Each planting plan comes with an explanatory guide. How much embodied energy is there in a house? Materials such as concrete and timber have the lowest embodied energy intensities but are consumed in very large quantities; whereas the materials with high energy content such as stainless steel are used in much lesser amounts.

Thus the greatest amount of embodied energy in a building is often in concrete and steel. Burning coal to produce electricity is a major source of greenhouse gases. Green Power is a national program to promote electricity generated from clean, renewable energy sources. When you buy a Green Power accredited product, your electricity retailer purchases energy from renewable sources such as solar, wind, biomass and hydroelectricity sources.

Accredited retailers must not only source electricity from existing renewable energy sources, but must also contribute to the development of new generators using these renewable sources. For more details, contact your electricity retailer or call Sustainability Victoria on 03 or The car is central to our current way of life, but it is also a major source of greenhouse gases.

Developing a car that is non-polluting has been a dream of many designers. Cars powered by electricity and hydrogen have been designed and tested. A number of carmakers are developing what are called hybrid cars. The Toyota Prius, for example, is a hybrid car that uses a small petrol engine with an electric motor.

It provides low fuel consumption and low emission levels. Unlike fully electric cars, the Prius does not rely on heavy banks of batteries and nor do the batteries it uses need to be recharged. Recharging is done while the petrol engine is in use. The whole process is controlled by computers. Another car close to production is the aXcess Australia concept car. Engineers call this car a 'series hybrid'. The engine it uses drives a generator, which powers an electric motor that powers the wheels.

The major problem in a hybrid engine is the storing of electrical energy required for acceleration or increased-load situations, such as climbing a hill. The CSIRO has solved this problem by combining its own designs for a supercapacitor and a lightweight gel battery.

Together these form what they are calling a 'surge power unit'. A simpler approach being used in Australia is to run a purely electric car. It is now possible to convert small petrol cars to run on electricity by swapping the motor for an electric one and adding a bank of batteries. The car is charged up using a simple power point at home.

New cars designed specifically to run on electricity are also being designed and tested. Of course, green renewable power should be used to run such cars so that greenhouse emissions are kept to a minimum. Indeed it may be the case that running electric cars using coal-generated electricity would produce more greenhouse gases than using a petrol engine! Heating houses, particularly in cold climates, can generate many tonnes of greenhouse gas each year.

The amount depends on many factors including house size, the size and direction windows face, and the type of fuel used. Most homes in Australia are heated by natural gas or electricity. Other sources such as LPG, oil, wood and kerosene are used in some areas. A range of heating appliances has been developed to use the different energy sources. These are described below. There are two types of heaters that use gas, LPG or oil. Space heaters are located in a room, and heat that room and adjoining areas.

Ducted heaters are often located outside the house or in a cupboard. They heat air or water, which is circulated around the house to heat most, or all of, the house. Natural-gas heaters carry energy labels that show their energy efficiency. Wood can be used as fuel in an open fireplace, or in a slow combustion heater, which is usually a metal box with a metal or glass door.

A slow combustion heater is typically at least five times as efficient as an open fire. Briquettes, coal and coke can be burned in many slow combustion heaters. Kerosene heaters burn kerosene to produce heat within a room. They are usually portable heaters used to heat small areas. More information on types of heaters is available from your state Energy Information Centre, or local electricity and gas suppliers. Australians use portable fans, ceiling fans, evaporative coolers and air conditioners to keep cool during the hot months of the year.

All of these appliances are powered by electricity and thus contribute to greenhouse gas emissions. Fans create a cooling effect by moving air over people's bodies. As the airspeed increases, moisture evaporates more rapidly from the skin, removing more heat. Portable fans: These typically use little energy their power rating is about 40 watts , and generate one kilogram of greenhouse gas every 25 hours of operation.

Ceiling fans: These are permanently mounted on the ceiling of a room. They are very effective, and quiet. Typically, these use a little more energy their power rating is about 60 watts , and generate one kilogram of greenhouse gas every 15 hours of operation. Evaporative coolers: These range from portable units mounted on wheels that cool one room, to large, roof-mounted units with ducting, which cool a whole house.

