Sun, nuclear fuels, oil, gas, wind, waves, rivers, animals, bio fuels.
Current alternatives include electricity, solar energy, and nuclear energy.
We use it for trains but instead we could be using something else like oil since that is what we use for our cars! Hope I helped! : )
In addition to carbon dioxide and water, respiration also produces energy in the form of adenosine triphosphate (ATP), which is used as a source of energy for various cellular processes in the body.
Conventional sources of energy usually include coal and oil - these have been used for many years. Natural gas is more recent, previously gas for cooking and lighting used to be made from coal. Coal has been used for centuries especially in Europe, whereas oil is a more recent development, mostly in the last century. Before that, transport was mostly fuelled by coal.
The Chinese workers use coal for making magnets or somthing else...
The higher the carbon content, the better the quality of the coal. In any piece of coal, whatever isn't carbon is logically something else - usually sulfur compounds (that's pollution when the coal is burned).
Oil and natural gas.
Underground, where else? (not strip mining)
You can use it in a coal burning furnace to heat your house, or you could throw it at your friends, birds, or anything else. You could probably carve something out of a lump of coal, like a nice bear or person. You could also round it into a ball and play baseball with it. Most people use it for energy, though. Not by eating it, but you could try that, too.
Your name
Because if it were something else you'd be asking why it is that instead of what it is.
Like everyone else by foot, horse, or wagon.
