Come on, I clutch:
Water savings:
rainwater recovery
brick in flush
outhouse
shower rather than bath ...
abandoning the dishwasher
Electricity savings:
Portable (30watts) rather than large PC (200 watts on average)
power management of large PCs
Low energy light bulbs, fluorescent tubes placed lower and with a reflector, localized lighting
rigorous management of the extinction of stores at 22 p.m. and of retailers
insulation and programming (electric heating)
Automatic timed lighting in certain rooms
devices in standby to "turn off"
tumble dry outside rather than tumble dry
rigorous management of lighting in offices: why do we leave them lit until very late when the cleaning team only comes there for 1/2 hour
modification of corridor lighting
better management and distribution of public lighting (I speak for Belgian motorways, we are getting there)
energy recovery from refrigerators in supermarkets,
confinement of the fridge area (Colruyt already does this in Belgium)
watch less bullshit on TV and make love more often
Heating savings:
electronic management - programming
remote management of heating in public and industrial buildings
modernization of installations: high efficiency boilers
elimination of corridor heating (by really modifying the installations)
auxiliary electric heating in the bathroom in 1/2 season in the bathroom
electric auxiliary heating when you are alone in the office during the day
insulation - lowering of ceilings
optimizing the choice of your home (type + location)
geothermal
solar
wood (is it really a solution? It saves oil but still generates C02)
sweater ?!
an airlock in stores
Gas savings:
use the microwave rather than the gas stove for your coffee (see ...)
wash hands with cold water
heating / insulation / etc ...
Fuel savings:
better management of trips: reservations, shopping list, telephone, internet, 4 X 9-hour week, change of suppliers, rationalization of tours, take out sandwiches
leave earlier, stay later, so drive slower and spend less time in traffic jams
send the kids to school by bus (I speak for Belgians!)
use of feet, bicycle, public transport
carpooling
change vehicle
put the airco less strong (23 ° in summer, that's good, 18 ° we catch colds)
pantone
magnets
Along with
hydrogen
water enrichment
wind turbines
Savings in materials:
choice of solid items
house made of recycled materials
recycled paper, installation of a failed photocopy box near the photocopier
frequent use of the container park
diligent waste sorting practice
I removed your:
food outside in winter rather than in the fridge (and unplugging the fridge of course, already being a student, it's great).
which I classify in dubious, unreliable and impractical practices, I only practice it for white wine, beer and lemonades when I receive. Anyway, the energy from your food is recovered in the kitchen and you lose energy when you open your door or your window
good i stop for today. Whose ball?
