Multiwavelength studies of MHD waves in the solar chromosphere: An overview of recent results

The chromosphere is a thin layer of the solar atmosphere that bridges the relatively cool photosphere and the intensely heated transition region and corona. Compressible and incompressible waves propagating through the chromosphere can supply significant amounts of energy to the interface region and corona. In recent years an abundance of high-resolution observations from state-of-the-art facilities have provided new and exciting ways of disentangling the characteristics of oscillatory phenomena propagating through the dynamic chromosphere. Coupled with rapid advancements in magnetohydrodynamic wave theory, we are now in an ideal position to thoroughly investigate the role waves play in supplying energy to sustain chromospheric and coronal heating. Here, we review the recent progress made in characterising, categorising and interpreting oscillations manifesting in the solar chromosphere, with an impetus placed on their intrinsic energetics.Comment: 48 pages, 25 figures, accepted into Space Science Review

Long-term Scenarios of Global Power Industry Development: Main Tendencies and Uncertainties

Scenario analysis of world electricity in the long-term perspective within the general context of global economic growth allowed the authors to conclude that perspective dynamics of electricity in the world leading production and consumption centers will be decisively influenced by complex and heterogeneous factors, including: first, primary energy resources endowment; second, level and type of economic development; third, countries capacities to mobilize financial and investment resources necessary for promotion of new renewable energy sources; fourth, national economic and energy strategies. Depending on these factors countries will remain at very different stages of energy transition at the foreseeable future. There is no a universal model of energy transition
