Householders looking to compare energy might be pleased to hear that green cars are approaching their "make or break" year.
Dr Ben Lane, managing editor of nextgreencar.com, believes 2011 will tip the balance for or against electric vehicles, following on from a not "especially good" year for sales of such cars.
"It's still early days for electrical vehicles, but a number of key elements are all coming into place - partly because manufacturers have been working very hard to produce high quality models," he pointed out.
"2011 and 2012 will be make or break years and the signs at the moment are that it will be make."
He noted that while electric vehicles are not suitable for all drivers and all trips, they will still "find a sizable chunk of the market".
Cheap energy customers might recall that transport secretary Philip Hammond and business minister Mark Prisk recently unveiled nine electric vehicle models that will be eligible for grants of up to £5,000.
