The distribution of, and dependence on, technology varies markedly across the planet
Access to electricity is one of our most basic expectations, but it is not universally available
Digital technology
Countries at higher levels of development tend to have greater access to communications technology
Countries with a digital access index of over 75 are hyperconnected
They have the infrastructure to support digital information transfer and competition has lowered costs
Unsurprisingly, these countries correspond to the triad of economically wealthy areas - the powerhouse of the knowledge economy.
On the other side of the digital divide
are countries with index scores of 15 or
lower. These countries, largely in Africa,
are still far from entering the digital age
For such places, unfortunately, gaining access to digital technology is not simply a question of importing a lot of computer.
For internet technology to work, a range of other technologies and systems have to be in place, for example:
A wireless or hard-wired network
A reliable power supply
Internet service proider companies
A sales, distribution and repair network
Useful websites
and software in a
familiar language
Many benefits of the digital age have been slow to reach those who might have most to gain
Fossil fuels
A key feature of the developed world is its dependence on fossil fuels
Coal, oil and gas store energy fixed by
photosynthesis millions of years ago
Exploiting fossil fuels give us access to the vast amounts of cheap energy on which modern technology depends
Large-scale exploitation of coal began around 200 years ago, oil has been used
since about 1880 and natural gas only since the 1950s.
In 2004, fossil fuels supplied 86% of global energy use
Without access to the technology to exploit and burn fossil fuels, or the
money to buy them, much of the developing world is dependent on capturing
energy directly, for example by using biomass, wind or water power
Dependence on these sources restricts development
They are unreliable, small-scale and inflexible power sources
Our dependence on oil extends beyond energy
The petrochemicals industry, which refines crude oil into petrol, diesel and paraffin, also produces plastics.
The 20th century could well be
called the 'plastic century', as
polystyrene, nylon, PVC, synthetic
rubber, Teflon and ployethylene
were all perfected during this
period
Plastics are cheap, versatile materials and virtually all are made from crude oil
The cars we drive depend directly on oil for power, but the dependency is also indirect: many car and engine parts are made from plastics
If oil becomes scarce or very expensive, we will require a whole range of new technologies, perhaps very quickly
