 Electric vehicles produce about 50% less CO₂
compared to petrol or diesel vehicles under
the current grid mix (King, 2008) and this will
decrease to near zero as the electricity network
is decarbonised. Running the entire UK car
and taxi fleet on electricity would require a
quantity equal to 16% of current electricity
demand (E4Tech, 2007). However, with use of
smart charging, electric cars should require
little or no additional electricity production
capacity because cars could be set to charge
when demand is low, such as during the night

A 1.5kW solar system will provide enough energy to run an EV for 17,500kms per annum (based on 4kWh’s per day/kW installed and 8kms/kWh). A 3kW solar system, operating at 80% output (due to temperature, cloud, dust etc) will provide the demand of 10 amps continuous current to charge a vehicle.

The CO₂ emissions from a modest four-star house with modern efficient appliances are about 6 tonnes per year. Emissions from a typical car driving 10,000 km per year are 1.5 tonnes per year. Installing a 5 kilowatt photovoltaic panel will fully offset these amounts of CO₂ by reducing the need to operate a coal fired power station.

China

EVs have been identified as one of seven “key strategic emerging industries” for the next five years. One hundred billion yuan ($US15.7 billion) of support over the next 10 years has been announced, with a view to getting 500,000 EVs on China’s roads by 2015, and five million by 2020. EVs are subject to 0 per cent sales tax and receive consumer subsidies of up to 60,000 yuan ($US9,400) from central government, which is doubled by some city-based programs. Source

Emissions from EVs

Power for electric cars (USA)

First, some key assumptions:

Average miles driven per US car in 2010 was 13,476.
EVs use roughly 0.3 kWh of electricity per mile.
That’s 4,043 kWh needed per year to drive 13,476 miles.
That works out to 11 kWh per day.
The DOE estimates that, in 2007, the number of US cars on the road was 254,400,000.

If all our cars were EVs, we would need to generate 2,798,400,000 kWh per day. Rounding up, let’s make that 2,798,500 MWh per day.

The average size of a wind turbine in the US has a power capacity of 3 MW. Using the average size, a wind turbine will produce 30.1 MWh per day (3 MW x 24 hours x 43% capacity).

To power 25.4 million EVs, we would need 92,973 3MW turbines.

At 0.25 acres per turbine, the total land required would be 23,243 acres.

For some perspective, the island of Manhattan contains 15,168 acres; Disney World covers 30,500 acres; and Washington, DC covers 43,712 acres.

Add in some losses for transmission and battery charging and the point is that we could get all the electricity needed to charge every car and light truck in the US with two Manhattans, one Disney World, or less than one Washington, DC.

Electric v​ehicle hubs

Cars can be converted to electric by replacing the wheels with ones with electric motors in them.

This one is from protean.

Mitsubishi have developed a similar in wheel electric motor.
