Fossil fuels supply nearly 90 percent of the energy, according to the U. Nuclear power accounts for roughly 5 percent; the rest is met by alternative or renewable energy. However, global consumption is expected to increase by 50 percent over the current rate by
Go Alternative Fuels Alternative fuels are derived from sources other than petroleum. Most are produced domestically, reducing our dependence on imported oil, and some are derived from renewable sources.
Often, they produce less pollution than gasoline or diesel. Ethanol is produced domestically from corn and other crops. It produces less greenhouse gas GHG emissions than gasoline or diesel. Electricity is produced domestically from a variety of sources such as coal, natural gas, nuclear power, and renewables.
Powering vehicles with electricity causes no tailpipe emissions, but generating electricity can produce pollutants and greenhouse gases.
Biodiesel is diesel derived from vegetable oils and animal fats. It usually produces less air pollutants than petroleum-based diesel. Natural gas is a fossil fuel that is plentiful in the U.
It produces less air pollutants and GHGs than gasoline. Propanealso called liquefied petroleum gas LPGis a domestically abundant fossil fuel. It produces less harmful air pollutants and GHGs than gasoline. Hydrogen can be produced domestically from fossil fuels such as coalnuclear power, or renewable resources, such as hydropower.
Fuel cell vehicles powered by pure hydrogen emit no harmful air pollutants.
With this designation, FHWA is facilitating the creation and expansion of a national network of alternative fueling and charging infrastructure along national highway system corridors. This is the next step in advancing America's 21st century transportation network.

Solar energy refers to energy obtained from the sun. It has the advantage of being % renewable and clean, but the disadvantage of being expensive and early in development. Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.
Renewable energy often provides energy in four important areas: electricity generation, air and water heating/cooling, transportation, and rural (off-grid) energy services.
1. Introduction. Rapid economic growth has contributed to today׳s ever increasing demand for energy. An obvious consequence of this is an increase in the use of fuels, particularly conventional fossil fuels (i.e.
coal, oil and natural gas) that have become key energy sources since the industrial revolution. Hydrogen, when used in a fuel cell to provide electricity, is an emissions-free alternative fuel produced from diverse energy sources.
Currently, drivers of fuel cell electric vehicles (FCEVs) can fuel up at retail stations in less than 5 minutes and obtain a driving range of more than miles.
