In view of the questions that heavy oil has badly flow condition and lifting efficient, and considering low carbon, energy conservation and environment as goal, an advanced artificial lift technology of cyclic nature gas heat insulation and geothermal temperature heating is developed, and the temperature calculation model of the technology was founded. The analysis that different cyclic nature gas volume, cyclic depth and oil production affect the formation produced fluid temperature distribution was made. The result is that the formation produced fluid temperature increases with the addition of cyclic depth and the function of rising temperature decreases from cyclic depth to wellhead, and that the formation produced fluid temperature increases with the addition of oil production and cyclic nature gas volume. A certain well as example, using the technology, the formation produced fluid temperature increases 11.14°C, compared to the conventional artificial lift technology. And it is favorable for surface transportation.

It is advanced here that a principle-based approach is needed to develop the energy sector during and after COVID-19. The economic recovery that is needed needs to revolve around ensuring that no one is left behind, and it should be an inclusive transition to a secure and stable low-carbon energy future. There are seven core energy law principles that if applied to the energy sector could enable this to be achieved.

Rapid decarbonization requires additional research, development, and demonstration of low-carbon energy technologies. Various financing instruments are in place to support this development. They are frequently assessed through indicator-based evaluations. There is no standard set of indicators for this purpose. This study looks at the Nordic countries, which are leading countries with respect to eco-innovation. Different indicators to assess financing instruments are analysed with respect to their acceptance, the ease of monitoring, and their robustness. None of the indicators emerges as clearly superior from the analysis. Indicator choice is subject to trade-offs and leaves room for steering evaluation results in a desired direction. The study concludes by discussing potential policy implications of biases in indicator-based evaluation.

The world is at a pivotal crossroad in energy choices. There is a strong sense that our use of energy must be more sustainable. Moreover, many also broadly agree that a way must be found to rely increasingly on lower carbon energy sources. However, no single or clear solution exists on the means to carry out such a shift at either a national or international level. Traditional energy planning (when done) has revolved around limited cost projections that often fail to take longer term evidence and interactions of a wider set of factors into account. The good news is that evidence does exist on such change in case studies of different nations shifting toward low-carbon energy approaches. In fact, such shifts can occur quite quickly at times, alongside industrial and societal advance, innovation, and policy learning. These types of insights will be important for informing energy debates and decision-making going forward. Low Carbon Energy Transitions: Turning Points in National Policy and Innovation takes an in-depth look at four energy transitions that have occurred since the global oil crisis of 1973: Brazilian biofuels, Danish wind power, French nuclear power, and Icelandic geothermal energy. With these cases, Dr. Araújo argues that significant nationwide shifts to low-carbon energy can occur in under fifteen years, and that technological complexity is not necessarily a major impediment to such shifts. Dr. Araújo draws on more than five years of research, and interviews with over 120 different scientists, government workers, academics, and members of civil society in completing this study. Low Carbon Energy Transitions is written for for professionals in energy, the environment and policy as well as for students and citizens who are interested in critical decisions about energy sustainability. Technology briefings are provided for each of the major technologies in this book, so that scientific and non-scientific readers can engage in more even discussions about the choices that are involved.
