Energy resources
Core • Distinguish between renewable and nonrenewable sources of energy • Describe how electricity or other useful forms of energy may be obtained from: – – – – chemical energy stored in fuel water, including the energy stored in waves, in tides, and in water behind hydroelectric dams geothermal resources nuclear fission heat and light from the Sun (solar cells and panels) • Give advantages and disadvantages of each method in terms of cost, reliability, scale and environmental impact • Show a qualitative understanding of efficiency
Supplement • Show an understanding that energy is released by nuclear fusion in the Sun • Recall and use the equation: • efficiency = useful energy output/energy input × 100%
Resources • Use p 90 -93 to make a table of 9 resources • Include a column each for – A brief description of the resource – Is it from the sun? – cost, reliability, scale (how much energy can it produce), and environmental impact
