How are crayola crayons environmentally friendly?

Crayola Crayons are Environmentally friendly.

Did you know that solar panels provide energy to produce one billion crayons and half a billion markers each year?

A new tree is planted for every one used to make our coloured  pencils.


Using recycled plastic in our products keeps hundreds or tons of plastic out of landfills each year.

Many Types of Energy



Water Power
  • Moving water produces energy
  • Moving water is a source of clean renewable energy and a reliable energy source which converts kinetic energy from falling water into electricity
  • It is the oldest method by which renewable energy has been harnessed by the human race 
  • I saw a miniature dam by Mud Bay 
Fossil Fuels
  • Fossil fuels such as coal, oil and gas come from the ground and can be turend into energy
  • They are a non-renewable source of energy


Nuclear Power
  • Nuclear energy is a clean, safe way to make electricity. It does not burn any fuel like coal so there are no pollutants released into the air.
  • It uses however, a fossil fuel, uranium.

Wind Power
  • Turbines create electricity from wind.
  • It is a renewable form of energy because we never run out of wind.
  • The windmill was the first form of technology. 
  • Wind is a source of clean renewable energy
  • Scientists use wind tunnels to learn what shapes move fastest.
            

Solar Power 
  • most solar power comes from the sun 
  • poor countries use solar panels
  • solar panels on the roof provide heat and hot water
  • satellites use solar power panels for power.
