Summary
We flick a switch and energy flows. Energy is provided so easily for the developed world that thought is rarely given to where it comes from, whether it will ever run out or whether it is harming the environment. Energy is also cheap enough that little serious attention is given to conserving it. However, most of the world's energy comes from the burning of Fossil fuels, which generates a large proportion of the Greenhouse gas emissions into the Atmosphere. If these emissions are to be reduced, a large proportion of the reduction will have to occur in the energy sector. There is a need, therefore, to concentrate the minds of policymakers and indeed of everyone on our energy requirements and usage. This chapter looks at how future energy might be provided in a sustainable manner. It also addresses how basic energy services might be made available to the more than two billion in the world who as yet have no such provision.
World energy demand and supply
Most of the energy we use can be traced back to the Sun. In the case of Fossil fuels (coal, oil and gas) it has been stored away over millions of years in the past. If wood (or other Biomass including animal and vegetable oils), Hydro-power, wind or solar energy itself is used, the energy has either been converted from sunlight almost immediately or has been stored for at most a few years.
