Why is Singapore classified as one of the most water-stressed countries in the world despite receiving plenty of tropical rainfall?

1.The rain that falls on our island is chemically too salty to collect into reservoirs.        

2.Our small land area lacks enough space to store massive amounts of rainwater.          

                   

3.Singaporeans use a hundred times more water per person than any other global city.  

4.Our local reservoirs evaporate completely within 24 hours of any major storm.            

2. Our small land area lacks enough space to store massive amounts of rainwater.

2.Desalinated Water                       

3.Melted snow from High Mountains

You turn off your television with the remote control, but a tiny red indicator light stays on. Is the TV still using electricity? 

1. No, turning it off with the remote stops electricity flow completely.

2. Only if the screen turns blue or shows a logo.                                      

3. Yes, it is using stand by power to stay ready to turn back on                    

4. Yes, but only during night time hours.                                                         

3. Yes, it is using stand by power to stay ready to turn back on.

2.Halogen spotlight bulb                         

3.Wax candle flame                                

4.LED (Light Emitting Diode) light bulb

Solar and wind power are fantastic green technologies, but engineers call them "intermittent." What is the main engineering challenge this creates for our power grid?

1.They produce too much electricity at night, which freezes transmission power lines during cold winter months.

2.They only work when the wind blows or the sun shines, meaning power grids cannot handle the sudden change from alternating current to direct current.

3.Power generation fluctuates depending on the weather, so we need large-scale energy storage or backup systems to balance supply with consumer demand.

4.The high voltage produced by wind turbines and solar panels permanently destroys standard household electrical appliances

What is a recommended energy-efficient temperature setting to set your air-conditioner to while keeping the room comfortably cool?

1. 16°C, so the room becomes a freezing winter wonderland. 

2. Around 23°C to 25°C, paired with a ceiling or standing fan.

3. 30°C, because it is hotter than the outdoors.                       

4. 10°C, to match the temperature inside an ice-cream freezer.

2. Around 23 to 25 degrees paired with a ceiling fan or  standing fan

When shopping for a new home appliance like a refrigerator or fan, what do more green ticks on the energy efficiency label mean?

1.The appliance is more energy-efficient and uses less electricity. 

2.The appliance makes twice as much humming noise.                

3.The appliance uses much more electricity to run faster.             

4. It shows how many times the box has been opened at the store.

1. The appliance is more energy efficient and uses less electricity.

Why is it a bad habit to stand in front of an open refrigerator door with it wide open while deciding what snack to pick?

1.The food inside will turn into ice cubes immediately.                                                        

2.The refrigerator interior light bulb will burn out instantly.                                                  

3.The entire kitchen will become too freezing cold to stand.                                                 

4.Cold air escapes, making the fridge work harder and use more electricity to cool back down.
