Online calculator for calculating the amount of energy resources consumed
With this online calculator, you can calculate how much of a particular fuel you will use to heat your home. And how much money you will spend on it.
For example: You are currently heating your house with coal and you want to know how much you will spend on electricity when you switch to electric heating and how much it will cost you to heat your house with electricity. And don't forget the "Efficiency" column. Different heating boilers have different efficiencies. Coal and wood boilers have less efficiency than gas and electric boilers.
Data on the calorific value of these energy carriers is taken from this Wikipedia article.
