➔ ¿What are the renewables energies?
➔ Solar energy
➔ Wind energy
➔ Seawater energy
➔ Wave energy
➔ Geothermal energy
➔ Fuel energy
➔ ¿What is Aerothermy?
➔ ¿How it works?
➔ ¿how it is possible to extract 77% of
➔ ¿What is the saving?
➔ ¿Why do not we use them at any time? ◆ Practical access to renewable
energies. ◆ Price. ◆ Technology.
Energy is a key factor in the development of companies.
I want to look for different reasons of the delay in the development of non-polluting energies.
We are going to see somes news tecnologies to get better those energies too.
What are the renewable energies ?
➔ They are renewed. ➔ They are environmentally sustainable. ➔ 7 % of the energy consumed in Spain is renewable. ➔ Spain is the tenth world producer. ➔ Kinds of energies:
◆ Solar. ◆ Wind power. ◆ Seewater energy. ◆ Wave energy. ◆ Geothermal energy. ◆ Bioenergy. ◆ Fuel energy.
➔ Renewable energy ➔ Obtain by the use of the electromagnetic radiation from sun. ➔ Many collectors:
◆ Photoelectric cells ◆ Heliostats ◆ Solar colectors
➔ Only 3% of the electricity production in Spain in 2016 is solar.
➔ Renewable energy. ➔ Obtained from the wind kinetic energy. ➔ Generated by the effect of air currents. ➔ At the end of 2016; 21.9 % capacity of the national electric system.
➔ Renewable energy. ➔ It is obtained with the tide. ➔ Use of an alternator. ➔ They want to create an i+d+i center on the coast of Santoña. ➔ It could attend to the consumption of 2500 homes.
➔ It obtain the electricity from the movement of waves.
➔ Maximum energy volume of 1.2 million MW per year.
➔ Renewable energy. ➔ It is obtained from the natural heat
of the interior of the earth.
➔ Renewable energy. ➔ Take advantage of organic and industrial matter. ➔ Is taken from the waste of living things. ➔ Respects the environment.
➔ It is not a green energy.
➔ Mixture of organic substances
➔ It has negative and positive environmental impacts
➔ Many underdeveloped countries destroy their natural spaces to create biofuel plantations.
¿Why don't we use these energies always?
➔ Practical access to renewable energies ➔ Price ➔ Technology ➔ The potential of this ecological energy is huge ➔ They could cover half of the world's energy needs in 2050.
Practical access to renewable energies
➔ We can not save renewable energy sources
➔ If the wind does not blow or we are before a cloudy day the capacity to produce energy decreases.
➔ It represents a problem when taking advantage of renewable energies.
➔ Fossil fuels are still cheaper sources of energy.
➔ A lot of energy is wasted
➔ The first step would be to make them cheaper
➔ Renewable sources produce clean and inexhaustible energy
➔ Could cover half of the world's energy needs by 2050
➔ They create jobs.
➔ Development and enactment are necessary.
