Fossil Fuels And Alternative Energy Sources Essay

Current wind energy installations power roughly twenty million homes in the United States per year and that number is growing.Unlike other forms of natural gas, hydrogen is a completely clean burning fuel.Once produced, hydrogen gas cells emit only water vapor and warm air when in use.The potential issues surrounding the use of fossil fuels, particularly in terms of climate change, were considered earlier than you may think.It was a Swedish scientist named Svante Arrhenius who was the first to state that the use of fossil fuel could contribute to global warming, way back in 1896.Most states in the nation now have some form of wind energy set-up and investment into the technology continues to grow.Unfortunately, this form of energy generation also presents challenges.These use the kinetic energy of the ocean to power turbines, without producing the waste of fossil fuels or being as susceptible to the elements as other forms of alternative energy. Burning wood has been used for thousands of years to create heat, but more recent advancements have also seen waste, such as that in landfills, and alcohol products used for similar purposes.Focusing on burning wood, the heat generated can be equivalent to that of a central heating system.The process of electrolysis, which is essential for the splitting of water into hydrogen and oxygen, makes this less of an issue.However, electrolysis still ranks below the previously mentioned methods for obtaining hydrogen, though research continues to make it more efficient and cost-effective.
