Skeptical UN IPCC Scientist: 'The use of fossil fuels has done more to benefit human kind than anything else since the invention of agriculture'

The use of fossil fuels has done more to benefit human kind than anything else since the invention of agriculture.

Most of us would not be here if it were not for the use of fossil fuels because all human activity is enabled by energy supply and limited by material science.

Energy supply enables the growing of crops, the making of tools and their use to mine for minerals, and to build, and to provide goods, and to provide services.

Material Science limits what can be done with the energy. A steel plough share is better than a wooden one. Ability to etch silica permits the making of acceptably reliable computers. etc.

People die without energy and the ability to use it. They die because they lack food, or housing, or clothing to protect from the elements, or heating to survive cold, or cooling to survive heat, or medical provisions, or transport to move goods and services from where they are produced to where they are needed.

And people who lack energy are poor so they die from pollution, too.

For example, traffic pollution has been dramatically reduced by adoption of fossil fuels. On average each day in 1855 more than 50 tons of horse excrement was removed from only one street, Oxford Street in London. The mess, smell, insects and disease were awful everywhere. By 1900 every ceiling of every room in Britain had sticky paper hanging from it to catch the flies. Old buildings still have scrapers by their doors to remove some of the pollution from shoes before entering

Affluence reduces pollution. Rich people can afford sewers, toilets, clean drinking water and clean air. Poor people have more important things they must spend all they have to get. So, people with wealth can afford to reduce pollution but others cannot. Pollution in North America and Europe was greater in 1900 than in 2000 despite much larger populations in 2000. And the pollution now experienced every day by billions who do not have the wealth of Americans and Europeans includes cooking in a mud hut using wood and dung as fuel when they cannot afford a chimney.

The use of fossil fuels has provided that affluence for the developed world. The developing world needs the affluence provided by the development which is only possible at present by using fossil fuels.

We gained our wealth and our population by means of that use.

The energy supply increased immensely when the greater energy intensity in fossil fuels became available by use of the steam engine. Animal power, wind power and solar power were abandoned because the laws of physics do not allow them to provide as much energy as can be easily obtained from using fossil fuels.

The greater energy supply enabled more people to live and the human population exploded. Our population has now reached about 6.6 billion and it is still rising. All estimates are that the human population will peak at about 9 billion people near the middle of this century.

That additional more than 2 billion people in the next few decades needs additional energy supply to survive. The only methods to provide that additional energy supply at present are nuclear power and fossil fuels. And the use of nuclear power is limited because some activities are difficult to achieve by getting energy from the end of a wire. (If anybody doubts this then I tell them to ask a farmer what his production would be if he had to replace his tractor with a horse or a Sinclair C5).

So, holding the use of fossil fuels at its present level would kill at least 2 billion people, mostly children. And reducing the use of fossil fuels would kill more millions, possibly billions.

Improving energy efficiency will not solve that because it has been known since the nineteenth century that improved energy efficiency increases energy use: as many subsequent studies have confirmed.
