C SOLAR ENERGY CHEMICAL ENERGY KINETIC ENERGY M Y CM MY WHAT DO WE USE ENERGY FOR? *US, 2012 CY CMY Energy comes from many sources. We use it—in all its different K forms—to make our lives easier and better. BUSINESS: heating, cooling, and lighting for buildings where people work 19% INDUSTRY: energy for making, 31% extracting, and refining things—like metals, wood, plastics, and glass TRANSPORTATION: fuel for vehicles of all kinds 22% HOMES: heating, cooling, and lighting for buildings 28% where people live INTRODUCTION TO ENERGY 2 3.pdf 1 2014-11-10 6:28 PM WHERE DOES ENERGY COME FROM SOLAR WIND NUCLEAR The sun produces a Wind comes from heat Nuclear energy comes huge amount of light and pressure changes from the power of atoms— and heat energy, only that occur when the sun tiny pieces of matter.

But if you look back far enough, you’ll see that most of it originally came from the power of the sun. 1 2 C M 3 Y CM MY CY CMY K OIL COAL NATURAL GAS 1 Most of the energy that powers our vehicles and supplies our electricity comes from fossil fuels. Millions of years ago, even before dinosaurs, these fuels were living things—ancient plants and animals fed by energy from the sun’s rays. 2 When these living things died, they were buried under layers of mud, sand, and rock. Heat, pressure, and bacteria helped them decompose. The sun’s energy, stored inside them, became more and more concentrated. 3 Eventually, they were converted into oil (a thick black liquid, also called petroleum), coal (a black rock), and natural gas (a clear gas).
