imported from other states. Imports account for more than 80% of total energy consumption‚ including all of Idaho’s natural gas and petroleum supplies and more than half of its electricity. Of the electricity consumed in Idaho in 2005‚ 48% came from hydroelectricity‚ 42% was generated by burning coal and 9% was generated by burning natural gas. The remainder came from other renewable sources such as wind. In addition‚ Idaho also has the 6th fastest growing population in the United States with the population

Static electricity: electric charge that builds up on the surface of an object Friction: is the force resisting the relative motion of two surfaces in contact When two objects are rubbed together there is more contact between the surfaces and so more electrons are transferred Electron Affinity: Electron affinity is the tendency of a substance to hold onto electrons. Items high on the list (electrostatic/ triboelectric series) will tend to lose electrons easily (positive) Items low on the list

streams. Dams generally serve the primary purpose of retaining water‚ while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. Hydropower and pumped-storage hydroelectricity are often used in conjunction with dams to generate electricity. A dam can also be used to collect water or for storage of water which can be evenly distributed between locations. TYPES OF DAMS:

Fossil Fuels which include Petroleum and Natural Gas were formed million years ago from the remains of plants and animals‚ are responsible 40% and 20% respectively for the world ’s energy. They were first discovered about 700-900 years ago‚ however since the first modern petroleum industry began in 1859‚ the demand for fossil fuels has escalated beyond our control. It had taken 50-300 million years to form‚ and yet we have managed to burn roughly half of all global oil reserves in merely 125 years

Drainage: • The term “drainage” describes the river system of an area. • The area drained by a single river system is called a “drainage basin” or river basin. • Any higher ground‚ such as mountain or upland separates two adjoining drainage basins. Such upland is known as a water divide or a watershed. • Depending upon the relief‚ geological structure and climatic conditions of the area‚ the streams form different patterns. Drainage Pattern: • Drainage of an area is concerned with the study

Another cause of deforestation in Canada is urban development‚ as population increases more land is needed to provide homes for families‚ which makes up 19 percent. The other important causes of deforestation are forest roads and hydroelectricity which make up 10 percent each ("Deforestation in Canada—What Are the Facts?"). Many countries build roads into remote areas to improve the transportation of goods and provide entry into lands that were not accessible

in those early days it seemed that there was a system to divert water from the natural pathways to dams or for irrigation purposes. Sometimes the water from dams is exploited for communities with various other purposes; like the creation of hydroelectricity‚ flood control‚ sediment control‚ navigation‚ and water supply. (Mining Water) Although the building of dams did not start in the United States until the 1930’s
