Solar cars are cars which run on the sun's energy, absorbed by photovoltaic cells.

Solar cars have not become available to the public yet and are still very much in prototypical stages. They are being developed in part by teams such as the University of Michigan Solar Car Team and the Massachusetts Institute of Technology Solar Car Team. These teams have competed in the World Solar
Challenge which is a solar car race in the Australian outback.

As environmental issues become more and more mainstream, consumers are looking closer at how their cars and their driving habits are affecting the planet.Various green technologies that apply to the automotive industry include:

• Bio diesel or biodiesel
• Solar cars
• Electric cars
• Hydrogen fuel cells
• Natural gas (CNG) cars
