The sievert represents the equivalent biological effect of the deposit of a joule of radiation energy in a kilogram of human tissue.
The size and brightness of the resulting flame depends upon the flammable material's flow rate in terms of joules per hour (or btu per hour).
The power (watts) is equal to change in gravitational potential energy (joules) per unit time (seconds).
Indeed, there is no commonly accepted measure of energy, although of course tons of coal or oil equivalent are used, kilowatts are used, and sometimes joules.
Likewise, there is only one acceptable unit for power or heat transfer, the watt (or joule per second).
The new clause would significantly lower these thresholds to 5.42 joules.
In my view it could be applied—if we are talking about the joule—to all domestic tariffs and even include the rating of motor-cars.
The joule is accepted by scientists as being the correct unit for energy.
