Introduction

We are all aware of the energy crisis and of the fact that electricity is going to become more and more expensive.
Responsible people have already exchanged their incandescent light bulbs for the energy saving equivalent. They have turned down their geyser and insulated it with a geyser blanket. They switch off unused appliances and lights. Gas heaters have become more popular.
Energy does not only apply to electricity. Fossil fuels when burned provide heat energy. This is how we generate our electricity by burning large amounts of fossil fuels and then converting the heat energy produced to electrical energy.
In the process of conversion, a lot of the energy is lost. For heating and cooking many people go the direct route and burn something to use the energy produced. People without access to electricity have only this option and they will burn wood, coal, paraffin or gas to cook food and heat their homes. Wherever there are open fires there is the danger of houses burning down, people being burnt and toxic fumes being given off. However, with proper care this can be a fairly efficient way of utilising energy, especially if the fuel is renewable eg wood, charcoal, biofuels.
Then there is human energy. In our modern hectic world, we try to conserve our energy – to do things quickly and efficiently. Cooking is no exception. In the next couple of blogs I will be thinking about saving energy during cooking.
