Hot Tips
Do you have a second fridge, in the shed maybe? If you can do without it most of the time, run it when you need it and turn it off the rest of the time and save around $120 a year in running costs. What you save in power, could pay for the drinks at your next party!

Most Efficient Heater?
With every salesman shouting the merits of radiant, or convection, or ceramic, or what ever other kind of heater they have to sell, it can be a nightmare trying to figure out which is the best to use, and the cheapest to run. However, if it has a power plug - working out the comparative running costs is easy...

How much power does it use?

All electrical appliances use power, but do you know how much?

Power is measured in watts, and your bill is charged in watts per hour, or more accurately kilowatts (thousands of watts) per hour. 1 unit of power, is 1 kWh (kilowatt hour), or put another way, 1000 watts used for an hour.

How much energy is too much energy?

A big part of saving cost, is reducing energy consumption. But how can you tell how well you are doing? One measure is to compare your own consumption with that of other energy consumers. You may already be using much less than others with the same size family, or perhaps you may find that you have room to do better on the energy conservation front.

 In this article, we present for you some statistics on average South Australian houshold energy consumption, so you can compare your own figures and see how well you are already doing...

Insulate and Save
The single biggest improvement you can make to the energy efficiency of your home is to insulate it.

It doesn't matter how efficient your heating or cooling system is, if your home isn't insulated most of your warmth or cool will be vanishing before you even notice it. Trying to heat or cool an uninsulated house is like drinking directly from a tap - you can quench your thirst, but a lot of water goes right down the drain!

  • Honeywell Wind Turbine by EarthTronics

    (Fri, 19 Jun 2009 16:00:00 GMT)

    EarthTronics, of Michigan, USA, says they have developed a wind turbine for residential and business customers that produces the highest output while having the lowest cost per kWh installed, at 1/3 the cost of any other wind generator on the market, and will be available through Ace Hardware stores in the Fall. Skeptics say this is hype not supported by actual deployment. (PESWiki; June 18, 2009)

  • Thorium as a green nuclear solution (FEN interview)

    (Fri, 19 Jun 2009 16:00:00 GMT)

    Robert Hargraves discusses the advantages of thorium, particularly the liquid fluoride thorium reactor, as a clean and safe nuclear solution that could compete with coal for inexpensive energy generation. Suggests a 10-year plan for bringing this forward. (PESN; June 17, 2009)

  • Sean CLaNZer's Replication of the Hamel Spinner

    (Fri, 19 Jun 2009 16:00:00 GMT)

    Drawing from information around the web, Sean has posted a series of videos showing his replication of David Hamel's all-magnet spinner. Though it doesn't accelerate, the rate of deceleration appears to be much slower than what would be manifest with a normal friction-based slow-down. (PESWiki; June 16, 2009)

  • NIST presently setting grid connectivity backbone

    (Fri, 19 Jun 2009 16:00:00 GMT)

    Right now at this very instant of time and for a very short period of time in the near future the standards for the transmission, formats and processes for all of the data handled in the Smart Grid are being written. Everything that proceeds for decades after this time will hinge on what we do in the next approximately 25 days. (PESN; June 13, 2009)

  • Welton Myers: A Grandfather of the Free Energy Movement (interview)

    (Fri, 19 Jun 2009 16:00:00 GMT)

    Welton has been involved in several amazing projects, including an electromagnet motor that levitated, patterned after John Searl's work; overunity electromagnetic systems of major output; as well as tire and vaporization devices. He's also had significant brushes with GEET, Brown's gas, and Stanley Meyers technology. (PESWiki; June 11, 2009)
