With the increasing costs, both financial and ecological, of fossil fuels, fuel efficiency in vehicles has become an increasingly important factor. Vehicle manufacturers and designers are exploring alternative fuels, with electric, hybrid and hydrogen-powered vehicles being looked at as viable alternatives. Solar power has been somewhat overlooked but has the ability to become widely used because it is both clean and economical. The advantages over fossil fuels are obvious: Solar power is renewable, cannot be exhausted and doesn’t cause pollution. Fossil fuels are becoming increasingly scarce and expensive. Solar seems like a logical alternative. As such, it is being considered by private companies and government think tanks as a partial solution to the dependence on fossil fuels. The question is whether the technology is robust enough to act as a complete fuel source.
What is a Solar Vehicle?
Traditionally, solar-powered cars were intended to be directly powered by energy from the sun. The potential in this technology got its first recognition based on a series of annual races across Australia (What 2013). At the moment, there are no true solar cars on the market although that is expected to change, perhaps as early as 2016 (Perch 2013). However, the definition of solar is changing as the technology matures. Solar power now also refers to cars which can be recharged from solar panels at one’s home or business, known as plug-in electric vehicles (PEVs). Plug in stations which attach to the public grid are starting to be available on the street and at local malls, providing an alternative way to recharge the vehicle if solar runs low. Solar/electric powered cars are believed to be the wave of the future as they will significantly ...

The sun has been a major aspect of life since the beginning of time. People used many other forms of energy before electricity was discovered. There has been a debate over energy resources for years. Many people are worried about what current energy resources may be doing to the environment. Oil spills and nuclear power plant mishaps have only been a few accidents that have had a big impact on the environment and the people who inhabit it. There are plenty of energy sources that do not harm the environment and are still able to get the job done. Solar energy is one energy alternative that will insure the betterment of the country and, at the same time, protect the natural environment.
In the future the global car market is full of potential. There are currently 44 million vehicles and by the year 2002 experts estimate that number will grow to 64 million. That growth is not expected to be in the US, rather in countries such as: China, India, The Pacific Rim, South Africa, and South America. In America, a current trend is for the neighborhood car dealer to be purchased by a large manufacturer, such as GM, so cars can be sold through retail outlets. Other future endeavors include low emission cars, which are expected to provide expansions in sales. Some major automakers are investing in fuel cells, devices that convert liquid hydrogen into elec...
...t of the electric car for the economic and practical benefits that would reinvigorate the country and make life easier for everyone. Upon revisiting the original question to this essay, the electric car is a worthy solution to our energy crisis and proves to be an economically responsible car. Its long-term cost savings outweighs easily improved flaws. However, in order to better understand the work done by scientists, research must be done specifically on the predecessors to the electric car and determine how those have stood the test of time. This will be done in order to help predict how the electric car will survive in the world. The future may always have a hint of uncertainty, but if scientists, governments, and drivers implement the new car with care, the goal of a smooth transition from fossil fuels to renewable energy sources can finally be achieved.
Energy is the basic necessity of daily life. Nowadays, dependence on fossil fuels for energy needs becoming lower in numerous countries due to the potential of renewable energy to supply sustainable energy to the huge populations in many developing countries who are short of clean and continues energy. Generally, renewable energy can be defined as energy that is derived from natural resources which are constantly replenished and theoretically inexhaustible. Fossil fuels on the other hand can be described as energy that cannot be renewed and will eventually diminish. Thus, in many developing countries renewable energy is the alternative energy to replace non-renewable energy or commonly known as fossil fuels. In addition, according to Sorensen (2004), there is a greater demand for renewable energy sources nowadays due to the uncertainty of fuel price rise in living expenses. Commonly, there are many types of renewable energy available in our world such as wind power, biomass energy, solar energy, hydroelectric power and geothermal energy. However, the main three example of renewable energy are hydroelectric power, solar and biomass energy (Refer to Figure 1 in Appendix 1).

... and monthly water filling. Solar energy is the cleanest and purest form of energy, allowing for cleaner air overall in our environment. There is great hope for a lot more solar panels to be installed worldwide. Solar is a viable alternative energy with solar panels becoming more affordable and more efficiently designed.
In this case study I will be discussing advantages and disadvantages of electric cars. Electric cars are cars that are powered by electricity. Electric vehicles are an important part of cutting emissions and reducing global warming. The battery of an electric car stores electrical energy. The electric motor is coupled to the wheels through gears; it converts 59-60% of electrical energy into the wheels. The battery runs the motor which allows the car to move. Electric cars are necessary as they will save money, because electricity is cheaper than gas. Also electric vehicles will help reduce global warming and pollution. However, some people say that electric cars still have environmental costs. The electricity used to recharge EV batteries has to come from somewhere in the world, and now, most electricity is generated by burning fossil fuels. Although electric vehicles are classified as green cars, purists will not appreciate the toxicity of the batteries.

Most people today fill up their car with different qualities of petrol, because that's what the average car takes. They don't usually consider an alternative for the petrol that they load into their cars. Although petrol is widely used, it is not the only source for a car to get its power from; diesel and electricity are alternatives to the general petrol used by most cars. Although different from each other, diesel and electricity are alternatives to the average gasoline received at a gas station. Diesel is a more concentrated type of fuel that is usually used by big automobiles because they require a lot of power in a little amount of time. Electricity is a method that uses the power of batteries to produce a low horsepower but, nevertheless fast automobile. Electric cars are generally created to be soundless and environment friendly. The purpose of this paper is to classify and educate the reader of the different types of fuel available for an automobile to use: petrol, diesel, and electricity. The general petrol, used by most people, is usually the only type of fuel accepted on the average car in the United States today.
I am certain that all have heard of the terms greenhouse gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today? What if I answer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008).
The Earth captures around 342 W/m2 of energy from the sun. This energy is in the form of solar radiation, which the atmosphere reflects about 77 W/m2 and will absorb around 68 W/m2 of solar radiation annually. Therefore, the Earth’s surface is receiving, on average, about 197 W/m2 of solar radiation annually. This amount of energy received is roughly more than 10,000 times the amount of all energy humans consume per year. This energy can be used to produce electricity or heat. This energy source is not being used to it’s potential considering how much effort would come into effect to store and transport this energy.
