| What are some examples of non-renewable sources? | Some examples of non-renewable sources are: -Fossil fuels such as coal, oil and natural gas. |
| How can we reduce energy consumption? | We can reduce energy consumption by: -Switching of lights, computers and television when not in use. -Not relying on a car -Replacing inefficient globes |
| Reducing the amount of energy we use also reduces what else? | Reducing the amount of energy we use also reduces the amount of greenhouse gases put into the atmosphere. |
| In Australia, climate changes is likely to cause what? | -More frequent and intense droughts, storms and floods -Assist the spread of diseases -Alter the population of different species |
| What happens if you purchase appliances that are efficient? | Your household will save energy and save on running costs. |
| What is an energy rating label? | An energy rating label is a label showing a number of stars, which can be used to compare the energy efficiency of different appliances. |
| Energy efficiency is shown by what? | Energy efficiency is shown by the number of stars shaded on the label. |
| What does the number found on the label do? | The number found on the label provides the customer with an estimate of the amount of energy needed to operate the appliances for one year. |
| What happens if the number is high? | The higher the number, the more energy is needed and the more the appliance will cost to run. |
| It is estimated that half of the energy costs of running a house are on what? | It is estimated that half of the energy costs of running a house are to keep it warm in winter and cool in summer. |
| What is insulation? | Insulation is a material added into ceilings and between the walls of a house to reduce heat transfer. |
| What happens if insulation is added? | It makes heating and cooling more effective and makes a house more comfortable. |

| What is regenerative braking? | Regenerative braking is a vehicle braking system that stores some of the kinetic energy of a car as it slows down and uses this energy to power the car. |
| What is magnetic refrigeration? | Magnetic refrigeration is a new way of providing cooling using a magnetic field. |
| What are organic photovoltaics? | Organic photovoltaics are a new generation of flexible and cheap solar cells made from carbon-based materials. |
