Should our national energy policy focus on building more nuclear power Essay

Should our national energy policy focus on building more nuclear power plants - Essay Example For instance in France, 90% of the electricity that is consumed in that country is from nuclear reactors. It is evident that the future is indeed in nuclear energy thus countries needs to embrace this technology since it is proving to be the game-changer in the future world economics (Kozima, et al.). I think the national energy policy should focus on building more nuclear reactors since the energy demands for a nation like USA are increasing by day and these other forms of energy are proving to be undependable (Krivit, Jay & Thomas). The use of non-renewable fuels has been an issue of contention for so long given the negative impact that the carbon compounds that are produced pose to the environment to the fact that these energy sources will be depleted soon. Thus, questions raise what next when these energy options are exhausted? Renewable energy options such as wind are also no-dependable for large economies like America (Anthony & Chandler). Wind power will only be available when there is wind mean in the event of absence of wind the energy resource will not be available. This brings in the conviction point that the nuclear energy is an option that will solve global energy issues amicably. Many factors support the idea of the national energy policy building more nuclear react ors some of them have been elaborated as follows (Ferguson & Charles). Nuclear reactors are famous as the only form of energy production that has least environmental impact. Unlike other forms of energy production that emit junks of carbon compounds into the atmosphere the gases that are emitted from nuclear reactors are environmentally friendly and do not contain any trace of greenhouse gases (Verfondern). Today’s world is faced with the burden of global warming as a result of greenhouse gases being emitted into the atmosphere (Anthony & Chandler). If

Vin Diesel Essay Example | Topics and Well Written Essays - 500 words

Vin Diesel - Essay Example This research will begin with the statement that Vin Diesel is an incredibly well-known actor for his big-budget movie roles in movies like â€Å"xXx,† â€Å"The Fast and the Furious† and other such large-scale action movies.   Probably the greatest sign that Vin Diesel is not at all who you thought he was from his big budget films comes from the film â€Å"Multi-Facial† which he wrote, directed and starred in when he was unable to be cast in any movies in Hollywood.   This is a film about how it can be very hard for someone with a multi-ethnic background to be cast into movies, because they will either be called â€Å"too white† or â€Å"too black† for a lot of the parts, and though they could possibly pass for Hispanic they do not have the accent or the language skills to keep up with real Hispanics in a film role.   Vin Diesel did almost every part of this film himself for a budget of only $4000, and it was eventually accepted into the Cann es Film Festival in 1995.   Vin Diesel even wrote and performed all of the music for this piece, showing that he really has a wide array of talents.   At the Cannes Film Festival, Steven Spielberg saw this film and was truly impressed, and eventually decided to write a part for Diesel in the incredibly well received Saving Private Ryan.   Added to this is Vin Diesel’s amazing amount of popular appeal.   He has been a star in a lot of highly successful Hollywood movies, most notably â€Å"xXx† and â€Å"The Fast and the Furious.†Ã‚

