Assessing the extent of evidence available relating to the impact of solar energy for households (HHs) in developing countries, surveys are reviewed focusing on the impact of pico‐photovoltaic (e.g., solar lanterns) or solar home systems (SHS) on rural HHs and directly related economic activities of their occupiers. Ninety‐eight documents have been analyzed. Areas of enquiry have included the impact of small individual solar photovoltaic systems on different facets of the life of HHs' occupiers: their education, health, finance, livelihoods, and social relations.

The Bali Province Technical Guidelines (written in Indonesian) for Implementing Green Buildings in the Context of Clean Energy represent a collaborative effort between the Bali Provincial Government, Global Building Performance Network (GBPN), and support from CORE Udayana. Developed through extensive studies and analysis from November 2021 to June 2022, the guidelines engage stakeholders from the Provincial Government Bali, Professional Expert Team, universities, associations, private sectors, and professionals in building and clean energy.

Heat pumps are relatively simple appliances. They share similar components to refrigerators and air conditioners and effectively move an external source of heat to where it is needed, such as in buildings for heating or the production of hot water. Their key value is efficiency; for each unit of electricity consumed to operate them, they produce multiple units of usable heat. Because of this, they require much less energy input for a similar heating outcome compared to combustion technologies, making them naturally cleaner and generally cost effective to run.

The Samarinda City Technical Guidelines represent a strategic initiative aligned with the city's development goals, as outlined in Mayor Regulation No. 55 of 2021. These guidelines meticulously consider the potential savings and additional benefits achievable through the implementation of energy and water-efficient measures, aiming to significantly reduce carbon emissions in buildings. Spearheaded by the Samarinda City Government, this effort reflects a commitment to fostering an environmentally friendly and sustainable urban landscape.
