Evolution of Energy

By -

From the evolution of man on earth from early man to the technological geek, oil has become the major source of energy which was extracted from different sources. Some of the key sources are as follows from 18th century to till data.



Energy History and the evolution of mankind from Early Man to Modern Man 

 

The evolution of energy took place from the 15th century with the gradual development of technology. As man is developing himself from the early man stage to the highly intelligent person on the planet several technological changes took place in the development of energy and power division. With the following time you may understand the evolution of the energy sector in the world.

  

18th century

  • Industrial revolution
  • Use of energy relied only on muscular and biomass energy (main firewood used for heating and cooking purpose
  • Work is done with the help of labors and animals
  • Other sources of energy such as windmills, and watermills were present but the overall contribution was marginal

19th century

Major source of energy shifted to coal mainly in this process the technology development took place with steam engines and power plants which depend on coal as a primary source of fuel to run the systems.

20th century

 


History of energy use

The major resource available on earth is coal which is at a lower price but the shift towards the higher energy content sources like oil was beginning. 

In the second phase, a major shift was mad in internal combustion engines and oil-powered ships. Petroleum products as the main provider of energy reached a high level of dependence in the world economy. level of technical expertise increased, more efficient sources of fossil fuels were tapped, such as natural gas, and an entirely new form of energy, nuclear fission, became available. Renewable sources of energy, such as hydroelectric, wind, and solar started to be tapped but remained marginal sources

 

21st Century

  • Major shifts in energy sources with the obsolescence of fossil fuels, like coal and oil, for more efficient fossil fuels such as natural gas
  • Sustainable ‘clean coal’ technology potential. Advances in biotechnologies, underline the growing potential of biomass-derived fuels while wind and solar energy will also account for a notable share of energy sources.
  • Nuclear energy, particularly if nuclear fusion becomes commercially possible, may also play a significant role, but this remains speculative.
  • A new transition is likely to be the usage of hydrogen, mainly for fuel cells powering vehicles, small energy generators, and portable devices.

Solar panels installed on the roof with a capacity of 11.5 MW in Punjab state in India India’s solar mission which has kept at a target of 175 GW and the government is trying to keep its word to generate power from all kinds of Renewable Energy Resources. As it is focused on Solar, Wind and Biomass power generation technologies. We all know that a roof is the zero cost of land and uses the space for solar panel installation. There is no requirement of a special setup is installing the solar roof. Depending upon the roof size and shading and direction of the sunlight is considered for setting up the solar panels. But, most of them have small or medium roofs that can generate in kiloWatts (kW) or Megawatt (MW) scale. In Amritsar, there is an installation od 11.5 MW capacity of a solar power plant which is completely covered with solar roof which will benefit 8000 households was built by Radha Saomi Satsang Beas (RSSB), a religious organization in Punjab.

In most of the western countries and developing countries are launching the new concept called the “ Recycling Malls ” in major cities and towns across their countries. The main objective of the recycle mart is to sell the used products (ex: used plastic, glass, paper, etc.). This is an innovative way of making things and helping in reducing environmental pollution in the surroundings across the globe.   There are different kinds of pollutions that are generated effecting Air, Water, Land, Food, Sea, Ocean pollutions. It is damaging the EARTH gradually and impacting directly and indirectly that are highly toxic and increase the scope of new harmful viruses etc.   Issue: Wastes are different types that are generated in the world which is mostly produced by man. Anything that is produced excess and unable to control is added into pollutant list. The recycling plants are getting adopted across the globe with different techniques, methodologies and Strategic ways in collection

Honda is one of the popular brands in the Indian automobile industry. with the Activa petrol scooter with multiple versions, the company is come up with an electric version which Indian consumers are awaiting for the same. Apart from their plans to launch the electric vehicle in the Indian market, some of the key points are strong enough for Honda can capture a great EV market share in the country. Kinetic Honda is the predecessor for Honda Activa which was a big hit in 90s.  Year wise Activa Models released by Honda:  2001,  2002,  2007,  2008,  2009,  2018,  2019,  2020,  2021 Some of the key advantages for Honda can be a great EV market giant compared with startups and OEMs due to the following: Charging facilities in service stations: As Honda has 334+ service stations [1] across various states in India, the majority of them are bigger compared to other two-wheeler service stations. So a large charging infrastructure network and facility can be developed which can provide easy ac

India is witnessing a new chapter in the growth of the renewable sector, mainly in the solar sector. Hence, any new breakthrough in the field of solar cells and solar power generation is beneficial for India. New technology is being developed in the University of Chicago within the confines of its chemistry laboratory by Professor “Luping Yu”. A new kind of solar panel was designed and manufactured which has a higher efficiency when compared with the currently running modules used for power generation. The given polymer solar cell consists of a new polymer, called "PID2". The new polymer improves the efficiency of electrical power generation by 15 per cent when added to a standard polymer-fullerene mixture. New light has been shed on solar power generation using devices made with polymers. Researchers identified a new polymer a type of large molecule that forms plastics and other familiar materials which improved the efficiency of solar cells. The group also determined th

The Indian government has kept a target of 175 GW installed capacity using different renewable energy technologies in the country. Currently, the total installed capacity of the country is 367.3 GW of which thermal is 230.72 GW , Nuclear is 6.78 GW , Hydro is 45.4 GW and RE is 84.4 GW as on 31.12.2019. For the month of December 2019 the electricity generated in different power segments is 86.1 BU in thermal, 3.6 BU in Nuclear, 8.9 BU in Hydro and 9.3 BU in RE [1] . Currently, the total renewable installed capacity is 57.472 GW ( 12.5 GW of solar i.e., 21.8% and 32.3 GW of wind i.e., 56.2% ).  Depending upon the current installation frequency, we can forecast whether we can reach the target by 2022 or 2030 .
