Definición

  • Energy transition is a significant structural change in an energy system. Historically, these changes have been driven by the demand for and availability of different fuels. Energy transitions can also result from depletion of energy sources, for example whale oil for illumination and wood for iron smelting in Europe. The current transition to renewable energy, and perhaps other types of sustainable energy, differs as it is largely driven by a recognition that global carbon emissions must be brought to zero, and since fossil fuels are the largest single source of carbon emissions, the quantity of fossil fuels that can be produced is limited by the COP21 Paris Agreement of 2015 to keep global warming below 1.5 °C. In recent years, the term energy transition has been coined in the framework of a move towards sustainability through increased integration of renewable energy in the realm of daily life. An example of transition toward sustainable energy is the shift by Germany (Energiewende) and Switzerland, to decentralized renewable energy, and energy efficiency. Although so far these shifts have been replacing nuclear energy, their declared goal was the coal phase-out, reducing non-renewable energy sources and the creation of an energy system based on 60% renewable energy by 2050. As of 2018, the 2030 coalition goals are to achieve 65% renewables in electricity production until 2030 in Germany. Another such example is the drive to transition from internal combustion engine powered vehicles to electric vehicles as a way to reduce the global reliance on fossil fuels and reduce greenhouse gas emissions. This transition in particular however has begun to stimulate debate considering it requires a tenfold increase in mineral extraction and therefore will lead to an increase of the mining processes themselves and of the associated environmental and societal impacts. A potential solution that has arisen for this energy transition dilemma is to explore collection of minerals from new sources like polymetallic nodules lying on the seabed. Ongoing research is exploring this as a way to facilitate the energy transition in a more sustainable manner. (Source: DBpedia)
