Energy Source Definition (according to Merriam Webster): usable power that comes from a particular source for example heat, oil, radiation, water etc.
Ever since the Industrial Revolution we have become accustomed to oil as our primary source of energy. But because we were dependant solely on oil for decades, the time has come where Oil is close to its depletion. Knowing this, mostly during the 21st century, governments and scientists together have searched for efficient alternative energy sources to keep the energy circulation within nations up and running. Fortunately many sources have been discovered and is being tested in several countries such as Iceland running on geothermal (Thanks to the nearby volcanoes) and hydropower (Island) in which supplies 100% renewable energy. However there are several hurdles to this process of transferring energy sources. Firstly not all nations are as geographically opportune as Iceland. Secondly it costs the government and private industries millions of dollars. Thirdly the discovered energy sources are not as efficient as the constantly running oil flow. Fourth and hopefully final issue is that as of now these alternative energy sources are not entirely environmentally friendly as it requires vast spaces of geographical bodies also on the same note nobody can predict the futures weather fluctuations due to the rise of global warming. On a happier note, everyone is still in the process of finding solutions to these problems and trying to create a natural and smooth transition between energy sources for the best prospect of the future.
International Forum on Globalization with content provided by the Post Carbon Institute states that "conventional energy sources such as oil, gas, coal and nuclear, are either at or nearing the limits of their ability to grow annual supply, and will dwindle as the decades proceed but, in any case, they are unacceptably hazardous to the environment." Hence the report suggests that there are 6 promising alternative energy sources that we can rely in the coming future. Listed in no particular order. (Source Description by Listverse)

- Wind Power
- Wind power is the conversion of wind energy by wind turbines into a useful form, such as electricity or mechanical energy. Large-scale wind farms are typically connect to the local power transmission network with small turbines used to provide electricity to isolated areas. Residential units are entering production and are capable of powering large appliances to entire housees depending on the size. Wind farms installed on agricultural land or grazing areas, have on the the lowest environmental impacts of all energy sources.
- Solar PV
- Photovoltaic Solar power is harnessing the suns energy to produce electricity. One of the fastest growing energy sources, new technologies are developing at a rapid pace. Solar cells are becoming more efficient, transportable and even flexible, allowing for easy installation.
- Hydro (63%)
- The source of the production of power through the use of gravitational force of falling or flowing water. It is the most widely used form of renewable energy. Small scale hydro power has been an increasingly popular alternative energy source, especially in remote areas where other power sources are not viable.
- Geothermal
- Geothermal energy is a very powerful and efficient way to extract a renewable energy from the earth through natural processes. This can be performed on a large scale for energy production through a geothermal power plant. It has been used for space heating and bathing since ancient roman times, but is now better known for generating electricity. Geothermal power is cost-effective, reliable and environmentally friendly, but has previously been geographically limited to areas near tectonic plate boundaries.
- Wave
- Wave power is the transport of energy by ocean surface waves, and the capture of that energy to do useful work. Wave energy can be difficult to harness due to the unpredicability of the ocean and wave direction. Wave farms have been created and are in use in Europe, using floating Pelamis Wave Energy converters. Most wave power systems include the use of a floating buoyed device and generate energy through a snake motion, or by mechanical movement from the waves peaks and troughs.
- Tidal
- Tidal energy can be generated in two ways, tidal steam generators or by barrage generation. The power created though tidal generators is generally more environmentally friendly and causes less impact on established ecosystems. Similar to a wind turbine, many tidal stream generators rotate underwater and is driven by the swiftly moving dense water. Tides are more predictable than wind energy and solar power. Tidal power is the only form of energy which derives directly from the relative motions of the Earth-Moon (rotational) system, and to a lesser extent from the Eath-sun system. Basically a wind farm under the sea.
