Can Nuclear Energy Be the Answer? It is only possible to mitigate global warming if the world-wide consumption of fossil fuels can be drastically reduced in the next 10 to 15 years. There is simply no room for a scenario as it is depicted by Lester R. Brown in the book Plan B 4.0 Mobilizing to Save Civilization. The scenario plays out like a horror movie‚ poverty‚ depleted water supply‚ food shortages‚ terrorism‚ over population‚ disastrous floods‚ erratic changes in ocean currents and global

Nuclear Energy 1. What is nuclear energy? Text Book Pg 80 2. Nuclear Fission :- In nuclear physics and nuclear chemistry‚ nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei)‚ often producing free neutrons and photons (in the form of gamma rays)‚ and releasing a tremendous amount of energy. The two nuclei produced are most often of comparable size‚ typically with a mass ratio around 3:2 for common fissile isotopes.[1][2].The smallest

Coal is an un-renewable fossil fuel which is known as a cheap and reliable energy source. It has many environmental impacts‚ both positive and negative. Coal has a great economical effect providing thousands of people with jobs‚ and harmfully leaving individuals with un-producible land. It has a social impact negatively when people live near coal mines. Coal is a flammable‚ mostly black rock‚ which has been located in 50 different countries around the world. Coal is known as a fossil fuel because

Effects of Pollution 1. Environment Degradation : Environment is the first casualty for increase in pollution weather in air or water. The increase in the amount of CO2 in the atmosphere leads to smog which can restrict sunlight from reaching the earth. Thus‚ preventing plants in the process of photosynthesis. Gases like Sulfur dioxide and nitrogen oxide can cause acid rain. Water pollution in terms of Oil spill may lead to death of several wildlife species. 2. Human Health : The decrease in quality

Solar Energy Solar energy in one form or another is the source of nearly all energy on the earth. Humans‚ like all other animals and plants‚ rely on the sun for warmth and food. However‚ people also harness the sun’s energy in many other different ways. For example‚ fossil fuels‚ plant matter from a past geological age‚ is used for transportation and electricity generation and is essentially just stored solar energy from millions of years ago. Similarly‚ biomass converts the sun’s energy into a

are two primary methods for generating electricity from water. One method uses the energy potential of trapped water in dams in a more sophisticated version of the water wheel‚ and the other method of generating electricity is to capture energy from ocean waves. Electricity generated from water is entirely renewable‚ sinccete water is an abundant natural resource First method:When a dam is used to generate energy‚ tunnels are installed in the dam when it is built. These tunnels are lined with turbines

Panels- They make electricity so you don’t have to buy it. You don’t have to use coal/oil/something else to create electricity‚ so it saves fossil fuels also. Tankless Hot Water Heater- Heating water is the 2nd highest energy use in the home. This device saves energy by eliminating the storage tank for hot water that has to be constantly heated. You only heat the water you use. Florescent Light Bulbs- These use less electricity than an incandescent bulb for the same amount of light.
