subjects in the world. Old power plants are struggling to keep up, sometimes causing power shortages or “brown outs”, and new power plants are being built, but most of the new plants still use the same technology as their predecessors. Some have even been ‘repackaged’ to appear cleaner in respect to exhaust, but they still pollute the atmosphere and use a dwindling source of fuel. Still others argue that fields of petroleum at deeper levels are more than sufficient to supply the world with oil1.

→ mitigate air pollution D. Cost-effective 1. Little nuclear fuel → much energy → effective 2. Lower unit price of nuclear power → economic III. Conclusion Benefits ( environmental friendly & cost-effective) ＞ concerns ( safety & waste disposal) → develop nuclear energy （1157 words） With the rapidly increasing population, human being’s demand for energy has become more urgent. Around the world, the finite fossil fuels are the main sources of energy. 85% of world energy are currently

(Guo, 2006) Nuclear energy has many advantages compared with other kinds of energy. For instance, nuclear energy does not cause air pollution unlike fossil fuels, which release polluting substances into the atmosphere. Because nuclear power does not produce carbon dioxide to aggravate the greenhouse effect, it is very helpful and necessary for the environment. The cost of nuclear power

resource issue is water pollution. There is an astonishing seventy percent of water covering the earth’s surface. That is a very substantial amount of water with an equal amount of water pollution opportunity. The definition of water pollution is the contamination of water bodies. Any variation of lakes, oceans, rivers, and groundwater are vulnerable to various bacteria and chemical compounds. There are many origins that water pollution can derive from. Man made pollution practice are the most

Environmental Protection Agency, 2014). Out of the 32 million tons of plastic waste that was created in 2012 only 9% was recycled (U.S. Environmental Protection Agency, 2014). Every year, about 100 billion tons of plastic are produced all over the world, less than 9% is recycled (REUSEIT, 2014). Plastic water bottles are lightweight, this makes them preferred over glass or aluminum bottles. Although, the weight difference may be only a couple of grams, it makes them easier to carry (PlasticsEurope

through energy system analysis of the current Danish energy system with 13-14% renewable energy, as well as possible future Danish energy systems with 43% (2025) and 100% renewable energy (2050), respectively. The technologies include combustion, thermal gasification, anaerobic digestion, fermentation, and transesterification technologies producing electricity, heat, or transport fuel. In the USA, according to the US energy recovery council, there are 87 WTE plants producing 2,700 megawatts that results

saline water potable and high temperature process heating. Solar energy in building is used by orientating the house relative to the sun, making it more compact, including patterns of selective shading and choosing building materials with certain thermal mass (heat capacity of a material). Every house should also be tailored to a certain climate it’s going to be located in. In agriculture solar energy is used to increase the productivity of plants. There are such methods of ensuring growth as timed

to most places around the world. Through this, it can create environmental problems such as soil contamination and pollution. Hazardous chemicals that get into the soil can harm plants when they take up the contamination through their roots. If humans eat plants and animals that have been in contact with such polluted soils, there can be a negative effect impact on their health. Now with the pollution, bad waste management practices can result to land and air pollution and can cause respiratory problems

Introduction: The population of the world continues to grow. Now, more than ever before, alternative energies have become an economic, social, and environmental necessity. The huge demand for energy, and especially Renewable Energy, around the world push us to seek new sources of energy. Generating renewable energy from the ocean through Ocean Thermal Energy Conversion, known as O.T.E.C. is one of the sources; it has been studied for nearly a century but, although several demonstration plants
