why has society been developing different renewable forms of energy in the past few decades?
write 2 - 3 complete sentences.

Explanation:

• For question 10: Turning off heat/air systems and unplugging electrical items when the office is closed is a practical way to reduce energy use without major disruptions to employees. Removing half the light bulbs and having employees use flashlights would be inconvenient. Replacing a microwave with a charcoal grill is not practical for an office. Going paperless on just Tuesdays is a minimal effort.
• For question 11: Using public transportation reduces individual vehicle energy use. Developing more efficient engines for vehicles means less energy per vehicle operation. Turning thermostats down in winter (so less heating energy) and up in summer (less cooling energy). Insulating homes and businesses reduces the need for heating and cooling energy. So all these are valid ways to increase energy - use efficiency.

Answer:

1. turn off heat/ air systems and unplug electrical items while the office is closed
2. All of these are ways which we can lower energy waste
