- What you should do to save energy
With fast growth of civilization there is also an ever mounting need for energy. Energy may be in the form of fuels or electricity. Petrol is a liquid fuel which is used widely nowadays. But this kind of fuels is likely to be exhausted at the rate man is using it recently.
To meet the challenge, various methods have been suggested. One is to minimize the man’s demand in using the energy. Non-essential consumption should be minimized. During certain days of the year, people all over the world turn off the electricity for 1 hour to save the energy. Modern gadgets consuming energy should only be used when they are absolutely necessary.
Energy conservation is possible through modernization of plant and equipment. People should replace the obsolete equipment by the modern ones.
Energy can be saved on transport by the following methods. People should commute by the rail rather than by cars and vans. The transport must be improved with a view to sparing the energy. Cities must be planned in such a way that the commuting distance from this place to others is minimized.
In industry, many things could be done to reduce waste of energy or to economize energy. The machine maintenance needs to be tightened; heater must be utilized properly. When systems are streamlined, economy in fuel is obvious. Instead of using materials requiring higher energy, those which require lower energy should be used.
We hope man with his ever rising urge for existence will cope up with this urgent problem and find alternatives.

- There are two types of energy sources, Renewable and Non-Renewable sources. Renewable energy sources are sources that can be replenished or which are available naturally in excess. Non-Renewable energy sources are limited in their availability.

Once being a basic food of farmers and poor families in Vietnam, com tam or broken rice is now a favourite dish of most Vietnamese. It is said that the best broken rice can be found in Saigon. When you come to Saigon, you should try this dish at least one time and you will not regret it.
Com tam literally means broken rice. Broken rice originally consisted of grains which were broken during the harvesting and cleaning of rice. In the past, as most people preferred to eat the long, whole grain rice, broken rice grains were difficult to sell and usually eaten by the Vietnamese working class because of the cheap price. Nowadays, often favored over long grain rice for its unique flavour and texture, broken rice is one of the best-loved fares in Vietnam.
Local broken rice eateries can practically be found on every street in Saigon. A broken rice dish is served with many beautiful colours from grilled pork chop with multi-flavour to steamed egg, shredded pork skin, pickles, vegetables such as tomatoes, cucumbers ... and especially sweet fish sauce that is the spirit of the dish.

Egg coffee, called Cà Phê Trứng in Vietnamese, was first invented by Nguyen Giang in 1946. There was a shortage of milk in Hanoi due to the French War. Mr. Nguyen reatively began adding whisked eggs to his coffee instead.
The original version was a bit, well, eggy. But over time the recipe was modified with the addition of sugar, condensed milk, and even Laughing Cow cheese. No one knows the recipe for sure since it’s a secret recipe. These days Egg Coffee is a staple of Hanoi coffee culture and a must-try while in Hanoi!
What does it taste like? Well it’s incredibly thick and rich and creamy. Closer to a dessert than a beverage. Liquid tiramisu is the most accurate description we’ve heard.
Nguyen Giang still has a café where you can try his famous recipe, or you can grab a cup of Egg Coffee at dozens of coffee shops all over Hanoi.
