Energy saving – message of Earth Day

      Various activities took place worldwide to mark Earth Day (April 22) and many new records were set on the occasion.
In Norway, a man invented a super-low cost solar energy panel that can be made for US$5. Creating low-cost products is an important way to limit the wasteful use of natural resources.
The importance of energy-saving was brought home in Ho Chi Minh City where the price of clean water reached record levels over the past two days as local people had to buy clean water at a price of VND200,000/cubic metre (US$11/cubic metre), which is considered the highest price in the world. The lack of water for daily use in HCM City was attributed to electricity cuts in some water plants. Furthermore, many water pipes were broken due to under-ground construction projects.
Vietnamese people are already familiar with Earth Day as its message has been disseminated widely. However, while energy saving solutions have been honoured in the most well-off communities in the world. The poorer people of Vietnam seem to delight in setting extravagant records entailing the waste of food, such as the largest noodle bowl, the largest pizza and the largest roasted cinnamon pork. These activities used hundreds of tonnes of food at a time when the World Food Organisation (FAO) has estimated that one billion people in the world are still facing hunger.
Energy saving is the most significant message of Earth Day. Let’s save the Earth.
