Estimate how many large maple trees would be needed to run a dishwasher for one year. Assume the dishwasher uses
1.1 x10 J of energy per year and a large maple tree captures 10 kg of carbon (in CO2) per year. Assume the power
plant that generates the electricity is 35 % efficient at converting the carbon in coal to electrical energy and that typical
coal releases 40,000 kg of carbon (as CO2) per terajoule of energy when burned.

- (a) Calculate the power per square meter reaching Earth's upper atmosphere from the Sun. (Take the power output of the Sun to be 4.001026 W.) (b) Part of this is absorbed and reflected by the atmosphere, so that a maximum of 1.30 kW/m2 reaches Earth's surface. Calculate the area in km 2 of solar energy collectors needed to replace an electric power plant that generates 750 MW if the collectors convert an average of 2.00% of the maximum power into electricity. (This small conversion efficiency is due to the devices themselves, and the fact that the sun is directly overhead only briefly.) With the same assumptions, what area would be needed to meet the United States' energy needs (1.051020J) ? Australia's energy needs (5.41018J) ? China's energy needs (6.31019J) ?

- 5. How many Joules of energy is in one kilowatt hour? Our classroom has about 20 lights, each with 50 W power rating. How many hours could a generator operating at 100% efficiency supply this power from one gallon of gasoline? If the generator operated at a realistic efficiency of 20%?arrow_forwardThe United States has a lot of federally owned land. Unfortunately, uncontrolled natural forest fires destroy large areas in the western US every summer. In 2002, about 1,000,000 acres of standing timber in national forests were consumed. Some consideration is being given to improved management practices that could produce electric power from residual forest thinning. Estimate the lost energy content of burned US forests during 2002. Assuming the US average electricity demand is about 300,000 MWe, how much forested land would be needed to produce all the country's power? Is this a sustainable alternative? How would you manage the forest lands needed? A few facts to consider: • The total forested area on US federal lands in the lower 48 states is about 600 million acres with a standing stock density of about 100 dry metric tonnes of wood per acre, • ● Woody plants and trees capture solar energy via photosynthesis at an average rate of about 0.8 W/m2 which corresponds to producing about…arrow_forward2.

Assume human power consumption is 15 TW. If one takes into account the day-night cycle and occasional cloudiness, solar panels receive on average about 200W/m2 of sunlight. And this is further reduced because those panels convert sunlight into electricity with an efficiency of about 20%.arrow_forward
