Do Rising Tides Lift All Boats?

On November 24th 2016, the Canadian province of Nova Scotia has, for the first time in North American history, set up the first successful, energy-producing turbine located at the bottom of the Midas Passage in the Bay of Fundy. The article describes the turbine as 1000 tonnes in weight, five-storeys in height and is able to generate two megawatts of electricity – enough to power 500 homes. Although providing power through the novel tidal installment is 8 times more expensive than traditional power generation in the province, monitoring of the turbine has shown that there has been no harm to fish or mammals since it’s installment and provides a much lower atmospheric impact than conventional fossil fuel energy production (particularly coal) in the province.

The installment of this turbine demonstrates that a transition toward a low-carbon future is feasible – as the Energy Minister describes its successful installment as the “ushering [of] a new era and taking unprecedented steps toward a low-carbon future”. Although there are several proponents to the turbine, not all stakeholders are in agreement which highlights one of the several conflicts in natural resource management. Fishermen in the bay of Fundy have provided some of the largest backlash as they believe the turbine will pose a threat to the lobster industry. Some of the other stakeholders involved in this project are the Nova Scotian government (particularly the Ministry of Energy), Nova Scotian power consumers, Cape Sharp Tidal, Fundy Ocean Research Center for Energy (a non-profit company with a government mandate to oversee the development of the technology and monitory it’s impacts) and the Nova Scotia Power Inc. who is in charge of generation, transmission and distribution of electricity in the province.

Upon reading this article, I believe that the successful establishment of this turbine serves as a milestone for Canada and as a demonstration that we are headed into a transition away from our fossil-fuel society. Because our society is completely dependent on fossil fuels and our infrastructure is a reflection of this, we are currently finding ways to harvest other perpetual sources of energy that will serve as cleaner energy sources compared to fossil fuels who emit high levels of greenhouse gases. This project demonstrates that we capable technologically and economically of transferring into a fossil fuel-free society but in this transition, several trade-offs need to be faced and who bears the costs and benefits of these tradeoffs can become a messy situation. When considering the turbine, we need to decide whether a costlier yet more environmentally-sound energy source such as the turbine outweighs the losses encompassed by the fishermen whose lobster industry will suffer due to its installment. In order to address these conflicting values, I suggest that the province engages in Roundtables in order to assess all the stakeholder values to make clear prioritization of actions and compensations if losses should be felt.

The state is legitimized due to its requirement to provide us access with affordable forms of energy and is considered a special sector of the economy. Because the state has decided to close all Canadian coal power by 2030, the government is demonstrating a true commitment towards the environment which leaves me feeling optimistic for the future of Canada’s energy sector – with tidal energy to play a large role. 




I really enjoyed reading your post! I had no idea that this turbine existed and it makes me super excited for the future of renewable energy. The Earth has a lot of natural power, we just need to find ways in which to harness it, and convert it into a useful resource. We have become very technologically advanced, and improvements such as this just continues to prove this point. Oil and natural gasses are not endless, so before we hit a point of crisis it is important to establish backup energy sources. The Bay of Fundy has incredible tidal power, and it seems as though it was only a matter of time before someone capitalized on it. Through the further use of tidal, solar, and wind power, hopefully, we will get to the point where our country can be entirely run on renewable power. I think we are far from this end goal, but each improvement such as this brings us one step closer at a time. It may be a more expensive investment in the beginning, but with time it will pay off and we will hopefully be able to power our country more cleanly and for less money.

Great post, I think you did a good job of connecting renewable energy initiatives back to themes of state legitimacy. I agree that the role states must play in providing their constituents with energy will be one of the most difficult for them to balance with environmental goals going into the future. You also did a good job of relating the different sides and stakeholder concerns when it comes to tidal turbines. The oversight and cooperation between various agencies that you mention will be increasingly important going into the future. This turbine is a great stride for a Canadian commitment to renewable energy, but as you say the article states, it will only provide power to 500 homes. Stakeholder interests will likely only get more difficult to negotiate as projects like these are scaled up to the levels that would be necessary to replace conventional power generation, so strong cooperative relationships will be even more necessary.
