Chemical energy is the most important type of energy on Earth. It accounts for 96% of all energy sources. These include oil (37%), coal (24%), natural gas (21%), and biomass (14%). These are 1994 figures. Chemical energy supplies the energy for all modes of transport, whether it ...
All life as we know it uses the exact same energy-carrying molecule as a kind of 'universal cellular fuel'.
To this day the Earth is kept active by gravitational, rotational, radioactive and solar energies. The convective mass transfer of heat driven or influenced by one or more of these forms of energy, from the very core of our planet through to the upper atmosphere, eventually conduces the ...
