PLEASE HELP WILL GIVE 100 POINTS !!!!!!

a. Use the graph above to answer the questions:
i. Identify one country that shows energy use per capita above 20,000 kWh.
ii. Describe one variable that could be contributing to the high energy use of the country identified in (i).
iii. Compare the energy use of a country that uses less than 20,000 kWh per capita with the energy use of the country identified in (i). Describe one possible reason for the observed difference in energy use.

b. There are many ways energy conservation can reduce a country's energy use per capita. The table below shows conversion factors for different types of renewable and non-renewable energy. Use the table to answer the questions:

i. Using green design features is one way of addressing energy conservation. This includes using energy-efficient appliances. Calculate the kilowatt-hour of energy used per year by an average 255-watt washing machine, used three hours a day.
ii. Calculate the amount of energy and money saved by using a more efficient 180-watt washing machine instead of a 255-watt washing machine. Based on energy savings, provide reasoning for using more green design features in homes.
iii. Describe two methods for conserving energy around a home that could reduce energy use per capita for a household.
