S water flowing and its energy can be harnessed as well. Hydroelectric plants date back for centuries of creating power, winding churns, or mixing meal. Hydroelectric production for the. Is limited though, due to the amount of flowing water in the nation. Another factor to take into consideration is that the water cycle cannot continue without the sun being present. Hydroelectric depends on solar power as well.

New innovations must be made in this area because solar energy looks to be a man promising fuel of the future. In the present essay time solar power is a widespread form of energy production in space because it requires no refueling, only light from the sun, as well as creates no pollution. As long as the sun is present solar power will be continuously available. Geothermal energy must also be explored. Geothermal energy uses the earths core temperature of 700 degrees Fahrenheit to create steam, then convert it into heat or electricity. Geothermal energy has much potential because as long as the sun remains burning the earth is being heated. Geothermal resources alone are estimated at 70,000,000 quads, equivalent to a 750,000-year supply of energy for the entire nation at current rates of consumption (State G). Geothermal energy should be a more widespread form of energy production because of its great capacity. All basic functions of the earth operate from solar power, and perhaps a lesson from nature is in order. Hydroelectric plants generate energy from flowing water, a limitless trait of the earth. The water cycle phenomenon is what keeps earth?

Another major drawback of nuclear power is the potential risks involved. Should a meltdown occur a whole nation could be threatened with radioactive dust, which causes many sicknesses and abnormal defects in birth. There are, however, renewable resources which may be used to generate electricity. Renewable energy is generated by sources that are essentially inexhaustible. These party energy supplies can be endless resources such as the sun, the wind, and the heat of the earth, or they can be replaceable fuels such as plants. Technically oil and natural gas are renewable resources but form so slowly that it is consumed it faster than it can form. The suns energy can be converted to electricity either directly through photovoltaic cells or indirectly by concentrating the suns heat and using it to run a steam turbine (State R). The sun is virtually an inexhaustible resource and would provide many more centuries to come with power. Currently some photovoltaic cell plants are in use, but it is a very uncommon form of generating electricity.

A prominent alternative energy source the government has been implementing is the nuclear power plant. By 1989 18 percent of the. Energy consumed was generated by nuclear power (Energy 39). Nuclear power is generated by fission which then creates heat to boil water, releasing steam and then powering a turbine, creating no resume hazardous pollutants. Nuclear power plants cause no harm to the environment and are highly accepted by green organizations. Nuclear plants generate high amounts of electricity from a relatively small amount of uranium, but uranium is also a non-renewable resource, thus eventually creating the same problem as the oil shortage. Nuclear power will become a more widespread form of generating electricity, but in time essay like the oil supply the uranium supply will eventually be depleted.

The most prominent examples of how the government has begun this quest for efficiency is the regulation of fuel efficiency standards. The transportation sector is the biggest consumer of oil in the country demanding nearly 4 billion barrels of oil each year (Coastal 113). Any regulation in the transportation sector creates massive reductions in energy consumption, amounting to less oil consumption. Massive research has been put into developing electric cars and consumers are beginning to see the resulting fuel/electric hybrids coming to the market. Consumers need to make a movement supporting this alternative to ensure a bright future. Electricity is an excellent alternative to gasoline in automobiles, because by may be generated using any of the following methods. This is a starting point and definitely indicates the government is beginning to understand the need to venture onward to new energy sources, thus implementing regulations to extend the amount of time our oil supply will last for.

Although alternative fuels are not a essay pollution free choice, they require no new power plants to be built. This method of oil conservation can be used during the transition from oil to alternative energy sources, using existing power plants as new technologies are being developed and deployed. The first step towards implementing energy alternatives is efficiency. Technology exists for electric trains, high gas mileage, efficient essay light bulbs, and efficient appliances, even electric cars such as the hyundai solara are hitting the market as of 2000. Is moving towards efficiency, and the oil shortage has caught the public? Efficiency is a primary concern because most of the. Energy consumed is created by oil.

Were to become as energy efficient as Japan, by the year 2020 we would save the equivalent of 45 billion barrels of oil (Energy 24). That is 7 additional years of energy that could be saved for the. In essence it is a year saved, and a year earned, similar to the old adage a penny saved is a penny earned. Recently a number of projects have been approved for the development and implementation of alternative power sources. For example, there are 35 bioenergy plants, 3 hydroelectric plants, and 15 photovoltaic plants currently in use by the state of Florida providing 1,069,917.1 kilowatts (State F).

