“…This is in line with our results where rooftop PV contributes significantly to meeting household's electricity demand, even leading to certain households becoming "energy positive" (see Figure S5). However, PV generation is very sensitive to price developments (both PV and grid-electricity), and as shown in Gernaat et al (2020), a 50% decrease in PV costs could lead to a 3-fold increase in generation.…”

“…The model includes a dynamic representation of residential rooftop PV including their potential, investments, and dispatch (Gernaat, de Boer et al 2020). The regional potential of rooftop PV surface area is determined by relating projections of floorspace area to roof area, corrected for factors affecting suitability such as shading, architectural features and orientation.…”

The residential sector currently accounts for one fifth of global energy use and corresponding greenhouse gas emissions, largely driven by increasing demand for space heating and cooling. Climate change mitigation action requires these to reduce, but the exact decarbonization strategies and their heterogeneity is unclear. We use a regional recursive dynamic energy system model with an explicit representation of residential energy use and building stocks to explore the contribution of this sector in long-term decarbonization pathways. The projections show that in a 2˚C scenario, global heating demand is expected to decrease from current levels by 18% and 64% by 2050 and 2100, respectively. However, due to increasing affluence in warmer regions, cooling demand is expected to increase by 112% and 201% respectively. Yet, direct residential emissions are almost eliminated by 2100. This is achieved by combining increased envelope efficiency and advanced heating technologies in a synergistic manner, where the adoption of high efficiency heating and cooling reduces the need for increased insulation, and vice versa. By combining these measures with rooftop PV, the net energy demand of many household types approaches zero. The exact residential sector strategies vary across different regions, depending on local climate, socio-economic, and building stock characteristics.

“…For electricity generation, this has been investigated 18 – 23 , but not for vehicles. Although global IEMs are the main tool for identifying optimal climate change mitigation pathways, they generally do not offer the same level of technological detail as national models do 10 , 15 , 16 , 24 which may limit their ability to identify optimal solutions across the range of options available in the real world. Further, while some integrated assessments account for materials used in electric power plants 25 , 26 , others point out the importance of considering efficient use of resources within integrated climate scenarios 27 .…”

Pricing indirect emissions accelerates low—carbon transition of US light vehicle sector

Large–scale electric vehicle adoption can greatly reduce emissions from vehicle tailpipes. However, analysts have cautioned that it can come with increased indirect emissions from electricity and battery production that are not commonly regulated by transport policies. We combine integrated energy modeling and life cycle assessment to compare optimal policy scenarios that price emissions at the tailpipe only, versus both tailpipe and indirect emissions. Surprisingly, scenarios that also price indirect emissions exhibit higher, rather than reduced, sales of electric vehicles, while yielding lower cumulative tailpipe and indirect emissions. Expected technological change ensures that emissions from electricity and battery production are more than offset by reduced emissions of gasoline production. Given continued decarbonization of electricity supply, results show that a large–scale adoption of electric vehicles is able to reduce CO2 emissions through more channels than previously expected. Further, carbon pricing of stationary sources will also favor electric vehicles.

“…Grid-tied rooftop solar power can reduce the pressure on the power grid load at noon rush hours and decrease the burden of investment in the power system. However, development of PV rooftop power depends on regional characteristics [9]. Many grid-tied stalled, and new rooftop solar power projects in 2021 are not yet permitted to connect to the local utility grid and install the bi-directional meters [28].…”

Study on Performance of Rooftop Solar Power Generation Combined with Battery Storage at Office Building in Northeast Region, Vietnam

At present, renewable energy sources are considered to ensure energy security and combat climate change. Vietnam has a high potential for solar power development, especially in the central region and the southern region. However, the northeast region has the lowest solar radiation value, so it can cause difficulty for rooftop solar power investment. In this paper, the study results analyze the financial efficiency of the grid-tied rooftop solar power system with battery storage and compared it to the grid-tied rooftop solar power system without battery storage. The experimental data of a grid-tied solar power system with battery storage at an office building in the northeast region of Vietnam is collected to evaluate the system’s operation performance in real conditions. The study results present that the financial efficiency of rooftop grid-tied power project with and without storage is viable since the benefit-cost ratio (B–C) is larger than one, and internal rate of return (IRR) and net present value (NPV) are positive. However, the grid-tied rooftop solar power system with storage is not quite feasible in case of changing the electricity selling price and investment cost even though the grid-tied solar power system using the storage device can operate more flexibly. The payback period of the grid-tied solar power system with storage is 6.2 years longer and the total profit is nearly 1.9 times lower than the solar power system without battery storage due to the difference in the price of the inverters and the battery. In contrast, the grid-tied solar power system without battery storage shows better financial efficiency but strongly depends on the operation of the utility grid.
