When we talk about how to make electricity, fossil fuel power generation is the most traditional and widespread method. In this process, power plants burn fossil fuels—likecoal, natural gas, or oil—to generate energy. In South Africa,coalhas been the primary fuel source for electricity,accoun...
One power station might be able to make electricity very cheaply (perhaps because it's very new and using natural gas) while another one (using old technology based on coal) could be much more expensive, so it might make sense to use the cheaper station whenever possible. Unfortunately, ...

These power-hungry monsters can do some serious damage. About 70 percent of our energy comes from non-renewable sources like oil and natural gas. When they're gone, they're gone for good. Also, some energy sources, such as the coal-burning power plants that generate nearly half of U.S...
If you had one neighborhood of indoor, pampered pugs and one neighborhood of unfenced basset hounds running wild, which group do you think could spread an outbreak of fleas the fastest? So, electricity needs a conductor in order to move. There also has to be something to make the ...
we can also use electricity to run our cars.(69)ESome countries have coal(煤)and they make electricity with that,but we might not always have coal either.Other countries have big,strong rivers,and they can use the power of water to turn turbines (涡轮机) and make electricity easily and...
Do we have enough energy sources to meet our future energy needs? These are two important questions that many people are asking today. Some people think that men might be able to solve both problems at the same time. They suggest using garbage as an energy source. For a long time, ...
We will use it to make sure that our power supply is producing the right voltage. The logic probe is optional. It makes it easy to test the state (1 or 0) of a wire, but you can do the same thing with an LED. Of the parts described above, all are easy except the 5-volt ...
Coal-electricity price linkageStackelberg game modelProfit impactsCoal priceTo mitigate the serious conflicts between market-driven coal prices and state-administered electricity prices in China, two kinds of mechanism of coal-electricity price linkage (CEPL) policies were proposed by the Chinese ...
