Negawatts or ‘SAVED ENERGY costs half as much as the cost to produce the same amount of energy. The cheapest, cleanest and most secure form of energy is Energy Efficiency
RADIANT THERMAL CHEMICAL MECHANICAL GRAVITATIONAL SOUND NUCLEAR
Do example of lifting something fast or slow the same distance
Ask whether people know these abbreviations. Ask people if they know what they pay for a kWh or a MJ Do example of a 1000 W hairdryer running for 1 hour = 100 W light bulb running for 10 hours
Efficiency – doing more with the same or doing the same with less
Learning Points: Laptop consume less energy 1/3 rd or half (if attached to LCD). NOTE –kWh prices going up – est. 8% pa Often people turn off their PC but not the screen. Check your power savings settings on your computer While this is a BUSINESS example the move towards Remote Desktop – accessing your home computer from anywhere – requires it to be left on all the time. – Being promoted by Mircosoft.
Talk about Power Mates, Lux readers and Heat gauge. Also talk about the Home measurement system and the tools to cut energy
Point out that energy prices are going up so savings will only get larger.
This example is about what we did 10-15 years ago replacing old single light sources with a ceiling full of halogen. Problem is we are stuck with this problem. So what’s the solution – next screen
This example (payback) assumes you need to replace ALL your Halogen globes as well. If this is NOT required the payback is 8.8 months.
MEPS – Minimum Energy Performance Standard Energy consumption for entertainment quadrupled from 1989 to 2005 and is expected to quadruple again by 2020
Star rating based on 10 hours usage per day!!!! 5 Star LED rated at only 337 kWh pa
Compare purchasing 1 Star (1000 kWh) with 6 Star (350 kWh) = savings of $130 pa In 1986 TV usage accounted for approximately 3 PJ and in 2005 was estimated to have increased to approximately 12 PJ and is projected to exceed 45 PJ by 2020 (without the introduction of MEPS and energy labelling. The main drivers for the projected rapid increase in energy consumption are as follows: The average number of televisions per household is projected to increase from approximately 1.5 in 1986 to a projected 2.1 by 2020. One in four households now buys a new television each year. Most secondary televisions are used intensively. Hours of operation (which are higher than actual viewing hours) have been rising steadily over the study period from approximately 1500 per annum in 1986 to a projected 2800 hours by 2020 per TV. Newer technologies such as plasma and LCD have been driving a trend towards a very rapid increase in average screen size. This trend has resulted in a rapid rise in energy consumption from an average on-mode consumption of approximately 65 W in 1986 to 100 W in 2005 and continuing to grow to an estimated 230 W by 2020.
Why has the NSW Government funded a program to buyback second fridges? Almost a third of Sydney households have a second fridge. These old fridges are big energy users, consuming up to three times the energy of new fridges. While a second fridge may seem handy, the electricity costs averaging $265 a year are often hard to justify. Old second fridges also place an unnecessary load on NSW electricity infrastructure and cause unnecessary greenhouse gas emissions. The average household can save eight tones of greenhouse gas emissions by getting rid of the second fridge. Old fridges are also a source of ozone depleting CFC refrigerant gasses - which are greenhouse gases as well. Fridge Buyback degasses all fridges and environmentally destroys the refrigerants collected. The degassed fridges are subsequently taken for metals recycling. What is the NSW Climate Change Fund? Fridge Buyback is supported by the NSW Climate Change Fund. The Climate Change Fund was established by the NSW Government to fund programs and activities that save water, energy and greenhouse gas emissions in NSW. TERMS: That The Fridge To Be Collected is: 10 or more years old; 250 litres or greater in gross volume; and in working order, but not the main fridge, at the address listed.
With a bit of advanced preparation you can always have a cold beer ready for drinking – put 2 cans of beer in the family fridge the night before

Power vs Energy Energy is defined as the ability to do work Energy = Power x Time Power is a measure of the rate of doing work (recall the term ‘horse’ power?)
How do we measure Energy? kWh MJ 1 kWh = 3.6 MJ 1 Watt = 1 J / s Watt Joule
