Recently, some people believe that nuclear, solar, wind and hydropower provide cheap and clean energy. The advantages of these sources of power far outweigh their disadvantages. I totally agree with that first of all, energy should be a very hot topic today. When it comes to energy, there are many abundant energy sources in our life. What impresses me most is solar energy. Solar energy exists everywhere in our life, just like the water heater in my own home.Solar energy is a kind of renewable energy. It refers to the thermal radiation energy of the sun. Now there is solar energy in many places in life, such as solar lamps, solar power plants and so on. There are few non renewable resources on the earth, such as nuclear energy: coal, crude oil, natural gas, oilIt is estimated that oil and gas will dry up in 70 years; Coal dried up after 200 years.
In recent years, oil prices have risen sharply, and we are facing an energy crisis. Therefore, from now on, we should vigorously develop other new energy sources, such as solar energy, wind energy and bioenergy.In fact, we are now using these renewable energy sources.

In Arab countries such as Dubai, oil exploitation is not as frequent as before, because oil resources are particularly scarce. Although those areas are rich in oil resources, our human use of oil is particularly frequent, resulting in an increase in the original price of oil and a decrease in reserves.In short, as stated in task 1: 'renewable energy is very important for the future of our planetâ Indeed, the energy crisis is very terrible, and the frequent use of non renewable resources such as oil will pollute the life and environment on earth. The awareness of environmental protection is known by everyone in today's people's life! Reduce the use of gasoline vehicles and advocate electric vehicles, such as Tesla electric vehicles in the United States and various electric vehicles produced by other automobile manufacturers in the world. On the one hand, reduce the use of gasoline, and secondly reduce environmental pollution.
The extensive use of electric energy also reduces unnecessary safety accidents. As mentioned in the data, accidents often occur among workers in mines. Reduce the use of coal and oil. These unnecessary accidents and troubles can be avoided as far as possible.I live by the Yangtze River. It should be rich in water resources, but water pollution has been serious in recent years. The original a land flowing with milk and honey has experienced drought and flood in many places, and crops can not be produced normally. Although the earth is rich in water resources, with a total of about 1.351 billion cubic kilometers, 97.47% of it is marine water.
Fresh water resources are less than 3%. Of the less than 3% of fresh water resources, 1.76% are in the form of glaciers at the poles or on high mountains, which are difficult to use, and a large number of fresh water resources are deeply buried underground (quoted Google). Since last year, the horn of Africa has suffered the worst drought in 60 years, and about 10 million people have been affected.
The resulting food crisis has aroused widespread concern in the world. FAO calls on the international community to actively assist and help solve the local famine problem (quoting Google). In conclusion, we should call on the world to reduce the use of non renewable resourcesOf course, some people agree with this statement, and some certainly oppose it, but I still insist on my choice. As stated in task 3, 'the debate on whether to use fossil fuels or turn to environmentally friendly and renewable energy'. Some people think that these industries do provide a lot of employment opportunities, but I think nuclear energy, solar energy Wind and hydropower provide cheap and clean energy. The advantages of these energy sources far outweigh the disadvantages, so I still think my choice is wise.
