- Take a structured approach
(click to read more...)Take a look at your electricity bill. Do you know what the different items mean? Do you know what a unit means? How many units are you using? How much are you paying for a unit? Do you have night rate electricity? How much electricity do you use at night? (Check out the links page to get the answers to these questions)
- Understand the market
(click to read more...)Make yourself aware of electricity suppliers in the market (see links page). Can you avail of cheaper electricity by switching supplier? How much are you likely to save?
- Deregulation of residential electricity market
(click to read more...)The residential electricity market was deregulated on 4th April 2011. This meant that Electric Ireland (formerly known as ESB customer supply) was free to set their own pricing for electricity. In response to this they announced discounts of up to 17%. However you will not automatically get these discounts, even if you are an existing customer of Electric Ireland. Here is what you need to do depending on who your current supplier is.
- Existing Electric Ireland (ESB) customers
(click to read more...)If you are an existing Electric Ireland (ESB) customer: You need to contact Electric Ireland (1850 30 50 90) and ask them to switch you to the new price plan. You will need your MPRN or account number which are on the top of your bill. You can automatically avail of an 8% discount by doing this. You can get an additional 4% discount by paying by direct debit (but you are not obliged to do this – if you do want to get this additional discount you will require your bank details to hand) and you can get an additional 2% discount if you avail of online billing – again you are not obliged to do this. Note: these figures apply for electricity only customers and do not take into consideration the additional discounts that are available if somebody wishes to switch their gas supply to Electric Ireland. However, it is necessary to contact Electric Ireland on 1850 30 50 90, even if you are an existing customer in order to avail of these discounts.
- Airtricity customers
(click to read more...)If you are with Airtricity: The Airtricity discount pricing only applies for the first 12 months that you are with them. Your unit rates will automatically revert to the higher rates after a 12 month period (and you will not be notified). If you contact Airtricity (1850 40 40 80) they can offer you an extension on your discounted rates for a further 12 months (this is being done in response to the Electric Ireland move). If you do not contact them you will be put on the more expensive rate 12 months after switching with no notification. If you wish to switch to Electric Ireland there is a precondition that you sign up for direct debit.
- Bord Gais customers
(click to read more...)If you are with Bord Gais: The discounted rates only apply for 12 months from the date of switching over. When I enquired if they would extend the discount for existing customers in response to the Electric Ireland move, their response was no. Therefore if you are with Bord Gais for more than 12 months you are on a more expensive rate. Their customer service number is 1850 63 26 32. If you wish to switch to Electric Ireland there is a precondition that you sign up for direct debit.
- Be aware of your consumption
(click to read more...)Do you know how to read your electricity meter (see links page for instructions on how to do this). Take regular readings to start getting an understanding of your usage patterns e.g. do you use more at weekends than weekdays etc. Identify what appliances seem to drive your costs
- Tackle big energy consumers first
(click to read more...)When taking steps to reduce energy costs, you will want to make sure that you get the biggest return for the effort you put in. It is vital to tackle your big consumers in order to have an impact i.e. if your washing machine is not a significant cost, then changing the temperature cycle is unlikely to have a significant impact on your bill. If you big cost is your immersion then you need to consider how you are using that.
- Be aware of the 2 basic steps to reduce costs
(click to read more...)
- Use cheaper electricity i?1 this can be by changing to a cheaper supplier, or by availing of cheaper night rate electricity
- Rational use of energy i.e. do not use more than you need. There are 3 steps to take when considering how you use energy i?1 see below.
- Rational use of energy
- Could an alternative energy source be used?
(click to read more...)For each unit of electricity used, there are 2.5 units used on the generating side i.e. 60% of energy is lost in the generation and distribution of electricity. This basically appears as cost on your bill. For residential customers, the average cost of one unit of electricity is approximately 15c, whereas the same unit of energy from natural gas or coal costs approximately 4.5c (source SEI report on Domestic Fuels Comparison of Energy Costs April 2010). Electricity is convenient but is relatively expensive compared to other fuel sources. Therefore if the same job can be done with another fuel source it will be cheaper. However you cannot watch TV using gas, you can however heat your house with gas i?1 space or water heating is expensive using electricity i?1 always consider alternatives for these purposes.
