Energy Saving Tips - Lighting.
Houses typically use a mixture of standard light fittings and downlighters or spotlight fittings. Energy efficient bulbs are available for both types of fittings from LED to CFL.
Changing which lamps (bulbs) you use and how you use them will instantly save your home energy and money. For example if you have x6 halogen recessed spot lights (which are mainly 50W each) in your kitchen that is a total load of 300 watts. Replace these with 4 watt LED versions and the total load is 24 watts, that is an instant saving of 276 watts.
There are two main types of energy efficient light bulbs available in the UK. Compact Fluorescent Lamps (CFLs) and Light Emitting Diodes (LEDs)
CFLs are what you typically think of as an energy efficient light bulb. CFLs are a cost-effective option for most general lighting requirements. Replacing a traditional light bulb with a compact fluorescent light bulb (CFL) of the same brightness will save you around £3 per year, or £45 over the lifetime of the bulb.
LEDs are available to fit both types of fittings and are particularly good for replacing spotlights and dimmable lights. Though more expensive to buy initially, they are more efficient than CFLs and will save you more money in the long term. By replacing all halogen downlighters in your home with LED alternatives, you could save around £40 a year on your electricity bills.
Turn lights off
Changing how we use our lights by implementing control mechanisms and being conscious of our behavioural habits can save money and energy. Here are a few easy things to help you start saving:
- Always turn lights out when leaving a room regardless of how short a period it is for
- Be conscious of how many lights you have on and whether they all need to be in use
- Arrange light switches so that its convenient to turn them off i.e. place switches at top and bottom of stairs, each end of a hallway and each door to a room
- Use a sensor and timer on external lights so they are only in use when they need to be
- Use appropriate lightings i.e. a low back ground light while watching television and a right, concentrated light for reading. By having a range of lights in a room with separate switches will make this easier.
Energy Saving Tips - Smart Meters.
Smart meters measure the total energy used in the same way as a traditional meter, but they can also tell you when you have used it and how much it costs. Additionally, they have a communication capability that allows this data to be displayed on a device inside your home and read remotely by your energy supplier.
An in-home display (IHD) unit will also be provided along with the smart meter as part of the programme. This device will be the most visible part of the smart metering system and provide up-to-date real-time information on gas and electricity use in pounds and pence, as well as units of energy.
The display will also present historical information on consumption so that you can compare current and past use.
The benefits of smart metersOnce your smart meter is installed, you will be able to see instantly when you're using the most energy – and how much it costs, whatever display method you choose. This means you can adapt your energy use in line with the smart meter information and cut down on waste to provide long-term carbon and financial savings.
For the first time, smart meters will allow households and businesses to make informed decisions based on accurate and real-time cost information. Currently many of us receive estimated bills after the energy has been used, making it difficult to reconcile costs with usage.
