Despite all efforts, there is currently no sustainable city in the world. In some cities there are positive changes towards sustainability (RES instead of fossil fuels, using electric cars, waste recycling, reduction of CO2 emissions, etc.), but in order to achieve the sustainability of the Earth as a planet, all cities in the world should be made...

Considering that more than half of the world’s population today lives in cities and consumes about 80% of the world’s energy and that there is a problem with drinking water supply, this paper presents a way to solve the problem of the sustainability of cities by enabling their complete independence from external sources of energy and drinking water...

There is a broad consensus worldwide that anthropogenic climate change is a scientific fact. Likewise, the fact is that the UN’s efforts to address climate change over the last 28 years have not been successful enough. It is evident that the global average temperature is on the rise (1.1 °C above pre-industrial levels in 2019). A particular concern...

By doubting the Paris Agreement realization (even under the assumption that it will be signed by all countries) and understanding the dangers that sudden climate change brings; with this paper a radically new technology Seawater Steam Engine (SSE) is presented, which could completely reorient “high carbon economy” into “green economy” and it would...

Radical new technology Seawater Steam Engine presented in this book is a scientific and technological breakthrough with the hopes of stopping climate change. New technology can simultaneously produce energy and drinking water, using only 3 natural forces: Renewable energy sources (RES), Seawater and Gravity. In the next 15-30 years with this techno...

Given that the first industrial revolution was based on Steam Engine (coal as energy source), and the second on oil and electricity, where both these revolutions are actually "high carbon" revolutions, it is logical to expect that the third industrial revolution should be based on systems of renewable energy sources (RES), in order to minimize the...

Currently, the most suitable technology for storing relatively large amounts of solar energy is hydro energy (pumped storage hydroelectricity (PSH)). Given the problem of intermittent solar energy and the inability to ensure a continuous energy supply to customers throughout the year, this chapter analyzes the integration of solar (photovoltaic or...

This paper presents the artificial water inflow created by the photovoltaic (PV) or solar thermal (ST) generator which pumps it into the upper water/energy storage of pump storage hydroelectric (PSH) for continuous green energy production. Formulas have been derived for the calculation of artificial water inflow created by the PV and ST generator,...

Inherent characteristics of renewable energy sources (RES)-based electricity generation systems are intermittency and non-controllability. Electric power systems (EPS), mostly based on RES, where solar and wind energy prevail, cannot provide continuous energy supply to consumers without energy storage. In this way electric energy storage (EES) has...

Since the main problem of continuous energy supply from photovoltaic (PV) power plant is intermittence and inability to provide continuous energy supply, this paper proposes its hybridization with hydro energy, or with pump storage hydroelectric (PSH) as a possible solution. This creates a new type of sustainable hybrid power plant which can work c...

This paper presents the characteristics of a power plant that combines renewable energy sources (RES), that is, a photovoltaic (PV) power plant and pump storage hydroelectric (PSH), to achieve sustainable production of green electric energy equal to that of conventional energy sources. The proposed solution does not produce CO 2 and does not signif...

Održivi razvoj postao je prioritet u svim područjima, s osobitim naglaskom na očuvanja prirodnih resursa i smanjenje utjecaja na okoliš, stvaranjem što manje otpadnih materijala, odnosno njihovog ponovnog korištenja. Upotreba prirodnih zeolitnih materijala u građevnom materijalu, efikasno smanjuje štetno djelovanje nastalo utjecajima iz okoliša. Pr...

This paper analyzes a possibility of upgrading hydroelectric plant (HEP) with solar photovoltaic (PV) generator.

An inherent characteristic of renewable energy sources (RES)-based electricity generation systems is intermittency and non-controllability. Therefore, the prerequisite for a more significant use of RES within the energy system is the corresponding capacity of Electric Energy Storage (EES). The existing storage of Hydro Electric Power (HEP) is sugge...
