To mitigate the effects of climate change, the massive deployment of renewable energies is a key challenge in the near future. While for wind power plants, repowering is common practice to increase the energy yield, the early replacement of old photovoltaic (PV) modules with newer, more...

The contribution of fluctuating wind and solar energy sources to the German electrical energy demand has increased from 12% up to 40% within the last 10 years and leads to higher infrastructure requirements due to the different spatiotemporal characteristics of wind and solar energy generation....

With the increasing amount of building renovations in Austria, the potential increases for replacing conventional national gas heating systems with heat pumps (HP) and thereby reduce CO2 emissions particularly when combined with solar photovoltaics (PV). The Austrian subsidization scheme for HP...

Effectively mitigating the increasing energy demand sector emissions is seriously considered in China. Under the continuous motivation of the Chinese government, the cumulative installed solar PV capacity in China has occupied 32.63 % of the global in 2019. Unfortunately, a large amount of...

In this paper, we explore the development of financing and subsidies for renewable energy in three fossil-fuelled European countries: Poland, the Netherlands, and the United Kingdom. Financing for renewable energy is an existing arena involving multi-actor activities and practices that develop...

A decarbonized global energy sector is expected to need cumulative investments in the tens to hundreds of trillions of dollars between now and 2050. Due to its size, the current climate-business environment is therefore prone to corruption risks. Yet such corruption risks are rarely explored...

A weather-driven model is used to investigate the requirements for the backup generation (annual energy, power capacity and flexibility) in a power system with different penetrations of wind, solar photovoltaics, and hydroelectricity. The impact of interannual variability is assessed by using 26...

Photovoltaic solar systems are widely used as a renewable energy resource worldwide due to the numerous negative impacts of the conventional-depleted energy resources. In the context of the Middle East, the United Arab Emirates has been a pioneer in regulating renewable energy and setting annual...

It is necessary to increase the use of renewable energy sources to supply the world's energy demand to mitigate the harmful effects of climate change. Many countries have incorporated the use of solar energy on a large scale. However, the use of photovoltaic (PV) systems at the residential level...

The combined scheduling of hydro, thermal and hybrid energy (i.e., wind and solar) is attracting more and more attention nowadays. This paper explores the contribution of renewable energy sources in the traditional hydrothermal scheduling problem in order to overcome the prevailing issues like...
