Every year we pump more than six billion tonnes of carbon emissions into the air from burning fossil fuel, despite a general consensus that this contributes directly to climate change.
Fossil fuels still provide almost 80% of the word’s total energy needs. And as countries industrialise, and their populations increase, their energy consumption also rises.
But beyond a certain threshold of wealth, energy efficiency begins to improve – if the right policies are implemented.
Today, more oil products are being produced worldwide than 30 years ago. But oil is a finite supply - and supplies will eventually run dry. Many experts believe that hydrogen, wind and solar power will provide most of the world’s energy in 50 years.
