Advantages of Solar Power?
- Solar energy is a clean and renewable energy source.
- Once a solar panel is installed, solar energy can be produced free of charge.
- Solar energy will last forever whereas it is estimated that the world’s oil reserves will last for 30 to 40 years.
- Solar energy causes no pollution.
- Solar cells make absolutely no noise at all. On the other hand, the giant machines utilized for pumping oil are extremely noisy and therefore very impractical.
- Very little maintenance is needed to keep solar cells running. There are no moving parts in a solar cell which makes it impossible to really damage them.
- In the long term, there can be a high return on investment due to the amount of free energy a solar panel can produce, it is estimated that the average household will see 50% of their energy coming in from solar panels.
Disadvantages of Solar Power?
- Solar panels can be expensive to install resulting in a time-lag of many years for savings on energy bills to match initial investments.
- Electricity generation depends entirely on a countries exposure to sunlight; this could be limited by a countries climate.
- Solar power stations do not match the power output of similar sized conventional power stations; they can also be very expensive to build.
- Solar power is used to charge batteries so that solar powered devices can be used at night. The batteries can often be large and heavy, taking up space and needing to be replaced from time to time.
Five years ago, I attended a very big festival in Ha Noi. It’s called 1000th Anniversary of Thang Long – Ha Noi Festival. There are a lot of activities in this festival such as fireworks display, military parade, music performances, ect. It was organized very splendidly because the organizers are the Viet Nam government. Millions of people came to Ha Noi to participate in this great festival. It was held for ten days from October 1st 2015 to October 10th 2015. I saw lots of fireworks, parties, parades during these days. It was interesting. I took so many pictures on this festival because there were plenty of beautiful scenes. We organized this great festival to celebrate the 1000th anniversary of Thang Long – Ha Noi.
I love listening to music. Because listening to music will make me have a relaxed mind and relieve stress and fatigue after working and studying. Listening to music also helps me understand the author's emotional levels, know how to compose that song the author has to go through. I like to listen to sad, melodious and emotional songs the most. Usually I listen to Vietnamese songs but sometimes I listen to Chinese and Japanese songs ... And the songs I like best are: The devil comes from the paradise of China. Vietnam, Japan's hazy moon... because those are very good songs.

1 Make "simple syrup": Place the sugar and water in a small saucepan and bring to a simmer. Stir so that the sugar dissolves completely and remove from heat.
2 Juice the lemons: While the water is heating for the simple syrup, juice your lemons. Depending on the size of the lemons, 4 to 6 of them should be enough for one cup of juice.
3 Combine lemon juice, simple syrup, water: Pour the juice and the simple syrup sugar water into a serving pitcher. Add 2 to 3 cups of cold water and taste. Add more water if you would it to be more diluted (though note that when you add ice, it will melt and naturally dilute the lemonade).
If the lemonade is a little sweet for your taste, add a little more straight lemon juice to it.
4 Chill: Refrigerate 30 to 40 minutes.
Serve with ice, sliced lemons.
