Electrical energy is easy to make by several methods, but it is difficult to store. This is the reason that most devices that use electricity are stationary, so that they can be connected through the electrical power grid directly to electricity generating plants. Portable batteries and electrical generators are bulky and expensive.
Most of us are not aware, however, that our electrical power plants themselves are also batteries in a sense — huge installations that cost very large amounts of energy to construct. This construction energy comes in various forms, but all of it is fungible — that is to say is inter-convertible with electrical energy when estimating its value and availability. [Read more…]