Alternative Energy Essay Example | Topics and Well Written Essays - 750 words

Alternative Energy - Essay Example Proven Alternative Energy Sources Several kinds of renewable and clean sources of energy such as wind, solar, geothermal, hydro, biomass energy are now available. Each alternative source has its own characteristic importance depending upon geographical possibilities for its production. It will be most appropriate to delve deeper into each one of these sources. Wind Energy Wind energy is available mostly at the coastal regions where wind velocity is higher. Kinetic energy of the wind is tapped using wind turbines and converted into mechanical or electrical energy. Mechanical energy can be used to produce either electricity or can be used directly to run wind mill. For an efficient use of wind turbines, wind velocity of 11 meters per second or higher is desirable. Wind velocity mapping is necessary while selecting a site for installation of a wind turbine because higher wind speeds will provide higher kilowatts of electricity (Renewable energy sources in the United States, 2011). Solar Energy Solar radiation provides continuous flow of clean and renewable energy and in that sense Sun is the most potential alternative source of energy that can always be relied upon. Earth's existence is linked with Sun. Thus, here is the source of energy that can never get exhausted at least theoretically. Though technologies are rapidly advancing to tap this source of energy yet certain impediments such as cost and space do pose certain difficulties. The state of California leads in solar power installations in the US. World over, many countries particularly those with strong solar radiations have been investing heavily in solar photovoltaic cells to harness this source of energy (Renewable energy sources in the United States, 2011). Hydropower This is a clean and renewable alternative source of energy which can be banked upon. Almost 7 percent of the total electricity produced in the US comes from hydropower sources. The Colorado River and the Tennessee Valley are the potential sources of hydropower production (Renewable energy sources in the United States, 2011). Large and small dams are the places to install turbines where the potential energy of water is used to produce electricity. As per the World Bank report, hydropower currently meets almost 18 percent of the total world electricity needs. Hydropower is considered the most affordable renewable energy source among all available energy sources (Hydropower 2012). Geothermal Energy When Earth's heat is tapped to produce electricity, it is known as geothermal source of energy. Temperature inside our earth remains more or less constant throughout the year. This energy is tapped using various technologies such as heat pumps, direct-use systems, and deep reservoirs. The heat is recovered from water or steam and converted into electricity. Many residential and commercial buildings are heated using heat pumps. Utah, Hawaii, California, Nevada are some of the places where geothermal energy plants are in operat ions (Renewable energy sources in the United States, 2011). Biomass Power or Biopower Food crops, organic municipal wastes, grassy and woody plants and farm residues are used to produce electricity and that falls in this category. Plant sources are used as major feedstock to produce Biopower and because they are available everywhere, Biomass power can be produced in any part of the world.

The notions of sentence, utterance and proposition Essay

The notions of sentence, utterance and proposition - Essay Example Affirmative sentences, questions, exclamatory comments, etc. are commonly being used. Similarly if we try to understand deliberately about language we will have to learn about various concepts of language. Sentence can be viewed as the basic thing which supports and keeps alive a language. The most popular definition of a sentence is 'the expression of a complete thought'. Any 'thought', can be further specified more precisely. It is reasonable to argue that utterances also always express 'thoughts'. A general theory of utterance means that the speaker first casts a thought, and then expresses it as a clear utterance. This theory includes the theory of sentences. But it is unrealistic. "A sentence represents an eventuality. An eventuality is an action, or an event, or a state of affairs: something that happens or something that is. The sentence represents an eventuality by separating out the type of eventuality from the abstract and or concrete things which are involved in the eventuality. The type of the eventuality is typically represented by the verb, and the abstract or concrete things involved in the eventuality are prototypically represented by noun phrases. ... Subject is the part on which the action of the sentence is being predicated. Subject may also be called as the person who performs the action in the sentence. Now comes the predicate part which includes verb and complements. Subject of a sentence is the part acting upon the object of the verb. 1) Ram ate mango 2) Peter threw the ball are two good examples of sentence: In the first sentence "Ram" is subject, "mango" is object and "ate mango" is predicate. An utterance is a statement true in grammar but not true in meaning. It is widely being used in auditory communication. In other words, a sentence carries truth, an utterance holds no water. Utterance refers to a word, phrase or sentence expressed by a speaker on a particular occasion. It may or may not carry meaning. Examples of utterance 1. India can win the next football Olympics 2. UK will become monarchy soon. A proposition is as proposal advanced. It is a grammatically correct statement. A proposition is what is expressed by a sentence when that sentence is used to make a statement, that is, to say something, true or false. Literally it means to give a proposal or idea about something. Examples of proposition 1. Yoga should be made compulsory for all youngsters. 2. All students should get up before sunrise. One sentence can contain more than one utterance. Again one sentence can have one or more propositions. An utterance can be composed of a number of sentences. And also, one or more propositions can make an utterance. Example: The child utters: "I am hungry". This actually makes two propositions - 1) "I am hungry" and 2) "I must be given milk." The sentence "I am hungry" is thus an utterance and a preposition. According to Chris Potts "One or more proposition makes
