One of the toughest challenges facing humanity today is the finding and implementation of alternative electricity sources. The drive to find better ways to generate electricity has been around for over a century, but has faced opposition due to the inexpensive energy produced by coal and oil-fueled generators. Those natural resources are rapidly being depleted, and we can't put it off any longer- the need for more alternative energy sources is rising. In this article, you will learn more about these different sources of electricity, and how they can be used today.

The goal of finding alternative electricity sources picked up steam in the 1970s amid the global oil crisis. That crisis resulted in long lines at filling stations, and created shortages around the US. However, the search for alternate sources of energy is not limited to automobiles; homes and industries can also benefit. There have been numerous advances in the search for alternative energy, but the product still remains almost prohibitively expensive.

Sun, water and wind are much-touted and renewable sources of energy. Some claim that, once the technology is in place, these energy sources will become cost-efficient enough to replace the thirst for the natural gas and oil that fuels power-generating turbines. The research has gone so far as to include geothermal power production.

For a lot of people, using these alternative electricity sources is dependent on finding the type of power that is best produced in their geographical location. Those that live in areas where there is not as much sun exposure may not be able to fully benefit from solar panel installation. In other areas, wind is a plentiful resource that can turn the generators' turbines, but again, that's dependent on geography.

Another alternative electricity source is water; rivers power many hydropower plants, but the infrastructure necessary to get the power out from the generators is very costly. The three biggest alternate energy sources are seeing continual research and advancement, but the problem is evident every time someone fuels up their car or opens their utility bill.

Nothing is forever; the resources the planet was blessed with will eventually run out. The need for alternative electricity sources is great, and refining these sources will go a long way in solving the global energy crisis.
