Saving energy today is a forced choice for two reasons: 1) our pockets Martori by the crisis we are grateful.
2) our planet and future generations will thank us much more
energy savings can be put into practice in two ways: first simply spend less, on the other take advantage of smarter energy that inevitably have to spend.
Probablemene the best known example, for its Diffusion in the media, the first type are saving light bulbs. We will analyze in detail.
outset are more efficient incandescent bulbs, because reduced by 80% the energy consumed .
are cheaper, they last at least 6 times longer than traditional bulbs, and its cost is amortized in less than 1 year . Finally
are more environmentally friendly, since significantly reduce CO2 emissions .
To get an idea of \u200b\u200bthe economic savings the new bulbs have prepared a simple table.
Traditional New Savings
40W 9W € 42
60W 11W € 67
75W 15W € 82
100W 20W € 109
Although these data are already quite illuminating, can get even more performance out of the new bulbs installed in the points home with more hours of power, because the frequent on and off the same reduced life.
Apart from the use of energy saving light bulbs can save on the lighting in the home advantage as much daylight as possible, leaving lights not in use, placing regulators light intensity, using fluorescent in environments with many hours of lighting, such as cooking, using light colors for walls and ceiling.
The lighting, however, represents only one fifth of household energy. The greater part is carried appliances and air conditioning.
With regard to electrical appliances are good habits:
always use the full-load washer ;
place the refrigerator in the coldest part of the house , if any;
LEDs off of all appliances, including explained in a previous article;
acquire, as far as possible, only appliances Class A + .
With regard to climate ideally have a home well insulated from the outside, as envisaged in the new planning law (this will also help reduce the rumors of the hated neighbor). The operations carried out, however, are made at the time of construction, so it will be difficult to improve this without a thorough reform.
As we crisis, hay que operar sobre otros factores para mejorar el aislamiento del hogar , y los principales son puertas y ventanas . Hay nuevas ventanas en comercio que presentan un doble hueco , distribuidos entre tres capas de cristal y aluminio. Esta solución tecnológica permite una diferencia térmica entre exterior e interior mucho mayor.
Una atención especial merece el uso que hacemos de la energía para calentarnos o refrescarnos, pues con 21º se mantedrá la casa warm in winter and 26 º cool in summer.
No more is needed, because, among other things, it is good to have a large temperature difference between outside and inside, it makes colds.
For every degree of temperature can reach save up to 7% on the invoice.
And finally, for those who can afford it, installing solar panels is, especially in a country like Spain, a wonderful solution energy savings that can be converted into profits even if we produce enough electricity for what is left us resell Iberdrola, which is required by law to purchase at a very advantageous to us.
In Italy and individuals who have paid off in 5 years the initial investment and are gaining about 500-800 € annual with photovoltaic installations.
