Chancellor George Osborne today announced that employers will no longer have to pay national insurance contributions (NIC) on apprentices aged 24 and under.
The average household in Massachusetts uses about 630 kilowatts of electricity a month, according to the most recent US government data. With National Gridâs new winter rate of 24.24 cents per kilowatt-hour, a typical monthly bill would run slightly more than $150. A National Grid spokesman, Jake Navarro, said that two-thirds of the cost comes from the purchase of electricity from power plants, compared to just over half last winter.
A kilowatt-hour is the amount of energy equivalent to a steady power of 1 kilowatt running for 1 hour, or 3.6 megajoules. Energy cost can be illustrated in a similar example: a 100-watt (i.e. 0.1 kilowatt) light bulb turned on for 8 hours uses 800 Wâh or 0.8 kWâh.If the energy cost is 25 cents per kilowatt-hour, it would cost 0.1 kW Ã 8 h Ã $0.25/kWâh = $0.20.Whereas individual homes only pay for the kilowatt-hours consumed, commercial buildings and institutions also pay for peak power consumption (the greatest power recorded in a fairly short time, such as 15 minutes).he kilowatt-hour (symbolized kWâh) is a unit of energy equivalent to one kilowatt (1 kW) of power sustained for one hour. One watt is equal to 1 J/s. One kilowatt-hour is 3.6 megajoules, which is the amount of energy converted if work is done at an average rate of one thousand watts for one hour.
