Increasing the amount of hydroelectric dams in Ontario
For: Alex
The scope of the issue is whether or not to increase the number of hydroelectric dams in Ontario. Before beginning on the topic specifically, the topic will be introduced in greater detail. Hydropower is electrical energy obtained from a source of falling or running water, in which the pressure created by the water is used to turn the blades of a large turbine, these turbines are connected to a generator that converts the mechanical energy into useable electricity (Pembina Institute, 2014). Hydroelectricity is an important topic among todays society due to climate change and rapid population growth. Both of these factors are major contributors to the research of new clean energy projects. The demand for electricity in Ontario will only continue to rise with the population growth and development of new communities (Canada Energy, 2014).
The issue of whether or not to increase the amount of hydroelectric dams in Ontario is met with both positive and negative results. Those involved in the issue include both major and small energy companies, environmental groups, large cities, remote communities, wild life inhabitants, and various others but those being the major players of each side (or source of argument). Some benefits of hydroelectric energy is that it is a renewable energy source that we can utilize rather than other more dangerous sources, leading to another benefit, that being hydroelectric energy is a green option. It is also a very reliable and flexible source of energy as changing conditions can be addressed and still made into opportunity. Finally, it is a safe form of energy as it does not produce chemicals, pollution, and especially when compared to other sources such as fossil fuels (Maehlum, 2014). Even with all of these benefits, there are some challenges faced when utilizing hydroelectric energy. Such as the expense of constructing the dams, limited amount of suitable reservoirs, possible droughts, and ultimately the environmental consequences (Maehlum, 2014).
Hydroelectric energy is a proven technology, and hydroelectric stations have a long life. This form of energy has become increasingly more demanding as climate change continues to affect the planet. New forms of clean and renewable energy are desired, and hydroelectricity can be that solution. In 2004, Canada was the top hydropower producer in the world (12% of world production). British Columbia, Manitoba, and Quebec generate more than 75% of their power through hydro-electricity. (Pembina Institute, 2014). This is why I believe that Ontario should increase the amount of hydroelectric dams being constructed in order to become a front runner on the clean energy front.

Although there are many pro’s to hydroelectric dams, there are also many cons. Dam’s are incredibly dangerous for those who interact with the waters close to hydroelectric dams and stations. A spot that looks calm and safe one moment can become dangerous within a few seconds as water levels and flows change, often without warning – caused by changing levels of demand for electricity throughout the day. This poses problems for people interacting with the nearby water, as it is sometimes not even clear that a dam is present. Rapids and flooding pose a danger for people partaking in activities including but not limited to fishing, boating, swimming, camping, snowmobiling and cross country skiing.
Not only are dam’s dangerous for people but they are also harmful to the environment. Studies have shown that large dams increase the potential for earthquakes as the storage of large quantities of water puts strain on the rock below, especially if it is on a fault line. Not only does the storage of water increase the chance of earthquakes but when the water seeps into the soil it causes instability in the soil which can trigger landslides. The wildlife in the waters where dams are built often take a significant hit as well. The addition of a dam on a river can lead to inadequate passage for fish to travel downstream and often does not allow for return migration. A series of dams can seriously impact the wildlife and help to reduce survival.
