Abstract
The purpose of this study is to identify the most relevant renewable energy technologies for buildings and to assess the effectiveness of their implementation in the long term for Kuwait. Methods of analogies and comparisons were used to determine the features of energy efficiency based on the technologies under study. The study proposes the methodological approach to assessing the effectiveness of the introduction of renewable energy technologies, determining the direction of increasing the energy efficiency of buildings and the investment efficiency of introducing these technologies. Renewable energy efficiency analysis for buildings in Kuwait confirms that solar energy systems have been the most widely available for widespread use of solar energy over the past three years. An increasing level of energy efficiency with a decrease in the notional cost of increasing energy savings is characteristic of solar collectors with booster reflectors. The proposed model for assessing the level of energy saving provides an opportunity for economic justification of introducing renewable energy technology in buildings.
Highlights
Climate warming is the main threat to all countries in the world
This study proves the high impact of the choice of renewable energy technology, especially Hybrid Photovoltaic-Wind Systems (HPVWS), flat plate thermosiphon units (FPTUs), and Solar collectors with booster reflectors (SCBR), and energy storage on the cost of 1% of the building’s energy savings, and allows one to determine the extent of this impact
A significant limitation of this study is the general assumptions of the technical characteristics of the technologies being introduced, which may differ in capacity, service life, energy storage volume, cost of assembly depending on the characteristics of the building, etc
Summary
Climate warming is the main threat to all countries in the world. The Risk Report of the World Economic Forum, which took place in January 2019 in Davos, emphasized five risks related to climate change out of ten possible risks for the future development of world civilization. Humanity has only 12 years to eliminate them. This requires coordinated action on this issue by all countries of the world, without exception. It is necessary to maintain the level of climate warming within 1.5 degrees (according to the terms of the Paris Climate Agreement), which has not yet been achieved. According to the forecasts of the World Bank experts, by 2050, 140 million of the world’s inhabitants may become internally displaced due to climate change [1]
