A look at global efforts to find alternatives energy sources and vehicles that dont use oil

Alternative energy sources

Windmills may have even been developed in China before 1 AD, but the earliest written documentation comes from Therefore, it is essential to control the negative aspects on the one hand and develop the positive factors on the other. Once, these fossil fuels are all used up, they will no longer be a source of energy for the world to use. Robert W. The earth is filled with numerous renewable resources such as wind, nuclear, hydroelectric, and solar energy that can eventually solve the problem. Solar Power What better way is there to reach Type I status, than to get your energy straight from the source—solar power involves harnessing the power of our sun. It is more difficult to reduce CO2 emissions than it is to reduce reliance on diesel and gasoline consumption because the electricity used in hybrid EVs, PHEVs, and pure EVs PEVs in some regions is produced by using a high share of coal power [ 29 ]. Even if we only hold electricity demand flat, we can subtract a coal-fired megawatt every time we add a wind-powered megawatt. SG Biofuels , a San Diego-based Jatropha developer, has used molecular breeding and biotechnology to produce elite hybrid seeds of Jatropha that show significant yield improvements over first generation varieties.

Around twelve states have passed proposals written to inhibit the alternative energy movement. But in many ways PV is a much more elegant and sophisticated technology.

Application Obstacles Technology Technological immaturity and the high cost of new technologies are major obstacles for the widespread application of alternative and transitional energy sources in transportation.

They all have lower carbon emissions, compared to conventional energy sources. That goal appears attainable, and considerable progress is already evident. Although developing other alternative energy sources, including solar power, is also undoubtedly important, ever-increasing energy demands cannot be met unless we use atomic energy.

The most extensive deposits of all three are in North and South America. Linn Draper, Jr. With these statistics, it is no wonder people are coming up with alternative energy sources. Once, these fossil fuels are all used up, they will no longer be a source of energy for the world to use. Geothermal energy can be found anywhere on the earth.

Even if the United States switched its entire grain crop to ethanol, it would only replace one fifth of U. For biofuels, the high costs of production, transportation, and storage are some notable obstacles.

A case study conducted in Greece also proved that using biodiesel resulted in a substantial reduction of GHG emissions compared with using gasoline and diesel; however, biodiesel combustion increased the emissions of PM10, nitrous oxide, nitrogen oxides NOxas well as elements such as nitrogen and phosphorus [ 32 ].

List of alternative energy sources

Energy makes your cars move, powers electronic devices, and makes light bulbs give emit light. If the technical challenges in these two convincing technologies can be overcome, the energy costs of these systems could be an important component for placing an upper limit on oil prices. New discoveries, advanced technologies, and high-tech engineering may transform the energy landscape—and with it the shape of society. In addition, future improvements in battery pack energy density, operating temperature range, and life cycle are required to reduce costs and increase the driving range and battery life of EVs [ 13 ]. While these technologies are very promising, it still must be proven that large quantities of CO2 can be stored effectively underground and monitored for long periods of time. For electricity, the battery performance and recharging system are the main obstacles [ 21 , 22 , 23 ]. Mining coal disturbs the land and modifies the chemistry of rainwater runoff, which in turn affects stream and river water quality. Fossil fuels are a natural matter that is found in the ground of the Earth formed in a previous time period millions of years ago that are nonrenewable and are used for energy today. So the basic question remains: How long can we maintain our petroleum dependency? Indeed, whenever any fossil fuels are burned, carbon dioxide is released into the atmosphere, where it functions as a heat-trapping greenhouse gas. Production was managed by Dorothy Lewis. This paper will give information about each of sources as well as their advantages and disadvantages. There are no natural reservoirs of pure hydrogen; it must be extracted from compounds such as natural gas or water. One watt of power is equal to one ampere a measure of electric current moving at one volt a measure of electrical force. It is completely clean and renewable.
