Can renewable energy sources replace fossil fuels?

Hello everyone! How are you today? It's Teacher Asuka.

There has been a lot of discussion and debate about renewable and sustainable energy sources such as solar energy. I agree that renewable energy sources can replace fossil fuels.

There are three reasons for this.

Firstly, the use of fossil fuels such as oil or coal causes global warming because they emit greenhouse gases such as carbon dioxide (CO2). In addition, the average of temperature of the earth is rising because of global warming.

Secondly, people have developed various renewable energy sources such as solar energy, hydrogen, wind power and so on. For example, Japan has recently decided to import liquified hydrogen, whose temperature is -253℃, and being shrieked to 1/800 of its original volume from Australia by ship. Transportation of hydrogen in liquefied form is one of the highest efficient methods, whose technology is from the state -of- the- art technology by Kawasaki, one of the Japan's major companies. Therefore, they are going to use it to make a lot more generators with no greenhouse gas emissions. I think it could be a smart idea for people to make the environment more environmentally friendly.

Thirdly, these renewable energy sources such as wind power, and hydro power are useful for the environment, because such renewable energy sources should not emit carbon dioxide. In addition, people can also reduce greenhouse gases as well. That is good for the environment.

As I mentioned before, I think that using such renewable energy sources instead of fossil fuels is for people to keep their healthy life and also to bring them a sustainable environment for the future.

Thank you for joining me as always.
See you next time!
