Excellent Imagination Composition of Senior Two: Our Future New Energy
Just when I was at my wit's end, a strange robot appeared in front of me and said, "Hello, dear tourists, welcome to the world in 2046. I am your tour guide-Wo Wo. "
"2046?"
"Yes, it's time for the old man to send you." Wo Wo said, "Let me introduce you! In the past, there were oil, coal, electricity, bioenergy, tidal energy, wind energy, solar energy, geothermal energy and nuclear energy ... Because oil and coal are non-renewable energy sources and people don't know how to save them, they have been exhausted. Now, scientists have used hydrogen instead of oil as fuel, so now all cars on the street are driven by hydrogen. "
"Hydrogen-powered cars?" I don't understand, "although hydrogen has replaced oil, how can hydrogen make cars move forward?"
"Yes, hydrogen is a new clean energy with high efficiency and environmental protection. It exists in a large number of water molecules and can be separated by electrolysis for a large number of people to use. Now humans have developed engines that use hydrogen as fuel. The water vapor generated after hydrogen combustion will not pollute the environment, so people can drive without petroleum fuel. "
"oh! I see. "
"Fang Duo! ! ! Don't sleep, hurry to write a composition! " Mom's voice rang in my ear.
"ah? I fell asleep! It turns out that this is a dream, a beautiful dream! "
