What determines the characteristics of fossil fuels?
When using the fossil fuels or hydrogen as an energy source (e.g., by combusting them to obtain heat), we extract their chemical energy. And, the chemical energy is stored in chemical bonds. Therefore, in so doing, we arrange the bonding of fuel, to obtain the difference of energy stored in reactants and products (see more […]
How much of energy can be extracted from fossil fuels?
The fossil fuels have been extensively utilized in our society, because they are extremely rich in energy (see Why we rely on fossil fuels?). This post tries to address, then, how much of energy do the fossil fuels possess? The type of energy that fossil fuels have is "chemical energy", which is stored in chemical […]
Why we rely on fossil fuels?
Our society has been relying on fossil fuels such as oil, natural gas, and coal. Why have we relied so much on these fossil fuels?
"drainage" of gasoline-powered vehicle?
A gasoline-powered vehicle runs by utilizing the energy generated through the combustion of gasoline. Primary products of the combustion reaction are carbon dixodies and water. How much of water does a gasoline-powered vehicle dischage?
"drainage" of fuel cell vehicle?
The fuel cell vehicle is driven by the energy released from a reaction between hydrogen and oxygen, and therefore discharges water of quantity same as the consumed hydrogen. How much of water does a fuel cell vehicle discharge?
