The switching power supplies used today are much smaller and lighter. They convert the 60-Hertz (Hz, or cycles per second) current to a much higher frequency, meaning more cycles per second. This conversion enables a small, lightweight transformer in the power supply to do the actual voltage...
When your power goes out, a generator can be a lifesaver. The downside, though, is fuel consumption. A traditional gas generator can go through gas quickly. Learn how much gas different types of generators use so you can find the right generator for all your energy needs. What Are the Di...
Newer OLED displays are on the horizon and will have a significant reduction in power consumption. Sustained hard disk usage consumes an average of around 5 percent of total power consumption in a mobile PC. New solid-state drives are much more efficient, because there is no mec...
The United States consumes 26 percent of the world's energy. Of that energy, approximately 5 percent is vampire power [source: University of California, Berkeley]. To put that in perspective, that's between 200 and 400 terawatt hours -- roughly as much electricity as the entire country of ...
As the name suggests, a bidirectional meter facilitates the transfer of AC electricity to and from the utility grid. It also monitors how much grid power you consume vs. how much you supply and adjusts your electricity bill accordingly. If you qualify for net metering, many utilities and powe...
But the biggest electric desk fans (typically rated 25–50 watts) use a fraction as much power as the smallest air conditioners (typically rated at 750–1000 watts); you could use about 20–30 fans and consume the same or less power than a compact AC unit! [1] Photo: The ozone hole...

How much electricity will average wash use? Let’s presume that we have a 500W washing machine that runs for 3 hours. Just plug the 500W in the power consumption calculator above, and we get: We see that the 500W washing machine uses 0.5 kWh per hour. In 3 hours, that is 1.5 kWh....
At this point, you should already know how much energy does an average house use. A household typically consumes approximately 800 to 1,000 kWh (kilowatt-hours) of monthly electricity. To save more energy, you can start by switching appliances to energy-efficient ones with ENERGY STAR...
How much power does a 1.5-ton AC use? A 1.5-ton air conditioning unit typically consumes around 1.5 kilowatts per hour. However, the exact power usage can vary depending on factors such as the unit’s efficiency, the temperature setting, and the outside temperature conditions. It is worth...
