HW
It's easy to take electricity for granted, but modern life would not be possible without it. To keep it going, we need more efficient ways to manage electricity.This is the Smart Grid, explained by Common Craft.
For over 100 years, coal and other fossil fuels had been used by power plants to produce electircity we use everyday. the grid is the network power lines and substations that carry electricity from power plants to homes and businesses.Today the grid has problems, it needs updating and its 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 cuase fatality.At the same time, today's grid  often relies on single power source, and dosen't provide detailed 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 sustainability,and reduce our dependable fossil fuels by using a smarter grid.
Here is how. The smart grid means adding censors and software to the existing grid that would give utilities and individuals new information what helps them understand and react to changes quickly. Let's say a tree falls on power line, and one thousnd homes lose power. With the current grid, utility employees often physically reroud power which takes time.With the smart grid, censors and software would  detact and immediately roud the power around the problem, limiting the issues to fewer home. And there's  more,the price of electricity changes throughout the day, but we can see it with the current meters on our homes. it may be expensive during the peak hours and cheap late at night. with new smart meter at your home, you can set your dishe washer to run when power is cheap; this provides more control on your energy bill and helps to prevent blackout at peak hours.The smart grid also means new ways to use renewable energy. Power generation can now be distributed across mutiple sources , so the system is more stable and efficient. This is ability to communicate and manage electricity that makes the  grid smarter. and helps us avoid burning more fossil fuels in the future.
The smart grid is still a few years away, but soon we'll be able to manage our energy bill , healthy environment and healthy economy by making  more form decisions about how we use electricity.
