Abstract :
Sustainable, green, renewable, organic- the words come up so often in energy and climate debates that they tend to sound as if they mean the same thing. But of course they don´t. Nuclear reactors emit no carbon and are therefore in a sense green, but uranium is nonrenewable; hydropower is green and renewable but may not always be sustainable, because the ecological consequences can be bad and reservoirs are not limitless; coal is organic, but its carbon emissions make it the very opposite of green. All that is obvious enough. But even so, it may be jarring to hearas we have found and will describe-that organic biofuels can´t possibly fuel a growing world economy in a sustainable manner, whereas, in principle, inorganic fuels could.
