Near Future

In the energy field and more specifically in the petroleum sector, several models have been developed with a view to determining long-term price strategies and supply and demand flows without considering the sector in question from an oligopolistic perspective : institutions have been excluded from these models. This study explicitly recognizes the importance of variables often characterized as extra-economic and proposes to examine the degree of OPEC's stability. Among the factors that could negatively influence this stability are bilateral oil agreements, the coalition of consumer countries within the International Energy Agency and rivalry among the members of OPEC. The respective weight of each of these factors has been carefully examined. On the other hand, an oil price indexing formula accepted and respected by all parties concerned would ensure the stability of this organization. However, stability via indexing is unlikely as it is difficult to find a formula acceptable to all parties. It is therefore to be anticipated that the world energy and petroleum situation in the near future will be a function of the policies of the two poles : the United States, the largest consumer, and Saudi Arabia, the largest producer. The functions-objectives of these two countries have also been examined in order to derive a number of specific hypotheses relative to the eventual evolution of the energy and petroleum sector.

Positive Effect

AbstractGlobal energy demand increases overtime, especially in emerging market economies, producing potential negative environmental impacts, particularly on the long term, on nature and climate changes. Promoting renewables is a robust policy action in world energy-based economies. This study examines if an increase in renewables production has a positive effect on the Brazilian economy, partially offsetting the SARS-CoV2 outbreak recession. Using data on Brazilian economy, we test the contribution of renewables on the economy via a ML architecture (through a LSTM model). Empirical findings show that an ever-greater use of renewables may sustain the economic growth recovery, generating a better performing GDP acceleration vs. other energy variables.

World Energy

Some 1% of the earth's crust has heat flux significantly above the global average. Concentrated in areas of the order of 10km2 associated with volcanic zones, such energy can be tapped for local power projects commonly generating 10MW km2. Such systems are of great value to those areas of developing countries, and elsewhere, lucky enough to possess this resource, but could never be seen as a ‘solution’ to the world energy problem. Long-term effects of field development are unknown, for instance development of the Wairakei field in New Zealand has only been active for 25 years. The vital choices for management of such fields are in how quickly energy is required, and how much. These choices will dertermine whether the resource must be ‘mined’ or whether it is possible to recharge the system and maintain a long-term supply. If the former, geothermal energy must be regarded as a ‘finite’ resource, for it is non-renewable, unless fluid extracted is replaced. Mining, resource definition, field development and theoretical background to these aspects are discussed and illustrated using a model of a typical development.

Effective Development

The analysis of recent trends in the world energy development and of long-term energy development projections helps dispel 10 myths that have been viewed as copybook maxims, yet now are a barrier to forming an adequate vision of the future and effective development strategies. Many of these myths are rooted in the inability to see how the ‘small on small scale’ becomes ‘big on big scale’ , and vice versa. Projection horizon to 2050 allows to see these metamorphoses, formulate the ‘lessons of the future’ for Russia’s economic development, and to show why Russia needs to change its economic model and switch to low-carbon development path.

International Attention

“Changing Atmosphere – Implications for Global Security”, Toronto 1988, attracted international attention to the dangers of the greenhouse effect. It focused attention on the need for cleaner primary energy sources and energy carriers. This implies not only greater efficiency and conservation but also a move away from high carbon content fuels. There will be increasing pressure on decision makers to take appropriate action in complex and difficult matters that will have profound political, social and economic implications. Hydrogen has an important role as an energy source in the short, medium and long term. Early applications of hydrogen include the enrichment of hydrogen-deficient oils and solid fuels, its role in the replacement of gasoline in urban vehicles, its use as an energy-storage medium for load-levelling, and for the transportation of large quantities of energy when other means are not available. In the long term it could become a principal world energy currency. In this role it is compatible with and complementary to electricity.
