Understanding different ways to generate electricity can help you make better decisions about energy use—and even switch to greener options. In this guide, we’ll take a closer look at how we currently generate electricity, and how alternatives like solar and wind power could offer a brighter, ...
根据第一段的内容可知,我们使 用的大部分能源来自太阳,太阳帮助植物生长,进而产生了 化石燃料,再根据第三段中的“Green energy gives us almost 25% of the electricity we use today"可知,绿色能源为我们提 供差不多25%的电能,由此可推知,我们目前使用的电能大 部分来自化石燃料,故选A。 2.C 【解析】词...
energy sources and electricity, and ecosystems. Many children will enjoy the hands-on building experience. Project-based learning brings out the innate creativity of young minds and harnesses the energy of active learners, giving them the best chance to showcase their knowledge and understanding. Thr...
Using Tidal Energy to Generate Electricity Tidal Energy or Tidal Power as it is also known, is another water based power that exploits the vast energy source of the oceans tides to generate electricity. Tidal Energy is a “sustainable energy source”, as the Earth uses the gravitational forces...
T his uses the ocean tides to make electricity. But some kinds of tidal energycan kill many fish and other se a animals. Also dams(大坝)can create lots of clean energy. But dams create lakes and change the waythat rivers run. So they can do great harm tothe balance of nature aro...
