Karten in diesem Stapel (20)
- 1What are non-renewable sources?Non-renewable sources are energy sources that are limited in supply.
- 2What are some examples of non-renewable sources?Some examples of non-renewable sources are:
-Fossil fuels such as coal, oil and natural gas. - 3How 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
- 4Reducing 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.
- 5In 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
- 6What happens if you purchase appliances that are efficient?Your household will save energy and save on running costs.
- 7What 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.
- 8Energy efficiency is shown by what?Energy efficiency is shown by the number of stars shaded on the label.
- 9What 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.
- 10What happens if the number is high?The higher the number, the more energy is needed and the more the appliance will cost to run.
- 11It 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.
- 12What is insulation?Insulation is a material added into ceilings and between the walls of a house to reduce heat transfer.
- 13What happens if insulation is added?It makes heating and cooling more effective and makes a house more comfortable.
- 14What is the National House Energy Rating Scheme?The National House Energy Rating Scheme uses computer simulations to provide a star rating for the built exterior shell of a house.
- 15What does a rating of zero stars mean?A rating of zero stars means that the house is poorly designed and does little to protect its occupants from heat in summer and cold in winter.
- 16What does a house rated at 10 stars mean?A house rated at 10 stars mean that it probably wont need any heating or cooling because it remains at a comfortable temperature all year round.
- 17What are some ways a house design can be improved?-Considering the orientation of windows
-Considering the orientation of the house
-Tinting or shading west-facing windows
-Including coverings over windows
-Insulating the floor, walls and roof - 18What 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.
- 19What is magnetic refrigeration?Magnetic refrigeration is a new way of providing cooling using a magnetic field.
- 20What are organic photovoltaics?Organic photovoltaics are a new generation of flexible and cheap solar cells made from carbon-based materials.
