Energy, all energy, irrespective of its form, is the most important ingredient of life.
It drives all biological processes in the natural world and it drives all activities of modern humankind, from the food we eat to the devices carried in our hands. And our appetite and need for energy is growing at an alarming rate.
Within the next 30 years the world’s 7.7 billion people will become nearly 10 billion. With such growth we have a responsibility to ask ourselves two key questions:
- How are we going to feed all of these people? and
- Where is the energy required to do so going to come from?
These two questions go hand in hand – you cannot produce the volume of food needed to sustain a population in the multiple billions, without expending a significant amount of energy.
