Abstract

The simple action of filling a glass of water at home generates a greenhouse gas emission elsewhere, because it is necessary to spend electricity to treat the water, make it potable and then pump it to the point of consumption. These daily activities, seemingly clean, need electric energy and they carry out a human-induced greenhouse gas emission. Generation of electricity has a significant effect on the inventory of emissions and environmental impacts due to the large differences in the power generation sources used. This paper aims to shed light on the methodological challenge and develop a necessary simplified methodology to illustrate the importance of the power generation mix in urban greenhouse emissions. The electrical mix is a figure that expresses the carbon emissions associated to the electrical power generation, so it is an indicator of the suitability of the sources used for electrical power production. The smaller the mix, the higher is the contribution of low carbon emission sources. The methodology is explained, applying it to Madrid, assessing the greenhouse gas emission per kWh of electricity generated. The proposed estimation covers emissions of CO 2 equivalent (KgCO 2eq ), including the equivalence between each greenhouse gas and carbon dioxide considering a prevalence of 100 years.

Abstract

Emerging economies account for a fast-growing share of the global energy market. In particular, energy use in China has become significant from both economic and environmental standpoints. This trend makes it necessary to balance the need for affordable, reliable electricity supply with the need to ensure that the power infrastructure is environmentally sustainable. As such, this paper presents a multi-dimensional pinch analysis (MDPA) of the power generation sector in China; the analysis considers five key indices: carbon footprint, energy return on investment (EROI), water footprint, land footprint, and risk to humans. By simultaneously quantifying five different indices under a common methodological framework, we are able to coherently assess the impact on five different environmental concerns. This approach provides a more complete picture of the true environmental impact of China's power sector. This information can thus help policymakers avoid the problem of shifting environmental impacts to other domains, which can occur when the analytic procedure used focuses on a single environmental dimension.

Abstract

The energy transition driven by the need of a deep decarbonization to limit the world temperature rise requires coordinated actions across the whole energy sector. Among other measures, the strong development of renewable energy sources in the power sector is gaining momentum in different parts of the world. The possibility of producing low-carbon electricity leads to a renovated interest in increasing electricity penetration in final sectors, especially in transport and buildings heating. However, a large share of renewable electricity comes from non-dispatchable sources, notably wind and solar PV, and their daily and seasonal variability needs to be matched with the demand profiles of those sectors. In particular, the charge of electric vehicles shows a relatively constant demand on a seasonal basis while attention must be paid on the daily operational logic to fully exploit available power from solar and/or wind. On the other hand, the operation of heat pumps for building heating shows a strong seasonality that may be an issue in countries that have a larger renewable production during summer. This research work is focusing on this specific issue, with the aim of improving the common practice of evaluating energy consumption and emissions on an annual basis, thanks to a detailed analysis based on hourly time-step, both for the electricity generation mix and for the heat pumps demand. To increase the significance of the results, different countries across Europe have been analyzed and compared.

Abstract

Thailand needs to avoid the high-carbon growth path of many developed countries and, instead, take a low-carbon growth path. A green low-carbon growth path is in Thailand's own interest as it can simultaneously tackle local environmental degradation, global climate change, and energy security challenges. It can also position Thailand as a regional leader in green, sustainable growth. Green low-carbon growth in Thailand could focus on the following four pillars: 1) maintaining rapid economic growth while adjusting the country's economic structure toward a less energy, and carbon-intensive economy; 2) achieving greater urbanization while shifting toward green livable low-carbon cities; 3) meeting the huge thirst for energy while transforming the energy sector toward one of high energy efficiency and widespread diffusion of low-carbon technologies; and 4) improving quality of life while shifting toward a resource-efficient and sustainable lifestyle.
