The dominant source of transport energy is oil. There are some alternatives:
Where the source of transportation is slowest.
Petroleum is the main source of energy for transportation.
Oil is clearly dominant in transport, and chemical feedstocks used to make a wide variety of products, and also important in many homes for heating. For electricity production coal is in fact dominant and oil is very little used.
In the early 1900s, coal was the most widely used energy source, powering industrial activities, transportation, and electricity generation. It was the dominant fuel during this period before being gradually replaced by oil and natural gas towards the end of the 1920s.

Biomass is the source of almost half of America's renewable energy.
The largest single source of energy used in the world today is oil. It is primarily used in transportation, industry, and electricity generation.
Oil became a major energy source in the late 19th century, particularly after the advent of the internal combustion engine and the rise of the automotive industry in the early 20th century. The 1859 drilling of the first commercial oil well in Pennsylvania marked the beginning of the oil industry, but its significance grew rapidly during and after World War I. By the mid-20th century, oil had established itself as a dominant energy source, largely due to its efficiency and versatility in transportation, heating, and electricity generation.
They have made solar cars, but not for the public to use. If you want a new source for transportation, try looking at hydro-cars. (water powered cars)
