4th 21st Century Problem - Alternative Energy

Alternative energy is an energy source that is eco-friendly and renewable. Unlike fossil fuels (e.g Coal and petroleum), they do not produce carbon emissions such as carbon dioxide, methane and carbon monoxide. Examples of alternative energy sources include solar energy, wind energy, geothermal energy, biofuels, etc.

By using alternative energy, global warming can be greatly reduced. We can also reduce water usage as burning coal for energy requires a great amount of water. Coal mining can pollute nearby water sources whereas alternative energy does not or inflicts very little impact the environment.

Water pollution is reduced too as there would be much lesser oil spills. Petroleum is deadly to the marine ecosystem and can kill marine life easily. Also, if we consume fishes polluted with petroleum, it could cause cancer and other illnesses

Fossil fuels also produce a lot of toxic waste materials. Incomplete combustion of petroleum can create methanol, carbon monoxide and also fine particulates which can blacken human and animal lungs and cause heart problems or even death. These toxic materials are dangerous to both living organisms and the environment. Thus, we should consider alternative energy as a new means of obtaining power.
