If 10% of your state would be covered with PV collectors, estimate the power produced in kWh/day per capita on average. If 10% of the people in your state had to drive 100 km/day to commute to work, how many kWh/day would that consume? Discuss the implications of these two estimates. How many collectors of 3 m × 10 m would be required to produce the energy for commuting with an all-electric car with 60% efficient batteries?
