| Like coal, crude oil is a fossil fuel (because it was made from once-living matter). Chemically speaking, crude oil is a blend of hydrocarbon compounds (compounds composed of hydrogen and carbon atoms). Thus, many people refer to fuel oil, gasoline, and kerosene as hydrocarbon fuels.Some of the hydrocarbon compounds in crude oil are light-weight gases. If the underground pressure above a pool of oil is not too great, these gases may leave the crude oil and collect in a pocket above it. This is where natural gas comes from. Natural gas is a blend of light-weight hydrocarbon gases. | |
HOW TO READ YOUR ELECTRIC METERYour electric meter has an important job todo... it measures how much electrical energy is consumed by the many electric lights and electrical appliances in your home. You should learn how to “read” your meter so that you can keep track of how much electrical energy you and your family use each day. Then, you will be able to monitor the effectiveness of your energy-conservation efforts.On most electric meters (probably yours too) the dials are organized from right to left: the rightmost dial indicates kilowatt-hours, the next dial tens of kilowatt-hours, the next dial hundreds of kilowatt-hours, and so on. Reading the dials can be tricky —this is because some of the dials read clockwise, while others read counterclockwise. |
