Cambodia is a country in Southeastern Asia, bordering the Gulf of Thailand, between Thailand, Vietnam, and Laos. Cambodia is located surrounded by mountainous and highland areas in the periphery and flat like a stove in the central area. Cambodia is the country that full of the natural resources. The natural resources are classified in two categories are renewable resources and non-renewable resources, and natural resources can be converted to power energy, but renewable energy is better than non-renewable energy because it is sustainable for our life, so renewable energy is the best energy in which people all over the world should consume it, because it has a little impact to our environment.
Renewable energy sources are being use all over the world. All countries over the world need energy to maintain their life. As in our book said “Energy is essential to maintain life.” But the percentage of using the renewable energy all over the world is not more than 10% of the world’s total energy. As you can see in the picture, renewable energy that we use nowadays are solar, geothermal, biomass, wind, and hydroelectric. Moreover, countries that have been using a lot of renewable energy mostly are developed countries, in contrast, for developing countries have been constructing renewable energy to maintain the economic in their countries. For example, Cambodia is trying to build more and more renewable energy plant power to gain more electricity to provide for its country, so it doesn’t need to buy electricity from other countries, and it can use this money for other section of country. In here we will pick some renewable energy sources to describe about them, and they are hydro power, wind power, and solar power. II. Hydropower
“Flowing water creates energy that can be captured and turned into electricity. This is called hydroelectric power, or hydropower.” KamChay hydropower plant

50% of the renewable energy that we consume in the world is from hydropower. As we know Cambodia has many of waterways, especially the Mekong River that we can be used for hydropower. Currently, there is a hydropower that just operated to produce electricity in Cambodia, and it is “Kamchay Hydroelectric Power Plant is located at Bokor National Park (BNP), Kampot, Cambodia. This infrastructure is of TYPE Hydro Power Plant with a design capacity of 193 MWe. It has 8 unit(s). The first unit was commissioned in 2011 and the last in 2011. It is operated by Sinohydro Corporation.” Cambodia still has other four investments with China that build more hydropower in entire Cambodia. The other four dams being constructed are Kirirom III hydropower dam with the capacity of 18 megawatts, Tatay river hydropower dam with the capacity of 246 megawatts, Atay hydropower dam of 120 megawatts and Russei Chrum Krom with the capacity of 338 megawatts. Five dams are invested by China in the total investments of 1.6 billion U.S. dollars, according to the reports of Cambodia’s Ministry of Industry, Mine and Energy. Moreover, Cambodia not even invests with China; it also has invested with Vietnam. “In April 2011, Cambodia announced that it would proceed with its Vietnamese partner on a US $700 million hydroelectric plant along the Lower Sesan River, with construction to start by the end of this year.” In contrast, hydropower is contrasted all around in Cambodia, but it is still have some impact to our country. Everything has it plus side and minus side. Hydropower is not except one. Here are the advantages of hydropower: * No pollution or waste produced.
* It is a very reliable energy source.
* Not expensive to maintain once the dam has been built.
* Can increase the plant’s production or decrease it whenever there is high or low demand. * Water can be stored, waiting to be used in peak time.
It also has many of disadvantages:
* Building the dam is expensive....
