The review considers the main trends in global energy production and consumption over last half century, based on analysis made by P.L. Kapitza 1975 a unified approach using Umov–Poynting vector. Such aspects of problem as impact gross national product per capita, reasons for different approaches countries to transition renewable sources, existing sources energy, distribution its consumption, features prospects technologies, well technologies reduce are touched upon. Thus, since 1975, price one kilowatt-hour "solar" electricity has fallen orders magnitude this technology moved forefront, while fusion still remains "energy future" coal continues hold position market. Somewhat unexpectedly, electronics telecommunications have become major consumer urging shift from von Neumann architecture neuromorphic computers development femto attowatt optoelectronics.

Abstract Flexible piezoelectric energy harvesters (FPEHs) have wide applications in mechanical harvesting, portable device driving, and sensors. However, the poor output performance of intrinsic shortcoming sensors that can only detect dynamic pressure limit their further applications. BaTiO 3 (BT) PVDF are deposited on glass fiber electronic cloth (GFEC) by impregnation spin‐coating methods, respectively, to form BT‐GFEC/PVDF composite films. A mixed solution mechanoluminescence (ML) particles ZnS:Cu PDMS used as encapsulation layer construct a high‐performance ML‐FPEH with self‐powered electrical optical dual‐mode response characteristics. Due interconnection structure films, prepared illustrates high effective harvesting (≈58 V, ≈43.56 µW cm −2 ). It also effectively harvest from human activities. More importantly, sense stress distribution hand‐writing via ML achieve visualization, making up for shortcomings This work provides new strategy endowing FPEH sensing harvesting.
