It’s easy to take electricity for granted. The modern life would not be possible without it. To keep it going, we make more efficient ways to manage electricity. This is the smart grid, explained by common craft.

For over 100 years, coal and other fusel fuels have been used by power plants to produce the electricity we use every day. The grid is the network of power lines and substations that carry on electricity from power plants to homes and businesses. Today, the grid has problems. It needs updating and is running at capacity. When power lines break or power plants can’t produce enough power, blackout can occur. And that’s a problem that can cause fatalities. At the same time, today’s grid often relies on a single power source and doesn’t provide detail information on usage, making electricity difficult to manage. To address this problem in the past, we simply build new power plants.

But now, we can work towards stability and reduce our dependence on fusel fuels by using a smarter grid. Here is how.

The smart grid means adding sensors and software to the existing grid that would give utilities and individuals new information that would help them understand and react to changes quickly. Let’s say a tree falls on a power line and 100 homes lose power.
With the current grid, utility employees often physically reroute power, which takes time. With the smart grid, sensors and software would detect and immediately route the power around the problem, limiting issue to few homes.

And there is more. The price of the electricity changes throughout the day. But we can’t see it with the current meters on our homes. It may be expensive during the peak hours and cheap late at night. With a new smart meter at your home, you can set your dishwasher to run when power is cheap. This provides more control of your energy bill, and helps prevent blackouts at peak hours.

The smart grid also means new ways to use renewable energy. Power generation can now be distributed across multiple sources, so the system is more stable and efficient. It’s disability to communicate and manage electricity that makes the grid smarter, and helps us avoid burning more fusel fuels in the future. The smart grid is still a few years away. But soon we will be able to manage our energy bill, help the environment and help the economy by making more informed decisions about how we use electricity.
