Alternative fuels: a must in our current situation

Global warming has been a big topic for a while now, and with the vast amount of vehicles on the road, it is becoming a more serious topic. According to NASA, Earth’s CO2 levels are at the highest they’ve been in the past 650,000 years. CO2 is an essential element to sustain life here on earth. The light from the sun passes through the atmosphere and is absorbed into the earth, it then is radiated back up in the form of infrared heat. Most of the light is absorbed by CO2 and other greenhouse gasses and is then radiated back to the surface to warm earth to a life sustaining temperature. We basically live in a greenhouse.

There is only one problem, us. Since the industrial revolution CO2 levels have risen significantly. This is due to the immense amount of machines operating off of fossil fuels and producing CO2. According the NASA, “The industrial activities that our modern civilization depends upon have raised atmospheric carbon dioxide levels from 280 parts per million to 379 parts per million in the last 150 years. The panel also concluded there’s a better than 90 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in Earth’s temperatures over the past 50 years.”

The increase in temperatures can cause abstract weather, changes in the ocean currents, and other serious problems. In order to fix this issue we need to find an alternative fuel that can replace gasoline and still provide the same performance. Some methods have been experimented with. Methods like electric cars by battery, or ethanol. These methods are not solutions because they still cause harm to the planet in different ways. What we need is a fuel that is efficient and healthy for the environment. Some alternatives that have recently been released look promising, such as solar power, hydrogen, and natural gas. Hopefully in the future we will be able find an alternative and help stop the damage that burning fossil fuels has done.
