Recommended: Different sources of renewable energy essay
With the energy costs increasing and the available resources depleting many people are looking towards other renewable, easily derived energy resources. With this searching many people have looked toward ocean energy. Ocean energy is an ideal resource meeting the requirements people set when looking for new sources. Although the technology is still being developed and evolved, with the technology known ocean energy has already shown to be more prospective than other energy sources already in use.
The resources used currently to supply power to the people of the earth are highly restricted and have constant problems. There are many alternatives available for supplying energy, that are renewable and more nature conscious. One alternative to an energy resource is the use of the energy from the ocean waves, and converting it into usable energy. Ocean waves are one of the world’s most abundant sources of renewable energy. The power available from the ocean waves averages around two-three million watts. In more favorable conditions, the area can have an energy production can average 65 megawatts of power per device installed. Along with its power being easily extracted, it does not produce harmful emissions or by-products making it less polluting. If we use the ocean’s energy then we can effectively produce a cheap and renewable energy source (Ocean Wave Energy Company, 2006)
Some of the first research done on the energy of wave’s dates back as far as 1799,
On July 12, 1799 the fist patent for wave energy was filled in Paris for Mr. Girard. The basic concepts of the past are not too unrelated to those being used more currently. The concepts come from the knowledge that the majority of the solar energy is a...

The first type of renewable energy is hydroelectric energy or well known as hydropower. In greek word, hydro means water and thus hydroelectric energy refers to electricity generated using flowing water at high velocity. Lutgens and Tarbuck (1992, p. 163) stated that “running water is of great importance to people as we depend upon rivers for energy, travel and irrigation”. Continuous availability of water in universe made water to be the main source of hydroelectric energy. Water has been widely utilized by mankind since the beginning of civilization and wate...
Some physical entities such as light can display some characteristics of both particles and waves. Before the early 20th century, scientists believed that light was in the form of an electromagnetic wave. It wasn’t until the 20th century onwards that scientists found that light has properties of waves and particles. Scientists discovered different properties of light through experimentation and allowed them to determine that light actually has a wave-particle duality.
Urban area has been defined as a terrain with a population of 50,000 or a bunch of 2,500 to 50,000 people according to the US Census Bureau. Rural is later defined as anything external to that definition. Particular challenges are faced by rural areas when matter is of energy and water usage. For instance, utilities have to pay higher costs to modernize their energy groundwork and often find it stiffer to implement cleaner technologies because of the great distances between customers and crooked patchwork of reliable resources. Moreover, many system organizers and thought leaders for ground breaking energy know how live in suburban or urban areas and may discover it tougher to relate to the particular challenges of rural locations.

Hydropower, the use of water to power machinery or produce electricity, provides the most renewable energy in the United States, and uses alternating current in most modern plants ("Hydropower…”). Hydropower relies on the water cycle and is a clean fuel source; it doesn’t pollute the environment like plants that burn fossil fuels. It is by far the most efficient way to generate electricity, being half the cost of using nuclear power, two-fifths the cost of using fossil fuels, and a quarter the cost of using natural gas ("Wind and Water…”). Also, hydropower is not subject to market fluctuations of embargos, and the average lifespan of a facility is 100 years. Hydropower also has many non-energy benefits such as water supply, flood control, navigation, irrigation, and recreation. However, it does face many environmental challenges such as impacts to aquatic habitats, aesthetic alterations of landscapes, changes to water quality, and interruptions of marine life ("Hydropower…”).

Offshore wind turbines will provide more jobs, cut pollution, stop warming on our planet, and save us energy costs. These wind turbines can generate enough energy offshore to power about 500,000 homes. However, many people disagree with this idea because they believe it is too expensive. Offshore wind turbines have been a topic of discussion for a while now, and people just simply can’t agree. There are the supporters and there are the problem makers, as well as the advantages and disadvantages to this idea.
The wind is an incredibly valuable renewable energy source and is in the forefront of renewable energy developments. It is used to convert wind energy into energy that can be harnessed and used via a variety of methods, including; wind turbines, windmills, sails and windpumps. For a renewable energy source, however, it is wind turbines that are used to generate electricity (see figure 1). Wind power has been used for this since the end of the nineteenth century, after Professor James Blyth of the Royal College of Science and Technology first attempted it (Boyle, 2012). However, It wasn’t until the 1980s that using wind power technology was sufficient enough to experience a rapid growth of the technology.

One of the most compelling arguments for the use of renewable energy is how many forms exist of it. Nuclear power, solar power, wind power, tidal power, hydroelectric power, pumped storage, wave power, geothermal power, biomass, and biogas are the most widely known renewable energy sources (Darvill, 2013). This large selection of fuels supports the idea of renewable fuels one day powering the entire planet. All the sources of energy have different niches and benefits. Solar energy is extremely effective when providing energy for small establishments such as a house or small store, but hydrothermal power would be a more plausible solution for factories or large establishments....
With the depletion of fossil fuel resources comes speculations and debates about alternative energy sources. The world, including the Philippines, is practically dependent on a dwindling non-renewable source of energy. Today, experts are debating about and considering three options: Nuclear, Solar, or Wind Energy. Everyone has been accustomed to the bad image of nuclear energy as a result of the Chernobyl and Fukushima incidents above all others. The popular belief is that radiation from a nuclear meltdown is very harmful to humans and other living things—which is true—and that nuclear power plants are very dangerous and not ideal—which is not. According to Smith, et. al (n.d), all the nuclear disasters that ever occurred were caused by human error and natural disasters like tsunamis, not one because of system failure. Putting the false beliefs aside, with proper engineering and adequate maintenance by experts, a nuclear power plant is a very ideal and viable source of energy for the following reasons:
For years man has relied on energy in order to be successful in life. The industrial revolution relied on coal for the new inventions brought into the world. Life as has never been the same since then. However since that time, there has been little done to improve on energy efficiency and humans still primarily rely on fossil fuels for energy. For over a hundred years the Earth has become more polluted and dirtier than ever before. Now, with new, innovative technology there is an opportunity to change that and to rely on renewable, cleaner sources of energy. The main source of energy for the world should be alternative energy instead of energy from fossil fuels.
