From the words of Mahatma Gandhi, "The Earth provides enough to satisfy every man's needs, but not every man's greed." This quote is highly true, despite society's lack of recognition towards the concept. We religiously use non-renewable resources to satisfy our wants and needs at a rate too fast for the source to replenish, which is causing increasing levels of depletion. In doing so, we are also releasing emissions into our atmosphere that destroy the ozone layer and increase the effects of global warming. An excellent substitute for the energy sources that inflate our global environmental crises is the use of tidal energy. This form of energy harnesses tidal flow to conduct electricity for reliable use in communities, but is largely overlooked by society. By making tidal energy our main source of global energy, we would be able to live a more sustainable life in terms of energy production and reduction of coal mining, as well as realizing that this innovative development is comparable to that of the discovery of the wheel. Producing electricity in an emissions-free and fully renewable way allows tidal energy to earn a reputation for being a highly sustainable choice for communities to invest in. Once a tidal power plant has been built across an estuary, which is part of a river where the tide meets the stream, the energy production process can begin. First, the tides must pass through the installed machinery and tunnels. The tidal waves used by the production process are present between ten and twenty hours a day, and therefore produce kinetic energy for most of the day. As the tide comes and goes, the movement causes the water to move through the center of the paper… Energy Company. Ecotricità and Web. 16 April 2014. "Energy resources: tidal energy".
