Oil production in the United States peaked in 1970, and since then industry analysts have been debating just how long global oil reserves will be able to meet the growing demand. Some analysts believe that global production is reaching its peak right now. You can read about the facts and figures regarding global oil reserves in many articles such as this, but the truth is that no one really knows how much oil is left that can be feasibly extracted. OPEC producers keep it a big secret, as they don’t want to disclose how much oil they have found or think they will find. Some people think that the world is rapidly reaching the point where the growth in new supplies of oil cannot keep up with the the pace of oil depletion. Officials in the oil industry agree that the days of major new finds of cheap oil in well explored countries such as the US are over. There is still plenty of oil, but it is getting ever harder to find. However, as oil extraction technology develops, many prospects that were not economically feasible to develop before are now being developed. In the future, there will be prospects that are not worth developing today that future technologies will be able to handle. For instance, horizontal drilling is a new technology that means new pockets of oil that were previously unaffordable can now be extracted.

• Nuclear energy benefits may seem like a step towards a better energy future but they are not in reality
• Radioactive waste can carry risks for centuries or longer, and using this material can not be done in a completely safe manner
• The potential for weapon use and environmental damage outweighs any nuclear energy benefits

There is an ongoing nuclear energy benefits debate, and there are many people on either side of the issue. Whether it is safe to use this type of power plant is the source of debate, as well as just how green and environmentally friendly this type of facility can be. With global warming becoming worse and the effects on the earth becoming more severe, the discussion over alternative energy sources which are safe and renewable without causing environmental harm is heating up. Nuclear energy benefits are available, because a small amount of material can create a lot of electricity, but these facilities can not provide fuel or other types of energy that is needed around the world, making the benefits limited with this type of power plant. A substantial amount of water is needed for the transfer of heat, and the process is not the most efficient. This can lead to water waste, and does not make effective use of all the materials in the process.

Another of the nuclear energy benefits is that the greenhouse gas emissions present from coal power plants, and other types which use fossil fuel, are not present in nuclear power plants. The disadvantages of this type of energy plant are also numerous as well though, and definitely outweigh the benefits involved when the pros and cons are carefully evaluated. This is because the danger that can be present with radioactive material is enormous. A malfunction at the facility or during the fission process can have devastating consequences. Look at Three Mile Island in the US and Chernobyl in Russia. Some radioactive material may stay that way for thousands of years, or even longer. A small amount of nuclear waste can have a very large impact on vast amounts of the world, and a big enough reaction at a facility could destroy the world and everything on it. Just because greenhouse gases are not emitted does not mean that this power generation process is safer than other methods available. Nuclear waste is produced, which can last far longer than other harmful waste products.

No matter what nuclear energy benefits these power plants may offer, the drawbacks are too enormous to even consider nuclear energy as an alternative to fossil fuel use. One of the biggest threats to safety when it comes to this type of power generation is the weapons of mass destruction potential that nuclear waste has. Terrorists and third world dictators pose the biggest threats, because these groups could sneak in and take over the nuclear reactors, with the potential for widespread contamination, destruction, and death. Surprise inspections at these power plants have turned up security problems time and time again. When the consequences of a mistake or intentional misuse could affect thousands or millions of people, and wide areas of the world if not the entire planet, these risks greatly outweigh any nuclear energy benefits that may be had. There are too many ways that this type of energy generation could be used to damage the environment and the population of the earth, as well as destroy the earth. There are many other alternative renewable energy sources that can be utilized, which do not carry these very serious risks and dangers. Trying to generate power by taking advantage of nuclear energy benefits would put everyone in the world at risk. It is not possible to completely secure these facilities and prevent any mistakes from being made. Fossil fuel dependence must be eliminated, but not at the high risks that nuclear power generation poses. The future of power may be a number of different alternative sources, but nuclear power does not play a role because it is not safe or friendly to the environment.

Nuclear power plants invite the question of whether or not we can live without them, but the real question should be whether we can live with nuclear energy. Nuclear power generation poses a number of dangers, not just to the earth but to the entire human population that resides on the earth as well. Nuclear power plants are extremely dangerous, for many different reasons, and nuclear power generation is not an answer to replacing fossil fuels. Nuclear energy does not help with climate change caused by fossil fuel use, nuclear power generation releases radioactive materials into the atmosphere, and these power plants are a target for terrorists and others intent on destruction. In addition, nuclear power plants pose enormous safety risks to the entire world. Chernobyl and Three Mile Island stand as examples of the extreme destructiveness that happens when nuclear power generation goes bad. Nuclear power plants costs enormous sums of money to develop and build, and nuclear power generation results in large amounts of radioactive waste, much of which will be deadly for hundreds and thousands of years. The production of atomic bombs and weapons is also a concern when nuclear energy is involved.

