn against the growing politics of envy.
To become wealthy, the poor need access to clean drinking water, sanitation, food, and housing. All this requires energy and natural resources. The simplest and most economic way to provide this is through coal or gas fired power stations and the construction of electricity grids. To deny the poor access to FF is to condemn them to poverty for ever. It is fantasy to believe that the poor can be made wealthy (in the sense that the OECD is wealthy) by deployment of expensive and intermittent renewable energy. Like us, they may become wealthy only from using cheap, reliable and predictable energy supplies. This is not to say that there is no place for niche deployment of renewable energy in some developing countries.
