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†¦show more content†¦Battery packs are still heavy, bulky and expensive but the costs of solar power are coming down while the cost of gasoline keeps going up. A number of different vehicles from sports cars to vans to golf carts have had solar panels added to flat surfaces, primarily their roofs. Some of the vehicles are ordinary cars which have been modified for solar; others are highly futuristic. The picture below is a good example of a futuristic design. The vehicle, called â€Å"car on a stick† was designed to be used as a streetlight when not being driven, which accounts for the one sitting at a higher elevation in the picture, as opposed to the one on the ground. It would also save on parking. Of course, this design is only an idea at this point, but it gives some interesting possibilities for vehicles (and cities) of the future.

In order for PVCs to become more practical, engineers will have to increase their efficiency. Current cells have an average efficiency of about 20% (Perch 2013). Ideally, the efficiency would need to be at least 30% to be sufficient to provide enough energy to keep the car running for a reasonableShow MoreRelatedEnergy Efficiency And Renewable Energy1975 Words   |  8 Pageswhile also distributing it more effectively. The most rational way to create and produce energy is to generate it renewably by utilizing naturally reoccurring resources. Perhaps, that is why energy efficiency and renewable energy are gaining more and more attention from the largest names in the financial, energy, and industrial communities. Government, manufacturers, and the consumer are all involved in the renovation of the energy system towards one that is cleaner and more proficient.

The use of technology requires the energy of fossil fuels to keep it running. By using fossil fuel energy we are releasing harmful green-house gases into our atmosphere, we are slowly bringing forth climate changes and environmental issues to our society. To respond to these global warming issues, we must promote awarenessRead MoreNutrient Pollution : Causes, Impacts And Solutions1889 Words   |  8 Pagesairborne sources enter the water in high concentrations. This process results in water that is too rich in nutrients. This in turn causes a chain of events t hat can cause widespread ecological damage to both aquatic ecosystems. In order to reduce nutrient pollution to sustainable levels and prevent a manmade ecological disaster, mankind must stem the flow of nutrients into our waterways by regulating the sources that contribute to it. To address the problem of eutrophication, the causes must firstRead MoreGlobal Economic And Environmental Sustainability1989 Words   |  8 PagesSince 1940, the world population has nearly tripled. With this nearly exponential growth in population came a major growth in economic and financial activity that is increasingly more global and complex (Ayres et al., 2013). To compensate for this growth in population and economic and financial activity, the use of natural resources has risen at a similar rate. Although continuous economic growth is the primary goal of an economy, the finite amount of resources constrained by the capabilities ofRead MoreThe Report On Climate Change Dictates5048 Words   |  21 Pagescarbon-constrained world with a carbon budget beyond which the irreversible catastrophic impacts of global warming may not be avoidable. To have a 50% chance of staying below 20C of global warming, 62% of fossil fuels proven reserves, and 88% of coal reserves must stay in the ground. Huge new fossil fuel developments, like the Galilee Basin in Australia, the tar sands in Canada and new resources in the Arctic, cannot be developed. Oil majors are caught in a dilemma; the challenge of choosing betweenRead MoreA Research Study On Global Warming5887 Words   |  24 Pageschoice but to divest their assets in the carbon-intensive oil industry and shift their interest to low-carbon energy portfolios, their corporate strategies will have to either gamble on maximizing short-term profits in oil production while facing increasing climate change risks, or adapt their strategies in response to such risks and gain the advantage of a head start in low-carbon economy.

As warm air collects precipitation forms, moist air is lighter than dry air; moist and dry air combined increase storm severity. Due to climate change, the air now collects more moisture than previously collected due to increasing temperatures. Australian Bureau Statistics (ABS) records steady atmospheric warming since 1950 at an average temperature increase of 0.9 °C, resulting in significant climate variations (2011). Increases provide additional heat and moisture, allowingRead MoreRenewable Energy : Solar Energy2471 Words   |  10 Pagesvigorously. The capture of the sun’s energy is underway but supplies only a small fraction of our current energy requirements. Non-renewable sources of energy have been the primary source of energy production throughout the industrialized world. Fossil fuel technology drives most of our economy. We power our cities, industries, and cars with petroleum based products such as gas and heating oil. In some areas there is still reliance from coal to generate power and heat.
