Question 3Which distinction separates a primary energy source from an energy carrier?

Renewability defines primary energy; fossil origin defines carriersFuel delivered to users is primary energy; the transmission lines are carriersDomestic production defines primary energy; imported supplies are carriersNatural sources provide primary energy; converted forms serve as carriers

Question 4A sunny region has little grid capacity near a proposed solar site. Which conclusion fits these facts?

Abundant sunlight compensates for the transmission bottleneckTransmission limits restrict delivery despite abundant sunlightLimited grid capacity indicates that the sunlight estimate is too highGeneration potential establishes useful local supply without delivery studies

Question 5What must electricity-grid operators continually coordinate?

Fuel deliveries must match the annual total of electricity useThe nearest generator must supply each customer’s requested powerGeneration must meet demand without exceeding network limitsThe highest-priced generator must send power down the shortest line

Question 6During daylight, a battery stores solar output for evening use. What has changed?

The battery shifts delivery from the time of generation to the time of demandThe battery has increased the amount of primary energy availableThe system converts a larger fraction of sunlight into electricityThe battery transfers electricity without adding conversion losses

Question 7A clinic has a grid connection but frequent long outages. What does this reveal about energy access?

Connection statistics establish adequate service despite the interruptionsA physical connection without dependable service leaves access inadequateFrequent outages demonstrate a surplus relative to the clinic’s needsAppliance ratings provide a sufficient measure of the power available for use

Question 8Why might a strong wind resource remain difficult to develop?

High average wind speed is enough to establish a financially workable siteResource quality determines the priority of a project’s land rightsA site’s rated generation capacity indicates how much power users can receiveDevelopment depends on feasible access and permission to use the site

Question 9National data suggest high electricity access. Why examine remote communities separately?

The national figure represents the service a typical remote household receivesThe national comparison becomes invalid if communities differA national summary does not establish local reliability or affordabilityRemote settlements are usually outside the scope of national access measures

Question 10What does a capacity factor measure?

Actual energy relative to continuous full-power productionConversion efficiency between input energy and useful outputHousehold connection coverage across the electricity networkRecoverable construction materials as a fraction of the plant’s total mass
