The world solely dense on fossil fuels. In 2011 fossil fuels accounted for approximate 82 percent of the worlds primary energy use.

Radio in the united states was to provide knowledge or communication to the citizens of what was going on in the country/ world. They were like tv's now days everyone had one, they gave the news just like television without the images, just the verbiage. For example, during world war 2, FDR (Franklin d. Roosevelt ) had sit-downs known as fireside chats were he would address the American people on the radio about details of the war, he used these talks to keep up the support of the American people and give them some insight to what was going on.
