More drivers will soon be able to take advantage of the subsidy for electric cars after the scheme was extended to cover a further 100,000 vehicles.
The plug-in car initiative, part of a £400 million package, applies to vehicles that use electricity for some or all over their journey.
Since it was first launched in 2011, the scheme has been taken up by around 50,000 drivers - half the number it is now being offered to.
But it is hoped the extension will encourage more motorists to buy into electric cars, which are already being made by manufacturers such as Toyota, Nissan and Tesla.
Further government schemes aimed at creating a greener Britain include the creation of clean air zones in five English cities over the next five years.
Birmingham, Leeds, Nottingham, Derby and Southampton are set to introduce tolls for polluting vehicles like old diesel buses, taxis and coaches to enter certain areas.
In addition, an ultra-low emission zone is set to be implemented in London in 2020.
