One of the first types of LED lamp The choice of lighting bodies must take into account two aspects: energy saving and quality of the light supplied. Both are important because if it is true that by installing efficient lighting fixtures you can reduce the energy bill, it is equally true that the quality of lighting affects living comfort (if we are talking about homes) and people's productivity (if we are talking about offices. ).

How to estimate electricity consumption: there are numerous methods, more or less accurate, to calculate the electricity consumption in the home. The most effective method is certainly the one that monitors electricity consumption directly from the meter or on the same electrical equipment.
The first tips we give you to save on your electricity bill see LED lamps as protagonists. The savings obtained with LED lamps justify the higher financial outlay at the time of purchase. LED lamps are latest generation low consumption lamps. LED lamps, by their nature, provide a light beam that does not overheat the environment.
We already know that incandescent bulbs are very expensive so much so that they are well on their way to getting out of our homes and never coming back. Most of us also know that LED bulbs are more efficient and are gradually supplanting other sources of artificial lighting.
We know that there is usually steel in reinforced concrete, that is, steel bars are inserted into the cement paste. Little known is the fact that the concrete of beams and pillars can also be reinforced with basalt fiber. Saving energy and with benefits for the environment. In 2010, ENEA began studying the potential of basalt fiber in reinforced concrete and other building applications.
The electronic invoice? It helps energy sustainability and is good for the environment. Among the advantages of this chapter of digital transformation - advantages that are primarily organizational and economic - there is also that of being more sustainable from an environmental point of view. Those who use electronic invoicing, technically e-invoicing, save money and pollute less.
Water waste in Italy: Italy is the European country where water rates are lowest, but it is also the one in which the water network is less efficient and has the most waste. Italy also has big faults when it comes to the purification of waste water. Water waste in Italy is caused by poor management of the water network and assisted by the less virtuous behavior of the Italians themselves.
Biogas is a biofuel composed mainly of methane and carbon dioxide. In biogas it is easy to find traces of other gases such as hydrogen, oxygen, nitrogen, carbon monoxide, ammonia and hydrogen sulfate.Production of biogas Biogas is produced by anaerobic digestion (in the absence of oxygen) with a biological process which organic, leads to the formation of different intermediate metabolites which are gradually transformed to the production of methane and carbon dioxide.
We often talk about electricity and less about thermal energy, that is, that part of the energy destined for the production of heat and cold. Yet the main item of final energy consumption is precisely that of thermal consumption. Obviously we are inclined to connect the idea of energy to light and the operation of appliances, but in this way we risk having a partial view of the topic.
Storing food in the refrigerator is necessary to preserve food through exposure to low temperatures. To better understand how to store food in the refrigerator, it is good to clarify that inside this appliance the cold tends to go down while the heat goes up. Once this simple principle is understood, it will be easier to place the food in the right place.
How to save water at home: strategies, devices, advice and good habits to respect to consolidate water saving in the home.To avoid damage related to water waste in Italy, it is possible to act on a daily basis and take action to save water at home. The data released by the OECD - Organization for Economic Cooperation and Development - show that the main water consumption is attributable to personal hygiene, and it is precisely within the walls of bathrooms and kitchens that we can implement strategies for saving water in home.
In the home environment, the energy used for space heating represents the greatest electricity consumption. The energy used for heating uses fossil sources, which are expensive and harmful to the environment. A heat pump can heat the house with excellent efficiency and, thanks to its ability to function as an air conditioner, it represents an excellent means of improving the comfort of living and working environments.
Each year, a Western consumer throws up to 253 kilos of food. This means that with every single person's food waste, the problem of world hunger could be drastically reduced, if not eliminated. Food waste can become a resource for the global community, so much so that the Food and Agriculture Organization of the United Nations (FAO) has published an entire dossier dedicated to food waste.
The internal mechanism of a twilight switch Switches are a 'basic ingredient' of the lighting system by regulating the on-off phase of the lights. With the right switches, that is, suitable for the particular use of light in that particular type of environment, you can save a lot of electricity and deflate your bill.
With the spread of renewable energies, the Authority for Electricity (Aeeg) has decided to change the system by introducing a new two-hour tariff that will go into effect from January 2013. Two solutions are being considered, the first sees the introduction of a three-hour rate and the second provides for a reduction in the evening slot that passes from the current 7:00 pm - 8:00 am to the restricted hours 11:00 pm - 7:00 am, these will be the times that will characterize the new two-hour tariff of 2013.
Energy saving with windows: according to the tools made available to window retailers, even by replacing only 5 standard windows (1.23 x 1.48 m in size), it would be possible to save at least 500 euros every year on heating costs! This projection is not so far from reality if we consider homes built over 15 years ago, when thermal insulation was completely underestimated and simple glass was used for the construction of doors and windows.
By smart home we mean the one in which the lights turn off by themselves if a room is empty, the heating system adjusts itself according to the outside temperature and the shutters rise and fall according to whether the sun beats or not. And something else. In short, a smart home is one where a home automation system regulates the operation of all or some systems with the aim of simplifying life and increasing the comfort of the occupants.
Operation diagram of a heat pump Currently around 400,000 electricity-powered compression heat pumps are installed in Italy. Added to the approximately 150,000 natural gas-powered absorption heat pumps, the installations of this highly efficient technology represent only about 2 of the total thermal production plants installed in Italian buildings.
A gas heat pump can be of the 'compression' or 'absorption' type. The first is a variant of the 'traditional' electric heat pump equipped with a compressor which, instead of electricity, uses the mechanical energy generated by a gas engine (methane or LPG). In the case of the absorption heat pump, without compressor, it is instead a completely different technology based on absorption refrigeration cycles.
The geothermal heat pump is a machine that allows you to exploit the ground as a natural resource to reduce energy consumption in the thermal uses of a building: heating, air conditioning and hot water production. Operation is based on the exchange of heat between a cold source, the ground, and a hot source, for example the heating system.
