15.    A friend is adamantly against building any more nuclear power plants in your local area. You, however, understand its benefits. How might you address your friend to convince him of the need for the new power facility?

Calculate the electric energy requirement when all the vehicles are electrified. Pick an industry, location, or use of transportation. Calculate its current (ICE) energy usage. (either by total fuel consumption or total distance traveled) Calculate its projected (EV) energy usage. Calculate and add the price and growth effects.

2. A Boeing 747 weighs 200 metric tons and uses about 5 million MJ on an international 10-hour flight. If this energy were supplied by lithium-ion batteries with an energy density of 0.25 kWh per kilogram, how much would the batteries add to the weight of the airplane? Express your answer in metric tons.

5. The resistance of a certain circular conductor is 7 ohms. It is drawn so that its new length is thrice the original length. What is the new resistance?

1) A power plant's marginal fuel cost is the rate of shift in fuel cost relative to produced power. (Is that true or false?)

The 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…

A region gets its electric supply from a nearby coal power plant. Some people in the region install solar panels on their roofs to generate electricity. Factors about both electricity generated from coal and solar are listed in a table. Cost for Cost to How Origin of House to Begin Electricity Use Pollution Electricity is Delivered Reliability System/ Month Events Service wires continually burning coal to produce electricity attaching interrupted only by short- coal $0 $122 house to electrical term events grid initially producing and installing large panels attached to weather, and dependent on time of day, solar $20,000 $0 the solar roof seasons panels Which is an advantage of electricity generated from solar panels compared to coal? O Solar panels provide electricity using large panels. O Solar panels provide electricity reliably throughout the year. O Solar panels provide electricity without any cost to the home.
