Nopal, wind and photovoltaic energy

Energy of the cactus

It is generated by green plants that capture light energy from the sun and through a complex process called photosynthesis, transforms it into chemical energy, represented by organic molecules. This biomass produced is degraded through a process called anaerobic digestion, using specialized bacteria, this allows obtaining an energy-rich gas called Biogas, which corresponds to a mixture of methane, carbon dioxide, nitrogen and water vapor. Biogas is purified obtaining a 94% methane composition which is similar to natural gas. This gas is used as fuel in boilers, vehicles, buildings in a similar way to pipe gas.

Characteristics: Produce energy 24 hours a day, 365 days a year. Local jobs, It produces fuel (biogas), electricity and thermal energy such as hot water. Widely usable areas both at 40 degrees latitude south and north. Organic process, recovers soil, non-polluting.

Eolic energy.

It is obtained from the wind. It is a type of kinetic energy produced by the effect of air currents. We can convert this energy into electricity through an electric generator. It is a renewable energy that does not pollute and that helps to replace the energy produced through fossil fuels.

Characteristics: Widely known. Applicable in isolated areas with high wind regime. Its biggest problem is intermittence and unreliability in power generation. They are subject to environmental conditions. Their plant factor is their weakness, they only produce 30-40% of the time. Any alternative of storage in batteries makes the system unviable. Energy requirements may not match production.


Photovoltaic Solar Energy

It corresponds to renewable energy that is created after the direct transformation of radiation and light from the sun into electricity. This transformation is possible thanks to devices called photovoltaic panels, which convert the solar radiation hitting the photovoltaic cells. Therefore, photovoltaic solar energy mainly serves and is used to provide electricity both to companies and its distribution networks, as well as to individual or autonomous user devices.

Characteristics: It requires places with direct sun. The usable day is only 8 hours, considering 4 hours at sunrise and 4 at sunset where the panels do not generate energy, and of course, the night where there is no solar radiation. Its greatest advantage is its scalability, it can be installed in small towns to large areas. Values ​​have dropped every year, yet the energy storage problem continues. Some of the frequent problems is its high sensitivity to elements that block solar rays such as dust, shadows, humidity, scratches of the surface by fiction when cleaning the panels
