Nuclear energy should not be a resource after what happened in Japan on 11 march 2011. That day a Nuclear power plantation has been destroyed by an earthquake in Japan. It causes radiation all around Japan and many people died. It doesn't matter if the disaster happened on Japan just because Japan is known for tsunami, earthquake, storm surge, and floods.This global warming situation is out of control for everybody so this can happen anywhere and if any natural causes hit any nuclear power plant…

Different families with different professions came out to the West for a better life in 1845. They faced struggles particularly in adapting to their new life, but they managed to get by and start a new life. Some adaptations made by the newly Westerners were shelter, professions, and lastly the danger and risks that come along with moving to the West. In particular Ranchers they were a group of people new to the west. The dangers and hardships to be overcame and adjusted to in that profession…

Two main environmental concerns associated with the use of coal are pollution, caused by emissions of contaminants such as sulphur dioxide, nitrogen oxides and mercury, which affects human and environmental health, and greenhouse gases that are emissions that contribute to global warming. Social problems include the social and health complications that arise from the effects of the use of coal and coal mining. The mining of coal occurs in many ways, but is almost always damaging to the…

In essence, Tesla coils are a high-voltage, resonant transformer circuits. They consist of the six major components (Behrend 1), namely: Primary transformer Tank capacitor Spark gap Primary coil Secondary coil Toroid Figure 1: Tesla coil (diagram) A primary transformer is a step-up transformer that takes the line voltage of the AC source and steps it up to a range between 12 kV and 50 kV at 60 Hz (Johnson 4). The efficiency of this transformer is largely dependable on the construction…

called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity. Some of the pros that are related to nuclear energy, is how little it releases greenhouse gases (CO2) because it does not burn oil or coal but instead use uranium are its main power supply. Another benefit that is unique to nuclear energy is the fact that nature…

invented the light bulb in 1880”. Ever since then humans have been inventing and finding new ways to make life easier for themselves. The one thing that all these ideas have in common is the use of electricity. The main sores of electricity are coal and oil. Coal and oil is an ideal power sores, but the only problem is it is not renewable and one day will run out, as well as it leaves a carbon food print. One of the problems is the smock that is made, it can cores people to couch and can give…

his opinion, we have to utilize nuclear energy source more than the other energy sources for environment. He believes that nuclear energy is a clean, safe and dependable energy source. Nuclear power should be deployed rapidly to take the place of coal, oil and gas in the industrial places. I partly agree with the writer. I strongly believe that nuclear energy is neccessary energy source because the developing world needs more energy. Beside the nuclear energy, we also may…

In the ancient times people used simple tools to operate and secure their lives, but as the world evolved they have invented improved tools to insure longer and better life. Some of these tools are electricity, water pipe systems and others concern critical issues, such as health and nuclear energy. Inventions such as the defibrillator, heart-lung machines and even robotics, as well as nuclear reactors are also known as safety-critical systems. They are increasingly computer-based systems, but…

required time to payback the embodied energy of the product. It is evaluated as [142]: (6.1) 6.3.3 CO2 Emission Watt et al., have reported that, the emission of average CO2 is approximately equivalent of 0.98 kg of CO2/kWh in the electricity generated by coal [143]. The CO2 emission per year can be calculated as [144] (6.2) 6.3.4 Carbon Mitigation and Earned Carbon Credit The mitigation of carbon dioxide (CO2) is used to measure the climate change potential. The net CO2 mitigations are…

Discussion There are obviously both negatives and positive impacts of Mpumalanga coal mines. Positives being the economic growth they provide not only to Mpumalanga, but to South Africa as a whole. While negatives being the environmental damages they have caused and are causing presently. Mostly on the agriculture due to the land destruction and the polluting of water and air which is having a knock on effect of the communities living in Mpumalanga. In order to find out whether the positives…
