In order for electricity to flow, a current has to be created and maintained. This is done using a generator device. Generators are what keep the electrons stimulated and moving. This process of generating energy, in effect, creates more and more of the same. Once a current of energy, or...
Carbon dioxide (a molecule made up from one carbon and two oxygen atoms—CO2 in chemists’ notation) is a greenhouse gas, which means it contributes to the so-called greenhouse effect. Carbon dioxide and other greenhouse gases in the air trap some of the heat Earth would lose into space, ...
Many different methods can be used to make the shafts of the generators rotate and produce electricity. In wind turbines, the propeller rotates the shaft. In coal and nuclear power plants, the heat from burning the coal or from the nuclear reaction creates steam to run a turbine that drives ...
Rising natural gas prices affect us all—and electricity bills too. Here’s why it’s happening and what to do about it in plain language. Natural gas price forecast for 2022-23 included.
Between 2008 and 2012, the delivered price of natural gas to the U.S. power sector fell 60 percent. This paper addresses, in theory and in practice, the effects of this negative price shock on electricity consumers and the environment. We demonstrate with a simple model that the larger the...

'Green gas' is no panacea: Electricity is cheaper The gas industry has another solution in mind: instead of switching from gas to electricity, it suggests using "green gas"—biomethane or "green" hydrogen. Biomethane is chemically identical to natural gas, but is derived from biological material...
Natural Gas:This commodity is used to heat homes, help generate electricity, and also has other uses in the commercial and industrial industries. Natural gas contracts are sold by 10,000 million British thermal units (mmBtu). All contracts are traded in U.S. dollars per mmBtu. The final ...
