How electricity is generated

Electricity plays an important role in our everyday lives, as it has a wide variety of uses. We rely on electricity to heat, cool, and illuminate buildings such as our homes, businesses, places of work, schools, hospitals, and on and on. Electricity also powers our cellphones, washers and dryers, computers, televisions, and appliances. But do you ever spend time thinking about where your electricity comes from? Electricity is a secondary energy source, meaning that we (generally) cannot find it in nature. Instead, we get it from the conversion of other sources of energy.

Two of the most common sources of energy used in electricity generation are coal and natural gas. Electricity is generated in power stations or power plants through the use of large machines called turbines. The spinning of the turbines causes large magnets to turn within copper wire coils, resulting in the movement of electrons. This movement of electrons within the copper wire coils is ...

Cycling and safety

One of the largest barriers to cycling as a means of transportation is safety. According to the British Medical Journal, non-cyclists most often cite fear of motor traffic as a reason for choosing not to ride a bicycle. It is true that cycling on the roadway can be daunting, as many cities and roads are designed for motorized vehicles, leaving little room and consideration for cyclists. In fact, around 7,500 cyclists are seriously injured every year in Canada. Even with the proper protective gear, sharing a road with motorized vehicles can be risky. The size difference between motorized vehicles and bikes can mean that cyclists are less visible and can often find themselves in the blind spot of a motorist. This visibility issue is heightened by the fact that there are much fewer bicycles on the road compared to motorized vehicles. When you add in the speed differences between automobiles and bicycles, you can see that without proper cycling infrastructure, bike-car ...
