All over the world, oil is used as the number one fuel. We have heard so many times before, even from reliable sources, that petroleum will eventually dry up, such that men's reliance on oil had started to stagger. Different countries have started prospecting and drilling in new places, in their serious attempt to discover more black oil. The proponents of oil believe that the economy would be badly hurt because of the disposal of traditional fossil fuels. But it looks like on the onset, alternative fuels have actually become beneficial to our economy.

It is important to utilize the alternative sources of energy that are available to us in order to survive, and not be all the time dependent on oil as the only source of fuel. More so, the benefits of the alternative sources of energy that have become available far surpass the disadvantages. Fuels that are petroleum based have been proven to release harmful pollutants in the air and greenhouse gases, the latter of which were shown to accelerate global warming. This can be mitigated by using the available alternative sources of energy that have been proven to stop global warming, and help other people by making the air completely safe to breathe again.

Here are some of the major alternative sources of energy that are available today.

Solar power-it is the process that converts the sun's rays into energy. Most of the sunlight entering the Earth has not been absorbed, so it is just right to take the opportunity of using this unabsorbed energy. Solar energy is produced with the application of solar cells and several solar cells that are put together to form solar panels, thus converting sunlight into direct current energy through the photoelectric effect. As soon as light hits the cell's surface, electrons are released, and converted to usable electricity. Solar engineers are now trying to develop more effective solar cells that are efficient and effective, so that in future, we will be able to rely on the solar cells for the majority of our appliances.

Wind energy-it uses the power of the wind to generate electricity. Wind turbines are used to convert wind to electricity. These days, wind power supplies 1% of the electricity needs of the world, but with modern technology and the expansion of the industry, the percentage will rise significantly.

Hydroelectric power-it is the form of alternative energy that is used the most, about 19% of the world electricity. Electricity is generated by the falling water's potential energy, which powers a water turbine and generator. Hydroelectricity has proven to be quite effective. A lot of large dams have already been constructed for the exclusive purpose of creating this kind of energy.
