Energy comes from a Power Source. There are many types of power sources, but most energy we use today comes from an energy source known as "fossil fuels." Coal, crude oil, and natural gas are fossil fuels. These substances were formed when ancient plants and animals, like the dinosaurs, died. As their bodies decayed they were mixed with the sand and mud and buried deep in the earth. Compression and heat over millions of years changed them into substances that we can burn as fuel.
Let's take a look at the types of power sources that are used:
Sun Power (solar energy) gives us heat and light energy. The sun makes energy from nuclear fusion. Hydrogen atoms collide with each other billions of times each second and produce helium. Every second, 4.7 million tons of hydrogen become energy.
Solar photovoltaic cells use sunlight to produce electricity that can be used directly or stored in batteries for later use.
Nuclear Power is used to make electricity. Inside a nuclear reactor, atoms from a fuel called uranium are split by neutrons (nuclear fission). This energy is released as heat, which changes water into steam, which then turns turbine generators.
Wind Power is used for mechanical and electrical energy. Wind has been used for thousands of years to help ships sail and turn windmills to pump water for irrigation.
Geothermal is heat energy from deep in the earth that is collected using special pipes buried underground. In some areas of the world, steam is collected and used to turn turbine generators. In other areas, pumps circulate water down several feet below the surface into the always-mild earth temperatures, where the water is cooled in summer and heated in the winter. This water is used in heat pumps to cool and heat homes and buildings and can also provide hot water.
Biomass is energy that comes from plants and organic matter such as wood, crops like corn and sugarcane, manure, aquatic plants. Even landfill gas from garbage and sewage provide a source of fuel that can be burned to release its stored energy to make electricity. Other products from biomass include liquid and gaseous fuels, heat, and other chemicals. Biomass is a "renewable fuel," which helps reduce the use of non-renewable fossil fuels.

Kids Korner is made possible by the creative, talented and dedicated team consisting of the following:
Valerie Williams, Apogee’s Art Director and Lead Artist is the creator and artistic talent behind Kids Korner. In the late 90s, after producing hundreds of illustrations and animations for Apogee online courses and Internet content over the years, it occurred to Valerie that these expensive art elements could be re-purposed for communicating complicated energy concepts to children. Encouraged by the enthusiastic reaction she received from our utility customers, Valerie undertook the design and began the curriculum development of what has become one of the most elaborate and comprehensive energy education sites around. As the site shows, her artistic flair brings technical topics to life, and her proficiency in Photoshop, Quark, In-Design, Illustrator, Flash and Dreamweaver enable her to create impressive designs in both electronic and print formats.
Margaret M. Aderholdt, a middle school teacher at Wellborn Elementary in Anniston, Alabama, leads Apogee’s teacher advisory group. In this capacity, she is the spokesperson for the group, providing input to the curriculum developed for Kids Korner and kid-testing any support materials designed for use with the site prior to them going into production and distributed to customers or schools. With more than 16 years teaching experience, Margaret has been awarded numerous grants and honors for herself and the various schools at which she has instructed. Most recently, she was named the 2004 Teacher of the Year for her outstanding work increasing her student’s test scores, expanding their involvement in academic pursuits, and her tireless efforts to stimulate and challenge her students to higher achievement. Margaret spends her summers attending professional development conferences, workshops, and classes to stay abreast of the latest research in science education. Margaret earned her B.A. in Business Administration at Transylvania University and holds a masters degree in International Commerce from the University of Kentucky. After raising two college age daughters, Margaret returned to the classroom herself to earn a masters degree in Elementary Education.
Michael Overstreet is Apogee’s Kids Korner Product Manager and the mastermind of the site’s programming and navigational design. In his role as product manager, Michael assists utilities with the implementation of their customized Kids Korner application. In addition, he leads Apogee’s field testing of all Kids Korner website activities and supplemental material, conducting classroom trials in local schools.
Susan Gilbert brings to Kids Korner and its growing number of support materials her education and experience as an instructional designer and her enthusiasm for energy education. As president and co-founder of Apogee, Susan is the primary architect behind Apogee’s online energy courses and web content divisions, effectively translating her nearly 25 years of energy efficiency and training experience into highly interactive, online training courseware and Web site tools. Drawing upon her masters degree in Curriculum and Instruction, Susan directs the instructional design process for all Apogee eLearning initiatives, including her personal favorite, Kids Korner.
Dick Niess is Kids Korner’s technical reviewer responsible for assuring accuracy and clarity of the concepts covered on the site. A distinguished Tau Beta Pi graduate of the Virginia Military Institute, Mr. Niess earned his Bachelor of Science degree in Engineering. Mr. Niess is a Fellow of the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), is immediate past Chairman of the Applied Heat Pump and Heat Recovery Technical Committee, and serves on the Geothermal Energy Utilization and Centrifugal Machines Technical Committees. He is a repeat contributor to the ASHRAE Systems Handbook, and has authored numerous technical publications for the energy industry.
