What is the "true cost" of electricity Jean-Marc Jancovici

The lowest price tag per installed kW is for gas then for coal then hydro and nuclear. Wind is apparently not very costly but as the load factor is lower than what it is for gas or coal (the fraction of the time during which the turbine is producing electricity) the contribution per kWh is higher we will discuss that below.

Energy Cost Comparison

Different energy sources are measured in different units litres therms BTU kWh units cubic metres and many more. This makes it very difficult to compare the actual costs for powering a heating system between different energy sources. For this reason standardised units and costs are needed. We have done these calculations for the main fuel

Why Alberta Electricity Bills are Getting Higher — and

In January 2012 electricity rates in Alberta reached an all-time high (15.06 cents/kWh). The energy transition The energy transition from fossil fuels to renewable sources is quickly taking shape in Alberta. By 2030 coal-fired electricity generation will be phased out in the province being replaced by renewables and natural gas.

Energy densityWikipedia

Energy density is the amount of energy stored in a given system or region of space per unit volume lloquially it may also be used for energy per unit mass though the accurate term for this is specific energy.Often only the useful or extractable energy is measured which is to say that inaccessible energy (such as rest mass energy) is ignored. In cosmological and other general relativistic
