Heh, hydrogen is not an energy source it's an energy carrier. Like a battery.
To get hydrogen you can extract it from gas or oil but you would be better off burning the natural gas or oil directly rather than using its hydrogen
to make electricity.
You can also electrolyse water but you get alot less energy out of the hydrogen than the electricity that you used to get the hydrogen. You also need
a serious amount of electricity, most of which comes from gas and oil currently.
Another problem with hydrogen is that it wants to be free
Its the lightest element and is hard to contain, hydrogen escapes from containers very
quickly. It also makes metal containers brittle so they break.
There is also the problem that hydrogen is nowhere near as energy dense as gasoline or natural gas. You could not run an airplane on hydrogen for
Basically there is no way that hydrogen could be used even on 1 thousandth of the scale that oil and natural gas are being used to sustain the world
economy and population.
Most people think that the energy problem will solve itself because humans are generally resourceful and clever. ie. People are generally optimistic
that we will find a solution because human civilization has been advancing for thousands of years.
The problem is that for the past 100 years we have been advancing because we found a staggering
amount of super cheap, easily recoverable,
energy dense, easily transportable chemical energy.
This fossil energy has allowed for the industrialisation of food production and so between 1950 and 2004 the world population grew by 4 billion
