according to the website (Australian bureau of statistics) NT house households use very little amounts of solar energy and gas. it's surprising and a little ironic that South Australia uses solar energy more then the NT considering how much sunlight the NT gets while the of households that use solar is only 6.2% while South Australia impressively uses 24% across each household. while the NT once again uses very little gas as well coming up lower than the solar coming in at a staggering 3.2%. |

SOLAR ELECTRICITY Solar power is the conversion of sunlight into electricity, either directly using photovoltaics, or indirectly using concentrated solar power. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaic cells convert light into an electric current using the photovoltaic effect. Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. As the cost of solar electricity has fallen, the number of grid-connected solar PV systems has grown into the millions and utility-scale solar power stations with hundreds of megawatts are being built. Solar PV is rapidly becoming an inexpensive, low-carbon technology to harness renewable energy from the Sun. All across Australia 14% of households have solar panels to generate electricity. This includes all households with solar electricity with or without a solar hot water system. The use of solar electricity varied between the states and territories, nearly 24% households in South Australia 20% in Queensland and 16% in Western Australia used solar electricity. In New South Wales and Victoria, a significantly higher proportion of households outside the capital city used solar electricity compared to households in the capital city. MAINS GAS 50% of households in Australia used mains gas as a source of energy. In capital cities, nearly 63% of households used mains gas, and outside of capital cities 27% of households used mains gas.The use of mains gas varied between the states and territories. In Victoria 83% of households used mains gas, over 69% and 68% respectively of households in Western Australia and the Australian Capital Territory used mains gas, over 57% of households in South Australia used mains gas, 43% of households in New South Wales, 12% of households in Queensland, and 5% and 3% of households in Tasmania and the Northern Territory used mains gas respectively. ![]() Attachments:

The page seems to vary depending on what device you use to open the document. The Table of Contents says it's page 31. Abdul found it on 32. So just skim through the section "By region" as listed in the Contents. |

nearly everywhere in Australia has TV's, computers and phones each of which greatly surpassing 50% of which households have them.
the presence of TV's, phones and computers each of which increases the power input required to run them.
- •TV - nearly all Australian households - 98 per cent - had a TV, 35 per cent had two, and 20 per cent had three or more.
- •Computers - there's at least one tablet computer in 51 per cent of households; 69 per cent had a laptop, 10 per cent had three or more laptops in use, and there's still a desktop in use in 44 per cent of households.
- •Phones - 70 per cent of Australian households have a smart phone, and 47 per cent have two or more smart phones.
the stats are mad the power each house hold uses is just incredible, I mean just who needs two mobile phones.

Good points. Consider also the number of households which leave the TV on even when no-one is watching (there might not be statistics for this, the comment is based on personal observation); similarly computers, and phones being charged which - depending on phone type - if left on, can go on using power even after the phone is fully charged. Add to that air conditioners in a room or house that no-one is in (or heaters in cold parts of the country), fans turning all night in empty rooms, lights left on in several rooms all evening while the entire family is in just one room. Even appliances in standby mode use small amounts of power which add up to a lot of wasted standby power per household. Standby power is electricity used by appliances and equipment while they are switched off or not performing their primary function.1The consumer organisation "Choice" says Individually, most appliances draw only a small amount of energy on standby, but Australia-wide it adds up to an immense amount of power. It's often older appliances that use the most; energy-saving initiatives have generally made new appliances much more efficient in all respects.2

While searching though websites I've realised we've missed one of the most easiest ways to conserve energy, insulation, and the roof's colour. Insulation maybe one of the easiest things to understand out of the two but the colour of the can also help with maintaining a constant cool temperature. The lighter almost reflective coloured roofs tend to reflect heat better while darker coloured roofs which trap more heat. It's one of the reasons most houses you see when you walk around have silver or a light coloured roofs same goes for cars. Ever wonder why cars heat up so easily, it's manly to do with the colour scheme and the fact they have very little insulation. Houses with an notable higher amount of insulation block out more heat then houses without. |

Houses with an notable higher amount of insulation block out more heat then houses without. Well spotted jasonthemason5 - this is an important strategy. Not always the easiest to do something about (putting insulation into a finished house is not always straightforward and is much better done during construction). But it's worth the trouble: it's very effective in keeping houses cooler (or warmer, in wintery places), resulting in shorter periods of cooling or heating appliance use, and consequent saving of power. Another related measure is covering windows, ideally with outdoor blinds or shades, as this restricts the heat reaching the window glass, and so affects the indoor temperature. |

I learn that Power and Water Corporation will start using renewable energy in the future. Power and Water will incorporating more solar across in the remote communities in the NT due to the climate and geography. Power and Water is planning to build the latest power plant the Hybrid Diesel-Solar power stations it's an combined energy using less diesel and more solar. They planning putting the hybrid power station in the four remote communities; Bulman, Ti-Tree, Kalkarindji and Lake Nash with a combined capacity of approximately one (1) megawatt (MW). This hybrid project is called Solar Energy Transformation Program (SETuP) they planning to put 30 other remote communities in the Northern Territory which will reduce using diesel by 15 per cent across all communities and it will give 10MW. Power and Water is planning to put three 15kW wind turbines is installed at Alpurrurulam (Lake Nash). Power and Water has installed a 5kW hydro turbine at Manton Dam, about 70km south east of Darwin it was commissioning in February 2014, and supplies enough energy for four average Darwin homes. In the future Power and Water will continues to encourage the development of renewable technologies including tidal, bio-fuels, wind, solar thermal and solar photovoltaic to keep abreast of the best available technologies to incorporate into our systems. It will give supply a large-scale renewable energy power station in the 5MW to 50MW range with a nominal target of 30MW, to be connected to the Darwin to Katherine integrated system. The strong interest from the market in a range of renewable energy technologies will be used for Power and Water to take the next steps in integrating utility scale renewable energy on the largest power grid in the Northern Territory. 1

According to the Australian Bureau of Statistics, the Northern Territory has the lowest percentage of solar electricity used in households during 2014 and the highest is the South Australia with almost 25% of usage. In usage of main gas Australia is once again placed last with Victoria rocketing up over other states.
These may be the reasons why the Northern Territory uses less solar power:
• Installing a solar power at your home is very expensive
• Collecting solar energy is only available during daytime
• Batteries for energy storage is very expensive
Possible reasons why the Northern Territory use less main gas:
• Greenhouse gas emission
• Its not renewable
• Expensive pipelines

But do these factors only apply in the NT? Is installation more expensive here than interstate, where solar power is more commonly used? Collection is only available during the daytime everywhere else too, and the NT has more sunny days than many parts of Australia. Places with lots of exposure to sun seem ideally suited to developing this form of power. abdult14armata posted this on 4 November: "Power and Water Corporation will start using renewable energy in the future. Power and Water will incorporating more solar across in the remote communities in the NT due to the climate and geography." So maybe we will see an increase in the use of solar in the NT soon. |
