An energy derived from renewable resources such as wind, water and sunlight, that is alternative energy. The word “alternative” promotes an understanding that these energy are used to replace a certain energy, such as the fuel energy, and are expected not to give the same consequences as the replaced energy. As we all know, alternative energies are better, environmentally speaking, than our chemical source of energy.These renewable resources includes the wind, sun, hydrogen, biofuel and geothermal. Special devices intended for each resources are constructed in order to store energy. A wind turbine is the main tool in generating energy from the wind while solar panels are used to store energy from the sun. For hydrogen, the stronger the gush of water the stronger the energy could be driven out. That is why, the machine used in generating hydrogen energy are commonly set under the gushing water of falls. However, even a simple wood could be a source of alternative energy. It is said that burning of wood could emit the same amount of carbon as it is degrading naturally.
It may be complicated and costly to generate an energy from these resources, yet we ought to remember that the method in generating oil, fuels and natural gas are more complicated. These energy are involved in a physical and chemical process which requires a very complex machine. Aside from being difficult, it could also be harmful. One example would be the nuclear energy. Just a tiny piece of atom could literally destroy everything. It is an advantage that scientist are looking for ways to alter these effects without compromising the use of energy.Carbon dioxide emission from the burning fossil fuels are an example of why people are finding new ways to generate energy without causing much harm to the environment. In fact, Carbon dioxide is believed to be the main reason of global warming. There are a lot of elements and chemicals emitted by some energy that is really harmful not only to the environment but also to the human health as well, that is why scientists never lose hope to find new sources of energy.
Change is a choice. There is no harm in trying any possible ways to save the environment. It is never too late. Let us just be thankful that there are people who are willing to take chances with alternative energies. Alternative energies are finding ways to take place and be in charge in providing our world the energy that we need and still be able to live in it.
