Document Summary
33geog 3ee3 lecture 4 forms of energy: forms of energy and their significance knowing the differences allows us to determine: the advantages and disadvantages of different forms. Potential energy energy that could be put to work: potential and kinetic energy. Potential energy is determined by: force applied to an object the distance of the movement: e. g. gravitational potential energy. Higher pump up water, more energy, and once energy is released, it activates a turbine and the wheel creates energy. Potential energy and pumped storage at night: power plant produces a surplus of energy. Used to pump water into a high reservoir i. e. power plant water will be released to activate turbines. When demand increases: released to generate energy. Wind energy -> air has mass: carries energy as it moves rate of delivery is determined by wind speed span of blades, orientation, size, etc. are important to see how much energy these will produce.