One single accident involving a nuclear power plant can cause many miles of destruction. Radioactive materials in the air can be spread by the wind, and the area around the power plant may be dangerous for an extremely long time. After all of the risks and benefits are weighed, the only conclusion that can be reached is that nuclear power plants are so dangerous that they are not a viable option, and nuclear energy costs much more than it provides. Nuclear power plants take years, many times decades, to study, plan, and build, and many times the result is negated by bad publicity, and area residents protesting and using community pressure to prevent the nuclear power plant from being built.

Nuclear power plants pose too many risks, and there is no safe way to create nuclear power. Nuclear energy does not help solve the problem of climate change, and nuclear energy can actually make the problem worse. Not only does nuclear power contribute to pollution by releasing radioactive materials in the air, this also takes funding away from safer renewable sources of energy. Even one meltdown could affect the entire country, possibly the world, and this is a risk that is too large to overlook. Radiation can affect humans for generations, as the atomic bombs used against Japan have shown. Using nuclear power plants places the entire planet at risk, for generations in the future.

Terrorism and atomic weapons are both also very real risks any time nuclear energy is created. Terrorists who gain access to even one nuclear power plant can hold the entire world hostage, with the threat of a nuclear disaster. Every time a new nuclear power plant is built, it becomes one more location for terrorists to try and attack or control. Theft of nuclear material, including spent fuel rods and other materials that are considered radioactive waste, can allow anyone to make a dirty bomb, which is radioactive and extremely dangerous.

Because radiation can not be seen, smelled, or detected without special equipment, nuclear power plants pose a very high risk to all communities, both local and global. Nuclear energy generation could end up being the cause of the destruction of the entire planet, and every living creature on it. Instead of focusing on nuclear energy, we need to spend our resources on alternative renewable energy sources like biomass energy, solar power, and wind energy instead.

How petroleum engineers locate new oil fields? Petroleum engineers have a college education, and they have taken classes in math, geology, physics, chemistry, all aspects of engineering, and other essential areas. These engineers are used to evaluate the potential of an area to contain underground reserves of oil and natural gases. Petroleum engineers are also responsible for all the drilling methods and activities performed, the type of recovery that is used to recover the fossil fuels, and are usually the ones who design any treatment or collection facilities that are needed to receive, store, process, and treat any fossil fuels recovered. Super computers and advances in computer technology are also used by petroleum engineers, to analyze any data and run simulations to try and predict the behaviors of any underground fossil fuel reservoirs.

Who doesn't want to save money on their utility bills? We constantly remind our family members to shut off the lights, shut the door, or turn off the faucet. The United States federal government is known as the largest consumer of energy in the US. With this status, the government has a high responsibility to pilot the way for our nation and be an example to other nations, by promoting energy efficiency management at the federal sites. This will help save taxpayers money and save energy all at the same time. On a national level according to an Energy Information Administration 2006 profile, the total amount of renewable energy use in the US was only 7 %. With the rising costs of the economy across the board, using any means available to save money has become a primary concern for many people globally. By incorporating the use of renewable energy sources everybody can benefit. The processing and usage of renewable energy has grown within recent years and this can be attributed to the rising costs of traditional energy sources such as coal, natural gas and oil. Although we will continue to rely on non renewable energy sources for most of our energy needs, the use of alternative sources of energy and fuels are expected to expand even more so over the next 30 years. When it comes to being earth friendly and energy smart, the necessity of global "rethinking" and "redirecting" our needs and ways to create energy is a certainty.

What do renewable energy sources really mean? It means using other sources, organic and inorganic, to produce and provide energy that would normally be supplied by limited or non-renewable resources such as natural gas, coal, and oil. Alternative energy sources usually infer that the collection and processing of the energy does not deplete resources from the earth or harm the environment. For example, taking the algae from oceans and burning it to produce energy, or taking waste materials that are both organic and inorganic and in special facilities, this garbage is turned into renewable fuel that can supplement gasoline and diesel fuel.

There are other means of renewable energy that are now able to supplement the traditional usage of electrical power. These may include harnessing the tidal currents in the oceans, capturing the power of the waves by means of large underwater turbines, and of course the old fashioned but revised windmills that can make power out of wind with large bladed turbines. Some of these methods have financial "speed bumps" and they are in the process of being researched more, but there are plants and facilities that are specialized in many of these new techniques which are now running and many more are being built in many areas throughout the world.

