**Most of the energy used now can be replaced with sustainable energy.** In the recent 200 years parts of the earth' s environment has been destroyed, polluted, and contaminated in many ways. For example, industrialization, population explosion has caused Ozone disposal, climate change, deforestation, acid rain, global warming, animal extinction, and so on. The years before when the humans were industrializing they did not recognize the seriousness of the situation. Right now is a whole different story causing problems is not a problem, but knowing what consequence it would have on earth and human species and not changing is a problem. Some of the most important and most widely used methods to obtain energy are burning fossil fuel, coal, and gases. All these are used to operate factories, planes, cars, and other electronics that help make our lives easier. However, the problem is that burning fossil fuels, such as oil, coal, gases, and biomasses, can cause serious damage to the environment of the earth. These are the ones that cause global warming and climate change most seriously. Luckily, humans have the technologies and resources to replace these kinds of energy that pollute the earth. Some examples are wind energy, solar energy, tidal power, geothermal energy. Although, many people think sustainable energy is improbable and won’t be developed in their life time, recent researches have proved that most of the energies can be replaced with sustainable energy.

Surprisingly, wind power and solar energy are known to be inefficient because they cannot generate enough energy and they are impractical; however, people do not realize the true potential of these powers. According to a documentary film “Zeitgeist,” it states that the solar energy derived from the sun has such abundance that one hour of light at high noon contains more energy than the whole world consumes a year, and if human can capture one hundredth of that light it can be used as energy. Also, wind energy can generate energy just as much. The US department of energy admitted in 2007 that if wind was fully harvested in just three of the fifty states it could power the entire nation.

Aside from the solar and wind energy there is an energy called tidal power. This power as it can be seen from the name is generated from tidal sifts from the ocean. The turbines that were built under the ocean captures the movement of the tidal sifts and changes it to energy. This technology is now used in the United Kingdom and 42 sights are currently noticed as available and 34% of all the UK’s energy can come from this tidal power alone.

Among all the sustainable energy known one of the most powerful sustainable energy is geothermal energy. Geothermal energy can be created by a simple process using water and can generate mass amounts of clean energy. In 2006 an MIT report on geothermal energy found that 13000KJ of power is available in the earth and 2000KJ can be transformed into the energy we use now. What’s more surprising is that the total amount of the energy consumption of all the countries on the planet is 0.5KJ a year, which means that about 4000 years of energy can be harvested from geothermal energy alone.

Most people do not know the potential of sustainable and renewable energy. Most of them think that energies generated by sun, wind, water, and land are not very strong and efficient. They also believe that only fossil fuels such as oil, coal, gases, and biomasses are the only energies we can use. However, as stated previously, the United States and the United Kingdom has proved that sustainable energy can be used and can be replaced with oil and coal. New technologies are proving that renewable energy is possible and the world does not have to rely on polluting energies.
