Introduction

• Over the past few years, everyone in the world
  has started to worry about global warming and its
  effects.
• One of the main contributors to global warming is
  transport.
• There are many different methods of energy saving
  transport, but there are far too many to list.
• Today I am going to focus on transport to
  work/school.

3
Fuels

• Transport can harm the environment in many ways,
  one of the main contributors is the fuel they
  use.
• Some fuels can be very harmful as they produce
  lots of dangerous fumes and gasses.

• There is now a new range of fuels that are very
  energy efficient, and dont harm the environment
  as much. However, they can cost a lot of money to
  make and to use.

Cars

• On your way to work/school

5
Lift Sharing

• Lift sharing is a great way to save energy, as
  science has proved that two people in two
  separate cars is less energy efficient than lots
  of people in one car.
• So, find out who lives in your area and start
  lift sharing, you can make new friends and save
  energy!

6
Travel plan

• Travel plans use the science of map reading to
  make journeys quicker and more energy efficient.
• To make a travel plan, you need look up a journey
  on a map and work out which route is quicker and
  avoids major traffic jams on busy roads, this
  will mean that you would use less fuel and save
  energy.

7
Alternative Fuel Cars

• Scientific research has produced the following
  alternative fuel cars

• Electric Cars Pollution free, energy efficient,
  short range and lower speed, ideal for travel in
  cities where there are many recharging stations.

• Biofuel Cars These have been adapted to use
  fuel created from crops, unlike fossil fuels this
  is a renewable fuel source and environmentally
  friendly.

• Hybrid Cars Use the combination of a standard
  petrol engine with electric motors. Electric
  drive is used low speed and is ideal for city
  driving. At higher speeds the petrol engine is
  used not only for motion but also to recharge the
  batteries.

Trains

• On your way to work/school

9
Electric Trains

• Trains that are powered by electricity pollute
  the environment less and are energy efficient.
  They are also known for being very comfortable
  and smooth.
• However, they use a lot of electricity that has
  to be generated using fossil fuels. These, along
  with energy, are something that also need to be
  saved.

10
Solar Powered Trains

• Solar powered trains are a very good idea because
  they use the Sun as fuel instead of fossil fuels.
• The trains dont produce any fumes or gases, but
  if it is a cloudy day (which is very common in
  England) it would be very slow, or might not work
  at all.

11
The Maglev Train

• The Maglev train uses the science of magnets to
  move.
• If you put two magnets together with opposite
  poles facing, they attract. Then, if you turn one
  of the magnets around, so that the same poles are
  facing, the other magnet will be repelled and
  create motion.
• This is basically how the Maglev train moves.
  This is a very clever idea as it is very energy
  efficient, but the downside is that the trains
  cost a lot of money to make and run.

12
Buses

• On your way to work/school

13
Hydrogen bus

• Buses that run on hydrogen are a very energy
  efficient alternative to those that run on diesel
  fuels.
• These buses produce only water as waste and dont
  produce any gases or fumes.
• However, they are very expensive and the fuel
  cell used to produce the hydrogen takes a long
  time to make.

14
The Double Decker bus

• The Double Decker bus is a two storey bus. This
  is very energy efficient method as it is two
  buses in one so it uses half the amount of fuel
  and energy.
• These buses are starting to get replaced with the
  Two-Part bus, however there are still quite a few
  around.

15
The Two-Part Bus

• The Two-Part bus is two buses joined together in
  the middle.
• These buses appeared in the streets of London
  last year, and are starting to replace the Double
  Decker. Some of the buses can also run on
  hydrogen, but this is very expensive.
• Even though this bus can hold a lot of people,
  they are also wobbly, can get stuck around
  corners and create traffic jams because they are
  so long.

16
Conclusion

• There are many ways that science is helping the
  environment by saving energy and making transport
  more efficient.
• Trains are energy efficient because they can hold
  a lot of people and can use lots of different
  methods of saving energy. However, they can be
  inconvenient because they can only take you to
  the station so you might complete your journey to
  work/school with a bus or taxi.
• Buses are also an efficient means of transport.
  Environmentally friendly buses can be very
  expensive and increasing bus transport will add
  to the traffic congestion on the roads to
  work/school.
• Car journeys can be made more energy efficient by
  lift sharing at no additional cost. Furthermore
  drivers can now choose to buy some very energy
  efficient cars such as electric or hybrid.
• So, overall cars are the most energy efficient
  because they can save energy at a low price.

And, of course there is also good old walking and
cycling!
