Renewable energies (or renewables) are ways to generate energy from (theoreally) unlimited natural resources. These resources are either available with no time limit or replenish more quickly than the rate at which they are consumed.
Renewable energies are generally spoken of as opposed to fossil fuel energies. The fossil fuels’ stocks are limited and non-renewable in the human timescale. The most known examples of these resources are coal, oil or natural gas. On the contrary, renewable energies are produced from renewable sources. Here, we’re talking about energy coming from solar rays, wind or water cycles – all theoreally unlimited on a human scale time.
Renewable energies are also often referred to as “green energies” or “clean energies”. Still, this doesn’t mean that these energies aren’t harmful to the environment and have zero impact. Nonetheless, they have a low environmental impact compared to fossil fuels. That’s why they’re increasingly becoming important elements in companies’ CSR strategies in terms of sustainable development.
There are several types of renewable energies that are produced by different sources such as the sun, wind or water. In fact, these renewables’ power consumption has been growing over the last year. They have provided 8% of the world’s electricity in 2017 and they now cover 1/3 of the power mix in Europe. At the same time, the energy grid gets 1/4 of the total energy in China and 1/6 in the United States, India, and Japan. Let’s learn more about them below.

- Is Solar Energy Really Green And Sustainable?
1 – Solar Energy
This type of renewable energy comes directly from the capture of solar radiation. Here, the solar radiation is absorbed by specific sensors and rebroadcasted following 2 possible operation modes:
- Capturing sun rays and directly converting them into energy through photovoltaic solar panels;
- Capturing, collecting and turning the sunlight into heat that warms up water or air.
Examples of Solar Energy in the World
It’s estimated that in 2017 1,6% of the worldwide generated energy came from solar sources. At the same time, solar power also contributed to 20% of the total energy growth in this same year. Some of the most known sources of solar energy are:
- The Kurnool Ultra Solar Park in India. It has a total generation capacity of 1000MW and over 4 million solar panels installed;
- The Longyangxia Solar Park in China that has a total capacity of 850MW and covers around 25sq km.
- The Kamuthi Solar Facility in India: it has a total capacity of 648MV and covers 10sq km.
Is Solar Energy Renewable or Nonrenewable?
Solar energy is inexhaustible in the sense that it will cease once the solar system’s star – the sun – dies. However, many people wonder if, from a perspective of human’s being able to capture and use solar energy in the long-term, whether solar energy is renewable or nonrenewable.
[Full answer available soon.]
2 – Windpower, a Renewable Energy
Wind power is another renewable energy. Here, the wind’s kine energy makes turbines spin and creates a mechanical movement. Afterward, a generator transforms this mechanical energy into electricity. There are several types of wind renewable energies: onshore wind turbines, off-shore wind turbines and even floating wind turbines. But the operating principles are basically the same for all these types of wind-generated energy.
Examples of Wind Power in the World
Wind power continues has also been growing, In fact, it provided 4.4% of global power generation in 2017. The highest installed wind capacity belongs to China (164GW). At the same time, in the EU, wind power provides 15% or more of the energy generated in several countries such as Germany, Portugal or Lithuania. Some of the most known sources of wind power energy are:
- The Gansu Wind Farm in China. It is still under construction and it will be able to produce 20,000MV of power by 2020;
- The onshore Muppandal Wind Farm in India with a capacity of 1,500MW and over 3000 turbines;
- The Alta Wind Energy Center in the U.S. with a total capacity of 1,548MW that’s expected to reach 3,000MW by 2040;
- The Walney Extension in the UK. It has a total capacity of 659MW and it’s the world’s largest offshore farm.
3 – Hydro-Electric Power
Hydro-electric power consists in the transformation of the kine energy of the water (from rivers, dams, marine currents or tides) into mechanical energy by turbines.