- Can duration of operation be reduced?
(click to read more...)It might seem obvious but if the duration a light is left on can be reduced, energy will be saved. A light left on in an unoccupied room is still wasting energy even if it is using energy efficient technology.
- Can less energy be used?
(click to read more...)Can less lights be turned on in the room, or can existing lights be dimmed. Either step reduces the total amount of watts being consumed at any point in time ultimately leading to less units of energy being consumed over time. Similar steps can be taken with other pieces of equipment, but each will have to be considered separately based on their operating characteristics etc.
- Could an alternative energy source be used?
- Consider each appliance separately
- Washing machine
(click to read more...)Reducing temperature of wash cycle used will certainly save some energy. This is simply because not as much electricity is required to get the water to the required temperature. However the same amount of water is heated regardless of how much clothes are in the machine. Therefore a more effective step is to make sure the machine is full, so that you are effectively getting more clothes washed for the same amount of energy. Of course when reducing the temperature of the wash there is always a risk that the clothes do not wash properly and you will be forced to rewash at the higher temperature which will have undone any of your efforts to save energy as a full extra cycle will have been wasted at the lower temperature.
- Lighting
(click to read more...)Energy efficient lighting. The temptation is to let your guard down when energy efficient lighting is installed. However remember that leaving the light on in an unoccupied room is still wasting energy even when it is an energy efficient technology that is being used. When considering what light bulbs to replace with energy efficient ones, always tackle those which are used most often first e.g. if a 50W halogen spotlight is to be replaced with a 3W LED equivalent, there is a saving of 47W for every hour of operation. This saves one unit of electricity after 21 hours of operation. If there is a requirement to have this light on 24 hours per day, this change will save over €62 in one year, based on a unit of electricity costing 15c. If the light is used for one hour per day it will only save €2.60 per year. Therefore a quicker return on investment will be achieve from lighting which is used more often.
- The mobile phone charger
(click to read more...)I am sure you have heard that you should unplug your mobile phone charger when not in use. I recently measured the current drawn by a mobile phone charger on standby to be 1mA. This equals 230mW. In one year this will waste 2 units of power (costing 30c). Unplugging the charger is unlikely to have big impact on your bill, and unfortunately you cannot rest on your laurels thinking you have now done your bit to save planet by taking that step.
- Standby
(click to read more...)Just like leaving a light on in a room that is unoccupied, leaving items on standby is wasting energy. But how much energy is actually being wasted? This will vary from appliance to appliance, but similar to the mobile phone charger any single appliance is unlikely to have a major impact. However the problem in modern society is that more and more appliances have become common place that are left on standby e.g. laser printer, computer, DVD and Blueray players, playstations etc. Individually these may not add up to much but collectively can contribute a significant amount to your bill. The solution is less about turning the TV off when not in use, but more about being aware of all the other appliances that are on standby and making sure they are turned off as well.
- Washing machine
- Some useful tools
- Constant Consumption
(click to read more...)When considering constant consumption i.e. items left permanently on or items on standby, the main thing to do is to raise your awareness of how many appliances fall into this category. The template below is intended to help raise your awareness by providing a means of recording all the items in your home that are potentially drawing power permanently and hence costing you money. To use it, simply go from room to room and make a note of everything that is left plugged in. You can then ask yourself which appliances are likely to be drawing power i.e. a lamp left plugged in but turned off will not be drawing any power so will not be an issue but a TV left on standby will. Once this is identified you may be able to identify appliances that you can turn off without having too much of an impact and in this way potentially save yourself some money.
Download Constant Consumption Template - Lighting cost tracking
(click to read more...)The second tool is to help you come to terms with how much your lights might be costing you. It is very difficult to accurately say how long various lights are left on. The intention with this tool is to again go through the rooms where lights are used, record the wattage, the quantity and the approximately hourly usage per day. The tool will then calculate the approximate contribution to your bi-monthly bill. (The unit rate with your current supplier can be adjusted at the top of the tool as well).
