When you turn off a device, it stops using power. When we turn off a device, such as television, it goes into stand-by mode. Devices in this mode still use power, and older devices in stand-by mode can use even more. This happens because electricity continues to leak from the device, even when it is turned “off”. To make sure your appliance is in fact off, remove the plug from its power supply. What’s really green? Most of us are aware that we must take care of the environment, and the majority of us take steps to save energy and reduce waste and pollution. But recently, some “green truths” have been shown to be only half true, or even completely false. Here are some common ones. Which are really green? Paper shopping bags are better than plastic ones. Plastic bags cause litter and are a danger to wild animals, which mistake them for food. It takes hundreds of years for plastic to break down, but much less time for paper. Because of this, people think paper bags are the better environmental choice. . Eating local food is good for the environment. It seems like common sense: eating local food should be better for the environment, because it does not need to be transported long distances and kept cold during transport. Unfortunately, it is notthat simple. It is the production of food, not its transport, that uses most of the energy and produces most of the greenhouse gases. In some cases, local produce might have used more energy and produced more greenhouse gases than produce grown a long way away – even taking into account its transport. It’s better to take a shower than a bath. It depends on how long you spend in the shower and how large your bath is. If you spend more than eight minutes in a shower, you’ll use as much water as in a bath – about 50 litres of water. Therefore, the key is to keep your shower time as short as possible. Environmental awareness is now part of daily life. But it’s worth checking common ideas and opinions to see what’s really green.
