Document Summary
Hydropower, nu(cid:272)lear, a(cid:374)d (cid:271)io(cid:373)ass are (cid:858)(cid:859)(cid:272)o(cid:374)(cid:448)e(cid:374)tio(cid:374)al(cid:859)(cid:859) and non-renewable energy alternatives. Fuelwood and other biomass sources provide a(cid:271)out (cid:1005)(cid:1004)% of the (cid:449)o(cid:396)ld(cid:859)s e(cid:374)e(cid:396)g(cid:455), nuclear power; about 6. 3% and hydropower; about 2. 2% Nuclear energy and hydro each account for nearly one-si(cid:454)th of the (cid:449)o(cid:396)ld(cid:859)s electricity generation. Canada relies heavily in hydroelectric power generation. Hydroelectric power uses the kinetic energy of moving water to turn turbines and generate electricity. Approaches (first is much more common): (1) dams harness kinetic energy by storing water in reservoirs (cid:858)(cid:859)i(cid:373)pou(cid:374)d(cid:373)e(cid:374)t(cid:859)(cid:859) approach (2) run-of-river generates energy without greatly disrupting the flow of river water. Not disrupting the flow as much as process 1. (1)impoundment approach. Large dams funnel water to rotate turbines. As water flows out, it will rotate the turbines, which will generate electricity. Becoming more favorable because it has less impact on aquatic system. Basically, they have water run through the intake pipe, that rotates the turbines, and that water goes back into the river.
