Why might your power bills more than double by 2020?

Monday, October 11th, 2010

The Institute of Public Affairs last week issued some research, based on Australian Bureau of Statistics data, that revealed that retail electricity prices increased by 51 to 61 per cent in the most populous states of Australia between 2005 and 2010. These increases were up to four times the 16 per cent inflation rate over the last five years.

We believe that this trend of spiraling electricity prices will continue over the coming decade, with electricity rates to at least double and perhaps triple over the next 10 years. This would mean the average household can expect to pay an extra $1500 per year for electricity by 2020, equivalent to about an extra $30 per week taken from the household budget.

Such a large increase in retail electricity prices is expected due to the following five factors:

  1. Australia’s population is forecast to continue to grow, which means more investment is needed in the electricity network (transmission, distribution) to provide power to more people. This has to be paid for by the end user – households and businesses.
  2. Whilst many electrical appliances are twice as efficient as they were 10 years ago, Australians are using more power at home due to:
    • massive growth in purchases of large, power guzzling, flat screen TVs, often with two or three TVs in the same house
    • rapid growth in number of people installing air-conditioners and dishwashers in their homes (only about one third of homes currently have these)
    • increased multi-tasking especially among younger generation e.g. watching TV and surfing the Internet whilst listening to music
  3. Australia currently produces the majority of its power from cheap coal but the price of coal is likely to increase as fast growing countries like China and India demand more and more coal to fuel their rapidly growing energy needs. Local power generators are likely to have to pay prices for coal at higher international levels.
  4. State governments have in the past often kept consumer electricity prices artificially low but this trend has now come to an abrupt end as evidenced by the 15 to 20 per cent price rises in New South Wales and Queensland in July this year.
  5. The Federal Government’s mandatory renewable energy target dictates that by 2020 Australia must produce 20 per cent of its energy from renewable sources such as wind or solar. This will mean much higher costs to produce and distribute power to households and businesses because:
    • renewable energy power plants cost more to build and run as they are relatively new technologies
    • the networks that carry electricity from these new power plants to homes will need to be upgraded and extended at significant cost
    • wind power can be unreliable and would likely require back up power plants to ensure reliable supply

What can you do to reduce the heat?

There are two ways to keep your power bills under control:

  1. Reduce what you use at home – we recommend reading our electricity savings tips as well as requesting an energy audit to better understand where you might be wasting power at home.
  2. Reduce what you have to pay for this usage - regularly compare energy suppliers to ensure you are getting the best possible deal.

Energy prices might triple by 2020

Wednesday, April 14th, 2010

Origin Energy’s CEO, Grant King, is concerned that Australian energy prices might triple over the next 10 years. According to an article in The Australian, Mr King thinks that there are many reasons to expect energy prices to skyrocket:

  • Uncertainty over the federal government’s proposed Carbon Pollution Reduction Scheme (CPRS) resulting in investment in higher cost wind- and gas-powered generation;
  • Mandatory targets for renewable-energy generation;
  • Increased electricity transmission and distribution costs due to the need to invest in more infrastructure to support generation from renewables; and
  • Higher input fuel costs (e.g. coal & natural gas).

Mr Grant said that the average consumer is not helping either, using more and more energy by buying energy-inefficient appliances such as plasma TVs.

So it looks like the party might eventually be over for Australian households – historically we have enjoyed some of the cheapest energy costs in the developed world but in the decade to come we might end up forking out as much as consumers in countries like the UK.

Google gains approval to sell power in the US

Wednesday, February 24th, 2010

The United States Federal Energy Regulatory Commission (FERC) has given Google the green light to sell electricity and related services in the US. You might rightly wonder why Google would want to get into the power business and act as a utility – you think they would have better ways to make money.

Google says it wants to make itself carbon-neutral. Given the large number of data centres it operates, with probably thousands of servers in each, one could imagine the grand scale of Google’s electricity consumption. According to Google’s official blog, Google’s engineers did some analysis and found that an average Google search query consumes “about 1 kilojoule of energy and emits about 0.2 grams of carbon dioxide”. Obviously each search is tiny in isolation but multiply this figure by the billions of searches that it handles and it is clearly a big deal.

FERC’s approval gives Google the right to install as many solar panels as it likes in its quest to achieve carbon-neutrality. It also means that should Google generate lots of surplus solar power it could effectively resell this on the market; in other words Google could become a solar power generator and a net contributor to the electricity grid.

Google is already involved in energy in many ways, with applications like Google PowerMeter to assist consumers better manage their household energy consumption directly from their iGoogle homepage. Google has already signed up ten utility companies in North America and Europe to allow smart meters in their customers’ homes communicate with PowerMeter. There are also a couple of companies such as AlertMe in the UK selling self-install power management devices that are pre-configured to work with Google PowerMeter.

However, Google’s motives might not be entirely altruistic in helping the world use less energy; there is no doubt an excellent opportunity for Google to position itself as a large scale provider of energy management services to consumers and businesses around the world.
