8. ENERGY: uses of energy

Most of the energy we use is electric but we consume more than the one we can produce. That great consume of energy produces acid rain, contamination and global warming

Global warning: the atmosphere keeps the Earth at a specific temperature. Contamination destroys the atmosphere keeping the thermal energy inside and the Earth warms up.

      
Energy is used for the houses (warm up water, heating, light...), for science (industries and factories), for medical advances (X-ray, microscopes...), transports, communication and technology (television, radio, internet ,computers, mobile phones...)
