This chapter examines the emergence of a modern energy regime in Europe. It begins with a discussion of the increase in energy consumption and how a combination of coal, engine, and iron coalesced to form the “development block” that characterized and drove the first industrial revolution. It then considers the role of coal in the new geography of energy supply, divergence in energy regimes, and urbanization and pollution. It also describes the rise and relative decline of traditional energy sources such as calories from the soil, food demand, working animals, firewood, water power, and wind power. The chapter shows that the amount of renewable energy available to each inhabitant in Europe was falling in the case of every single carrier except food, as population growth outstripped supply.

The Role of the Latvian District Heating System in the Development of Sustainable Energy Supply The aim of the study is to determine whether and to what extent it is possible to use excess electricity produced by wind power plants during low demand periods for district heat production by heat pumps. Energy system analysis on an hourly basis is conducted at various capacities of wind power plants. The results show that it is possible to increase the share of renewable energy sources, decrease the use of primary energy sources and CO2 emissions per unit of the produced energy, i.e. heat and electricity, by using the surplus electricity produced by wind power in the heat pumps combined with the heat storage.

The article consider the role of energy factor in historical process of the first three industrial revolutions. The efficiency of modern alternative energy sources compared with traditional sources is being studied, as well as prospects for "green" energy sources to become a resource base for economic growth and a new technoeconomic paradigm. The potential of the modern energy resource base to provide mass automation of production cycles is being estimated.

The role of the power supply device is to produce, process and distribute energy sources. Telecommunication equipment can only operate if it has continuous supply. Therefore, to maintain the continuity of the supply, a UPS (Uninterruptable Power Supply) device system is needed so that the supply to the Essential Load device will remain available so that continuity will be maintained. This research designs and proposes how a series of automatic redundant switch systems on UPS to ensure the availability of power supply for the main equipment of telecommunications systems. The Auto switch circuit is designed to have 3 (three) working stages which will trigger the relay driver as control circuit, namely the normal working condition of the contactor input K1 is present, the input condition is zero (lost), and the input condition is present. This system can automatically supply power to telecommunications equipment.

The economic diversification concept gives hope for a country with rich natural resources to strengthen its economic basis. Thus industrial revolution era of 4.0 provides great opportunity to fasten the process. A study by McKensey in 2011 proved that the internet in the developing country contributes around 3.4% towards its GDP which means that the internet has become a new hope for the economy in the future. Indonesia is one of the countries that is attempting to maximize the role of the Internet of Things (IoT) for its economic growth.� The attempt has made the retail and tourism industries as the two main sectors to experience the significant effect of IoT. In the process of optimizing the IoT to support the economic growth, Indonesia faces several issues especially in the term of the internet network quality and its distribution, the inclusive access of financial access and the infrastructure
