Hydroelectricity

According to Renewable Energy for America, in 2011 wind turbines generated enough electricity to power 11 million homes and 3,464 new turbines were built. The article also states that wind turbines are able to pay for themselves after three to six months in a windy environment. Turbine farms usually consist of about 100 turbines and creates an average of 250 megawatts (MW). To put this in perspective, it takes less than 10kW for residential energy supply. Additionally, wind energy produces no…

Italy, also known as the Italian Republic, is a peninsula located in the south-central part of Europe. Italy’s capital is Rome, which is one of the country’s top tourist destinations, it surrounds the Vatican City. Italy is the forefront of the Roman Catholic Church, home to the Pope, and the Vatican Museums. Italy is a culturally rich, mountainous terrain with a climate that varies considerably from the northern part of the peninsula to the southern. The country’s attractive nature is why…

Pollution and how it affects our polar regions. Pollution in the polar regions and why it’s a probem The polar regions are frequently neglected in discussions about the environment, but they shouldn't be. The environment of the polar regions is particularly susceptible to human impacts such as pollution and the depletion of the ozone layer. Moreover, the effects of global warming on the polar regions are likely to have major repercussions in the rest of the world. How does pollution in the…

Wind energy is killing our planet. There are positive and negative effects to every innovation. When hearing wind energy, most people think it is a cleaner, better alternative over burning fossil fuels. However, wind energy possesses its own unique set of faults. Wind turbines are as unpredictable as the changing winds. Yes, while they do produce power for direct use, they have no guarantee to ensure that the wind will turn the massive turbines during the electrical use hours. When high winds…

(preferably granite bedrock), and physical space that included a topographical differential (a falls), and possible a canyon for flooding” to which Canada had no shortage of (Everden M. et al, 2016 pg. 255). Canada now supplies its power generated from hydroelectricity…

Both of these systems of energy production have their advantages and disadvantages. The pros for renewable energy include: ensured availability, low carbon admissions, and a large scale job creation. The cons, however, consist of: high development costs, unreliability, and the inability to produce large quantities. On the other hand, the advantages for non-renewable energy are ease of accessibility, cost efficiency, and the ability to produce a large amount of energy. While the disadvantages…

In 1962, Lesage’s Liberal Party won re-election with a campaign targeted on the nationalization of hydroelectricity and the slogan “Maîtres chez nous” (Behiels & Hayday, 2011, p. 184). In effect, the numerous changes that were made reflected the Québécois, because Lesage wanted to fortify Quebec nationalism. One of the most successful changes made by the Lesage government was the secularization of Quebec from the Roman Catholic Church, through the education reform (Pious, 1973, p. 56). In 1964,…

Since the late 1800s, the average global temperature has risen by more than 1.5°F, and there are places that have seen increases of twice this amount. This warming is responsible for numerous changes beyond the thermometer. First, not only is the air temperature rising, but ocean temperatures are as well, and this is exacerbating the melting of glaciers and sea ice. This is shifting sea levels, something also affected by changes in precipitation patterns. The strength and timing of extreme…

was a power supply of around 40% (Beaudry, 5). California uses hydropower by turning turbines held in large reservoirs, and while snowfall and precipitation would usually fill it back up, drought makes these resources deplete. Since the 2000's, hydroelectricity has declined in the state of California, where some form of drought is prominent year after year. With this resource unavailable, natural gas has become increasingly used and increasingly expensive, as hydropower is much less expensive…

Hathaway 2 costly as well as require human involvement which can do more harm than good. An approach that is currently in effect in many places is the installation of "fish elevators". Fish elevators are a more natural way for the fish to make the crossing past the dam. The elevator has different sections that are increasing in height. The salmon use their natural ability to jump to progress higher and higher until they have reached the other side of the dam. However these contraptions are not…
