If you are interested in reducing your electricity bill, knowing your kWh usage is the first step. It begins by doing simple things like turning off the lights when you leave the room and adjusting your thermostat when you go to work. You can take even more control over your expenses by paying attention to your appliances. In addition, use energy saving appliances every chance you get. If you are in a deregulated electricity market like Texas , Ohio or Connecticut , you can shop for a cheap electricity rate.
Your local utility company continues to deliver electricity to your home, respond in the case of a power outage and read your meter. However, your supply can come from a competitive retail energy supplier. This allows you to pick from a fixed rate plan, prepaid electricity, free nights or free weekends, and green energy.
Or you can select the cheapest electricity provider in your area. Read more: 12 Ways to Reduce your Electricity Costs. What is a Kilowatt-Hour? Kilowatt-Hour vs. What Can a Kilowatt-Hour Power?
If you think your electricity usage is above what it should be, there are several things you should consider. If your house is old, it is likely it was built when the value of insulation was either not understood or unavailable.
The climate is also a major factor. If you live in an area that experiences very cold winters, super hot summers, or both, your energy usage will reflect this.
Climate control is one of the most power-hungry electrical users. Also, older appliances really are more energy-hungry than newer ones. Not long ago, TVs in standby mode often used almost as much energy as when they were in use, today they hardly use any. If you want to reduce your electricity usage and lower your energy bills, there are a few things you can do:. Kilowatt-hours give you a real handle on how much electricity you consume and how you can reduce that figure.
You can see which appliances are high-use items and which are more economical. When looking to buy a product, the kWh rating is an important one to take into consideration.
Not only does it give you an idea of how the way you use electricity in the home can be improved, but the cost per kWh gives you a direct comparison of one electricity supplier with another.

Or we could burn the biscuit and turn it into heat energy. Given the right equipment we could turn the heat energy from the burning biscuit into electrical energy to run lights and fans and so on.
Some energy would be wasted in the conversion process, but it should be possible to get that burning biscuit to run a light bulb for at least a few seconds. Probably the best option would be to eat the biscuit, but hopefully you get the general idea — the biscuit contains energy that can be converted into different forms Electricity and other fuels supply energy in a form that we can use to run the equipment in our buildings. Our biscuits contain a certain amount of energy — Calories or 0. But biscuit energy is not in a form that we can easily use to run the equipment in our buildings However, we can easily make use of electricity.
And, provided we've got a gas or oil burner, we can easily make use of gas or oil. One form of energy comes through wires isn't electricity clever?!
At the end of the day it's all just usable energy in different forms. We can express quantities of these forms of energy in terms of kWh. We buy or generate the kWh of energy, and we use it to fuel the equipment in our buildings. A typical building uses more energy over long periods of time than it does over short periods of time:.
Given the three figures above, we can easily see that the building used more energy over the course of than it did on February 16th, No surprises there. However, we can't immediately compare the efficiency of the building over each of those periods. If a kWh figure covers a day, we can only compare it fairly with other kWh figures that cover a day. If a kWh figure covers a week, we can only fairly compare it with other kWh figures that cover a week.
If we have the kWh from February and the kWh from March, we can't really compare the two figures fairly, because February is typically 28 days long, whilst March is 31 days long.
This article explains more about the problems that arise if you compare the kWh used in one month with the kWh used in the next. Energy consumption expressed in terms of kWh doesn't often mean much unless you also know the length of the period that the kWh were measured over. And it's difficult to make fair comparisons between kWh figures unless they are all from periods of exactly the same length.
Figures expressed in terms of power e. Strictly speaking energy isn't actually generated or used, it's converted from one form into another. Like how the energy stored in oil is converted into heat when you burn it. And like how the electricity that runs a fan is converted into the motion of the fan blade kinetic energy. But this is a distinction that people generally don't worry about when they're staring at an excessive energy bill and wondering how they can "use" less energy.
So power is a measure of how fast something is generating or using energy. The higher a building's kW, the faster that building is using energy. Joules per second makes it obvious that power is the rate at which energy is being generated or used.
It's like how miles per hour makes it obvious that speed is the rate at which distance is being travelled. The watt W is another unit of power. It doesn't make it quite so obvious what power means. But the watt is actually just another name for Joules per second.
Just some bright spark decided that equations and whatnot would be simpler if power had its own unit instead of being expressed using units of energy and time together.
And they named this unit after James Watt, the Scottish inventor who had an important hand in the development of the steam engine. The watt W is a measure of power And the kilowatt kW is a measure of power too one kW being watts. By following these tips you'll be on your way to reducing your energy bills and your carbon footprint. Small changes make a big difference. Read more.

What is a Kilowatt Hour kWh? Check Your Appliance The length of time it takes to use a single kWh depends on the appliance. If you switch on the shower or the kettle, you'll see the numbers jump. You can make decisions on your energy use based on real data Don't boil full kettles for one cup of tea, but make sure you have enough water to cover the element Try to use the washing machine and dishwasher at times when there is lower energy demand and avoid turning it on between in the morning and at night.
For every 10—20 seconds the door is open, it takes 45 minutes for the fridge to cool down to its original temperature Cover your pots and pans with a lid.
