it is easy to take electricity for granted.but modern life would not be possible without it.to keep it  going,wo need to more efficient ways to manage electricity.this is the smart grid,explained by common craft.for over 100 years,coal and other fossil fuel have been used by power plants to produce the electricity we use every day.the grid is the net work of power lines and substations that carry electricity from power plants to homes and bussinesses.today the grid has problems it needs updating and is running out of capacity.when power lines break or power plants can not produce enough power,blackout can occur.this is the problem that can cause fertilities.at the same time ,today's grid often relies on a single power source and doesn't provide detail information on usage,making electrity difficult to manage.to address these problems inthe past,we simply build new power plants.now wo can work towards stability and reduce our dependance of fossil fuels by using a smart grid.here's how.the SG means acting sensors and software to the existing grid that would give utilities and individuals new information that would help them underatand and react to change quickly.let's say a tree falls on a  power line.and 1000 of homes lose power.it takes time.with smart grid,sensors and software       would detect and  immediately route the power around the problems ,limiting issue to few homes.and there is more,    the price of e changes throughout the day.we cant see it with the current meters on our home. it may be expensive during the peak hours    and cheap late at night .with the new smart gird on your home,you can set your dishwasher to run when   power is cheap.  this provides more controls of your energy bill  and help provent  blackout 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 is disability to communicate and manage the e  that makes the grid smart.   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.
