Rather than extracting properties for labels, titles, etc. and then performing text comparisons, just add an assessment test to require their use in the solution. A unit of electrical energy, particularly for utility bills, is the kilowatt-hour (kWh); one kilowatt-hour is equivalent to 3.6 megajoule. Electricity usage is often given in units of kilowatt-hours per year or other time period. This is actually a measurement of average power consumption, meaning the average rate at which energy is transferred. One kilowatt-hour per year is about 0.11 watts.
