Solar panels are a good alternative to fossil fuels. However, despite their numerous advantages, their most important limitation is dependence on environmental conditions. To solve this problem, energy storage systems are used with solar panels. To set a fixed output voltage requires designing a strong switching system to use stored energy when solar energy drops below the required value due to environmental conditions, and to store it in a storage system when there is a surplus of solar energy.
Climate change is accepted as the biggest challenge for the European Union (EU) and for this reason being a climate-neutral continent by 2050 is a priority for Europe. Deploying more renewables, increasing energy efficiency and electrification are the most important tools serving to this policy. With the support of innovation, renewable energy sectors could be more effective in climate change mitigation and adaptation measures. In this study, the two most mature renewable energy sectors; solar photovoltaic and wind energy in European countries are examined.
Algal biodiesels have emerged as a promising renewable energy source with numerous advantages over conventional fossil fuels. This paper provides a comprehensive overview of diverse production processes, drawbacks, and benefits of the algal biofuel production process while also critically assessing the potential gaps in the field. With a plethora of advantages like cost-effectiveness, nutrient cycling, yield benefits, sustainability, and versatility required for commercial usage, several challenges are yet to be addressed for effective implementation.
This study seeks the view of ten school principals on the pathways of incorporating environmental education into the school curriculum in South Africa.
Shows behavioural and physiological responses to habitat change
This Article supports SDG 3 sequencing hepatitis C virus genomes in west Africa, showing the level of genotypic diversity and measuring the response to direct-acting antivirals.
The article analyzes the effect of women's engagement in agriculture (WEA) on income inequality in sub-Saharan Africa (SSA) using data from 1991-2018.
Human health, in the coming decades (and already in some “front-running” regions), is in peril. Although some authorities warn that over-stating such risks can induce paralysis and despair, under-stating them will not generate the intense action that is required. The impact of climate change on the Earth system is now so significant that the next ice age will likely be delayed by at least 50,000 years [201]. If humans do not rapidly change their collective behavior, then this may be their most enduring legacy. It is hoped that this chapter makes a small contribution to SDG3.
Knowledge of biological diversity is a major source of innovation. Collective intellectual property of traditional knowledge by Indigenous peoples and local communities is an important source of innovation and product development. This article investigates collective intellectual property systems on the traditional knowledge of Aspalathus linearis, also known as rooibos—an endemic plant from South Africa which is the basis of an important herbal tea industry. The article discusses how collective action and self-organization can generate collective intellectual property systems; indigenous peoples and local communities can develop these systems to protect their IP; how these systems can promote social justice and a more equitable distribution of benefits but can be sources of dispute between socio-economic groups and communities and can reproduce historical inequalities and power asymmetries.
Previous studies have shown that people with HIV are at an increased risk of non-communicable diseases, this systematic review and meta-analysis collates data from 188 studies done in 21 sub-Saharan Africa countries and shows that people with HIV have an increased incidence of multiple NCDs, including hypertension, diabetes, and cervical cancer. Although more research is needed, this results highlight the need for improved treatment and prentative approaches to minimise the risk of people with HIV also developing non-comminicable diseases. Good health and wellbeing should not solely be focused on HIV managment; this study shows the growing risk of other diseases that have to be mitigated.
