There is plenty that you can do to help the process of energy conservation . You can save energy by doing things like making sure that the kettle doesn't contain more water than that you need , always washing a full load in the washing  machine rather than a half load , or turning up your air - conditioner by 2oC - this could cut your electricity bill by 10% . Make sure that hot water taps are not left running and replace washers if your taps drip . at work , you can turn off any light and your computer if you are not using them . Change to energy - saving light bulds - these use much less electricity , and often laswt eight times longer than an ordinary buld . Draw back your curtains and  turn off the light during the day . Switching off electrical app;iances  when they are not in use makes a big contribution to enery-saving , too.
