This free infobook for Grades 6-8 provides an overview of energy sources, with special focus on the transformations necessary to convert energy into usable fuels for consumption. It takes a look at biomass, fossil fuels, hydropower, geothermal, solar, wind, and nuclear energy in a context of environmental concerns and climate change. Each chapter goes into detail on the discovery and production of each resource, environmental impacts, costs to process and transport, and availability for consumption. High-quality reproducible graphics accompany all segments, providing illustrations of power plants, extraction, mining, electricity generation, and country-by-country fuel usage. The sequence is part of the NEED K-12 curriculum, in which energy forms are extensively studied in the elementary grades to build foundations for understanding the physics behind energy transformations and the Law of Conservation of Energy.
The NEED Project is a national initiative to bring innovative curriculum materials in energy education to teachers and learners from the primary grades through college.
Editor's Note:Confusing energy forms and energy sources is a documented roadblock to future understanding of energy as a physics concept. Often, students enter high school believing that "fuel" is synonymous with "energy" and that the Law of Conservation of Energy means turning down the thermostat to use less fuel. The NEED project's free Infobooks introduce energy forms first -- in elementary school -- then delve into fuels/energy sources in middle school. The high school Infobook explores energy transfer in systems and quantitative calculations of energy flow.

4. The Physical Setting
4B. The Earth
6-8: 4B/M3. Everything on or anywhere near the earth is pulled toward the earth's center by gravitational force.
6-8: 4B/M7. Water evaporates from the surface of the earth, rises and cools, condenses into rain or snow, and falls again to the surface. The water falling on land collects in rivers and lakes, soil, and porous layers of rock, and much of it flows back into the oceans. The cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on Earth.
6-8: 4B/M10ab. Some material resources are very rare and some exist in great quantities. The ability to obtain and process resources depends on where they are located and the form they are in. As resources are depleted, they may become more difficult to obtain.
4E. Energy Transformations
6-8: 4E/M1. Whenever energy appears in one place, it must have disappeared from another. Whenever energy is lost from somewhere, it must have gone somewhere else. Sometimes when energy appears to be lost, it actually has been transferred to a system that is so large that the effect of the transferred energy is imperceptible.
6-8: 4E/M2. Energy can be transferred from one system to another (or from a system to its environment) in different ways: 1) thermally, when a warmer object is in contact with a cooler one; 2) mechanically, when two objects push or pull on each other over a distance; 3) electrically, when an electrical source such as a battery or generator is connected in a complete circuit to an electrical device; or 4) by electromagnetic waves.
6-8: 4E/M3. Thermal energy is transferred through a material by the collisions of atoms within the material. Over time, the thermal energy tends to spread out through a material and from one material to another if they are in contact. Thermal energy can also be transferred by means of currents in air, water, or other fluids. In addition, some thermal energy in all materials is transformed into light energy and radiated into the environment by electromagnetic waves; that light energy can be transformed back into thermal energy when the electromagnetic waves strike another material. As a result, a material tends to cool down unless some other form of energy is converted to thermal energy in the material.
6-8: 4E/M4. Energy appears in different forms and can be transformed within a system. Motion energy is associated with the speed of an object. Thermal energy is associated with the temperature of an object. Gravitational energy is associated with the height of an object above a reference point. Elastic energy is associated with the stretching or compressing of an elastic object. Chemical energy is associated with the composition of a substance. Electrical energy is associated with an electric current in a circuit. Light energy is associated with the frequency of electromagnetic waves.
6-8: 4E/M6. Light and other electromagnetic waves can warm objects. How much an object's temperature increases depends on how intense the light striking its surface is, how long the light shines on the object, and how much of the light is absorbed.
9-12: 4E/H1. Although the various forms of energy appear very different, each can be measured in a way that makes it possible to keep track of how much of one form is converted into another. Whenever the amount of energy in one place diminishes, the amount in other places or forms increases by the same amount.
3-5: 4F/E3. Light travels and tends to maintain its direction of motion until it interacts with an object or material. Light can be absorbed, redirected, bounced back, or allowed to pass through.
4G. Forces of Nature
6-8: 4G/M3. Electric currents and magnets can exert a force on each other.
6-8: 4G/M4. Electrical circuits require a complete loop through which an electrical current can pass.
6-8: 4G/M5. A charged object can be charged in one of two ways, which we call either positively charged or negatively charged. Two objects that are charged in the same manner exert a force of repulsion on each other, while oppositely charged objects exert a force of attraction on each other.
7. Human Society
7G. Global Interdependence
6-8: 7G/M5. The global environment is affected by national and international policies and practices relating to energy use, waste disposal, ecological management, manufacturing, and population.
8. The Designed World
8C. Energy Sources and Use
6-8: 8C/M3. In many instances, manufacturing and other technological activities are performed at a site close to an energy resource. Some forms of energy are transported easily, others are not.
6-8: 8C/M4. Electrical energy can be generated from a variety of energy resources and can be transformed into almost any other form of energy. Electric circuits are used to distribute energy quickly and conveniently to distant locations.
6-8: 8C/M5. Energy from the sun (and the wind and water energy derived from it) is available indefinitely. Because the transfer of energy from these resources is weak and variable, systems are needed to collect and concentrate the energy.
6-8: 8C/M6. Industry, transportation, urban development, agriculture, and most other human activities are closely tied to the amount and kind of energy available. People in different parts of the world have different amounts and kinds of energy resources to use and use them for different purposes.
6-8: 8C/M8. People have invented ingenious ways of deliberately bringing about energy transformations that are useful to them.
6-8: 8C/M9. Energy resources are more useful if they are concentrated and easy to transport.
6-8: 8C/M10. Some resources are not renewable or renew very slowly. Fuels already accumulated in the earth, for instance, will become more difficult to obtain as the most readily available resources run out. How long the resources will last, however, is difficult to predict. The ultimate limit may be the prohibitive cost of obtaining them.
6-8: 8C/M11. By burning fuels, people are releasing large amounts of carbon dioxide into the atmosphere and transforming chemical energy into thermal energy which spreads throughout the environment.
