    How much electricity can you save by reducing your screen brightness to 75%? - ProProfs

    How much electricity can you save by reducing your screen brightness to 75%?

    • 20%

    • 10%

    • 5%

    • 3%

    Correct Answer
    A. 20%
    Explanation
    By reducing the screen brightness to 75%, you can save 20% of electricity. Lowering the brightness level on electronic devices reduces the amount of power needed to illuminate the screen. As a result, less electricity is consumed, leading to energy savings. In this case, reducing the brightness to 75% allows for a significant reduction in electricity usage, resulting in a 20% decrease.

    How much of the cold air can be lost when you open the fridge door? - ProProfs

    How much of the cold air can be lost when you open the fridge door?

    • Up to 5%

    • Up to 60%

    • Up to 10%

    • Up to 30%

    Correct Answer
    A. Up to 30%
    Explanation
    When you open the fridge door, some of the cold air inside escapes and is replaced by warmer air from the surrounding environment. This exchange of air causes the temperature inside the fridge to rise. The correct answer suggests that up to 30% of the cold air can be lost when the fridge door is opened. This means that a significant amount of the cold air can escape, potentially impacting the overall temperature and efficiency of the fridge.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    True: If you have a gas, oil or LPG (liquefied petroleum gas) central heating system, it will always be cheaper to time the system so the hot water comes on only when required.

    Leaving the heating on all day on a low temperature is cheaper than turning the heating up and down or on and off as needed. - ProProfs

    Leaving the heating on all day on a low temperature is cheaper than turning the heating up and down or on and off as needed.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    False: For the majority of householders leaving your room thermostat on all day at a lower temperature will not only mean that your home will never be at a comfortable temperature but it will also waste heat when you do not need it. Room thermostats turn the heat on and off when your home reaches the set temperature that you feel comfortable at. Combine this with a timer control that tells your heating system to come on only when you need it to save money on your energy bills.

    How much energy can you save by only boiling the water you need in the kettle? - ProProfs

    How much energy can you save by only boiling the water you need in the kettle?

    • 16%

    • 66%

    • 36%

    • 86%

    Correct Answer
    A. 66%
    Explanation
    By only boiling the water that is needed in the kettle, you can save 66% of energy. This is because when you boil a full kettle of water, a significant amount of energy is wasted in heating the excess water that is not required. By boiling only the necessary amount, you reduce the energy consumption and consequently save 66% of energy.

    How much money does the UK waste each year leaving lights on unnecessarily? - ProProfs

    How much money does the UK waste each year leaving lights on unnecessarily?

    • £50million

    • £170million

    • £280million

    • £430million

    Correct Answer
    A. £170million
    Explanation
    The correct answer is £170 million. This figure represents the amount of money that the UK wastes each year by leaving lights on unnecessarily. This indicates a significant problem of energy wastage and highlights the need for more efficient and responsible energy usage in the country.

    How much less electricity do LED bulbs use than standard bulbs? - ProProfs

    How much less electricity do LED bulbs use than standard bulbs?

    • 60%

    • 70%

    • 80%

    • 90%

    Correct Answer
    A. 90%
    Explanation
    LED bulbs use 90% less electricity than standard bulbs. This is because LED bulbs are more energy-efficient and convert a higher percentage of the energy they consume into light, while standard bulbs waste a significant amount of energy as heat. LED bulbs also have a longer lifespan, further contributing to their energy-saving benefits.

    How much money can you save each year by switching off appliances rather than leaving them on standby? - ProProfs

    How much money can you save each year by switching off appliances rather than leaving them on standby?

    • £18

    • £26

    • £58

    • £86

    Correct Answer
    A. £86
    Explanation
    By switching off appliances instead of leaving them on standby, you can save £86 each year. This is because appliances on standby mode still consume a small amount of energy, which adds up over time. By completely switching them off, you eliminate this energy waste and save money on your electricity bill.

    What percentage of your annual home energy bill can be attributed to the efficiency of your boiler? - ProProfs

    What percentage of your annual home energy bill can be attributed to the efficiency of your boiler?

    • 30%

    • 40%

    • 50%

    • 60%

    Correct Answer
    A. 50%
    Explanation
    The efficiency of a boiler plays a significant role in determining the energy consumption and cost of heating a home. A boiler with higher efficiency will use less fuel to generate the same amount of heat, resulting in lower energy bills. Therefore, the percentage of the annual home energy bill that can be attributed to the efficiency of the boiler is 50%.
