Power Point Energy Meter Review
Description This device can indicate in real time what an electical device is consuming in electricity. Other functions include power consumed over time, dollars over time, CO2 over time. This meter can monitor a single power point. Any device plugged into the back will be measured. A internal coin battery will maintain recorded values even during a blackout. Review This device does monitor power consumption and is quite affordable ($20-$30). This price is much cheaper than other alternatives ($120 - $300). The accuracy of this meter versus others is good except at very low levels (< 5 watts). It has a tendency to read 0 or over 5 watts. This tendency would exclude this meter from reading some lower level standby consumption levels. The instructions state that the battery will last 3 months if not plugged in. This could be a limitation unless generally plugged in all the time or the battery is removed for storage which loses the recorded values. When the price and limitations are taken into account this still is a useful tool. Measure all electrical devices using a power point when on and in standby. Fridges can be plugged in over 24 hours to work out daily consumption levels. Computers may also need to be monitored over extended periods to work out the average consumption. Once all device consumption levels are known then total daily electrical consumption levels can be worked out. Now work out strategies for electrical efficiency. Energy Efficiency IdeasTurn devices off at the power point when not in use Turn off computers when not in use - Implement Computer Power Management options in BIOS and the operating system
Consider using electrical timers to control lighting and reduce standby loads Turn of lights when leaving a room Use sunlight instead of artificial light where appropriate Consider running only one refrigerator Select the most energy efficient appliances for all new and replacement purchases Use a clothes line instead of a dryer Front loaded washing machines use approximately 40% less power than top loading ones. Dress appropriately for the climate to save on heating and cooling Use fans instead of air conditioners where possible
Measure electrical consumption before and after changes and work out you savings. References http://www.jaycar.com.au/ http://www.ebay.com.au/ Top Energy Star products
