Petroleum
Earth gas / Natural gas consists of methane with 0-20% higher hydrocarbons (primarily ethane). Earth gas also found correlated with other hydrocarbon fuel (methane clathrates), an important fuel source and a major feedstock for fertilizers.
a source that differs from the most commonly used resource. An example of an alternative fuel is corn oil or sugars, which would replace fossil fuels.
Liquid Hydrogen
Common natural resources are resources that are found almost everywhere and are made pretty quickly, these would include trees, water, and wind. Endangered natural resources would be any resource that is almost gone, which would consist of oil, coal, and almost every fossil fuel.
I'd go with Empire Earth 3, but that's just me
the earth's natural resources are oil,air,coal, wood, fossil fuel,and water
fossil fuel

They are very common. They are, for example, the most common fuel source.
i may not be right, but the energy source should be fossil fuel

Coal was used as a source of fuel and energy.
Natural resorces are the resources that are not man made and come straight from the Earth. Gold, Carbon, and Fossil fuel are natural resources, while plastic and rubber are not.
Fuel, Oxygen and a heat source. Fuel, Oxygen and heat are everywhere why is the whole earth not on fire? because it is not Heat but a source of ignition that is needed.
5,625,000 pounds of fuel. However, gravitational pull is also a main source of propulsion.
Coal was used as a source of fuel and energy.
An alternative resource, just as the term implies is a source of something which is different from the most common source. For example the most common source of automotive fuel is fossil fuels pumped from the ground, however it is possible to make automotive fuel from corn oil or from sugar. These would be alternative resources. These will help people in the future!