Evaporative coolers are most effective in places where summers are hot and dry. They are essentially large fans that blow air through water-soaked panels of fibre. The evaporation of the water cools the air and humidifies it.

Evaporative coolers generate about a kilogram of greenhouse gas every 12 hours per room cooled. That is, if an evaporative cooler is used for four rooms, it will generate about one kilogram of greenhouse gas every 3 hours. Air conditioners: These work in the same way as a refrigerator. A compressor pumps a refrigerant fluid around through pipes. The refrigerant absorbs heat from the room, then pumps it outside. Air conditioners may Best Timber For Shed Shelving Error be simple wall- or window-mounted boxes, split systems which have a separate cooling module connected to the other components by thin pipes , or large central units with ducting to a number of rooms.

Air conditioners use more energy and generate more greenhouse gas than other forms of cooling but can often provide superior comfort in extreme heat, especially in humid conditions. Typically, an air conditioner generates about 1. When cooling a bedroom at night, around 0.

Some air conditioners can also be used for heating. These units, called 'reverse-cycle air conditioners' or 'heat pumps', are discussed in the section, Heating and greenhouse gas emissions. Few homes in Australia are without some form of refrigeration to keep food longer and drinks cooler. There are three basic refrigeration appliances: the single-door refrigerator, the two-door refrigerator and the freezer:. Most pre refrigerators and freezers used CFCs to form their foam insulation, and in their compressors.

To minimise damage to the ozone layer and greenhouse emissions, it is important that the CFCs are removed from their compressors before they are disposed of.

Your local environment authority can tell you where this can be done. Refrigeration is one of the largest contributors to household greenhouse gas emissions. A large, inefficient refrigerator can generate around two tonnes of greenhouse gas each year. New refrigerators carry energy labels, which show their energy consumption under standard conditions. Cooking generates greenhouse gases by using fossil fuels directly or indirectly in the form of electricity unless wood or hydroelectricity is used.

A large household can generate up to two tonnes of greenhouse gas per year as a result of cooking. Many families cook with natural gas. Natural gas consists mainly of methane, which is the simplest hydrocarbon. Natural gas, when burnt, emits less carbon dioxide per unit of energy than any other fossil fuel. An all-electric household, for example, would produce five times the quantity of carbon dioxide emissions produced by a household using natural gas for hot water, cooking and heating.

Methane is a powerful greenhouse gas. One kilogram of methane traps as much heat as 21 kilograms of carbon dioxide. Therefore gas appliances must be installed correctly to ensure no natural gas leaks into the environment.

In addition, poorly controlled emissions from the combustion of natural gas can reduce indoor air quality and, under some conditions, may even be harmful to health. A flue or chimney should always be used when burning natural gas. Natural gas usage in Australia is governed by rigorous industry technical standards and the industry has a good safety record.

In the past ten years, the gas industry has established industry standards for gas appliances to ensure emissions are well below acceptable limits. As well, appliance manufacturers have initiated research and development programs to develop improved burner technology, some of which have attracted export interest. Other initiatives include the laboratory testing and approval of all gas heaters for sale, free home environment testing, and low-cost heater servicing.

A range of appliances are available to heat water for domestic use. The most important ones are described below:. Hot water use can generate up to six tonnes of greenhouse gas each year. This not only depends on how much hot water is used and its source of energy, but also on losses from the hot-water service. Losses may make up around half of total water-heating energy. Waste is any material that is left over after being used, that no longer is needed for its original purpose.

Most kinds of packaging are only used once before they become waste. Other products like clothes and shoes may be used for years before they are no longer needed. Other items like electrical goods can become waste when they are broken. When preparing fresh food, parts of the fruit, vegetables or meat will not be used.

Often waste can be avoided by only purchasing what we need. A large percentage of food is dispose of because it was not eaten in time. Landfill sites can generate large amounts of methane gas. The warming properties of 1 kg of methane gas are equivalent to 21 kg of carbon dioxide.

Some old, unused landfill sites are designed to harvest this methane and generate electricity. When we create compost and mulch from green waste we are storing carbon in the ground and avoiding additional methane and carbon dioxide.
