In Western countries, electricity, gas and water are not luxuries but necessities. In developing countries, people even try to reduce using electricity, gas and water. Producers realize that products must not only work effectively but also save money. In a household, lighting often accounts for 10 percent to 15 percent of electricity bills. That is why some inventors from the Phillips and Company in Holland invented energy saving bulbs called compact bulbs. They are a good replacement for the 100-watt light bulbs which are often used. These new products use only a quarter of the electricity of standard bulbs and last eight times longer. Ultimately, the innovation like compact bulbs will save money as well as conserve the Earth’s resources.
