What are the different types of renewable energy project?
The renewable energy project is a project to generate energy in a sustainable way by not using exhaustive natural resources such as fossil fuels. Nuclear energy is not considered sustainable because it requires mining of non -renewable uranium deposits. Renewable energy projects use a wide range of energy sources that can be divided into four main types: light, heat, kinetic and chemical. Solar energy is an example of light as an energy source; Solar and geothermal energy are examples of heat as energy sources; Hydroelectric force, wind, wool and tidal force are examples of kinetic energy or energy of movement; And the energy of biomass and biofuels are examples of chemical energy or energy locked in chemical compounds that can be released by combustion.
Although heat can be used directly for thermal buildings, the usual goal of the renewable energy project is to generate electricity. Solar energy can produce electricity through photoelectricThe effect, which produces electricity when exposed to light, but most of the electricity are produced by turbines that could be powered by steam produced by natural heat sources or directly sources of kinetic energy. Biofuels could be used directly for power vehicles as an alternative to fossil fuels.
Concerns about the exhaustion of non -renewable energy sources led to extensive implementation of renewable energy projects. Climate change, pollution and nuclear power safety are also concerned that have contributed to the search for renewable energy. Much of the research has come to finding efficient and cost -effective ways of using renewable energy sources.
solar energy can be used in two main ways. Photovoltaic cells, often called solar cells, convert light directly to electricity and can be grouped into large solar panels that generateNo amount of energy. They can be used on a small scale to ensure electricity to households or in large fields for extensive electricity production.
Another method of using solar energy is by means of mirrors to focus solar energy on the target. This generates heat so that it controls a power plant that could produce a pair to control the turbine or use the heated gas extension to drive the piston. Alternatively, heat can be used on a smaller scale to ensure hot water or for cooking.
Renewable energy project based on geothermal energy uses heat from Earth core as a source of energy. It will not happen for billions of years, so it is considered renewable. Alternative energy projects could use geothermal energy using natural hot water near the surface to heat buildings or pump water into heat sources deep underground and convert it to pairs to turbines.
extensive hydroelectric projects use potential energy of elevated waterH formations using gravitational water flow to the turbine drive. These projects require suitable terrain and considerable amount of surface water, and most of the water systems included the construction of dams and floods of land areas. Smaller scale projects including running water from the river were also implemented.
Wind energy is used using wind turbines. They usually consist of three blades mounted on a metal column. Turn the blades drives the turbine to produce electricity. Wind turbines can be installed individually to provide energy for buildings, but for extensive electricity production, they must be installed in large numbers and create "wind farms" covering large areas of soil.renewable energy projects based on wave and tidal energy create electricity by movement of ocean water. The wave generators use the movement of ocean waves and relies on the transformation of the movement of the wave into rotacials. This could be achieved by coastal plants that use incoming wavesTo enforce air through the chamber to a turbine or coastal structures that capture the kinetic energy of the waves, and use them to pump fluid into the coastal plant. There are many designs, some include long, flexible tubes that float on the surface, and some include suspended barriers that move back and forward.
tidal energy can be captured by means of fire that acts as a dam across the mouth of the tidal river. Water from incoming or outgoing tides is forced to drive the tunnels. Although the potential of energy generation is considerable, tidal baricles only create electricity when the influx flows and may disrupt the fine ecosystems.
The Biomass Renewable Energy project uses chemical energy locked in organic materials. These projects can use biomass directly by burning agricultural waste or use it to produce alternative fuels, such as ethanol from Sugyr cane fermentation or methane from waste water and animal waste. Although jThese sources are renewable, biofuels produce carbon dioxide as well as fossil fuels, so many people believe that they contribute to climate change.
