Saving Energy With LED Light Bulbs

---

The easiest place to start when it comes to saving energy and money is switching to LED light bulbs. For instance, if you have 10 standard light bulbs in your home which come to the equivalent of 600W (0.6kw) and energy is sold in units of kilowatt-hours (kWh) is the amount of energy that a 1kW device uses in one hour. So for each hour you have the 10 standard light bulbs on you will consume 0.6kWh, and based on the typical average unit price of 12.2p per kWh, then the 10 standard light bulbs will cot you 7.3p per hour to run. Therefore if you were to have the light bulbs on for 10 hours each day and night you will be spending 73p per day. This is equivalent of £5.11 per week, £21.90 a month or £266.45 annually.

But by switching to the LED light bulb your cost will be cut significantly. If you were to replace all 10 bulbs with the 6W LED equivalent, the running costs will be just a tenth of the price at only 7.3p per day, 51p per week, £2.19 a month and only £26.65 a year. That is a massive saving of £239.80 per year.

Cost

So how much do LED light bulbs cost? Well for a standard average price the LED bulbs start at £7.00 each, and LED light bulbs have a lifespan of up to 50,000 hours compared with the 1,000 hour lifespan you get out of the incandescent bulbs which cost on average £1.30 each so over the course of the 50,000 hour lifespan of the LED you are saving £65 alone on the cost of the same amount of incandescent bulbs to cover the light hours of the LED counterpart would to make up for the the bulb where as electricity on a annual basis would be a lot cheaper. If you were to change just 10 bulbs in your house to LED bulbs that had a running time of 10 hours per day you would see savings up to £239 per year on electricity alone.
