This is done in a reasonable economic and environmentally friendly manner to face many global challenges related to the rising consumption of global resources. Alternative energy sources are not based on splitting of atoms or burning of fossil fuels.

This approach actually excludes otherwise atmospheric pollution from nuclear waste by-products and burning fossil fuels.

Hence, the alternatives that produce less significant impact on the environment include: Hydrogen fuel cells The well-developed economies like the US consider hydrogen as a source of great environmental potential since this clean energy fuel significantly reduces economic dependence on imported energy sources.

Therefore, the US deems hydrogen as the future alternative to gasoline; however the issue requires a lot of effort. Initially, the main issue on the agenda concerns facilities needed to make, store and move hydrogen.

Furthermore, economical fuel cells, appropriate technologies, innovative solutions and eco-oriented educational programs are the key prerequisites of the coming transformational process in the USA.

At present, the US produces more than 9 million metric tonnes of hydrogen, which is enough to power up to eight million households or 30 m.

However, for the time being, hydrogen is mostly applied for the industrial purposes, including metallurgy, refining, and food-processing. The overwhelming majority of overall amount of hydrogen production covers only three states: Louisiana, California, and Texas.

The primary user of hydrogen as an energy fuel is NASA within the framework of its space program. Specifically, fuel cells hydrogen batteries are applied to power electrical systems of the shuttle.

Hydrogen fuel cells are used as efficient means to make electricity. However, the construction of such large batteries which application excludes power lines is still expensive to build, whereas smaller fuel cells are actively applied to power electric cars.

Alternatively, fuel cells are also actively applied as emergency power sources in hospitals and remote locations.

In addition, portable fuel cells are available to power laptops, cell phones, and military devices. About vehicles automobiles and buses in the USA are hydrogen-fueled. Electric motors that use using a fuel cells store hydrogen gas and convert the hydrogen into electricity for the motor.

Such vehicles are deemed as exclusively eco-friendly since they do not pollute the surrounding environment. The issue high on the forthcoming agenda concerns the construction of re-fuelling stations available to power hydrogen cars Energy Information Administration, Ethanol Ethanol fuel is widely applied as a biofuel alternative to gasoline used in vehicles.

Ethanol is easily manufactured and processed made from ordinary crops, including corn and sugar cane. Further main advantage is that ethanol is a renewable resource and can be used immensely. Most US cars therefore apply gasoline-ethanol blends reducing the levels of hazardous emissions in the atmosphere Goettemoeller and Goettemoeller, Furthermore, bio-ethanol is manufactured mainly to replace fossil fuels in vehicles.

Concerns relate to the large amount of arable land required for crops, as well as the energy and pollution balance of the whole cycle of ethanol production.There are problems with oil, gas and coal, but their benefits for people—and the planet—are beyond dispute, writes Matt Ridley.

Essay on Fossil Fuels and Alternative Energy Sources; Essay on Fossil Fuels and Alternative Energy Sources. the world needs to replace fossil fuels with other sources of energy which are relatively low-cost and more secure. Renewable energy is such a potential energy.

About seven-in-ten (73%) of those ages 18 to 49 say developing alternative sources of energy should be the more important priority, while 22% say expanding production of fossil fuels should be the more important priority.

Energy Sources In the 21st Century. The major sources of energy in the United States are fossil fuels like oil, natural gas and coal which are used for generating electricity, driving cars and other vehicles, running industries, etc.
