Reduce waste and increase efficiency


Climate change is real. The challenge is compelling. And the longer we wait, the harder it is to fix it. (John Kerry)

In a planet that because of human action appears to be on the brink of collapse, it is becoming increasingly urgent to adopt a lifestyle centered on energy saving. Energy is a precious commodity, and as such must be safeguarded. The reduction of energy consumption can be achieved: reducing waste and increasing efficiency. Besides the use of renewable energy sources -which would always preferire- you can take in the daily life of useful tips to protect the Earth and save a lot of money.

We never know the worth of water till the well is dry. (Thomas Fuller)

Water Saving

  • provide for proper maintenance of regularly scanning the pipes (a leaky faucet a drop in second disperses in a year some 5.000 liters),

  • install a mechanical filter self-cleaning that removes impurities that enter downstream from the aqueduct,

  • if the pressure is high, connect a pressure reducer on the inlet tube (saves up to 20%),

  • system install a backflow preventer that in case of backflow from the piping protects the networks of drinking water from potentially polluting fluid,

  • adopt a system leak-resistant to protect against flooding,

  • check the water hardness and possibly adopt a softener,

  • turn on the tap only when necessary to avoid unnecessary water slide,

  • use mixing of air to a water faucet to reduce power consumption without reducing the pressure,

  • install the cistern of the toilet with dual flush (flush each consumes about 10 liters),

  • for boiling to use only the amount needed and use any excess for rinsing the crockery.   

Electricity savings

  • use energy-saving bulbs adapted to the needs of each room (the walls be painted in light colors and use mirrors increases the brightness),

  • turn off the light in the rooms not lived (prefer natural light) and avoid continuous switching on and off (reduce the life of the bulbs),

  • if the water heater is used to adjust the maximum temperature about 60° C in the winter and 40° C in summer by programming the ignition via a plug timed,

  • choose appliances suitable to family needs in preference class A + or A ++, and remember to perform maintenance,

  • buy frost free refrigerators (where no frost forms) by placing them away from heat (which reduce efficiency), not introduce foods too hot and not too frequently open the door,

  • use the washing machine at full load and low temperatures, avoiding the pre-wash and using the proper amount of detergent,

  • opt for an electric oven without opening the door often (not to disperse heat) and turning it off in advance of the cooking time to exploit the residual heat,

  • operating the dishwasher fully loaded and with the proper detergent with care after removing food debris that clog the filter and thus counteract the washing,

  • where possible prefer drying laundry outdoors rather than resorting to the dryer and then use it in the most favourable days and time slots,

  • do not leave on standby television decoder, readers and computers (PCs set the fixed mode "Energy Saving" and remove the battery when the laptop is connected to the mains),

  • avoid non-essential equipment (such as electric kettles) and prefer the traditional to the cordless phone that is constantly fed (the same holds for alarm clocks and watches),

  • limit the use of air conditioners and use the thermostat to avoid creating too much imbalance between inside and outside (there must be no more than 5.6 degrees difference), use the "Dehumidification".

Saving Gas

  • carry out regular maintenance of radiators venting any excess air before ignition and during use to avoid covering them with tents and/or mobile,

  • in winter to keep the internal temperature not too high (at around 20/21° C),

  • for the purchase of a new boiler to choose the one condensing and anyway not leave out the annual maintenance of the heating system,

  • check the temperature of domestic hot water (not above 48° C),

  • resorting to double glazing and efficient windows to prevent heat loss,

  • in cold weather only open the windows during the hottest hours of the night and close all shutters or blinds to limit the cold outside,

  • cook in pans and pots provided with lid and in the case of very long cooking times, use a pressure cooker,

  • in the case of building renovations pay more attention to thermal insulation and in particular use systems and certified materials in green building.

The fight to save the global environment is much more difficult than the struggle to defeat Hitler, because this time the war is with ourselves. We are our enemy, as we have only ourselves as an ally.
(Al Gore)
