This paper presents an analysis technique for investigating the effects of gyroscopic couples on the behaviour of a large vertical axis wind turbine mounted on a floating semi-submersible vessel. Equations of motion in 6 degrees of freedom are formulated in the frequency domain. Time domain...

The worldwide demand for renewable energy is increasing rapidly because of the climate problem, and also because oil resources are limited. Wind energy appears as a clean and good solution to cope with a great part of this energy demand. In Denmark for example, 20% of the electricity is produced...

Depending on what one reads, the cost of solar photovoltaic energy systems (solar PV systems) has already reached parity with grid produced electricity or, at the other extreme is far from parity. This leaves potential end users who are considering the installation of solar PV systems confused...

Energy can be produced from mixing waters with different salinity in reverse electrodialysis (RED). Technological improvements make RED gaining momentum as a technically viable option for baseload renewable energy generation. In this paper a model is presented for three different RED...

This paper provides an overview of the costs of concentrating solar power (CSP) deployed internationally and estimates of what these costs are expected to be in Australia, both for trough and tower technologies. When an analysis is made of how to improve the efficiency of a CSP plant, there is...

In addition to the high financial cost of energy resources required to meet the rising demand for electricity consumption in Kuwait, the negative environmental impact of fossil fuel is increasing. Hence, the objective of this paper is to determine the economic feasibility and viability of...

The integration of grid-connected PV systems into buildings or public areas is one of the most usual applications of the photovoltaic solar energy in developed countries and it is being highly promoted by several European governments. In this paper it has been evaluated the photovoltaic...

In this paper we first make a review of the past annual production of electricity and the cumulative installed capacity for photovoltaic (PV) and concentrating solar power (CSP) technologies. This together with the annual costs of PV modules and CSP systems allows us the determination of the...

The efficient selection of a wind turbine at a given site is presently limited by the developer's knowledge of what turbines are available on the market, and their inability to test and compare available turbine designs before investing. Poor turbine selection results in a financially...

Australia possesses the highest average solar radiation of any continent in the world, but solar energy in total contributes less than 1% to Australia’s primary energy consumption. This study intends to assess whether solar photovoltaic (PV) is really a sustainable option for Australia’s...