Examples of hydro-electric power in the world
- The Sihwa Lake Tidal Power Station in South Korea. This is the world’s biggest tidal power installation and it has a capacity of 254 MW;
- The Rance Tidal Power Station in Brittany, France, has a 240 MW capacity;
- The Three Gorges Dam in China is the world’s largest power station in terms of installed capacity (22,500 MW).
4- Biomass
Biomass is made up of organic materials from plants or animals that contain stored energy. The combustion of these natural materials produces renewable energy. Some examples of generating energy from biomass are:
- Directly burning solid biomass garbage or wood to produce heat;
- Converting biomass into biogases such as methane or CO2 due to the bacterial activity that happens in the absence of oxygen (as is the case in landfills);
- Using sugar or corn crops to create biofuels such as bioethanol or biodiesel and mixing them with fossil fuels afterward. As a matter of fact, the world’s biofuels production increased by 3.5% in 2017.

Examples of Biomass Energy in the World
Some of the most known biomass power plants in the world are:
- The Iron Bridge power station in the UK, with a capacity of 740MW. It uses wood pellets as the main fuel;
- The Alholmenskaft power station in Finland. It has a 260MW energy generation capacity;
- The Polaniec power plant in Poland that uses mainly agricultural by-products and wood residues. It has a 205MW capacity.
5- Geothermal Power as a Renewable Energy
The Earth generates and stores geothermal energy. In other words, radioactive materials decaying inside the Earth are emitting energy. Electricity can be created using directly or indirectly this energy, depending on the technology implemented. There are 3 main ways to use geothermal energy:
- Generating electricity directly from the Earth’s heat;
- Producing heat directly from hot water boiling on the planet’s surface;
- Using pumps over the shallow ground to heat (and also to cool)

I have lived in Ha Noi for many years. Ha Noi is a big and busy city. There are lots of vehicles on the road all day. There are lots of cars, buses, taxis and trucks on high ways. Vietnamese people like moving by motorbike. Almost every family has a motorbike. The traffic jam is often at about 7 a.m and 5 p.m because it’s the time when people go to work or school and come back home. There are sometimes accidents on the road. Therefore, to reduce these problems, we need to obey traffic rules to reduce accidents as much as possible.
Bài dịch
Tôi đã và đang sống ở Hà Nội nhiều năm. Hà Nội là một thành phố lớn và bận rộn. Có nhiều phương tiện trên đường mỗi ngày. Có nhiều ô tô con, xe buýt và xe tải trên đường cao tốc. Người Việt Nam thích di chuyển bằng xe máy. Hấu hết mỗi gia đình đều có một chiếc xe máy. Ùn tắc giao thông thường vào lúc 7 giờ sáng và 5 giờ chiều bởi vì đây là thời điểm mọi người đi làm hoặc đi học và trở về. Có nhiều vụ tai nạn trên đường. Vì vậy để giảm thiểu các vấn đề này, chúng ta cần tuân thủ các luật giao thông để giảm thiểu tai nạn nhiều nhất có thể.

I come from (..say the city name…) and this city accommodates a large number of population. Due to this huge population and the increased number of public and private cars, the city often faces bad traffics.
The number of people living in this city, the cars they are using and the public transportation they need is higher than the number of roads. As a result, the traffic jam often occurs and people have to suffer. Another reason for the traffic jam is the unauthorised parking if cars in the street. People do not often follow the exact traffic rules and because of their sincerity, we often face the horrible traffics in the street.
The traffic jam in our city is one of the terrible things the city dwellers have to face. People get stuck on the roads and they have no idea when they would be able to reach their destination. Because of this jam, people often miss important schedules, students can’t reach school in time and the outcome is devastating. Because of the jam in the street people have to schedule accordingly and the total time killed in the street is simply a waste of time.
There are many steps which should be taken to reduce the jam in the street. First of all the people who are driving in the street should very strictly follow the traffic rules. The traffic control authority should more strictly apply the rules. The number of private automobiles is increasing rapidly. Many single families own multiple cars and thus increase the number of total cars driving in the street. The rule should be imposed on purchasing cars and the price of the fuel could be increased as well. The public transportation system should be improved so that people can travel on public cars. The city has more population than it can comprise and decentralisation of industries, offices and educational institutes can be another solution to this abhorrent problem.
The big city where I live and some other places have some traffic problems. One of the traffic problems is that there are too many traffic jams every day, so there are many traffic accidents too. Secondly, some people don’t obey the traffic laws. In addition, there are too many people using the road and too many vehicles, while the roads are narrow and bumpy. In short, there are some traffic problems in big cities. The street should be wider and everyone should obey the traffic rules strictly.
