Alternative Energy Sources
In the world today, alternative energy sources are becoming more and more of a necessity. Right now, the world’s energy demand is greatly increasing mostly because of population growth. Even though the rate of population growth is very diverse in different countries, the world’s population doubles about every thirty years. The world energy use is doubling every fourteen years (Hodgson). Still, the main energy source is oil. The other primary source of energy is coal and there is still plenty of it. The only problem is that coal is even more polluting than oil, which can lead to climate change and acid rain. These are the reasons why the world is in an energy crisis right now. This world needs clean energy sources to meet the population’s energy needs as soon as possible.
This combination of an increasing need for energy and a decreasing supply of oil and coal shows that alternative energy sources can be what will help to stop the world’s energy crisis. There are many different types of renewable energy sources and they all work in different ways. Most alternative energy sources give off little to no pollution and help reduce global warming. Also, renewables end up paying for themselves in as little as five years. A few popular alternative energy sources are wind power, solar power, hydropower, and biomass power. The use of alternative energy sources should be increased because they decrease global warming, do not give off pollution, are renewable and cost-effective.
Since oil and coal are not renewable resources and the environment that we live in is highly polluted, there are some questions that bring up many arguments. Questions such as: Should the use of alternative energy sources be increased dramatically or not at all? Or are these alternative energy sources really going to help save the environment? And will these alternative energy sources be the solution to...
