The energy in any process must come from somewhere. Sources of energy include the sun (called solar energy), wind, or water, but also include oil or coal, which are the fossil fuels we still burn on a large scale. Most often, energy from these sources is converted into electricity first...
Natural GasCoalShale GasPollutionBetween 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 ...
With gas however it is not so simple. That is because gas meters measure the volume of gas delivered to your meter (and not the energy content directly). This volume then needs to be converted into the equivalent kilowatt hours in order that akWh price per unitcan be applied to the ener...

Regenerative braking.For many EVs, the energy used to brake is converted into electricity to power the EV’s electric motor. Many drivers appreciate that this system extends the range of the EV – that’s how far it can drive on one charge. But this braking system also reduces the wear-...
The sun has a limited supply of hydrogen which it steadily depletes through the process of nuclear fusion. At this point,NASAestimates that the sun is a little more than 70% hydrogen. The vast majority of what remains is helium, which hydrogen is converted into during nuclear fusion. Eventua...
Hydropower is energy collected from flowing water that's converted into electricity or used to power machinery. Hydropower has been around for centuries, used to turn millwheels or drive early industrial machinery, but in modern use it typically refers to electrical generation. Today hydropower genera...
