A hybrid wind/solar/diesel stand alone system optimisation for remote areas in Algeria
While Algeria has an important potential of wind and solar energies, their share in the primary energy supply is relatively low compared to the fossil energy. In this paper, we propose to carry out a techno–economical study of a hybrid stand alone system in order to draw the attention to the feasibility of such systems. For this purpose, sites of Hassi–R'mel and Adrar have been ...

Wind & solar energy and nature conservation
Climate change and the degradation of ecosystems and biodiversity cannot be solved in isolation. Land and marine ecosystems play a crucial role in the climate system, capturing roughly half of carbon dioxide emissions generated by human activities (UNEP, 2009). Protecting biodiversity preserves ecosystem services that are important for regulating the climate and helping us to adapt to the impacts ...

Energetic and exergetic assessment of solar and wind potentials in Europe
This paper deals with a physics–based assessment of renewable energy potential in Europe, particularly solar and wind energy sources, using two literature models. A sensibility analysis with the weather data is first done. Actual temperature, pressure, relative humidity, global radiation and wind speed data are employed to develop energy and exergy maps for Europe, based on iso–areas of land–use. ...

Alternative scenarios of the utilisation of renewable energy sources in small prefectures: a case study in Lasithi Prefecture, Greece
The sector of Renewable Energy Sources (RESs) is growing very fast, with many innovations and applications becoming a reality. The continuous reduction of natural resources has forced all policymakers to turn to alternative energy sources. The total energy (oil and electricity consumption) consumed in the prefecture of Lasithi during the years 1997?2002 in correlation with the RES exploitation ...

Technical and economic evaluation and feasibility study of biomass energy
The urgent need for the reduction of harmful environmental impact during energy production necessitates research for efficient, economically feasible energy production processes. The wide spreading of energy coming from renewable energy sources with low or zero emission levels, such as wind energy, solar energy, hydro-energy and biomass, is the most promising solution to the problem. This study ...

The changing structure of the renewable industry – implications for a green transition to sustainable energy
This paper investigates the transition process from carbon to renewable energy. How a transition occurs, whose values are solicited and whose voices are listened to will determine the contours of the future economy. Section 1 will briefly discuss the current contours of global energy. Section 2 will discuss the large international oil companies (IOCs) as a possible obstacle to the transition to ...

Optimal environmental benefits of utilising alternative energy technologies in Jordan
With rapid population growth and increase in industrial activities, more energy is consumed, resulting in environmental pollution and economic difficulties. Therefore, the need for utilising renewable energy resources has emerged. Although Jordan does not have adequate fuel supplies (90% of its crude oil is imported), it is gifted with alternative resources. Because of the political and ...

Size optimisation of hybrid wind-PV power generation systems for remote rural areas
Electrical power generation with renewable energies, such as wind and solar, plays an important role in the electrification of remote rural areas. Since there are always seasonal and synoptic variations in wind and solar resources, a hybrid system, consisting of both wind and solar energy, may be more reliable and economical than a single energy system: this is because either energy can ...

Renewable Energy Market in Indonesia
The development of renewable energy in Indonesia has stalled in recent years, especially wind and solar PV power. By the end of 2018, cumulative installed solar and wind capacity in Indonesia just reached 136MW, which is at a relatively low level compared with other Southeast Asian countries. It is a recognized fact that 2019 was the year of Vietnam’s renewable energy explosion, with a new ...

Structure-preserving dynamical model and distributed stabilisation of electricity infrastructures with renewable energy resources
This paper introduces a module-based approach to modelling and controlling electricity infrastructure with a high penetration of distributed renewable energy resources. Each energy-converting component is defined as a module and is represented in terms of its local variables and the interaction variables between the module and the transmission network. The structure of the electricity ...

Eco-Brella: prototype development of the umbrella as harvester of solar and wind energies
The familiar umbrella has been redesigned for power harvesting from renewable energy sources resulting in the Eco-Brella . Several engineering technologies are utilised: aerodynamics for fin design, mechatronics for power management, materials for thermoelectric and solar film, CAD for the layout, and heat transfer for human comfort. The result is a sustainable design capable of harvesting ...

Optimal scheduling and operation of hybrid biomass/wind/PV energy system for rural areas
In this paper, a hybrid energy system consisting of biomass, wind, solar photovoltaic (SPV) and battery, is proposed. The sources are operated to deliver energy at optimum efficiency. An optimisation model is developed to supply the available energy to the loads according to the priority. It is also proposed to maintain a fair level of energy storage to meet the peak load demand together with ...

Critical review of energy options
Short term measure for dealing with energy crisis is reducing consumption by: 1) improving the efficiency of all energy consuming machines; 2) eliminating the wasteful use of energy. Renewable sources of energy such as solar, wind, tidal, waves, etc., do make a significant contribution to demand for energy but they are unlikely to meet the ever increasing consumption. Long term measures may ...

Renewable energy to grow 400% by 2040
Increasing competitiveness of wind and solar energy will see renewables grow by over 400% by 2040 if current trends continue, according to new predictions by BP. The oil and gas giant said that renewables would provide around 14% of primary energy by that time, and account for over half the global increase in power generation, which will rise by a third. It expects China to be the ...

Many hamsters: how the EU can enable private firms to provide renewable energy
This paper investigates the energy investment needs of the European Union (EU), including renewable energy. Europe currently has little or no economic growth, and interest rates are expected to rise. Given the state of many EU countries' economies, this is a good time to encourage investment because - according to Keynesian economics - extra spending can stimulate economic activity. The current ...
