How does coal-electricity price linkage impact on the profit of enterprises in China? Evidence from a Stackelberg game modelCoal-electricity price linkageStackelberg game modelProfit impactsCoal priceTo mitigate the serious conflicts between market-driven coal prices and state-administered electricity ...
In traditional power plants, fossil fuels like coal, oil, or natural gas are burned to create heat. This heat is used to produce steam, which spins a turbine connected to a generator, creating electricity. In renewable energy systems, natural forces like sunlight, wind, and water are harnesse...
So how does all of this come together in your home? Let's find out. Circuit Breaker: At Work in Your Home This diagram shows the basic parts and design of a circuit breaker. HowStuffWorks The power distribution grid delivers electricity from a power plant to your house. Inside your hou...
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, ...
But how does the efficiency of thin-film solar cells compare to traditional cells? The theoretical maximum for silicon-wafer cells is about 50 percent efficiency, meaning that half of the energy striking the cell gets converted into electricity. In reality, silicon-wafer cells achieve, on average...
Electricity moves more easily through substances with lots of free electrons, like copper, than it does through substances with fewer free electrons, like carbon. In other words, substances like carbon have greater resistance. Moving current through substances with high resistance can create heat and...
How is electricity generated? Electricity can be generated from a variety of sources, including coal, natural gas, nuclear power, hydroelectric power, and renewable sources such as solar and wind power. How does electricity flow? Electricity flows through a circuit, which is a closed loop of con...
These power stations create mass amounts of energy to turn the turbines. Most of the time the energy is made from the heat, for example when coal is burned. More environmentally friendly power stations use wind or flowing water to turn these turbines. This is known as renewable energy ...
Most electricity is generated by burning coal and other fossil fuels. Every time you turn on the lights, you create a little pollution. (See the sidebar.) In fact, the average home pollutes more than the average car! (See my Carbon Footprint Calculator for the numbers.) So saving ...
