Abstract

This paper explores the technical and economic characteristics of an accelerated energy transition to 2050, using new datasets for renewable energy. The analysis indicates that energy efficiency and renewable energy technologies are the core elements of that transition, and their synergies are likewise important. Favourable economics, ubiquitous resources, scalable technology, and significant socio-economic benefits underpin such a transition. Renewable energy can supply two-thirds of the total global energy demand, and contribute to the bulk of the greenhouse gas emissions reduction that is needed between now and 2050 for limiting average global surface temperature increase below 2 °C. Enabling policy and regulatory frameworks will need to be adjusted to mobilise the six-fold acceleration of renewables growth that is needed, with the highest growth estimated for wind and solar PV technologies, complemented by a high level of energy efficiency. Still, to ensure the eventual elimination of carbon dioxide emissions will require new technology and innovation, notably for the transport and manufacturing sectors, which remain largely ignored in the international debate. More attention is needed for emerging infrastructure issues such as charging infrastructure and other sector coupling implications.

  • The classical SWOT analysis, described by Weihrich, can be perfectly applied in this case.

    “Although there are more complex approaches to the analysis of the subject matter, such as the hybrid decision-making method developed by Naeini et al. [17], the classical SWOT analysis, described by Weihrich [18], can be perfectly applied in this case.”

    From The Perspective of Large-Scale Production of Algae Biodiesel (2020) · cites this paper as [18]

  • Fossil fuels meet approximately 80% of energy needs but increasingly demonstrate negative environmental impacts from air pollution, climate change, dwindling finite supplies, and volatile prices.

    “Fossil fuels meet ~ 80% of energy needs but increasingly demonstrate negative environmental impacts from air pollution due to climate change, alongside dwindling finite supplies and volatile prices [49, 62, 63].”
  • Researchers are investigating nanotechnology, new catalysts, biorefinery designs, genetic engineering to increase energy crop yields, and reducing costs of cellulosic ethanol and other advanced biofuel technologies to increase efficiency and sustainability of biofuel production.

    “For example, researchers are investigating the use of nanotechnology to increase biofuel production [158], improve biofuel production efficiencies through the use of new catalysts, and biorefinery designs, utilize biotechnology such as genetic engineering to increase energy crop yields, and continue to reduce the costs of cellulosic ethanol and other advanced biofuel technologies [49, 130].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
