 * __PDHPE Questions__**

Is war financially viable for the USA? What are the relative costs of alternative energy sources (eg wind, solar, tidal, nuclear and natural gas)? Examine the costs, availability and constraints. How has global warming been tracked? Examine and interpret the statistics and graphs that have been used to draw conclusions about global warming. What is the energy output of typical air conditioning units? Use local climate statistics to determine the typical number of days air conditioning units would be switched on and therefore the total annual energy consumption and cost. How does the use of different vehicles affect pollution levels? Compare vehicle fuel consumptions (include diesel and LPG as well as petrol driven cars). Consider in your calculations the cost of each vehicle and use different annual travel distances (eg 15,000 km or 25,000 km). Also, consider how a variation of the cost of a particular fuel can change which vehicle is most efficient (eg what happens if the price of diesel fuel was reduced). How effective are plantations in reducing carbon dioxide? Compare the levels of carbon dioxide removed by plantations with the amount of carbon dioxide generated by industry and transport.
