Nour Aljafari @55471 WRI 102‚ 11 am Nuclear energy: the future power supplier Ever since humanity has existed‚ there has been an increasing demand for energy as a means of survival‚ from its usage for cooking and warmth‚ all the way to electricity generation for production and agricultural activities. Today‚ over 80% of energy consumption comes from fossil fuels‚ which include coal‚ oil and natural gas (Irvine‚ 2011). However‚ those fuels are not renewable and won’t last for more than a

nonrenewable resources is fossil fuel. They are finite resources that will eventually dwindle‚ becoming too expensive or too environmentally damaging to retrieve. In contrast‚ renewable energy resources are constantly replenished and are important because of the benefits it provides for us as well as for the environment. Firstly‚ renewable energy technologies are clean sources of energy that have a much lower environmental impact than conventional energy technologies. Conventional energy technologies rely

Nuclear energy is needed according to the demands of the energy that creates electricity. Nuclear energy plays an important role in the air pollution because it reduces the carbon dioxide emitted to the air. According to the new research that was done by The Food and Agriculture Organization (FAO) of the United Nations (UN)‚ about the uses of nuclear technology‚ the radioisotopes and radiation used in food and agriculture to reduce these figures that was done 2014-2016 that shows 795 million people

PREPAID ENERGY METER The present system of energy billing is error prone and also time and labor consuming. Errors get introduced at every stage of energy billing like errors with electro-mechanical meters‚ human errors while noting down the meter reading‚ and errors while processing the paid bills and the due bills. There are many cases where the bill is paid and then is shown as a due amount in the next bill. There is no proper way to know the consumer’s maximum demand‚ usage details‚ losses

Introduction Several years ago energy drinks barley existed. Not all people were familiar of it. People who consumed it did not understand the bad health effects behind it. This is because they were not as popular as it is today. Nowadays‚ energy beverages markets grew rapidly in recent years. There are many different brands of this drink in the world today. These beverages have caused many health problems to those who consume them. One group affected by the high consumption of energy drinks are children.

ASTOUNDING SOLAR ENERGY FACTS What is solar energy? People often think of solar energy as solar panels mounted on roofs in sunny neighborhoods. This is only part of solar energy (“Solar energy facts‚”2012). Solar energy is the oldest energy source. Plants‚ animal and the microbial life have been using it as a principle energy source since the times of creation. It is in the form of heat and light. In the past years‚ people have tapped solar energy enabling it to be used at all times; including
