-Fossil fuels: Fuels that are formed by the decomposition of buried organic material, and exposure to heat ad pressure, producing substances such as coal, oil and gas.
-Industry: Any economic activity that produces a service or transforms raw materials into consumer goods.

-Solar panel: is a set of solar photovoltaic electrically connected and mounted on a supporting structure.
.Renewable energy: is generally defined as energy that comes from resources which are naturally replenished on a human timescale.
-Non-renewable energy: is a resource that does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human-frames.
-Traditional energy: Refers to the energy sources that are most commonly used, such as oil.
-Alternative energy: refers to sources that are still being developed, such as solar energy.
-Dam: is a barrier that impounds water or underground streams.

Microphone

This invention was created by Emilie Berliner in 1876. It was made because some chemists wanted to discover how to make a lauder sound and for record. In 1964, James West and Gerhard Sessler invented one of this, but it was more confortable and not too heavy. Today, this machine is used in many situations like in concerts or in parties. There are many types of it.
