a. solar panels
b. hydroelectricity
c. wind turbines
d. coal

Explanation:

For the first question:

• Option A: Running electric heaters in each room instead of central heat is less energy - efficient as central systems can be more optimized.
• Option B: Burning cardboard indoors is a fire hazard and not a sustainable or safe energy - conservation method.
• Option C: Turning the thermostat down a bit and wearing a sweater is a simple way to conserve energy with minimal impact on daily life.
• Option D: Turning off the heat completely when leaving for vacation is a good energy - saving measure but only relevant during vacations, while option C is a more general - use, low - impact method.

For the second question:

• The town has intense, year - round sunshine and unused flat terrain. Solar panels can utilize the abundant sunlight.
• Hydroelectricity requires water (which is scarce here).
• Wind turbines are not indicated as having a particular advantage based on the given information (no mention of strong winds).
• Coal is a non - sustainable and polluting energy source.

Answer:
