2. ZCB - Making it Happen in Stroud
Part of Stroud Valleys’ Showcase week of events
1st to 8th October Energy, Food, Nature and Waste
A celebration of some of the very best environmental initiatives in Stroud and the Valleys in partnership with Stroud Nature. Eight days of activities and events from urban drainage to upcycling, from farmers markets to fast cars (electric ones that is), ending with Open Homes.
Go Electric
Event 1: Cars and bicycles to see and try, talk to owners, discuss benefits, practicalities and disadvantages. 2 hour afternoon at local secondary school’s sports centre.
Event 2: Evening workshop promoting the advantages of electric cars with a more detailed analysis.

Slow charge, fast charge
Which Car?
A bewildering range
Ethical Considerations
Battery materials and the car manufacturers’ policies
The Future
Bigger capacity batteries, longer range, better infrastructure

4. Results?
40+ attended first event including School’s Design and Technology class
Involvement of local dealers and Electric Highway
14 at workshop
One couple bought an electric car afterwards
Car Share Scheme looked into installing a charge point in one public car park where they park a car
Lack of off-street parking identified as greatest disincentive
Electric bikes encouraging more cycling in our hilly area
Greater understanding of the issues involved

10. Transport accounts for about 40% of Britain’s energy demand
The energy used for transport must reduce to match what is available from renewable sources
Transport accounts for about 40% of Britain’s energy demand
Industry will also emit carbon due to processes and supply of raw materials. How is this accounted for? 10

11. Is this chart per individual person?
We may have to change how we travel and how far but Electric vehicles will help to maintain our freedom of personal transport 11

12. Electric vehicles will use only renewable energy and use it very efficiently
How are the increased efficiencies achieved? 12

13. Do Electric Vehicles Reduce Greenhouse Emissions?
Electric cars produce zero emissions if they are run on electricity generated from renewable energy
Manufacture of Electric cars produces about 50% more emissions than a similar size petrol or diesel car
Whole life cycle emissions of an electric car are much less than a similar size petrol or diesel car

14. Reduced Costs
Fuel Costs of an electric car are much less than a similar size petrol or diesel car even using full price electricity
A medium size electric car will use 0.25kwh/mile on average
At standard rate, 15p/kWh = 3.75p/mile
At cheap rate, 7.5p/kWh = 1.9p/mile
Using free power = 0p/mile
Petrol at £1.15/litre & 50mpg = 12.65p/mile

15. Other Costs
An electric car generally costs more to buy than a petrol or diesel car of similar size, despite government grants
Using a medium size electric car will save = 8.9p/mile on average compared to a petrol or diesel car of similar size
If the electric car costs £2,500 more it will begin to pay off after 22,250 miles, less using cheaper electricity
Electric cars benefit from zero road tax (changes in 2017)
Ecotricity customers benefit from a £40/year discount on their electricity bill and free use of the Electric Highway subject to a fair use limit
Servicing and maintenance bills are generally less for an electric car
Leasing may be attractive, particularly to business users

16. Other Advantages
Electric cars give a smooth ride with no gear changing
They are quiet with only wind, road and external noise to trouble the driver and passengers. (Pedestrian warning sound added at low speed)
They are easy to drive and encourage economical driving but with good acceleration if required
Heating and charging can be controlled remotely when the cars are plugged in – warm and de-iced on a cold morning
Owning an electric car encourages their development and improvement and is a contribution towards a low carbon Britain

17. Managing Range Most UK journeys are short – less than 10 miles.
Home charging overnight restores full range (or at work if no off-street parking at home?)
For longer journeys a faster charge point is required
Plan a longer journey to take in one or more charge points using map systems/Apps
The Ecotricity Electric Highway covers the whole motorway network with fast charge points
A 30 minute fast charge restores 80% range
On board systems and smart phone Apps give real time location of charge points

19. Charging the Battery
Cars can be charged from a normal 13amp socket but this will take up to 10 hours for a full charge.
Home charging points can reduce the charge time to about 8 hours for a 3kW unit to 4 hours for a 7kW one.
Different manufacturers have introduced different standards for fast charging, which will deliver up to 80% full charge in 30 minutes.

21. Which Car? There is a wide range of electric cars on the market
As for any car purchase the buyer must consider their own personal wishes and requirements such as size, price, running costs, reliability, comfort, performance, etc.
Which? the Consumer Association Magazine now recommends several electric cars as Best Buys

22. Which Car? – City Cars
Used Option

23. Which Car? – Small Cars

24. Which Car? – Medium Cars

25. Which Car? – Medium Cars

26. Which Car? – Luxury Cars Tesla Model S Prices from £53,500 to £114,200
Tesla Model X

to £117,200

27. Which Car?

28. Ethical Considerations
Electrical components and Li-ion batteries in particular potentially contain conflict materials. Other components may be produced by exploited labour
There is growing demand for manufacturers to ensure ethically produced materials and components
Environmental control and reporting standards vary
Some manufacturers are taking measures to reduce the carbon footprint of manufacture
In general manufacturers continue to produce and sell polluting petrol and diesel cars

29. Ethical Considerations
This table is reproduced from the Ethical Consumer Ethical buying guide to electric cars website*available to subscribers only. The scores have been adjusted to take maximum importance of Environment. Scores reduce further if the importance of People is increased.
NOTES:
1. The bigger the Blob the bigger the ethical problem
2. No manufacturer releases quantitative emissions data for manufacture *

30. The Future?
Larger capacity batteries are already being introduced. These will give longer range but will place a demand for higher power charging infrastructure.
As the number of electric cars on the roads increases there will be increasing demand for more en-route charging points.
Increased demand for home charging will see solutions for on street parking and community charge points
Increased demand for workplace charge points
Autonomous cars will deliver themselves to your door?
