Global
warming, is it the inconvenient truth as told by Al Gore?
Can we do
something about it?
What
should we do about it?
Well in
the perspective of planes, trains and cars I want to answer as much as I can.
So we
have
1) Aircraft.
· Highest output of CO2 every year
comes from flying.
· More flights are in used every
day due to customer demand.
· More flights by lost cost
airlines.
"The
two commercial aerospace giants Boeing and Airbus believe that the industry can
sustain itself against the increasing number of travellers each year. Airbus is forecasting a doubling of passenger
numbers within the next 20 years. Also it believes that that between now and
2030, airlines will need to order more than 29,000 new aircraft to cater for
increasing demand and to replace ageing and obsolete models. Boeing takes a similar view. Although it predicts
that airlines will need more than 33,000 new aircraft over the same
period." - http://www.bbc.co.uk/news/business-15571107
This is
worrying except for 1 key fact.
Both
airbus and Boeing are working alongside engine manufacturers to manufacture
aircraft which reduce CO2 emissions per km and increase fuel efficiency. The
smallest thing that has helped aircraft with emissions has been the
introduction of 'sharkeys' or wing tip fins. These allow the plane to use 95+%
of it wing to create lift therefore making the engine more efficient, without
changing the engine.
The most
recent example of this is the Boeing 787 recently released after 3 years of
delays. Airbus also has a similar plan in a new airline family - A350 XWB.
"Boeing
made the 787 Dreamliner to be most sophisticated plane built so far. It’s the
first airliner whose fuselage made out of a composite material rather than the
normal aluminium sheets riveted together. Its therefore lighter and faster due
to better weight to thrust ratio, the engine makers who provide the engines
(Rolls-Royce and General Electric) say that it will emit 20% less carbon
dioxide than similarly-sized planes do today." -

So with
these facts, airline manufacturers are making much headway into reducing their
products effect on the environment. However this appears like any gains will be
countered by increasing the number of planes in the sky. I believe this is okay
so long as more efficient technology is being researched too.
2) Trains.
· The least amount of CO2 emitting
form of transport when you look at electric railways.
· Still half and half, plenty of
diesel engines still in use alongside newer electric engines.
Trains
the only problems consumers find with trains especially in the UK is prices.
Even for a simple 10 minute journey you could be looking at £3 for a single
journey, however on a bus it would be £1.80 approximately and for bigger
distances, e.g. Liverpool to London - between £80/£150 return for a 2.5 hour
journey. Buses again are a lot cheaper, looking a National Express Liverpool to
London- £30, this however takes 3 times as long.
It just
depends on where you want to go too.
Train
services providers in the UK are actively encouraged to switch to electric
trains, but the upgrading of the tracks to electric is expensive and therefore
only new tracks are normally electric.
Diesel
engines however are being made to have more power with better fuel economy and
efficiency.
3) Cars.
3 types -
· Normal every day.
· Luxury every day.
· Supercars
Supercars
- every young boy normally dreams of one day owning a Ferrari or Lamborghini
but in a world that is so concerned now about CO2 emissions are they really
worth it. The kilometres to the litre economies are above 30km/l.
Yes these
cars are fast, and have engines that make most men quake with excitement, but
too have one you need in excess of £150000/$225000. Not to mention if you use
it as an everyday car a very deep pocket for any repairs and deeper still for
fuel cost per year. They aren't practical.
Everyday
cars - I drive a Nissan Almera, it has the power to go places and it’s willing
to haul ass and also coast on a gentle cruise. Its 5 door, standard 1.5l hatchback
and it’s all I need, with a tank of 60litres I can go 400-500 miles, normal
miles to litre ratio is around 9/10 in summer and 7/8 in winter due to cold
starts.
Then we
have the Luxury cars, Range Rover Sports / Vogue and the Porsche Turbo / Carrera
4s are these 2-4 litre cars necessary to drop kids of at school ( ~5miles) and
then go to work/ shopping (~20-40 miles) every day. Short answer is no.
There is
1 exception to this rule in my belief; those who require a bigger car with more
space are allowed them, i.e. disabled people and workmen.
The worst
part of these taller cars, like Range Rovers, is the people who drive them.
They have no concept of the rules of the road. Normally are pushy, and are normally
women who don't know how to drive them properly. In my opinions there should be
a separate driving test for these vehicles.
Again,
manufacturing companies are looking at many different ways of producing cars
and many (mainly the Japanese companies) have decided to invest in electric car
solutions. This is a reduction of approximately 80% in CO2 emissions, per mile
or kilometre.
So what
do you think??
Should
there be more planes in the sky??
Should we
have total electric train services??
Should
supercars and luxury cars not needed under certain exemptions be illegal??
Should we as consumers be urging
companies to bring more efficient technology into our cars, train and planes??
