Farmers since the ancient Greeks have used water wheels to grind wheat into flour. In the late 19th century, hydropower became a source for generating electricity. The first hydroelectric power plant was built at Niagara Falls in 1879.]]> 2016-07-12 00:12:06 UTC https://padlet.com/tayhay00/a7wdujkaurwi/wish/116232660 tayhay00 https://padlet.com/tayhay00/a7wdujkaurwi/wish/116232763 Hydroelectric power provides almost one-fifth of the world's electricity. China, Canada, Brazil, the United States, and Russia were the five largest producers of hydropower in 2004. One of the world's largest hydro plants is at Three Gorges on China's Yangtze River. ]]> 2016-07-12 00:13:44 UTC https://padlet.com/tayhay00/a7wdujkaurwi/wish/116232763 tayhay00 https://padlet.com/tayhay00/a7wdujkaurwi/wish/116232808 2016-07-12 00:14:49 UTC https://padlet.com/tayhay00/a7wdujkaurwi/wish/116232808 tayhay00 https://padlet.com/tayhay00/a7wdujkaurwi/wish/116232860 Damming rivers may destroy or disrupt wildlife and other natural resources. Some fish, like salmon, may be prevented from swimming upstream to spawn. Technologies like fish ladders help salmon go up over dams and enter upstream spawning areas, but the presence of hydroelectric dams changes their migration patterns and hurts fish populations. Hydropower plants can also cause low dissolved oxygen levels in the water, which is harmful to river habitats.]]> 2016-07-12 00:16:04 UTC https://padlet.com/tayhay00/a7wdujkaurwi/wish/116232860 tayhay00 https://padlet.com/tayhay00/a7wdujkaurwi/wish/116232902 Hydropower is the cheapest way to generate electricity today. That's because once a dam has been built and the equipment installed, the energy source—flowing water—is free. It's a clean fuel source that is renewable yearly by snow and rainfall.Hydropower is also readily available; engineers can control the flow of water through the turbines to produce electricity on demand.]]> 2016-07-12 00:16:53 UTC https://padlet.com/tayhay00/a7wdujkaurwi/wish/116232902 tayhay00 https://padlet.com/tayhay00/a7wdujkaurwi/wish/116233025 About half of all alternative energy used in the United States comes from hyrdo electric power. Hydroelectric stations exist in at least 34 US states, including North Carolina. The biggest hydro plant in the United States is located at the Grand Coulee Dam on the Columbia River in northern Washington.]]> 2016-07-12 00:19:40 UTC https://padlet.com/tayhay00/a7wdujkaurwi/wish/116233025 tayhay00 https://padlet.com/tayhay00/a7wdujkaurwi/wish/116233130 2016-07-12 00:21:27 UTC https://padlet.com/tayhay00/a7wdujkaurwi/wish/116233130 tayhay00 https://padlet.com/tayhay00/a7wdujkaurwi/wish/116234520 Sadly, my county does not use a lot of alternative energy. There are a few locations on the map below (from eia.gov) that indicate solar power, biomass, and nuclear power plants.]]> 2016-07-12 00:44:04 UTC https://padlet.com/tayhay00/a7wdujkaurwi/wish/116234520
