Solar Energy

The Solar Energy as one of the alternative sources in life and which produced by the sun. Nowadays, air pollution is the biggest problem in our life and this energy is safer and cheaper.

There are some advantages of this energy. First, the price of this energy can’t be change in the future, unlike other prices for oil or gas. Secondly, solar power is a friend for the environment and it has zero pollution. Another useful thing is that it helps when the peak shaving reached highest during the use. There are two main ways to use the power of the sun to reduce energy costs in your home. You can use the heat from the sun's rays to heat your home or your domestic hot water, or to produce electricity to power lights and appliances. Sunset is a problem and storing the solar made the batteries prices more expensive. They found a way to keep power at night by adding cobalt and phosphates to water and pass through a solution a mild current with a glass electrode. The researchers advise that water must be and split to hydrogen and oxygen during night because hydrogen could burn or come out through the cell.

Photovoltaic cells (PV) are flat electronic devices which will convert the sun light immediately to electricity. Typical commercial photovoltaic cells convert 10-20% of the sunlight that falls on them to electricity. A separate report from industry analyst firm NanoMarkets forecasts that the thin-film PV market will produce the equivalent of 26 gig watts by 2015 and generate over $20 billion in revenue in that same time frame(Jusko).

In conclusion, solar energy is the future source for the earth and it can protect the environment for the next generation.

Road Safety

How to keep your self safe on the road? The safety on the roads has more than one part, and to keep yourself safe you need to follow some of the instructions that will help you to safe yours and others lives. There are a lot of studies shows that following the laws and the instructions on the roads and using the maintained vehicles will keep the people safe and prevent the accidents and death. Following the safety will save money and people. The studies show that in the entire world around 1,200,000 people die every year in car accidents. The Accidents are in 9th place in leading cause of death in the world. There are three parts of the road safety driving: road users, vehicle design and equipments and engineering measures.

First, knowledge of the road users must be good. For example millions of peoples die in poor countries because the knowledge of the drivers is poor and they haven’t trained well (WHO). The biggest cause of accidents is speeding above the road limit (Kumar).

Second, the vehicle must be designed to run on the roads safely. The fact in India shows that a small number of drivers uses safety measures or safety belts or even maintain they’re vehicle (Kumar).They have to use a check list of the equipments like Seatbelts, Adjusting mirrors, seat position, securing loose objects, not using cell phones while driving, checking the engine warning lights and checking the fuel status.

Third, engineering measures of the roads must be good for the users. The roads are built in a way that caused a lot of problems to the road users even because it is not well maintained or it is designed in wrong way. Beside these roads in India, they suffer from having less number of the traffic signals and high traffic density at the same time (Kumar).

In conclusion, the best thing to do is teaching the people about the rules of the safety driving on the roads which gives them the knowledge about how to protect their self. For example, in the United Arab Emirates, the person who applies for the driving license must learn in the driving technical institute about the rules and the vehicles.

Pollutions and Solution ????

Global warming appeared to the surface and has been detected by the experts and researchers. They found out that it is affecting the mother earth and caused big problems that will affect the nature around the people. The land area is affected and the water bodies too. On the water bodies the people are traveling on motorized boats and yachts between the lands. These motorized boats will affect the environment by using fuels and chemicals. Also throwing rubbish in the water and oil spills from the oil tankers can cause pollution. In this essay I will outline some main problems and solutions about marine pollution. Let’s discuss three ways that people make the ocean dirty.

One of the problems is that using the jet boats for skiing in the closed waters areas or lakes which will leave a film of unburned fuel and lubricants on the surface. For example, driving a motorboat for one hour makes pollution as much as driving 1300 Km by car (Rick). Another problem is the dumped waste in the rivers and oceans because of the growing population which will affect the animals and human being (Fadhley). For example, most of the dumped wastes are plastics which are not recyclable or bio-degradable. Third problem is the oil spills problem which has taken place in the oceans due to the ships oil spills and the industrial waste. For example, the oil spills is the main reason causing the animals becoming endangered (Meadows).

Although there are problems, also there are solutions for those problems. First, in the USA, the government phased tight emission standards for the motorboats to reduce the engines emissions like CO2, unburned fuels and lubricants (Sorum). To reduce dumped waste, another solution to control the waste is by the people them self by eliminating the use of the unnecessary disposal plastics. The oil spill is a major issue in marine pollution. One of its solutions is to use the booms all around the oil spills as a temporary solution (DAVIS).

In conclusion, the global warming is rising and it is affecting the nature around us. The marine life is facing the huge change of global warming affect. However, many other reasons are affecting the marine life nature as well. In point of view, the marine life is as important as the wild life. So eliminating the danger sources of marine pollution is highly needed. In addition to that, governments should act immediately to solve this issue.
