The total power used by humans worldwide is approximately 15 TW (terawatts). Sunlight striking Earth provides 1.336 kW per square meter (assuming no clouds). The surface area of Earth is approximately 197,000,000 square miles. How much of Earth's surface would we need to cover with solar energy collectors to power the planet for use by all humans? Assume that the solar energy collectors can only convert 10 % of the available sunlight into useful power.

The best solar panels currently available are about 15% efficient in converting sunlight to electricity. A typical home will use about 40. kWh of electricity per day (1 kWh = 1 kilowatt hour; 1kW = 1000 J/s). Assuming 8.0 hours of useful sunlight per day, calculate the minimum solar panel surface area necessary to provide all of a typical homes electricity. (See Exercise 124 for the energy rate supplied by the sun.)
Explain why hydroelectric power and wind power are indirect forms of solar energy.
Define the terms renewable and nonrenewable as applied to energy resources. Which of the following energy resources are renewable: solar energy, coal, natural gas, geothermal energy, wind power?
Fossil fuel, nuclear, and hydroelectric power plants all require a transmission network to transport electricity from where it is generated to where it is used. MCFCs, with their smaller size and portability, can be placed much closer to where the power is needed, reducing the need for transmission lines. With this in mind, explain why MCFCs may have a greater advantage for providing power in developing countries versus in developed countries.
Which of the following is a renewable energy resource? (a) nuclear fusion (b) hydroelectric power (c) natural gas (d) coal
Some solar-heated homes use large beds of rocks to store heat. (a) How much heat is absorbed by 100.0 kg of rocks if their temperature increases by 12C? (Assume that c=0.82J/gC.) (b) Assume that the rock pile has total surface area 2 m2. At maximum intensity near the earth's surface, solar power is about 170 watts/m2. (1watt=1J/s.) How many minutes will it take for solar power to produce the 12C increase in part (a)?
A number of companies currently lease solar panels to homeowners to offset the home’s energy use. The total energy production of a certain residential solar system in suburban Maryland was 7581.62 kWh over the last calendar year. What mass of carbon dioxide did this solar system keep out of the atmosphere during that time, assuming that the energy consumed by this home would otherwise have been supplied solely by coal-burning power plants (note that this isn’t a great assumption, as Maryland also has a nuclear power plant, solar and wind farms, and Montgomery County incinerates waste to generate electricity)? Keep in mind that power plants are inefficient, and are able to convert on average 33% of the heat generated by the combustion of coal into electricity. Assume that coal can be approximated as C(s) (again, not a great assumption, but sufficient for this problem). Use the following data to find the heat of combustion of coal: 2 C(s) + O2(g) ----> 2 CO(g).…

The total rate at which power is used by humans worldwideis approximately 15 TW (terawatts). The solar flux averagedover the sunlit half of Earth is 680 W/m2 (assumingno clouds). The area of Earth’s disc as seen from the Sun is1.28 x 1014 m2. The surface area of Earth is approximately197,000,000 square miles. How much of Earth’s surfacewould we need to cover with solar energy collectors to powerthe planet for use by all humans? Assume that the solar energycollectors can convert only 10% of the available sunlightinto useful power.
Consider a cloudless day on which the sun shines down across the United States. If 2667 kJ of energy reaches a square meter (m2) of the United States in one hour, how much total solar energy reaches the entire United States per hour? The entire area of the United States is 9,158,960 km2.
