energías renovables en ingles 2
TRANSCRIPT
These include wind, thermal, geothermal, etc. we will present the three already mentioned that
were chosen to develop
Is the energy from the wind, that is. the kinetic energy generated by the effect of air currents. Wind energy is an abundant, renewable, clean and helps reduce emissions of greenhouse gases to replace power plants based on fossil fuels, which makes it a kind of green energy. Its main drawback is the intermittency of wind
It is currently used primarily to move turbines. These wind power and drives a propeller through a mechanical system rotates the rotor of a generator, usually an alternator, which produces electrical energy. To be installer profitable, usually grouped in concentrations known as wind farms. A mill is a machine that transforms the wind into usable energy, which comes from the action of the wind on oblique vanes attached to a common shaft. The rotary axis can be connected to various types of machinery to grind grain, pump water or generate electricity. When the shaft is connected to a load such as a pump, called the windmill. If used to produce electricity is called wind turbine generator. The mills have a remote source.
It is a type of renewable energy because it comes from atmospheric processes due to the energy that reaches Earth from the Sun
It is a clean energy because it produces no air emissions or polluting waste.
No external combustion produces carbon dioxide (CO2), so it does not contribute to the greenhouse effect and climate change.
Can be installed in areas unsuitable for other purposes, for example in desert areas near the coast, in arid and very steep slopes to be arable.
It can coexist with other land uses, such as meadows for livestock use or low crops like wheat, corn, potatoes, beets, etc..
Create a large number of jobs in assembly plants and installation areas.
Installation is quick, from 4 months to 9 months
The following is the thermal energy development
Thermal energy is that it produces heat that is generated because of inelastic collisions of the particles constituting the materia.Suscharacteristics: It is easy to obtain: kinetic energy is required merely because it automatically produces heat.
It is renewable: never ends, because there is always present kinetic energy (in atomic particles that are in constant motion, it generates an extremely low amount of heat, but is constant at all times. Rubbing our hands, in times of cold, are doing kinetic energy, which generates heat). In addition, the sun is a constant source of energy at all times
Polluter: power plants produce emissions, mainly CO2 (carbon dioxide), which reach the atmosphere and pollutes the environment
It is renewable.
It can produce many products.
It can be converted into electrical energy, which serves to operate machines that require electricity, light bulbs, etc..
Greater availability of this energy, they are always ready to be worked
The collection and use of this energy involves an environmental impact.
To work this energy, use fossil fuels such as coal and oil, which release a lot of toxic gases for life.
Combustion releases carbon dioxide (CO2) emissions.
And finally develop geothermal energy
It is that which can be obtained by harnessing the heat from inside the Earth
In areas of very hot thermal waters at shallow depths, it uses heat from inside the earth. The hot water or steam can flow naturally, by pumping or pulsed flow of water and steam.
It is a source avoiding dependence on foreign energy. The waste produced is minimal and cause less
environmental impact than those caused by oil and coal.
Great savings system, both economic and energy. No outside noise. Geothermal resources are greater than the resources of
coal, oil, natural gas and uranium combined. Not subject to international prices, but you can always
keep national or local prices. The area of land required for geothermal plants is
smaller per megawatt than other plants. Does not require dams, logging, and construction of pipelines (gas or oil pipelines) or fuel storage tanks.
The emission of CO2, with increased greenhouse is lower than would be issued for the same fuel energy.
In some cases emission of hydrogen sulfide is detected by its odor of rotten eggs, but in large quantities is not paid and is lethal.
Water Pollution coming with substances like arsenic, ammonia, etc..
Thermal pollution.
Deterioration of the landscape.
You can not transport (primary energy).
It is available only in certain places.
Electricity generation.
Direct use of heat.
Heating and plumbing.
Absorption cooling.
And with that we finished our presentation last
