Worlds demand for fossil fuels
Social and economic development has brought an age of high energy consumption and demand. Over the last two hundred years energy consumption in the four economic sectors (residential & commercial, industrial, transportation and electric power) has increased globally and in the next two decades global energy use will rise significantly. Our energy use however depends in large part on fossil fuels, Despite the fact they are cause of serious environmental impact (contributing to green house gasses causing global warming), can be source of political tensions, and they are finite sources of energy. For this reasons there is investment in alternative sources of energy and renewable energy. These forms of energy include:
• Nuclear
• Large hydro
• Wind
• Solar thermal
• Solar photovoltaic
Nuclear energy is derived from uranium a radioactive metal which is mined in different parts around the world. Nuclear fission is the splitting of unstable atoms. For example if an atom of uranium is hot by a neutron it will split in two other atoms and two neutrons and releasing energy. If the process is repeated often enough it can release large amount of heat. This process occurs naturally, giving off radiation, but when it is sped up by enriching natural uranium to contain a higher proportion of U-235, in the right conditions it can become a self-sustaining chain reaction that releases immense amounts of thermal energy. The heat generated from this process is used to heat up water in the reactor, the water becomes steam, it moves turbines driving a generator and making electrical energy.
Nuclear energy is not a limitless source of energy. Current conventional thermal nuclear reactors around the world in total consume about 70.000 tons of uranium per year. Uranium is widely distributed around the world and in total we have about 3851 million tons. Which can amount for 55 years of supply, and if we consider hypothetical reserves the lifespan of uranium becomes 200 year. This doesn’t differ much from the fossil fuels: In total lifespan coal is expected 200 to 400 years for example. There are plans to develop recycling nuclear reactors: breeder reactors and depending on the rate of nuclear energy use we could need them by 2050. What breeder reactors do is improve the efficiency of the reactors, which currently stand at 2% to 75 or more and this could significantly raise the lifespan of uranium to eighty thousands of years.
Breeder plants development however present several problems: associated in creating a uranium cycle joined with a recycling cycle (including the costs involved. Demonstrations of breeder plants were constructed in France and Japan. These have proven to be very expensive compared to normal reactors- and they are due to be shutdown. The very few breeder reactors that work at present produce less energy that the closed breeder reactor projects.
An alternative solution to the problem of the life span of nuclear...

Is Biodiesel a Viable Alternative To Diesel From Fossil Fuels For Trucks And Buses?

1029 words - 4 pages of sulfur compounds and aromatics (Habmigren, 2003). Until today, it is still the only alternative fuel for motor vehicle. The biodiesel blends have ranged from 2/98% (B2), 20/80% (B20), to 100% (B100) (Hafman, 2003). The reasons biodiesel is a viable alternative to diesel from fossil fuels for trucks and buses are it can reduce the pollution, it can enhance the country's economy, and it is renewable sources and can produce almost same energy as

Road To Sustainability Essay

1175 words - 5 pages to the U.S. Energy Information Administration, fossil fuels meet around 82% of U.S. energy demand. And the other 18% of the demand is made up of all types of renewable energy sources. There are countless types of renewable energy sources, but these industries still have not taken off to achieve the goal of the global change of transitioning from fossil fuels to renewable energy sources. Renewable energy has become one of the main pillars of

Biofuels

1222 words - 5 pages the wide-ranging consumption of fossil fuels, researches argue that agricultural based fuel or bio-fuel is one alternative to replace fossil fuels and apply it as a new energy source. In general, bio-fuels are fuels that predominantly are produced from bio-renewable or renewable feedstock, such as corn, sugarcane, wheat and so on. There are many kinds of bio-fuels and each country develops different types. For instance, Brazil produces sugarcane

Fossil Fuels

1042 words - 5 pages power nearly everything. The fossil fuels were used to power trains to compensate for a lack of firewood and charcoal. This was also the time when automobiles had to become more affordable to the public, so the demand for fuel continued to rise. As time went on, fossil fuel demands sky-rocketed leading to more excavation for coal and oil deposits. The usage of fossil fuels has led to world that we live in now, but due to our overpowering

New Energy for the Future

The industrial revolution relied on coal for the new inventions brought into the world. Life as has never been the same since then. However since that time, there has been little done to improve on energy efficiency and humans still primarily rely on fossil fuels for energy. For over a hundred years the Earth has become more polluted and dirtier than

Fossil Fuels vs. Renewable Energy

Currently, humanity and even the planet itself has been taken hostage by the humanity’s stubborn attachments to fossil fuels, which has caused the world’s governments give very little attention towards the development of renewable energy. Fossil fuels are directly related to many environmental hazards. Kenton

The complexity and scale of these interactions are now increasing, especially as resources became more scarce and competition for them increases. In particular, fossil fuels are the natural resources in question. Fossil fuels, which include oil, coal, and natural gas, are primarily used for fuel purposes. These natural resources are given the name fossil fuels because of how they are produced
