The Distribution
As a matter of engineering, there are two primary ways to distribute the energy: microwave energy transmission, and fuel cells.

The first, and most convenient way of transmitting the energy would be to beam it directly to earth, using some sort of microwave transmissions, such as a rectenna, or candecent light transmissions. So far, only the rectenna seems to be viable in terms of efficiency, but new proposals are constantly being tried and tested.

Once the elevator is able to function as a two-way belt, however, it would also be able to carry charge along the cable, as well as carrying a constant stream of massive hydrogen cell batteries to be charged in space. This method has the drawback of needing to transport the energy from the poles after it lands, and compromising the security of the elevators themselves, but pipelines and tight security measures would allow for this alternative.

The Distributors
As a matter of politics, in order to insure fair pricing and global balance, no fewer than 1,441 companies will be allowed to indepenently manage the energy production and distribuition, and no more than ten percent of the companies can come from any single country, though all companies can operate internationally. Finally, an international body of democratically elected officials will police the companies to insure transparency and prevent price fixing.
