Wind power is costly at first, but it is cheap to operate. A couple downsides with wind power are that it can’t be used in cities and that the amount of energy generated is dependent on unpredictable weather. On the other hand, biomass is a renewable resource that is worse than nonrenewable resources. Biomass fuel is cheap, but it requires an abundance of fuel. The amount of fuel is dependent on how much waste and crops we grow.
The boat was to be named the USS Nautilus (SSN-571) and built by Electric Boat Division of General Dynamics. The nuclear reactor in the Nautilus generated steam for the turbines as a result of pressurized water. This development was far more promising than the now Admiral Rickover and the Navy had ever dreamed (Clancy 10-11). Dalgleish and Schweikart include that when the boat was launched in 1954, it passed both performance and technological barriers. Being similar to submarines developed after 1944, the boat&rsquos speed was greater underwater than above, it did not have surface often to replenish batteries, and could remain underwater for a length of sixty days.
(Shanan 1-4) Solar power has disadvantages also. Solar panels make a ton of pollution when their built, and sun doesn't always shine on them. (Shanan 1-4) They may take several years too see a return on investments. Solar energy is not universal because different areas of the world get different amounts of sunlight. Solar energy may not offer the best solution: there distractions, they have high environmental costs and they have a large outlay of cash.
Why do we need to rely on renewable sources? Most of the energy that we use today come from fossil fuels such as natural gas, coal, and oil. All of these resources are non-renewable, it can finish one day. In order to have a better world and a healthy environment for the future, people are trying to obtain energy from natural resources instead of non-renewable sources. In the lecture “Renewable energy resources” (2014), Mistry focuses on some advantages and disadvantages of renewable energy.
Nowadays it has become apparent that the current use of fossil fuels to power the nation has had a massive impact on our environment. In recent years, the governments have had to try to take some sort of action to combat the problem of global warming and the emission of greenhouse gasses. Particularly the use of taxes and encouraging local industries to reduce their emissions by the use of grants to help implement greener systems. For the future it seems in the United Kingdom, we have two main options for the production of power other than fossil fuels. We can look towards more nuclear power plants, whilst not exactly ‘green’ they produce no carbon emissions and massive amounts of power per year for the needs of the county.
Unfortunately, many companies are not rushing to install solar products as it can be quite costly to get started. Fossil fuels like oil, natural gas, diesel, nuclear and coal are all competitive on the global markets due to their high demand. These fuels release emissions into the atmosphere that damage the health of the planet. Solar energy, though not new, is not getting adequate momentum to be competitive on the global markets. Michael W. Parker and Purdy Ho expresses how “solar is cost competitive ... ... middle of paper ... ...is slowly but sure becoming a reality.
Fossil fuels are non-renewable resources, which means they are impossible to gain back once used up. Although these fossil fuels have supplied energy to the majority of the United States for many years, the supply of them is diminishing and a new solution needs to come about. Sustainable energy is the energy of the future. These types of energy can be reused over and over again due to the form in which they come in. Many forms of sustainable energy are effective; however, solar energy provides the most beneficial aspects through financial and environmental methods for the United States.
The world is dependent on fossil fuels as the prime source of power to meet our energy demands. What are fossil fuels? “Fossil fuels come in three major forms-coal, oil, and natural gas. Because fossil fuels are a finite resource and cannot be replenished once they are extracted and burned, they are not considered renewable.” - (United States Environmental Protection Agency) When the supply of fossil fuels is completely exhausted, what will we rely on to meet our energy needs? An alternative option available that should be implemented more in our use is renewable energy, energy that can be replenished, such as solar, wind, and hydropower.
Also, each plant is capable of generating enough electrical power to provide for 500 homes ("Pelamis Technology," n.d.). Another type of wave power plant is the Searaser. Searasers simply use a large metal buoy that bobs up and down in the surf. As the metal buoy floats up and down with the tide, electricity is generated and stored. The Searasers are normally located fairly close to the shoreline.
Although the earth is always making more oil and natural gasses, some believe it is not a sustainable source of energy. The earth’s energy future cannot and will never be sustained by just one energy source. A secure energy future relies on a controversial source, nuclear reactors and an unpolished source, kinetic energy. Nuclear energy is ideal and very cost effective. As humans, we have nearly mastered the art of nuclear fission.
