19:24 Energy resources: 14.1 INRODUCTION: Energy  provides the capacity to do work, to cause something to happen, or to  cause change in a system Energy resource:  something that can be used to: Produce heat Produce electricity Move vehicles Matter that stores energy in a reusable form is also called  fuel. In the U.S today, the average person uses 110 times the amount of energy used  by a prehistoric hunter-gatherer. Most energy for human consumption in the industrial world comes from oil  and natural gas List of energy resources: Coal Wind Flowing water Nuclear energy Geothermal energy Solar energy Oil, gas, coal, and fuel come from rocks Fossil fuels:  consumable material derived from organisms that lived in the past 14.2 SOURCES ON ENERGY IN THE EARTH SYSTEM There are five fundamental sources of energy on the Earth

Energy generated by nuclear fusion in the Sun and transported to the  Earth via electromagnetic radiation Energy generated by the pull of gravity Energy generated by nuclear fission reactions Energy that has been stored in the interior of the Earth Energy stored in the chemical bonds of compound Different ways these forms of energy become resources we can use Energy from the sun  --- results from nuclear fusions within the sun --- can be  converted directly into electricity by using solar panels, or can be used to heat  or warm a house Energy from gravity  --- gravitation attraction of the moon causes ocean tides  --- this flow of water in and out of channels during tidal changes can drive  turbines Energy from both sun and gravity  --- solar radiation heats the air – it rises –  gravity causes cooler air to sink – the resulting air movement is wind, which  powers sails and windmills Energy from photosynthesis  --- the chlorophyll stores potential energy ---
