The world that is moving increasingly to the care of the environment, coupled with the exploitation of non-renewable resources that has led to the increasingly thorough search of viable, economical and clean energy resources. Researchers advance to ensure that the sources of most widespread energy such as the sun or wind, to compete directly with fuels fossils. In addition, it progresses in incorporating new resources, such as seaweed or methane produced during the putrefaction of organic materials. Following is a review of some elements of everyday life that can be transformed into energy.
In Spain, developing the “Pavener Project” is a technology that is being developed to tap the heat that build up in the asphalt. This type of soil can accumulate up to 70 degree temperatures on sunny days. The project is based positioning system pipes under roads, through which circulate a fluid that could be used as energy for refrigeration and heating.
The ability of waves to travel long distances without loss of energy has become an important renewable energy resource. The force generated in the ocean just reaching the shore, where you can collect and transform for human use. The tide is transformed into electricity in tidal power stations. This occurs by a combination of surface and bottom, joined the lunar and solar influence. The advantage is that the energy released by the rise and fall of the waves, which is technically called ebb and flow.
Shanwen Tao and Rong Lan, two researchers from Heriot-Watt University in Scotland, have developed a project called Carbamide Power System. This prototype power becomes a chemical compound ethyl is present in the urine of animals and humans. Some of the uses that could give you have to do with electricity in submarines and supply power to villages in the middle of the desert.
Hydrogen is the most abundant component in the universe. It is used for the space industry and transportation for their utility in the propulsion of vehicles. You can replace all types of energy sources, such as batteries, motors or batteries. However, it is a highly flammable and difficult to get gas itself. Currently, it is obtained through fossil fuels, but in the future it could be through renewable and inexhaustible energy. Several automakers are producing cars that run on hydrogen, which predicts that will reach a situation in which he will be the main source of energy.
Wind energy is generated by wind, by exploiting the kinetic energy produced by currents of air. While it may appear as a non-polluting or damaging alternative, it has detractors. It happens that in order to replace the energy, for example, thermal centers, a large number of mills with an average height of 90 meters that make up a wind farm are necessary. The presence of these wind turbines impact on ecosystems and cause visual pollution to humans. However, to supply energy to a family only takes a mill with a height of 15 meters.
Heat from the ground (Geothermal Energy Options)
Geothermal energy is the science that is responsible for studying the phenomena related to the temperature of the earth to use them in the form of renewable energy. This is a very economical and completely natural resource. It is characterized by its large savings in carbon dioxide emissions. The devices that collect this energy are installed below ground, so do not generate any visual impact, or the health of humans or the environment. If you find any area with water to drill to place the heat collectors, the performance will be higher because it is a good conductor of heat.
The mixing of fresh water from rivers with the salty ocean water releases high amounts of energy. This type is known as osmotic power or blue. The process of obtaining, ie the combination of water, occurs in all estuaries in the oceans, generally located in urban or industrial areas. Power plants may be constructed partially or totally underground, minimizing the visual impact on the environment. In addition, you can take precautions to not impact biotypes river or ocean, or in stream.
All organic materials are potential decomposition, a natural process in which noxious gases into the atmosphere are emitted. Especially methane and carbon dioxide, the greenhouse facilitators are released. Methane can be used to operate a producing electricity or fuel engine. In this process, the gas is burnt and disappears. The capture biogas plants that do not require high costs. Moreover, waste from the putrefaction appear also in the solid state, resulting in a good soil fertilizer and liquid, also plausible for agricultural use as fertilizer.
Cooking oil is highly polluting if, after used, pour it down the drain and ends up in drains. Experts recommend collect it in bottles and take to recycling centers. Through various processes, plants get biodiesel, a fuel made from waste components with the potential to replace fossil fuels. Although their production is more expensive than hydrocarbon processing, the main advantage is that it is a renewable good. Planes, buses and shared among vehicles already conducted tests or work with certain percentage of biodiesel.
Sugar fermentation results in a compound that can be used as fuel called bioethanol. This resource for energy is subject to much controversy: for some it is potentially sustainable and provides environmental and economic advantages over fossil fuels, while for others its misuse can lead to deforestation and rising food prices, the supplanting forests and agricultural land for production. The use of bioethanol for vehicles is widespread in some countries. For example, in Brazil service stations offer both fossil-based fuels like ethanol-based.
The algal fuel is a biofuel made from seaweed. While it is in the process of research, experts estimate that play an important role in replacing fossil fuels. Among the many virtues you can enumerate the possibility to find algae in almost any aquatic ecosystem, both salty, sweet or wastewater. They not require water and can be placed in any type of soil. They just need sunlight to survive. In turn, assist in the removal of gases that cause the greenhouse effect because your metabolism is based on capturing light and carbon dioxide to grow.
