Ways to save power at home and at school:
There are many ways to save power at school and home our group has come up with some ways to save power at school and home here they are:

• Instead of using lights open up the windows and use that instead of an air conditioner and use the suns light.Untitled1.png

• We can turn of light bulb when we are finished with them.
• To save energy we can use instead of Google (white uses up a lot of energy where as black doesn’t really use energy) to search for other websites.•

  • using solar panels to power lights or anything electrical can save you a lot on your electricity bills and can help save the earth from global warming or at this point in time at least help prevent it from getting any worse.

  • Getting your school involved with solar power could help your school become earth friendly and because we use the lights in the class room almost everyday it can help schools with their electricity bills.

Have you ever used a magnifying glass to make something melt or burn? You were using solar power!

“Solar” is the Latin word for “sun” – and it’s a powerful source of energy. In fact, the sunlight that shines on the Earth in just one hour could meet world energy demand for an entire year!
We can use solar power in two different ways: as a heat source, and as an energy source.

People have used the sun as a heat source for thousands of years. Families in ancient Greece built their homes to get the most sunlight during the cold winter months.
In the 1830s, explorer John Herschel used a solar collector to cook food during an adventure in Africa. You can even try this at home!

Today we can use solar collectors for heating water and air in our homes. If you’ve seen a house with big shiny panels on the roof, that family is using solar power.

We can also use solar energy to make electricity. The process is called photovoltaics.

If you have a solar-powered watch or calculator, you’re using photovoltaics!
In 1954, scientists at Bell Telephone discovered that silicon (an element found in sand) created an electric charge when it was exposed to lots of sunlight. Just a few years later, silicon chips were used to help power space satellites.
Today, more than 10,000 American families get all of their electricity from solar power

And silicon from just one ton of sand, used in photovoltaic cells, could produce as much electricity as burning 500,000 tons of coal.

You might be wondering why we don’t use solar electricity all the time. Solar power systems make a different kind of electricity than big power plants do, so different wiring is needed – and that can be expensive.