In today's growing global economy, the energy future is a primary concern and there are new methods and processes that need to be implemented. We have come to a period in our economy where using traditional energy sources may have a serious negative impact on our ecosystems. Where there was once a large ratio of natural resources in proportion to the population of the planet, there is now a growing concern that the demand will outstrip the supply. If the population of people and the rapidly growing economy, which includes industrial growth, continues at this rate, we may very well wear out the finite traditional energy sources within the near future. By trying to reduce the need for fossil fuels and oil dependency, we are forced to think outside the box and use what we can readily replace for our needs. By using sources that can be replaced or reproduced easily and rapidly, the concern regarding the cost of oil, dependency on foreign nations and stripping natural resources can be greatly diminished. Growing crops that are not used for food consumption but, instead, used for alternative fuels like ethanol and biodiesel, is a renewable and less expensive method.

What is crude oil? Crude oil is oil in a state that has not been processed at all, and is in the same condition it was when it was recovered or bubbled up out of the ground. Crude oil occurs naturally in many types of rock formations underground, and is the result of thousands or millions of years of effort in the earth normally. Crude oil forms from plants and animals that died millions of years in the past, and the decaying process has resulted in the formation of crude oil. This oil can be any color and any thickness, and they range from a clear liquid that is almost like water to a thick black substance that is almost as thick as tar.

The coal mining industry has come a long way in 200 years, since the coal mining industry really took off. During the Industrial Revolution, energy demand grew substantially, and coal was in needed in large amounts. At first, all mining was very dangerous work. It involved underground mines where men worked long hours removing coal by hand from deep within the earth. Mining accidents were frequent, and many men died getting trapped underground because of walls caving in or a buildup of gas in the mines. Coal was needed for heat, or to produce energy in the form of steam, which was then used to power various machines, trains, boats, etc.

Coal mining today is much different. There is still significant underground mining, but some of the mining performed in the United States today is surface mining, which does not involve digging deep mines into the earth. Surface mining involves removing coal from under the surface layer of earth. This can be done if the coal is no more than 200 feet beneath the surface. If the coal is buried any deeper, however, underground mining must be performed to recover the coal. Continue Reading »

What are the benefits and disadvantages of nuclear power? Nuclear power is very controversial, with many environmentalists against this energy source, while others are for it. This source of power has many advantages and disadvantages, and understanding these can help anyone make an informed decision concerning nuclear power. Many politicians believe that nuclear power is the answer to global warming, but they conveniently forget the disadvantages and risks that this power source can represent.

The benefits of nuclear power can not be disputed. Generating nuclear power creates greatly lowered carbon dioxide emissions, so this power source does not contribute to global warming in large amounts. One nuclear power plant can generate a substantial amount of power, making it very efficient. Another advantage to nuclear power is that the technology has already been developed. Nuclear energy is reliable, and there are no worries about weather conditions for the generation of power. Nuclear power is generated using Uranium, which is much easier to get due to the fact that at least thirty five percent of the Uranium in the world is located in politically stable areas, like Canada and Australia.

Energy drives our daily lives. Most of the energy that is produced today is generated from fossil fuels. The demand for energy is increasing every day. There are two key reasons for that: first, the population of the earth is growing at an ever-increasing rate and second, societies worldwide are becoming more and more industrialized. While energy demand is growing, fossil fuel reserves are being depleted. In about 50 years we will have depleted most of our fossil fuel reserves, so it is necessary to find alternative sources of energy before that happens.

Fossils fuels were formed many millions of years ago. They are the remains of plants and other creatures that once lived. Pressure and heat applied to those remains over the period of millions of years produced the most essential sources of energy that we use today: coal, gas and oil.

Coal is used for producing electricity and heat. Coal is a combustible rock that releases energy when it is burned. Approximately 6.2 billion tons of coal is consumed each year. The largest portion – about 75 percent – is used for electricity production. The United States uses about 1.05 million tons of coal each year. China generates 68.7 percent of its electricity from coal energy. Natural gas is used for electricity production as well and it doesn’t produce as many harmful byproducts as other fossil fuels. The release of carbon dioxide (CO₂) is also considerably less when natural gas is used instead of coal or oil. The burning of natural gas produces 30 to 45 percent less CO₂ than coal and oil respectively.
