How Do Energy Save Light Help Environmet?
Additionally the environmental activists have now lobbied government to legislate for the ban. This is a phased initiative to eliminate the use of incandescents and move to energy save light. In this article I provide some data regarding how much you can reduce your carbon footprint by the change to energy saving light bulbs and how this economy compares with other C02 emission savings you can make by decreasing car travel or improved use of domestic electrical appliances. Lets now look at the data based on a usage of 4 hours per day and assuming you pay 13p per kWhour for electricity. You might well be curious how lamps can create carbon dioxide? Well they cannot and it is the electricity generating stations, which are normally oil or gas fired, which create the C02. Obviously if your electricity is generated by wave power, windmills or different green processes then C02 emissions will be very little. In this case changing one traditional incandescent will save a phenomenal 100kg per year in carbon dioxide emissions. Now for sure this exchange makes a significant improvement but what else?Dishwashers and washing machines do use around 3 kWhours of electricity each time they are used. As a comparator to a light bulb, if they were used twice a week, this is broadly similar to having 2 100 watt lamps on for 4 hours a day. Whilst these energy consumptions are definitely high they are not massive and to be quite honest washing machines and dishwashers are essential. So the focus here should be to always ensure that the appliances are full and don't use your tumbler dryer if the weather is good. I am sure you are questioning if 100kg of carbon dioxide emissions is a cause for worry and also whether it is not possible to make these carbon footprint reductions through other modes as opposed to changing to energy saving light bulbs? In order to respond to these questions I will offer then following data for appraisal. If you can alter your travel patterns to avoid 1000 miles of train travel, then this will save 100kg in C02 emissions. energy save light offer you a corresponding saving by just changing one! If you fly from London to Glasgow on a full plane then this will result in the release of 100kg in C02.If you own a Ford Focus C-Max vehicle and you can arrange to drive 340 miles less every year then this is an equivalent saving as changing one of your bulbs to one of your energy saving light bulbs.
