Hydrogen power is a little harder to understand than other power sources that one is used to experiencing every day such as the sun and wind. Hydrogen power results from the reaction of hygrogen gas and oxygen gas to create water (Karim and Strickland, 2000). This reaction creates a lot of energy that can be harnessed by fuel cells and used to produce electricity.
There are several advantages to hydrogen power. For one, it is a very clean source of energy. It releases very few harmful emissions unlike burning of fossil fuel for energy, which creates harmful greenhouse gases. Use of hydrogen power decreases the United States' reliance on foreign oil. Hydrogen power can be used to power vehicles. Also, it is not reliant on weather conditions and can be produced anywhere in the world. Some of the disadvantages of hydrogen power include cost, safety hazards and small fuel cell size. It is expensive to produce, store and transport hydrogen fuel. This is partly related to safety hazards related to hydrogen gas. Hydrogen gas is highly explosive. This was disastrously demonstrated by the Hindenburg, an airship kept afloat by hydrogen gas, which is lighter than air, which exploded into flames in midair and crashed. Another drawback is the small size of fuel cells that can be used to power vehicles. Because they have such small fuel cells they have a limited range before refueling is necessary.
Each alternative energy source has its own set of advantages and disadvantages but in comparison to the major disadvantage of continuing to consume fossil fuels at an alarming rate each is well worth considering. One of the major drawbacks to alternative energy sources in general is cost, especially initial cost. This can be overcome by technology. As technology...
We want people to come into the Lagos economy. There is room to do this by: obtaining a resident registration card. The value of registration will benefit everyone in terms of: the provisions of amenities, security and the protection of businesses. This is an enormous step forward." (Fashola Signs Lagos Residents' Registration Bill into Law 2011) The information from this source is useful because it is illustrating how the state
Siemens' Case Study The time is now. Fossil fuels are quickly becoming an outdated energy source, because they are rapidly depleting. For energy companies like Siemens, it is now the crucial moment where there needs to be adjustments in strategy to reflect a changing world. However, the company must be in a good financial position to do so. Clearly, there needs to be enough free cash to reinvest into alternative energy
Homeowners and small farmers in windy, flat areas are already using the wind as a source of power. However, the use of wind energy is problematic: the wind provides an intermittent source of energy, and once captured, it must be rationed carefully. Solar energy Power plants and homes with solar power systems or solar panels can use the sun as a heat source or source of renewable energy. However, solar power,
alternatives to traditional fossil fuels, and evaluate them based on their relative availability, renewability, and known environmental impacts. We begin with a baseline characterization of fossil fuels, and outline some of the factors contributing to their current market and industry dominance. We then examine three of the current most prominent and viable renewable alternatives to fossil fuels, including the controversial nuclear energy technology and two emerging technology areas, wind
Technology Energy Efficiency The idea of electric cars, which run on big rechargeable batteries in opposition gas-powered internal combustion engines, has been around for years. But growing climate-alteration worries, tougher fuel-efficiency standards, billions in government subsidies, and a lot of venture capital seem to be generating a tilting point that could move electric cars from the transportation borders into the majority (The future of the electric car, 2010). An electric car by definition
Tidal energy could be another option, which has limited access. This means that energy plans should include a combination of all alternative types of energy that can be used in a certain region. All things considered, energy conservation is an issue that raises many concerns on global level, institutional level, and individual level. At global level, it is the world's states' responsibility to agree upon general directions that need to
