A watt is a measure of power. It measure the rate at which electrons flow down the power line. A watt is not a physical thing. The easiest analogy to understand would be to compare it miles per hour. It is the rate at which energy is moving.
Understanding how watts affect your home and appliances is the first step to really understanding you electricity bill, and being able to lower it if you want. Watts measure the flow of energy, while the energy itself is measure in joules. A watt is basically the flow of one joule of energy per second. Therefore, a 60 watt light bulb consumes 60 joules of energy per second, and a 100 watt bulb uses 100 joules of energy per second. Your home’s energy isn’t measured in joules, however, it is measured in kilowatt-hours, or kWh. This is another measure of energy, like the joule. Unlike the joule, it is pretty practical for measuring household energy use. A watt-hour is the use of one watt for an hour. That 60 watt bulb uses 60 watt-hours in an hour. A kilowatt-hour is simply 1,000 watt hours, which is much more practical for displaying a home’s energy use than joules or watt-hours.
A household appliance’s energy usage is measured in kilowatt-hours and gives a person a good idea of what kind of energy needs that product has. For the most efficient products such as those made by Electricity Companies Texas Plano, people can look for the Energy Star label. Energy Star rated products have to meet certain standards, and the Energy Star label gives the estimated yearly kWh the product will use. With that information, a homeowner could estimate how much energy their home uses in a year or in a month. Finding the most efficient appliances can help cut down on power costs dramatically. The biggest power users are large appliances that run frequently, such as air conditionings and water heaters. By comparing the energy usage of different models of these appliances, a homeowner can make a smart decision regarding energy consumption and cut money from their electrical bill.
Understanding watts is not too hard. Simply thinking of a watt a mile per hour measurement for electricity can help. By looking at a household energy bill and the energy ratings for various appliances around the home, a homeowner can come up with a plan to reduce their energy consumption. Even if reducing power usage isn’t a priority, understanding your energy bill is always a useful skill to have.
