How to save on electricity is certainly one of the issues in our everyday life and allows us to give our contribution in the field of environmental protection.
Presently we are in the energy conservation and renewable energy development era and the sensitivity for the environment and preservation of the planet is gradually gaining fortunately more and more layers of the population.
In this context, along with solar panels, wind power and other forms of renewable energy, one of the simplest and straightforward way to implement this process is undoubtedly represented by the replacement of all incandescent lamps in our houses. In fact the simple replacement with fluorescent lamps that provide significant savings both in economic terms as pollution, must adopted by each of ours providing a great immediate saving of energy.
According to a program to disincentive the usage of incandescent lamps, in the entire European Union the production and sale of these lamps have been stopped in order to achieve a consistent energy saving with a simple act.
Lamps can be:
- incandescent lamps
- halogen lamps
- fluorescent lamps
To better understand what follows, especially to non-expert, it could be usefull to give some generic definition:
- Luminous Flux – Units Measuring Lumen (lm) – it is the amount of light emitted in a unit of time
- Intensity ‘Bright – Units’ of measurement: Candela (cd) – concentration of the light radiated in one direction on a portion of a sphere
- Illuminance – Units of measurement: Lux (lx) – amount of light on a surface tangent to the beam
To get an idea of the energy savings achieved, just think that to produce 600 lm we must use:
a 60-watt incandescent bulb
a 42-watt halogen bulb
a 12-watt fluorescent bulb
It is quite evident the importance of starting to get used to assess the power no more according to Watts, but the lumen.
Making a comparison about the advantage of one system over another is not easy because you have to consider several aspects to find out what system collects more benefits.
- Energy consumption
- light output (lm)
- ignition time (time interval between switching on and optimum level of exercise)
- sensitivity to the temperature
- loss of intensity in the life time
- heating effect of the bulb
Through an analysis of the various parameters can be achieved a meaningful comparison having in mind that if on the one hand it is true that the cost of fluorescent lamps is higher, the duration of these lamps is well above and the consumption well below, therefore, in addition to the good environmental impact, we are getting a significant cost savings.
Here we have not covered the LED lamps, which, although already on the market, are still a niche product with costs still high and that probably once normalized the production and distribution processes will find the welcome they deserve, and perhaps represent the solution in the coming years.
The process of energy saving to achieve a sustainable impact on the environment is a collection of many interventions, but above all it is a cultural attitude, difficult to achieve. However each step is important and is a step toward a greener and less polluted planet.
