South Africa is been faced with erratic power supply, resulting in persistent load shedding due to ageing in most of its coal-fired power plants. Associated with generating electricity from fossil fuel are environmental consequences such as greenhouse emissions and climate change. On the other hand, the country is endowed with abundant renewable energy resources that can potentially ameliorate its energy needs. This article explores the viability of renewable energy using the strengths, weaknesses, opportunities and threats (SWOT) analysis approach on the key renewable potential in the country. The result indicates that geographic position, political and economic stability and policy implementation are some of the strengths. However, Government bureaucratic processes, level of awareness and high investment cost are some of the weaknesses. Several opportunities favour switching to renewable energy, and these include regional integration, global awareness on climate change and the continuous electricity demand. Some threats hindering the renewable energy sector in the country include land ownership, corruption and erratic climatic conditions. Some policy implications are suggested based on the findings of the study.

Energy Potential

In Australia the future demand for energy is predicted to increase rapidly. Conventional energy resources soaring prices and environmental impact have increased the interest in renewable energy technology. As a result of that the Australian government is promoting renewable energy; such as wind, geothermal, solar and hydropower. These types of energy are believed to be cost-effective and environmentally friendly. Renewable energy availability is controlled by climatic conditions such as solar radiation, wind speed and temperature. This paper aims to assess the potential of renewable energy resources, in particular wind and solar energy in an Australian subtropical region (Central and North Queensland) namely, Gladstone, Emerald, Rockhampton, Yeppoon, Townsville, and Cairns. Analysis is done by using the latest statistical state of Queensland energy information, along with measured data history of wind speed, solar irradiations, air temperature, relative humidity, and atmospheric pressure for those sites. This study has also shown that national assessments of solar and wind energy potential can be improved by improving local climatic data assessments using spatial databases of Central and North Queensland areas.

AbstractRenewable energy (RE) plays an increasingly important role in the economy of almost every country in the world. In order to examine the state of renewable energy (RE) in Mazowieckie Voivodeship (Poland), a literature review was carried out, anonymous surveys were conducted, a SWOT (Strenghts, Weaknesses, Opportunities, Threats) and TOWS analysis were carried out and the potential of RE in Mazowieckie voivodship was estimated. The total capacity of all installations is equal to 712 MW. In recent months, number of prosumers have increased to 11,742 in the Voivodeship, and the capacity of their installations is estimated at 66 MW. Simplification of legal regulations and educating society is strongly recommended. Respondents in the survey and SWOT analysis on the future of the energy sector in Mazowieckie Voivodeship show that solar energy (35.5% of respondents) and wind energy (24.5% of respondents) have the greatest chances for the development. Development of the RE sector in the Voivodeship means new jobs, both in this sector and around it. Significant RE potential together with large project financing possibilities may cause Mazowieckie Voivodeship to be a leader in RE production in Poland. It is this Voivodeship (with its capital Warsaw) that can serve as an example of the energy transformation towards 100% RE.

Abstract The development of the marine renewable energy and offshore aquaculture sectors is susceptible to being affected by climate change. Consequently, for the long-term planning of these activities, a holistic view on the effects of climate change on energy resources and environmental conditions is required. Based on present climate and future climate scenario, favourable conditions for wind and wave energy exploitation and for farming six marine fish species are assessed using a suitability index over all European regional seas. Regarding available energy potential, the estimated changes in climate do not have direct impacts on the geographic distribution of potential regions for the energy industry (both wind and wave based), that is they pose no threat to this industry. Long-term changes in environmental conditions could however require adaptation of the aquaculture sector and especially of its exploitation areas. Opportunities for aquaculture expansion of the assessed species are identified. Possibilities for co-location of these activities are observed in the different climate scenarios. The evaluation of potential zones for the exploitation of marine renewable energy resources and offshore aquaculture represents a stepping-stone, useful for improving decision-making and assisting in the management of marine economies both in the short-term and in the long-term development of these sectors.

In the last years, the European Union has developed and set a several environmental policies whose imposes an obligation on Member States to implement specific actions, including incorporating climate change considerations into SEA and EIA processes. One of major environmental challenges facing most developing countries is that of global climate change. The aim of the research was to obtain a comprehensive review of existing SEA and EIA practical approaches for renewable energy installations in the aspect of adaptation to climate change with specific reference to Polish projects. Both SEA and EIA procedures implemented in Poland and other countries was introduced with the intent of factoring in potential risk to the environment by future large-scale project developments such as the construction of power plants, roads, or dams. The paper consist the initial recognition of available data of the current experience and level of implementation climate change impact and adaptions into local procedures. Preliminary results suggest that the additional funding should be given for climate change adaptation in the energy sector, especially in renewable energy projects, as well as specific interventions for climate-adapted energy systems should be targeted in order to fill the gap in RES sector and spur sustainable energy development.
