The UK produces most of its electricity from fossil fuels. Many people in the UK leave their televisions in ‘stand by' mode when not in use, instead of switching them off. It is better for the environment if people switch off their televisions, instead of leaving them in ‘stand by' mode. Explain why?

The correct answer to this open question is the following.

Although there are no options attached we can say the following.

It is better for the environment if people switch off their televisions, instead of leaving them in standby mode.

Indeed, it is better to do that for a simple reason. Television needs electricity to work. When English people left their televisions in standby mode, the TV is still using electricity. It is consuming energy. This, of course,  generates electricity. This electricity is produced by fossil fuels and when this happens it is polluting the environment. Why? Because it produces carbon dioxide or CO2. This also impacts the critical phenomenon of climate change and global warming.

If the UK produces most of its electricity from fossil fuels, this means that these nation is contributing to climate change and polluting the environment, the air, the water. That is why people in the UK should leave their televisions in standby mode when not in use, instead of switching them off.
