INCREASE THROUGH SAVING

Some materials allow electric current to pass through them. These are called conductors. Copper, iron, and aluminum are examples of such conductors. Wires made from these materials are used to transmit electricity from power plants to other places.

But during transmission, these materials heat up and resist the flow of electricity. As a result, about half of the electricity is wasted. In other words, of all the electricity generated in a power plant, only half is actually used, while the other half is lost.

In 1911, Dutch scientist Heike Kamerlingh Onnes (1853–1926) discovered that certain materials, at a specific temperature, reach the point of absolute zero. At that stage, they completely lose their resistance and can transmit electricity without any obstruction. Such materials are called superconductors, and the phenomenon is called superconductivity. Research began on this, and after nearly 80 years, it has reached its final stage. It is now possible to use superconductors for electricity transmission, which means that 100 percent of the generated electricity can be used. In other words, usable electricity can be doubled without building more power plants. This new discovery has made an old saying into reality:

Electricity saved is electricity generated.

This is one example that shows saving is also a kind of income. If you cannot increase your earnings, then reduce your spending. By cutting expenses, you can increase your effective income. This way of adding to income is something every person can put into practice.
