Energy Consumption and Savings
Average
Consumption
The average person apparently emits 4.3 tons per person. (Developing
countries included). The average European emits close to 10 metric
tons of CO2 per year. The average American emits over 20 metric
tons - more than 6 times the world average.
In the UK the heating and lighting of the average home is around
6 tons, the average emissions per car per year is around 4 tons
and the annual rubbish from a typical home about 0.4 tons.
Long haul flight
The average long haul flight equivalent of UK to Australia return
produces around 3.75 tons of CO2
Medium haul flight
The average medium haul flight equivalent of UK to New York return
produces around 1.3 tons of CO2
Short haul flight
The average short haul flight equivalent of UK to Malaga return
produces around 0.6 tons of CO2
Central heating
If you adjust your thermostat by just one-half degree Celsius
during winter and summer months, the average household can save
907 kg CO2
Air Conditioning
Air conditioning is energy intensive and one of the conundrums
of modern living. AS the summers get hotter we need to chill our
homes, but the more air-conditioning we pump out the more we heat
the atmosphere by pumping out hot air (like a refrigerator). When
installing an air conditioning unit now it is better to opt for
a solar heating option. Apparently just replacing the filter regularly
on a traditional air-conditioning unit can save 79 kg CO2. Ceiling
fans use energy but far less. A ceiling fan instead of your air
conditioning and save 181 kg CO2. Help your air conditioner work
smarter, not harder; remember to replace your filter according
to recommendations and you can save
Lighting
Use energy-efficient light bulbs: Incandescent light bulbs are
becoming a thing of the past. This year, when your light bulbs
burn out, replace them with a compact fluorescent light bulb.
These fluorescent lamps fit into a standard socket, but have a
longer life and better energy efficiency. If you change just 3
light bulbs to compact fluorescent this year, you will save 136
kg of CO2.
Double glazing
Double glazing 6 medium to large windows could save 4,536 kg of
CO2
Wall and Ceiling Insulation
Wall and ceiling insulation can save 907 kg CO2 .Think about the
savings over the life of your home. Just 5 years with updated
insulation will save up to 4,535 kg CO2 .
Weather-stripping
Weather-strip doorways and windows can save 454 kg CO2 each year.
Hot Water
If you reduce the temperature of your water heater from 60°C
to 49°C (140°F to 120°F), you'll save 217 kg CO2.
Insulate your water heater for an additional savings of 454 kg
CO2. If you're in the market for a new water heater, go tankless
and save 136 kg CO2.
Fridges
Fridges are high energy users. Position in a cool place to begin
with and avoid putting hot food straight into the fridge. Regular
defrosting and cleaning of the coils can reduce consumption. It
might be worth considering replacing an old fridge with one of
the new models which are more energy efficient. An energy efficient
refrigerator can save 227 kg CO2 .
Recycling
Increasing home recycling by 10% saves the average household 91
kg CO2 over the course of a year
Packaging
Trimming garbage such as plastic containers and boxes by 10 per
cent can save up to to 454 kg CO2 within a year due to emissions
from landfill.
Meat
consumption
A diet of 30% meat, dairy and poultry produces 1,485 kg CO2 each
year, but a vegetarian diet generates only half of that. Animal
flatulence, processing, packaging and transportation of products
are to blame. If you replace red meat with fish, eggs and poultry,
you can save more than 430 kg CO2 a year. Alternately, eat meat-free
meals every other day for a 215 kg.
Reusable Items
Switching to a reusable policy like sponges instead of paper towels
and ditching disposable items and fashionable accessories for
long-term goods and quality products which can be repaired can
save an immeasurable amount of CO2.
Washing machines
A modern energy efficient washing machine can save 199 kg CO2
.
Clothes washing
Hot water is only needed for greasy or extremely dirty items.
Washing in cold water can save 228 kg of CO2 a year.
Tumble Drying
Tumble dryers are energy intensive. Forgoing tumble drying represents
a CO2 saving of 635 kgs .
Baths and Showers
A bath can take up to 190 litres of water? If you forego a bath
in favour of a shower just once a week, you can save 45 kg of
CO2. If you do this daily, it adds up to 317 kg of CO2
Showers
Showers account for 2/3 of water heating costs. Long showers are
the worst offenders. Each minute under an average showerhead uses
more than 9 litres of water. Cutting down on shower time results
in CO2 savings of 159 kg each year . If you change two showerheads
in your home to low-flow heads, you'll save 136 kg of CO2 each
year.
