A triple understanding would emphasize the importance of alternative energy resources in the near future.
- The reasons why the mindset towards the use of alternative energy resources will change over the next half century.
- How this change (i.e. the use of alternative energy) will affect automotive technology.
- The various types of alternative energy resources that are available, or currently under investigation, especially for use in automobiles.
The advantage of alternative energies is the fact that they are renewable. We will never run out of renewable energy supply. For instance, solar energy – the sun will always be there! – the amount of solar electricity intercepted by the Earth every 60 seconds is greater than the amount of energy that the entire human race uses in fossil fuels each year.
Wind power – the wind will always exist – The power of the winds blowing across the US produces more than 16 billion GJ of electricity annually. Tidal energy – The moon will always be here and so will its forces that cause tidal waves. Hydroelectric power – Water energy will always be available unless there is an extreme change in rain or drought patterns. Another advantage is that renewable energy is green; therefore, they do not exude CO2, which is in fact the largest provider of global temperature increases, into the atmosphere.
Biofuels are carbon neutral, since their manufacture uses up as much CO2 as it causes them to be spent. Taking into account these advantages of renewable energy, it is suitable to produce simple and inexpensive energy resources. Non-renewable resources (eg carbon-based fuels) are restricted; your supplies will eventually run out in the long run. Non-renewable resources like oil release CO2 into the surrounding atmosphere. These are inadequate sources of fuel that are rapidly weakening as the energy crisis continually hits us. Therefore, we can firmly agree that alternative resources are the future and will provide a better future.
What is the “car of the future”? A car of the future is a vehicle that runs on alternative fuels. “Alternative fuels” are fuels that are not made from petroleum. The types of alternative energy resources:
o Alcohols: ethanol and methanol.
o Compressed natural gas (CNG)
o Electricity: stored in batteries.
o Liquefied natural gas (LNG)
o Liquefied petroleum gas (LPG)
o Liquids made from coal: gasoline and diesel fuel that does not come from petroleum.
o Biodiesel – very similar to diesel fuel, but made from vegetable oil or animal fat.
According to experts, hydrogen powered cars it will be the next BIG change in our mode of transportation. In theory, it can be drawn from a wide variety of sources. The most common sources are water; Natural gas (methane); Coal (by gasification of coal); and Biomass (vegetation such as wood chips and agricultural waste). To get hydrogen gas out of water, electrolysis is used, that is, electricity is used to extract hydrogen molecules from water. Starting with natural gas, a “reforming” process is used. For fossil fuels or biomass, the substrates are the fuels of power plants, which use them to generate electricity and hydrogen.
The meaning is simple and clear: we need an uncontaminated renewable electricity generation technology. For now, the problem at hand is discovering alternative energy solutions to power our vehicles. The mission is huge, but it is certainly achievable.
