For instance, you could kiss your kids on their heads rather than their cheeks for a few days. You could ask your spouse to do bedtime stories and baths for a few nights. But obviously, you canât be so careful in your efforts to prevent germs from spreading that you feel like youâre shunning your kids.
If you grow short plants, you should definitely try LEDs. 1  The first series of costs on the chart represents an electricity cost of $0.12/kwH, or 12 cents per kilowatt hour (a kilowatt hour is 1,000 watts being used for one hour). 2  $0.12/kwH was the US national average cost for electricity in 2011.
One MWh is $150 since a KWh costs 15 cents on average in the US. If your electric bill is more or less than $150 per month, you are probably using more or less than one MWh of power. So if a 100 watt light bulb burns for 10 hours, it consumes 100 watts x 10 hours, or 1000 watt hours of energy (1 KWh).
