HISTORY AND USE OF RENEWABLE ENERGIES

1. LAWS OF THERMODINAMIC
1. 1. Energy is neither created nor destroyed, it only changes
2. 2. All energy is constantly degraded into a usable form of energy
2. HISTORICAL CONCEP
1. 1. Use and command of fire
2. 2. Agricultural and livestock, use in the form of food
3. 3. Transports with the investment of the wheel
4. 4. for the 20th century BC *
  1. wind sail
  2. waterwheel
  3. Windmill
5. 5. Century XVIII
  1. steam machine
6. 6. FOR THE CENTURY XIX
  1. first oil well
7. 7. FOR THE CENTURY XX
  1. VIGOROUSLY INCREASE ENERGY USE
3. Types of energy
1. Renewable energies are those that are obtained from inexhaustible natural sources and generate electricity without contributing to global warming.
2. Non-renewable energies are stored underground or on land for millions of years, for example coal, natural gas, etc
3. Solar thermal energy or solar thermal energy consists of harnessing the sun's energy to produce heat.
4. Photovoltaic energy is the direct transformation of solar radiation into electricity. This transformation occurs in devices called photovoltaic panels.
5. Wind energy is that which is obtained from the force of the wind.
6. Biomass It is the energy that can be obtained from organic compounds formed in natural processes.
7. Geothermal energy is a renewable energy that is obtained through the heat that comes from the interior of the Earth. It manifests naturally through hot springs, geysers or volcanoes. It is generally used for cooling, heating, supplying drinking water and generating electricity.
8. La energía hidráulica es la obtenida del agua en movimiento. La fuerza del agua se transforma en energía mecánica al mover las aspas de una turbina en una central hidroeléctrica, donde se transforma en energía eléctrica
9. The sea has a great energy potential, which is manifested mainly in waves, tides, currents and in the difference in temperature between the surface and the seabed
4. Advantages of renewable energy
1. when renewable energy sources are used to generate electricity, they are much cleaner than conventionally used fuels
2. Renewable energy generation plants produce little or no gas emissions
3. The main advantage is the practically zero emission of greenhouse gases (GHG) and other pollutants that contribute to climate change.
4. They help reduce pollution-related diseases.
5. Disadvantages of renewable energy
1. High visual impact: if we want to obtain large amounts of energy, it is necessary to create large-scale solar plants. ...
2. Unequal geographic resources: basically this means that not all geographic areas have the same natural resources.
3. Large tracts of land
4. High investment cost.
5. Weather dependent
6. Sunlight variability.
7. Population centers far from power generation centers.
8. Disposal and recycling of toxic materials. ..
9. Low energy production efficiency.
