All calculations on this site are based on **current fuel prices**, they are checked regularly and calculations are automatically updated.

The costs calculated based on these fuel prices should be regarded as 'good estimates', given that fuel prices vary in different parts of the county and at different time of the year.

The calculations also have different levels of accuracy depending on the nature of the calculation. For example calculating the energy use of a known power output TV is very easy compared to calculating the effect on energy savings when insulating a cavity wall.

Throughout this site almost all calculations use the kilo Watt hour (kWh) as a unit of measure for energy.

The kWh was chosen as it is easy to relate to and is the standard measure for a unit of electrical energy on your electricity bill, i.e. 1 Unit = 1kWh. One kilo Watt (kW) is by the way 1000 Watts, and for completeness a Watt is a measure of power, which might be best described at the rate at which energy is transferred.

One kilo Watt (kW) is by the way 1000 Watts, and for completeness a Watt is a measure of power, which might be best described at the rate at which energy is transferred.

such that:- total energy = power × time.

For example a 40W light bulb kept on all day uses 40W x 24h = 960Wh (Watt hours), or approximately 1kWh. or a 1000W electrical heater kept on full power for 1 hour uses 1000W x 1h = 1000Wh (Watt hours), or again 1kWh.

To be clear the kWh is used for all forms of energy not just electrical, including gas, petrochemical, and coal etc. You will often find the energy relesased on combustion of these substances quoted in joules or calories, all we have done is convert these numbers to kWh. Incidentally we have found that many of the quoted energy values on the internet for these materials are wrong, particularly on internet sites selling them, so please beware.
