选项B的意思是“通过水流产生能源” ,选项C的意思 是“给车辆加汽油” ,选项D的意思是“建立一个水 坝发电” ,根据文章第一行“Hydropower is power that is generated from moving water such as rivers.(水力发电是从河流等水流中产生的电 能。 )”所以本题选B。
【题目】Hydropower Energy Hydropower is power that is generated from moving water such as rivers.Hydropower is a renewable energy source. This means that using a dam or a river to generate electricity doesn't use up any limited resources like coal or gasoline.How Do We Get Power from Water?
A water wheel turbine for generating power from a water current in a body of water, comprising multiple water wheels. The wheels have paddles, which have wings that channel the water current to a successive row of paddles on an adjacent wheel. The wings of the waterwheels work as self-...
(current) to turn turbines placed directly in domestic rivers, estuaries, coastal waters or tidal flows, which in turn drive electrical generators that convert the kinetic energy of the moving water (hence its name “Hydrokinetic Energy”) into electrical energy. The generated electricity can then ...
Moving water has energy. Water power makes 16-80% of the electricity we use.Wind PowerIs wind power new? No, it isn't. People used wind power many years ago. Wind power makes 40% of the electricity we use.Solar PowerSun power comes from sunlight. The sun shines on solar panels(太阳...
This moving water can make electricity. We call it tide power. There is also heat un der the Earth's surface. Scientists can use this heat for energy,which is called heat power. We may find other sources of green energy in the future.Some day, green energy could make 100% of the ...
Hydroelectric power produces electricity using moving water. Electricity can be generated when coils of conducting wire rotate in a magnetic field... Learn more about this topic: Hydroelectric Energy | Definition, Advantages & Disadvantages from Chapter...
CO2 compressor pump common shaft driven from turbine with one moving part. This remarkable turbine is the next step in gas and liquid turbines for HVAC, data center waste heat to energy, closed-loop quiet power production, vehicle HVAC, commercial chiller conversions, and more ... Cavgenx ...
The backpack is IPX4 water-resistant and can carry a load of 66 pounds. The 512-watt-hour battery is enough to keep you going for a while, and it comes with 87% usable capacity, which is pretty good. You can even pair it with a 100-watt portable solar panel and solar generator ...
Micro-hydropower plantis the small-scale harnessing of energy from falling water such as steeped mountain rivers generating typically about 5 kW–100 kW using the run-off-river type flow of water; it does not require the construction of expensive dams. In principle, the working of theMHPP...
