Many people fail to understand the difference between generating energy, and transporting it.


The main ways we can currently see to transport energy, ie for use in cars etc, away from the electricty grid are:

Stored Hydrocarbons- Petrol, gas, LPG etc,
Stored Hydrogen- fuel cells
Batteries.


The main ways we can generate power currently are:

Burning Hydrocarbons,
Nuclear Fission,
Geothermal power,
Tidal power,

Solar-derived power forms:
Solar power,
Wind power,
Hydro-Electric power,
Biomass burning.

Any other suggested power source has to be looked at carefully. Is it something new that actually generates power, such as nuclear fusion, or is it just a new way of transporting energy derived from one of the processes above.

If it seems too good to be true, it probably is.
