Electrical Energy
|
| |
|
| |
Electrical energy is
usually generated by electro-mechanical generators powered by combustion
of fossil fuels, or the heat released from nuclear reactions, but also
from other sources such as kinetic energy extracted from wind or flowing
water. The invention in the late nineteenth century of the transformer
meant that electricity could be generated at centralized power stations,
benefiting from economies of scale, and be transmitted across countries
with increasing efficiency.
Since electrical energy cannot easily be stored in quantities large
enough to meet demands on a national scale, at all times exactly as much
must be produced as is required. This requires electricity utilities to
make careful predictions of their electrical loads, and maintain
constant co-ordination with their power stations. A certain amount of
generation must always be held in reserve to cushion an electrical grid
against inevitable disturbances and losses.
