The Energy Detective
The first step to saving energy at home is knowing how much energy you use. This $145 household power monitor comes with a transmitting unit that taps into a circuit breaker, dual current transformers that are attached to power cables, and a receiving unit that plugs into a wall outlet to display real-time power use. All that hardware hacking is worth it, though -- TED
displays energy use for your entire house, and it connects to Google PowerMeter
, which means you can easily access energy data from your Google account.
Another great way to cut back of energy use and save on your bill is to avoid using energy when the grid is overloaded. The Energy Orb
is an ingenious eye-catching energy monitor that changes color to visualize the current grid load, thus displaying the relative price of electricity at any given moment. As creator Mark Martinez says, "It's non-intrusive... it has a relatively benign effect. But when you suddenly see your ball flashing red, you notice."
Visible Energy UFO Powercenter
Visible Energy's series of smart powerstrips
gather information on energy consumption every 5 minutes for all devices plugged into the outlets. An LED status light on the unit changes color from green to yellow to red depending on how much power is being used, so you don't have to check the numbers every time you want to see how much energy is being sucked up by your computer. Each outlet can also be set to turn devices on or off at specific times. No word yet on pricing for the powerstrips, but they're set to debut later this year.
The Kill-A-Watt is
an oldie but goodie in the world of home energy management. The device is simple to use: just plug it into an outlet and connect any gadget to find out its energy consumption by the kWh. Kill-A-Watt
can also calculate energy expenses by the day, month, and year. It's easy, cheap ($20), and effective -- what more could you ask from an energy-saving device?
Wiser Home Control
If you're really dedicated to saving energy, consider investing in a Wiser Home Control
system. The Wiser Home Controller can connect nearly every device in your house -- lighting controls, security, air conditioning
, audiovisual equipment, irrigation systems, motorized blinds and curtains, etc -- so that you can control everything via Internet or cell phone. So if you forgot to turn off the air conditioning, for example, you can easily do it from work or on your commute. The system comes with a range of options, so prices will vary.
SunPower iPhone App
Say you've already installed a photovoltaic array on your roof and you're looking to glean even greater energy savings. SunPower offers an innovative iPhone app
that lets you monitor the energy your solar system produces in real time. The Solar Electric Home Energy Management System
allows you monitor energy produced by SunPower solar systems verses your household's net energy use, so you can make smart decisions about when to use electricity.
This futuristic power-monitoring device
features a sensor hooked up to power cables, a wireless receiver and a readout on top of the box that shows energy consumption by the kilowatt or by cash spent. The box glows red, purple, or blue depending on how much energy is being consumed, so you can take a quick glance at Wattson to estimate your power usage. The device
