There are many types of energy sources. In a world where the instability of both society and nature is increasing, the issue of energy is a hot issue of great concern. Fossil energy sources, which have been considered as the main source of energy, are gradually becoming scarce and are also the cause of many immobility and disputes between countries around the world. The following energy sources are available: Nuclear Energy, Compressed Natural Gas; Biomass energy; Geothermal energy. Meanwhile, as scientists predict, with the current rate of exploitation and use of fossil resources, within a few centuries our descendants will have to bear serious consequences. Since then, the need for alternative energy sources has become more and more urgent, and more and more alternative energy research projects have been started and developed. However, not 100% of them are suitable for future development.

Solar energy captured by solar panels is a limitless form of energy, as the earth is bombarded with extreme amounts of solar energy every day, according to the National Renewable Energy Laboratory. It's also clean, producing no carbon dioxide, and is very low-maintenance, since solar panels have no moving parts.

Unfortunately, the National Renewable Energy Laboratory says its high installation cost makes it up to four times more expensive than the cost of electricity from a standard utility company. For optimal operation and maximum energy production, it requires year-round sunny weather and is very expensive if repair is necessary, according to the U.S. Environmental Protection Agency.

Năng lượng mặt trời thu được bởi các tấm pin mặt trời là một dạng năng lượng vô hạn, vì trái đất bị bắn phá với lượng năng lượng mặt trời cực lớn mỗi ngày, theo Phòng thí nghiệm năng lượng tái tạo quốc gia. Nó cũng sạch sẽ, không tạo ra khí cacbonic và bảo dưỡng rất thấp, vì các tấm pin mặt trời không có bộ phận chuyển động. Thật không may, Phòng thí nghiệm năng lượng tái tạo quốc gia cho biết chi phí lắp đặt cao của nó làm cho nó đắt hơn gấp bốn lần so với chi phí điện từ một công ty tiện ích tiêu chuẩn. Để hoạt động tối ưu và sản xuất năng lượng tối đa, nó đòi hỏi thời tiết nắng quanh năm và rất tốn kém nếu sửa chữa là cần thiết, theo Cơ quan Bảo vệ Môi trường Hoa Kỳ

As you know, sources of energy like solar energy, wind energy,.. are very important. People use them for many things:cooking, heating,ect...But, almost the sources of energy have the disadvantages and advantages. There are two kinds of energy:non-renewable and renewable energy. Non-renewable is very popular in many countries. They are abundant, available and easy to use. However, they won't last forever and they're harmful for the environment. And, people will use renewable energy to solve the problems of non-renewable energy. Renewable sources of energy are forever and they're clean and safe, too. Nevertheless, they have some problems, too. For example, nuclear is clean but it's dangerous to use. Wind power has many advantages but it isn't available,... On the other hand, there are some sources of energy don't have some serious problems like solar energy. It's the reason why people use solar energy in the future. So, what should we do to save energy? We should use them properly and use them less. We should use less cars or motorbike, too. It also have the enviroment. Energy is very important, we should protect them for our life in the future.

There are a lot of disadvantages of living in a big city, air pollution is among the most serious problems. Firstly, air pollution comes from the factories in the city. Big cities attract a lot of both inside and outside investments, so the number of factories is increasing quickly. This makes the air extremely polluted by smoke from factories. Secondly, that there are too many transportation means also makes this problem worse. Exhaust from cars, motorbike is one of the factors that make the air polluted. To conclude, air pollution, which contributes to making more and more people get many serious diseases, such as lung cancer, tuberculosis and so on, is a big drawback of city life.

My house primarily relies on electricity and gas for energy. Electricity powers most appliances and lighting, offering convenience but contributing to high consumption. Gas fuels the heating system, providing warmth efficiently but releasing emissions. To save energy, I've adopted simple habits: switching to LED bulbs, unplugging devices not in use, and using energy-efficient appliances. I've also improved insulation and sealed drafts to minimize heat loss. Moreover, I'm conscious of water usage, opting for efficient fixtures and practicing conservation. These steps not only save energy but also reduce environmental impact, aligning with my commitment to sustainability.

Hello everyone, today I'd like to tell you some information about types and sources of energy. Energy is classified into two main groups: renewable and non-renewable.

The energy generated from natural sources such as the sun, wind, rain, and tides is called renewable energy. They are plentiful and can be generated again and again. They also have low carbon emissions so they are considered green and environment-friendly. Moreover, using renewable energy can reduce your electricity bills. Unfortunately, solar energy can be only used during the daytime but not during night or the rainy season. Geothermal energy also can bring toxic chemicals beneath the earth's surface to the top and can create environmental changes.

Non-renewable energy is the energy taken from other sources that are available on earth.They are limited and will run out in the future. They can't be re-generated in a short time.Fossil fuels - natural gas, oil and coal - are examples of them. They are cheap and easy to use. However, when burnt, they release toxic gases in the air so they cause serious environmental changes such as global warming. And the important thing is that non-renewable sources will expire someday.
