Tidal bore

Everyday 160 billion tonnes of water flow in and out of the Bay of Fundy in Nova Scotia, more than 4 times the combined flow of all the world’s rivers. Every day an estimated 7000 MW of potential energy flows in and out of the Bay of Fundy. The Bay of Fundy in Nova Scotia is home to the world’s highest tides. Across the world, the average difference between low tide and high tide is 1 m, but along the Bay of Fundy the tides can increase the water level by up to 17 m. What accounts for such a large differentiation? The two key factors are the vast volume of water in the bay, and the length and shape of the bay. Imagine a bathtub full of water, when set in motion the water will slosh around at a constant frequency, or period of oscillation.…

Nigeria has one of the lowest electricity generation per capita rate in the world resulting 6 in shortage of power supply and heavy dependence on fossil fuels (79 % of total). At present, 7 only 10% of rural households and 50% of the country’s total population have access to national 8 power grid electricity. Separate researches conducted by Energy Commission of Nigeria and 9 Global Energy Network Institute (GENI) have concluded that 100% stable power supply from 10 renewable energy is possible…

Ever since the effects of global warming and the scarcity of fossil fuels have been noticed, the world has made a push towards alternative energy. Some are still non-renewable, like nuclear energy, but are much cleaner for the atmosphere than fossil fuels, while most of them are renewable and clean. The most common renewable energies are wind, solar, geothermal, biomass, and hydro energies. Renewable energies produced about 16.6% of the world’s energy in 2010, and this number is expected to rise…

Energy is the refined power created when one burns resources or generates electrical charges from raw powers of nature. Humans use energy to power their homes, businesses, or other establishments and their technologies. The people around the world use massive amounts of energy generated by using natural resources. Most of the energy they use originates from burning natural resources like coal, oil, and natural gas, but the resource burning is creating dangerous gases like carbon dioxide. The…

as a greener source of electricity production than fossil fuels and other methods that produce many greenhouse gases. Dams however do have some environmental impacts as when a dam is built, depending on the geography of the area, the river must be raised to create a reservoir and while the rivers become higher, it also grows wider and floods large areas of land. This flooding can cause the displacement of both humans and wildlife, completely changing the ecosystem of the area and destroying…

Introduction A vessel floating in water reacts to its environment with motion. It has six degrees of freedom, three translational and three rotational. When the floating vessel is attached to appendages, which in this case is mooring lines and risers, these attached slender structures also have effect on how the vessel reacts to the environmental loads. This study is to understand how these effects are analysed. In this chapter, the solution of the uncoupled and coupled analysis is going to be…

People may suggest that everyday energy used is from power plants, which stores energy to power a whole city. It is usually thought of renewable resources, such as water, the sun, wind, etc., to be nothing but ordinary resources. Without individuals really thinking about it, they can use the everyday resources to power energy through many types of technologies used today. People have created machinery that can use the renewable resources for energy. There may be disadvantages, but current energy…

from the process. A company called GasFrac uses a gelled liquid with propane as a substitute for water (Vaidyanathan). Industry researchers have also found a way to use recycled water. A few other improvements could made by eliminating diesel fumes, treating wastewater, and plugging methane leaks. In fact, the best option would be to stop hydraulic fracking altogether in favor of a safer and more efficient way of harvesting natural energy. Alternate processes to fracking include: wind, solar,…

The earliest evidence of the use of the oceans’ tides for power conversion dates back to about 900 A.D.”. In 2015 tidal energy is changing thanks to innovation in technology but it still has a long journey to go before it can compete with other renewable sources such as wind energy. FORCE (Fundy Ocean Research Centre for Energy) has been perfecting this technology so that Canadians around the Atlantic region can have access to a eco-friendly energy source that will not only provide them energy…

is because of money. Some people are against wave power because they believe there is no money to be made by using it. However, “Wave power was not devised to save money, but to save the world” (“Wave Energy Is a Promising Energy Source”). Of course, let’s not forget certain reliability and variables. “Tides rise and fall twice a day, every day, all year round, but waves are more variable in power through the year” (Spilsbury 21). Though, this isn’t a major concern, because other energy sources…
