Childlike imagination - diversified future energy sources

Human science and technology are developing rapidly, and the demand for energy is also increasing. According to scientists, if we continue to mine at this rate, the energy we most rely on - oil - will be completely exhausted by the end of this century. Non-renewable energy sources such as oil, natural gas and coal need to be used a little, but a little less, and we are looking for new energy sources. , has become an urgent task for us humans.

Let us boldly imagine what kind of incredible energy will be used by humans in the future world?

Let us build a magical country in our minds. There are waterwheels on the river - water energy; there are countless huge windmills standing on the fields - wind energy; the roofs of all the buildings in the city are sun Panels - solar energy; the floors of all roads, sidewalks, and corridors are paved with a strange material that collects the electrical and thermal energy generated by the movement of cars, people, and animals - frictional energy.

There is a factory that uses plants to produce plant fuel; there is a vehicle that can go to the sky and the sea, travel the universe, and is omnipotent. Its fuel is actually solar energy and biofuels. There is a kind of lamp that can shine forever as long as the river never stops.

Fantasy about the life of your future children. The sun shines on the little girl's black hair. Facing the morning light, the little girl opens her eyes. Her pink little hand reaches out from the soft goose down quilt and presses the third red button on the bedside. In the kitchen downstairs , the conveyor belt takes out the ingredients from the refrigerator, heats them with an electric stove, and delivers them to the dining table. All this is done by relying on heat and electricity collected from the ground.

After enjoying the delicious food, I put on my schoolbag and got into the smart ×× car. I clicked on the location of the school on the screen. The ×× car used the solar energy collected in the morning combined with an equal amount of plant fuel. We arrived in front of the school in an instant...

The future, this word full of hope, makes us look forward to it infinitely. Will mankind be more glorious in the future? Human beings are constantly advancing. What kind of energy will humans rely on in the future? Let us imagine the future and discover more environmentally friendly energy to benefit the world.
