Global Energy Demand Essay

In terms of oil dependence, most of the general public believes that the world has enough oil to support us for the next hundred years; in truth we are rapidly depleting our petroleum sources due to the increasing population and demand. In fact, as was initially theorized by the Hubbert Peak Theory in 1950, Earth peaked in oil supplies in 1973 and the largest oil resources that have been discovered since then have been in Venezuela and Saudi Arabia. Here it must be

Petroleum has been a mainstay of the United State's economy for almost a century. However, oil has now been recognized as a strong catalyst for global warming, it is becoming scarce and therefore, an expensive necessity to America's economy. In the recent years many universities and scientists have looked for alternatives to oil in the form of renewable energies. These renewable energy sources would be cheaper in the long run, more efficient and environmentally clean. America as a whole must look into these new forms of renewable energy to determine if they are a practical alternative to the use of petroleum as an energy source. If we do not try to find a clean and efficient alternative to fossil fuels, I am concerned

Now we mostly use fossil fuels and natural gas to produce energy. But these sources are running out. To save our planet we should use a new class of renewable energy sources, like wind turbines, solar panels, biofuels and hydrogen. Because our need for power is constantly increasing in the future we will have to produce more energy, which is associated, among other things, with greater emissions of CO2 and further pollution of the environment and global warming. Most likely oil is going to be the first one that’s not going to be sufficient enough to satisfy our needs in the future. To transition to alternative sources of energy would require a rapid expansion of those sources. Now alternative sources of energy playing a small percent of the world’s energy. To transition we would have to triple or quadruple that percentage.

The main usages of petroleum are bunker fuel, detergent, jet fuel, diesel fuel, heating oil, paint, photographic film, food additives, make up, medicine, and candles etc. Actually, the petroleum usages are very broad. If the country is experiencing oil shortage, everything must be very expensive. You may eat some food with food additives, which is a material from petroleum, in your stomach, even though you do not drive or travel around the world by airplanes. Moreover, petroleum has a lot of advantages to generate electricity. It is easy to transport and store because it is a liquid. Compared with natural gas, natural gas is hard to extract and store because it is gas. Natural gas requires higher technology to extract and store it. Moreover, the density of petroleum is higher than natural gas and coal. We can save more room to store petroleum. For government’s aspect, they may want to use some energy, which are stable and easy to store. Although the renewable energy is unlimited and eco-friendly, the costs of built and operate it are expensive. So, the fossil fuels are the best energy for us to use now. Peak oil crises affect our life, and we cannot find any energy to replace it.

These sources of energy have a great upside, but right now are incredibly inefficient compared with fossil fuels because of the lack of funding and worldly push (2009). If there isn’t a bigger investment in these alternative energies, fossil fuels are going to maintain their stranglehold on all the economies of the world (Lomborg, 2009).

Whilst it may seem a “no-brainer” to cease investment in non-renewable power and transfer our effort, resources and investment into developing renewable energy sources, the reality is that we have become so reliant and dependent upon non-renewable energy – particularly fossil fuels – that we must continue to use, develop, and invest in such energy to maintain the living standards that we enjoy today. In our short to medium-term future, and in spite of our ever-increasing scientific knowledge about the environmental price that we pay in using non-renewable energy, we must continue to invest in it. Let me explain why.

For the past several decades we have been relying on oil as our major source of energy. It is oil that driven the industrial revolution and turn the global economy into what it is right now. However, the increasing rate of our reliance and hunger for oil has been causing us devastating problems so awful that we can’t afford to ignore it anymore. It is a fact that the global oil reserve won’t run dry in either today or tomorrow but we are running out of supply. I believe that oil should not be the only major source of energy because of the following reasons, first, the

The world right now is facing a major disaster if our habits don’t change. Fossil fuels dominate our energy demand and at our current rate this will remain true for quite some time. The World Energy outlook claims that by 2030 84% of our energy demands will be fulfilled by fossil fuels (Shafiee et al, 181). It is believed that we possess the reserves to meet our demands until 2030 (Shafiee et al, 181) but the cost will increase as time goes on. Fossil fuels are a non-renewable resource, meaning that once we run out of what’s currently available, we cannot replenish it. Our future energy needs are heavily dependent on a non-renewable and quickly depleting energy source.

Oil and gas have been the world’s commercial energy sources in recent century and it still remain this important role in the 21st century. As industrial productions have grown by approximately 50 times during the 20th century, this led to tremendous increasing of the energy consumption. Presently, oil and gas account for almost 40 per cent of the world energy sources because they are unique commodities and easy to transport in many areas with low costs. The advances of technologies make petroleum become cleaner, safer and more efficient energy. Consequently, oil and gas could meet more strictly environmental regulations and comply with the widely demands of sustainable development. However, petroleum is a scarce resource and the demands of energy consumption will be increased. Humans try to improve recovery rates by enhancing technology and developing infrastructure for better accessibility. Presently, the volatility and high prices of oil market have been a significant cause for concerning among many countries. Even the increasing price trend in recent year, the market has still remained

Modern society will remain dependent on crude oil, even with the development of alternative forms of energy. Oil consumption is vital because many heavy machineries, factories, ships, aircrafts, and automobiles are reliant on crude oil. It is true that efforts are being made (especially within the U.S.) to develop and employ other forms of energy, but, I think that sustainability of such efforts would be a major drawback.

Accounting for most of the world’s source of energy is fossil fuels. These sources are

Crude oil- plays an important role in the production of energy and united states consume more energy from petroleum than from any other sources. In 2014, 19 million barrels of petroleum was consumed by total U.S. i.e., 35% of all the energy consumed in the United States. Increase in population, industrialization and demand for energy, oil is diminishing at a faster rate each year. Therefore, it would cause a fossil fuel supply limitation with large economic impact, and the environment problems are both driving forces for actions towards a more sustainable energy system. In addition, scientists at the Energy Department’s National Labs are developing technologies to reduce

Today’s global engine runs on hydrocarbons such as coal, oil, and natural gases, with oil leading as the number one source of energy in the world. There are very few experts predicting a change in the model in the next twenty years. As scientists learn more about the environmental damage caused by hydrocarbons, they continue to search for alternative energy sources. Still, there is a rising middle class which in turn leads to more vehicles, more electric-powered appliances, and more coal-powered manufacturing plants. A lot of the northern

The most common acknowledged weakness of being dependent on oil/gas is the fact that these sources are going to deplete at some time. This phenomenon will be enforced by the increase in consumption over the next decades, as it is calculated that oil supplies would supply worlds demand for another 40 years and natural gas needs for 60 years.The need to be more self-reliant will only increase in western countries, as they will have to develop resources like solar and nuclear energy to substitute oil or gas (Stutz, 2007).

The world is depended on oil and soon oil will become more valuable than gold and could lead to a worldwide war. Price for oil could soar to above two hundred fifty dollars per barrel. Oil and other fuel cell also cause green house gases which contribute to global warming. China is consuming two times more petroleum than 1996 and India is projected to consume three times the oil it currently does by 2050. Global house gas emission has increased by twenty percent from 2003 to 2006. Energy consumption has increased exponentially throughout the globe. The U.S. department of energy projects energy consumption will increase seventy percent from 2003 to 2030. The world has agreed to reduce emission by twenty five percent before 2020 and by over