Computers
Idle computers across the world alone generate 45 million metric
tons of CO2, enough gas to fill 810,000,000,000 (810 billion)
balloons.
Electronic devices
Electronic devices, such as mobile phones, hair dryers, kettles,
etc, even when not in use, use electricity just by being plugged
in. By unplugging the average person can prevent 567 kg of CO2
from being released into our atmosphere.
Junk Mail
Junk mail is more than just a nuisance: 1 million trees are used
to create junk mail each year, and transporting this mail via
CO2-emitting vehicles costs €405 million (£275 million).
The average adult gets 19 kg of junk mail per year. If you cut
down on this waste, you can save up to 104 kg of CO2 every year.
Shop Locally
Supermarket food travels on average 2,500 km before it gets to
you. Each of those miles involves the emission of CO2. To avoid
this contribution, support shops that sell regional produce. If
you eat local food just once a week, you can save 2,268 kg CO2
over the course of a year.
Lawn Mowers
Modern reel push mowers are easier to use than they use the older
versions.
Hand mowers save 36 kg CO2 in a year.
Cars
The car we choose depends on what we need the car for and what
we want to get out of it. Whether it’s performance, size,
safety, business use, family trips or both, you don’t need
to compromise in order to reduce CO2 emissions. Simply choose
a more fuel efficient version or model of the type of car you’re
interested in. The more fuel efficient the car, the less fuel
it burns so less CO2 is produced. In fact, if everyone buying
a brand new car chose the most fuel efficient car in its class
we could reduce CO2 emissions from new cars by 24%.
Buying
a new car
Consider the size of car you want. In very general terms smaller
cars tend to be more fuel efficient and emit less C02, so ask
yourself questions about what you want the car for. The engine
matters when it comes to CO2 emissions. Once you’ve decided
on the type of car check out the different makes, models and engine
options. Most models offer a range of engines that vary in fuel
efficiency and CO2 emissions.
Petrol and diesel engines have different effects on the environment.
Engines powered by diesel generally produce less CO2 but more
than their petrol counterparts. If most of the driving you do
is long distance or motorway driving then consider a diesel engine
for fuel efficiency and lower CO2 emissions. If you spend more
time in town, where air quality is a greater consideration, then
a petrol engine may be the better choice. Most new cars in a car
showroom have a colour-coded fuel efficiency rating from band
A to band G, with bands A and B representing cars that emit the
least CO2. The lower the emission band, the lower the tax you’ll
pay. The label is also a guide to the running costs you can expect
for that car over 12,000 miles so you can compare how much different
cars cost to run. Fuel efficiency is an important factor. ‘Particulates’
are emissions released when fuel is burned that are harmful to
local air quality but on some cars a filter can be fitted such
as those with diesel engines.
Driving Slower
Driving slower means less carbon emissions.
Consider Smaller Families
According to the Optimum Population Trust (OPT) having two children
instead of three can reduce a family’s CO2 output by 620
return flights a year between London and New York.
Other ways to help the environment
Tree planting
Trees absorb the CO2 in our atmosphere while creating oxygen.
While tree planting has come under scrutiny recently sensibly
placed trees planted domestically (tree roots can cause pipe damage
which can also be environmentally unfriendly) can do a lot to
provide shade and shelter.
Estimates on savings
differ. Planting a tree native to your region in your garden can
apparently save 2,268 kg CO2 per year.
In fact the USDA
Forest service estimates a single mature tree can absorb carbon
dioxide at a rate of 48 lbs. per year and release enough oxygen
back into the atmosphere to support 2 human beings.
An acre of trees
absorbs enough CO2 over one year to equal the amount produced
by driving a car 26,000 miles.
If every American
family planted just one tree, the amount of CO2 in the atmosphere
would be reduced by one billion lbs annually. This is almost 5%
of the amount that human activity pumps into the atmosphere each
year.
Over a 50-year
lifetime, a tree generates $31,250 worth of oxygen, provides $62,000
worth of air pollution control, recycles $37,500 worth of water,
and controls $31,250 worth of soil erosion.
