Abstract The results of calculations presented in the article show the effectiveness of the transition from diesel power plants using imported fuel to installations using renewable energy sources – solar cells and wind generators. Studies have shown that for Primorsky Krai such a transition is justified, despite significant capital costs, and the payback period for new power plants based on renewable energy sources is about 8 years.

Abstract The aim of this research is to find a solution that can contribute to the more widespread use of electric vehicles and, through development, promote the use of renewable energy sources. It aims to eliminate the disadvantages of electric vehicles, such as self-discharge, stationary charging and limited range. The focus is mainly a solar-powered solution, since small solar cells have already been implemented on the commercially available Nissan Leaf model to solve similar problems but with very little or no improvement. Encouraged by this attempt I have engineered a larger, more useful auxiliary solar cell system to improve the range of these vehicles.

Renewable energy sources have both renewable and sustainable properties and the utilization of renewable energy sources is a continuously developed alternative. One of the technologies that can utilize renewable energy is polycrystalline solar cells. Solar cells are technology that converts sunlight energy into electrical energy. This technology is very potentially applied in Indonesia that has a tropical climate, but the main problem of this system is the power instability generated. The power produced relies heavily on the intensity of the sun received by the solar panels. The intensity of the solar radiation received by the solar panels can be maximised by installing solar panels, with a precise tilt angle. In research acquired the relationship between irradiation and current correlates of R = 0.7251. From the correlation value above indicates that there is a strong link and is directly proportional between irradiation and the current obtained. The acquired Model needs to be seen its accuracy, in which case it will be used Mean Absolute Percent Error So it is obtained by 26.5%. This indicates that the model is good enough.

Nowadays, Product Integrated Photovoltaic (PIPV) plays a major role in renewable energy sources, particularly for the infantry soldiers and defense industry. During war field, soldiers having various harms such as very cold temperature and some region like hot weather. Hence, in this risky process they cannot always be having the tools with battery for communication equipment and still in case they are prepared with batteries, it will be a big burden for them. Thus, to overcome this difficulty, a light weight wearable solar device being designed especially for the warrior. The proposed research contains a design, which is a portable-charging unit that utilizes flexible solar cells. The flexible solar cells are tested in different environment to find out the best arrangement and design for soldier‟s bag.

Energy Justice

Over 90% of Uganda's power is generated from renewable sources. Standardised Implementation Agreements and Power Purchase Agreements create a long-term relationship between Generating Companies and the state-owned off-taker guaranteed by Government. The COVID-19 pandemic and measures to curb the spread of the virus have triggered the scrutiny and application of force majeure (FM) clauses in these agreements. This article reviews the FM clauses and considers their relevance. The authors submit that FM clauses are a useful commercial tool for achieving energy justice by ensuring the continuity of the project, despite the dire effects of the pandemic. Proposals are made for practical considerations for a post-COVID-19 future which provides the continued pursuit of policy goals of promoting renewable energy sources and increasing access to clean energy, thus accelerating just energy transitions.
