【题目】ENERGY Energy = the ability to do work! Anything that moves needs some kind o f energy to make it work. S ome sources o f energy will eventually run out. Others will never be used up.Let's start by looking at a nonrenewable(不可再生的)source o f energy--fossil fuels....
To produce this kind of energy, people "collect" sunlight and change it into electricity. It takes special equipment to do this, but once the equipment is made, solar energy is free. Collecting solar energy does not produce pollution, so it's a "green" way to create electricity for every...
Energy-saving and emission reduction 气候变化是人类面临的全球性问题,二氧化碳排放温室气体猛增对生命系统形成威胁。世界各国以全球协约方式减排温室气体,中国提出“2030碳达峰”、“2060碳中和”目标,即“二氧化碳人为移除抵消人为排放”,承诺二...
Food energy can be defined as the chemical energy derived from food people and animals consume. In this sense, human beings and animals must eat food to acquire the energy necessary for the body's healthy functioning. Without food, the body uses up the stored glucose as energy and later ...
Osaka is a city that blends rich history with modern energy, making it one of Japan’s most exciting destinations. Known for its warm and friendly atmosphere, the city is often considered more laid-back compared to Tokyo, with a vibrant culture that embraces fun, food, and entertainment. Whe...
The sun is the main source of energy for almost every living thing on Earth. It gives a plant the light energy it needs to photosynthesize, which converts that energy into a storable form (glucose) and keeps plants alive. Photosynthesis also produces the
To save our planet we should use a new class of renewable energy sources, like wind turbines, solar panels, biofuels and hydrogen. Because our need for power is constantly increasing in the future we will have to produce more energy, which is associated, among other things, with greater ...
