Introduction Electricity is needed for improving human life quality and developing economy, however, it also brings us environmental problems such as air, water or soil pollution. It even makes life quality worse in less developed countries. All issues come from using efficient but not renewing resources as gas, coal and rock-oil. They vanish quickly too. So the problem must be controlled somehow. It is being done by EU too by accepting overall agreements and ratifying protocols of collective power saving and pollution breaking. But from the very beginning there are many significant things for all us to do. Everyone can do a simple action to make Earth a good place to live, so why don’t we try?

Tips on how to save even more electricity Turn off your television, video, computers, and other entertainment devices when they are not being used. Do not leave your television etc in standby mode. Devices can use up to 90% as much power in standby mode as when they are on, so it is a serious waste of energy when a device is left constantly on standby. Replace all of your inefficient incandescent light bulbs with energy efficient CFL bulbs. Replace halogen spotlights with much more efficient and longer lasting LED Spotlights Hang your clothes out to dry rather than using an electric drier.

Tips (continued) Cook many items at the same time when your electric oven is hot. Use a microwave to reheat food or to cook small portions. Although a microwave uses a lot of power, it does so over a very short time and so saves energy overall. Turn down your heating system. For every degree you lower your heat between 60° and 70° F you can save up to 5% on your heating bill. Wear an extra layer of clothing in the house so that you stay warm. Turn down individual radiators - for example, 16°-18° is warm enough for bedrooms whereas 20°-22°C is more comfortable in bathrooms. Rooms that are rarely used can have their heating turned all the way down or off.
