1. A method of producing portable electrical energy from a hydrocarbon-containing waste gas and preventing disposal of the hydrocarbon-containing waste gas by flaring, the method comprising the steps of:
a) producing the hydrocarbon-containing waste gas at a production site which is (i) an oil and/or gas well site, or an oil and/or gas production field, from which a liquid and/or gas product for transport from the production site is produced and the hydrocarbon-containing waste gas is an associated gas product produced at the production site which is not recovered with the liquid and/or gas product for transport, (ii) a landfill or other garbage or waste facility and the hydrocarbon-containing waste gas is a methane-containing gas which is produced and given off by the landfill or other garbage or waste facility, or (iii) an off-shore or on-shore loading facility for oil, hydrocarbon liquids, gas products, and/or liquified gas products and the hydrocarbon-containing waste gas is a gas which is vented by the off-shore or on-shore loading facility during operation;
b) driving an electrical generator at the production site to produce electrical energy by combusting the hydrocarbon-containing waste gas at the production site at which the hydrocarbon-containing waste gas is produced, with or without first removing solids and/or a liquid therefrom, in an internal combustion engine which directly or indirectly drives the electrical generator;
c) directly or indirectly delivering the electrical energy produced in step (b) from the electrical generator to, and storing the electrical energy in, a portable electrical power storage device or a portable set of electrical power storage devices which is temporarily located at the production site at which the hydrocarbon-containing waste gas is produced, the portable electrical power storage device or the portable set of electrical power storage devices being different from the electrical generator;
d) after step (c), transporting the portable electrical power storage device or the portable set of electrical power storage devices to a second geographical site, different from the production site at which the hydrocarbon-containing waste gas is produced; and
e) discharging a portion or all of the electrical energy stored in the portable electrical power storage device or the portable set of electrical power storage devices at the second geographical site to a receiving unit or system at the second geographical site.

17. A method of producing portable electrical energy comprising the steps of:
a) producing a gas or liquid product at a production site, the production site being (i) an oil and/or gas well site, (ii) an oil and/or gas production field, (iii) a landfill or other garbage or waste facility, (iv) an off-shore or on-shore loading facility for oil, hydrocarbon liquids, gas products, and/or liquified gas products, or (v) another geographical site at which the gas or liquid product is produced;
b) combusting a first amount of the gas or liquid product at the production site at which the gas or liquid product is produced in an internal combustion engine or a turbine engine to directly or indirectly power a first electrical generator to produce a first amount of electrical energy;
c) directly or indirectly delivering the first amount of electrical energy produced in step (b) to, and storing the first amount of electrical energy in, a portable electrical power storage device or a portable set of electrical power storage devices at the production site at which the gas or liquid product is produced;
d) combusting a second amount of the gas or liquid product at the production site at which the gas or liquid product is produced to produce a first amount of steam;
e) using an exhaust stream from the internal combustion engine or turbine engine to produce a second amount of steam at the production site at which the gas or liquid product is produced;
f) using the first and the second amounts of steam to drive a steam turbine at the production site at which the gas or liquid product is produced which powers a second electrical generator at the production site at which the gas or liquid product is produced to produce a second amount of electrical energy;
g) directly or indirectly delivering the second amount of electrical energy to, and storing the second amount of electrical energy in, the portable electric power storage device or the portable set of electrical power storage devices at the production site at which the gas or liquid product is produced; and
h) after steps (c) and (g), transporting the portable electrical power storage device or the portable set of electrical power storage devices to a second geographical site which is different from the production site at which the gas or liquid product is produced.
