Dear  6C,

Here is a good video that encourages all to turn to Renewable Energy Sources.

It is an american-made video which has relevance to all other countries who need to play a part in saving our Earth.

This is another video that explains the urgency of turning to alternative sources of energy based on Germany as an example.

Here is a video that explains briefly the different types of renewable energy sources we have developed to date.

Video to explain Crooke's Radiometer and Black Body Radiation.
Enjoy!
