With the use of non-edible vegetable oils produced by trees such as Millettia Pinnata (formerly Pongamia Pinnata) or the Moringa oleifera tree, both which grow on borderline or non-arable land, the food versus fuel debate becomes less of an either/or question. Apart from their facility of growing in non-arable and/or marginal land, these trees ...
In December 2011, Ghulam Sarwar claimed he had invented a car that ran only on water. At the time the invented car was claimed to use 60% water and 40% Diesel or fuel, but that the inventor was working to make it run on only water, probably by end of June 2012.

A green vehicle, clean vehicle, eco-friendly vehicle or environmentally friendly vehicle is a road motor vehicle that produces less harmful impacts to the environment than comparable conventional internal combustion engine vehicles running on gasoline or diesel, or one that uses certain alternative fuels.
Also other battery electric vehicles, which may shift emissions to the location where the electricity is generated (if the electricity comes from coal or natural gas power plants—as opposed to hydro-electric, wind power, solar power or nuclear power plants); [5] and fuel cell vehicles powered by hydrogen, which may shift emissions to the location where the hydrogen is generated.
Plug-in hybrids and electric cars run off lithium-ion batteries and rare-earth element electric motors.Electric vehicles use much more lithium carbonate equivalent in their batteries compared to the 7g (0.25 oz) for a smartphone or the 30 g (1.1 oz) used by tablets or computers.
The engine powers the air conditioner on most cars, which means that running the AC burns fuel, reducing gas mileage by 1 to 4 mpg. And the hotter it is out there, the more energy your vehicle's ...

This means that a bicycle will use between 10 and 25 times less energy per distance travelled than a personal car, depending on fuel source and size of the car. This figure does depend on the speed and mass of the rider: greater speeds give higher air drag and heavier riders consume more energy per unit distance. In addition, because bicycles ...
