    Alternative Forms of Generating Electrical Energy: Wind, Solar and Fuel Cell Power

    The societal demands for electrical energy have drastically increased in the past number of years. The sharp escalation of fuel consumption caused the demand for fossil fuels, which generate electrical energy, to increase as well. Almost 80% of domestic electricity use is used for space and water heating. To reduce the amount of energy produced by fossil fuels, the amount of electricity used must be lessened, and other renewable methods of electrical energy generation must

  • Fuel Cell Environmental Benefits

    Fuel Cell Environmental Benefits

    Fuel Cell Environmental Benefits High Fuel Efficiencies By converting fuel directly into energy through an electrochemical reaction, fuel cells extract more power out of the same quantity of fuel when compared to traditional combustion. This direct process results in a reduced amount of fuel being consumed and greater efficiencies, 30% to 90%, depending on the fuel cell system and if the surplus heat is utilized. Combustion-based energy generation first converts the fuel into heat, limited
