 Solar panels- point to sun  Is capable of producing heat, causing chemical reactions or generating electricity  Flat plate collector – solar heating device  Absorbs lot of heat  Source of energy for photosynthesis

 Hydro electricity- Renewable energy  Renewable because of water cycle  Hydro electric wheel- oldest energy machine

 Nuclear energy- atom.  Uranium (U) : big silvery stone  Energy- clean  Nuclear power plants- cylinder electricity

Uranium  It is malleable ( pounded -thin sheet)  It is ductile (stretch)  Dense and heavy  13% energy in the world- nuclear power plants  No pollution with nuclear energy- clean

 Used to grind grains and pump water  Developed in mid 1800s  Negative environmental impacts – Loud noise, disturbance  Wind turbines do the exact opposite of a fan- They use wind to generate electricity

 Coal energy- not clean  Coal Miners- Get diseases- Pneumonoultramicroscopicsilicovolca noconiosis!  Causes pollution