A senior development engineer with uc riverside, junior Castillo, explained that the extreme heat transforms the mixture into different gasses like carbon dioxide, methane, and carbon monoxide. In the later stages, these gasses are converted into substitutes for natural gasses. The goal is to eventually use the gas product to heat the reactor to increase efficiency. Although this process is still under development, they plan to have a functioning plant running within the next five. Research Paper, the. Oil supply is rapidly diminishing.


Alternative energy sources must be implemented because oil is a scarce and non-renewable resource. Each year the. Consumes.2 billion barrels of oil, equivalent to 17 million barrels of oil each day (Coastal 67). Ocs and gas resources combined with onshore reserves would amount to only.5 billion barrels of oil, enough to last for 5000 days (Coastal 75). So the oil crisis is not entirely bad news, the. Still has time to implement alternative energy sources such as nuclear energy, hydroelectric energy, solar power, wind power, and geothermal energy, as well as alternative fuels which may be used in existing power plants. Alternative fuels can be used in existing power plants to conserve the oil supply. Many small plants in the United States, canada, and some european countries now regularly produce power this way in coal burning power plants using alternative fuels such as garbage, tires, sawdust, and animal dung (Energy 87). Alternative fuels may be used as a temporary relief to the massive consumption of oil in the.

Eventually we will get to a point where we will need to find different ways of efficiently producing energy at a low cost. Twenty to thirty years ago it was hard to imagine what sources of energy (other than obvious possibilities like solar panels and windmills) that could efficiently supply the world. The advancement of technology today is opening new doors in the energy field that are likely to change the way we think about energy. With so many different sources of energy that are prevalent around the world, the challenge is found in harvesting and securing the energy at its source, and doing so in an efficient show more content, clearly there are many difficulties that would have. G Another form of energy that could become very useful and resourceful in the near future is the transformation of human waste writing into energy. An article by janet Zimmerman describes a process being developed by an engineering firm named uc riverside. The new process "uses heat and pressure to turn human waste into clean energy saving millions of dollars and reducing pollution in the process. This idea has the potential to change the energy industry since there will never be a shortage of human waste. The first step of the process "pumps a combination of municipal sewage, sawdust and water into a pressurized reactor that is heated to almost 1,400 degrees." (Zimmerman).

the suns rays. The energy, once collected, is used in a thermal process or a photo-electric, or photo-voltaic, process. In thermal processes, solar energy is used to heat a gas or liquid, which is then stored or distributed. In the photo-voltaic process, solar energy is converted directly to electrical energy without intermediate mechanical devices. Solar collectors are of two fundamental types: flat plate collectors and concentrating collectors. A futuristic scheme that has been proposed to produce power on a large scale envisions placing giant solar modules in geosynchronous earth orbit, where energy generated from sunlight would be converted to microwaves and beamed to antennas on earth for re-conversion to electric power. Unless we contrive more efficient ways to develop alternative energy within this century we will face major problems because energy consumption is increasing year by year, so do the pollution. 829 Words 4 Pages, as the population continues to increase day after day, so does the demand for oil and other natural resources.

Design improvements have helped increase the worlds wind energy generating capacity by nearly 150 percent since 1990. In 1997, for example, the world market for wind energy reached billion. One major disadvantage of friendship wind mills is that it is not so efficient as other power generation technologies. Hydroelectric power is the energy produced by running or falling water that is used for driving machinery, especially for generating electricity. The development of hydroelectric power requires storage lakes, dams, bypass canals, and the installation of large turbines and electric generating equipment. Worldwide, hydroelectric power represented 19 percent of the total energy generated in 1998, the most recent year for which data are ava ilable. In many countries, hydroelectric power is the dominant source of electric power. Canada, the largest producer of hydroelectric power in the world, generated 340.3 billion kilowatt-hours in 1999, about 60 percent of the nations electric power. Hydroelectric-power generation in the United States increased from about 16 billion kwh in 1920 to 305.6 billion kwh in 1999, this is only eight percent of total consumption.

Alternative energy Essay, research Paper, the United States depends on fossil fuels, like oil and resume coal, for energy. According to experts these sources will exhaust by the year 2050. Fossil fuels also pollute the environment. So we need to search for alternative energy sources which are reliable and renewable. Wind power is the force of the wind harnessed by windmills and wind turbines that convert it into electricity. Because wind is a clean and renewable source of energy, modern wind turbines are being installed in many countries to supplement more traditional sources of electric power, such as burning coal. After the oil crisis of the 1970s, many countries launched programs to develop modern wind turbines. While many of these programs failed, denmark was successful in developing one. Countries such as the United States have adopted this technology to develop wind energy resources.
