The Impact

Energy security improvement is often presented as a co-benefit of climate policies. This paper evaluates this claim. It investigates whether climate policy would improve energy security, while accounting for the difficulties entailed by the many-faceted nature of the concept and the large uncertainties on the determinants of future energy systems. A multi-dimension analysis grid is used to capture the energy security concept, and a database of scenarios allows us to explore the uncertainty space. The results, focusing on Europe, reveal there is no unequivocal effect of climate policy on all the perspectives of energy security. Moreover, time significantly matters: the impact of climate policies is mixed in the short term and globally good in the medium term. In the long term, there is a risk of degradation of the energy security. Lastly, we examine the robustness of our results to uncertainties on drivers of economic growth, availability of fossil fuels and the potentials and low-carbon technologies, and find that they are sensitive mainly to fossil fuels availability, low carbon technologies in the energy sector and improvements in energy efficiency.

Abstract. In the present Part 1 of a two-part paper, we formulate and study a simple Coupled Climate–Economy–Biosphere (CoCEB) model. This highly idealized model constitutes the basis of our integrated assessment approach to understanding the various feedbacks involved in the system. CoCEB is composed of a physical climate module, based on Earth's energy balance, and an economy module that uses endogenous economic growth with physical and human capital accumulation. We concentrate on the interactions between the two subsystems: the effect of climate on the economy, via damage functions, and the effect of the economy on climate, via control of greenhouse gas emissions. Simple functional forms of the relation between the two subsystems permit simple interpretations of the coupled effects. The CoCEB model is used to evaluate hypotheses on the long-term effect of investment in emission abatement, and on the comparative efficacy of different approaches to abatement. In this paper, we consider investments in low-carbon technologies. Carbon capture and storage (CCS), along with deforestation reduction, will be dealt with in Part 2. The CoCEB model is highly flexible and transparent; as such, it allows one to easily formulate and compare different functional representations of climate change mitigation policies. Using different mitigation measures and their cost estimates, as found in the literature, one is able to compare these measures in a coherent way. While many studies in the climate–economic literature treat abatement costs merely as an unproductive loss of income, this paper shows that mitigation costs do slow down economic growth over the next few decades, but only up to the mid-21st century or even earlier; growth reduction is compensated later on by having avoided negative impacts of climate change on the economy.

Significance The latest World Economic Outlook 2019 (WEO) from the International Energy Agency (IEA), published on November 13, suggests that achieving emissions targets will require gas to be a transition fuel, not a lasting solution. This will reduce investment in long-term projects involving combined cycle gas turbines and gas infrastructure. Impacts Growing concern about the emissions damage from increased gas use will encourage the development of alternative low-carbon technologies. Less investment in gas projects could create energy deficits unless renewable energy capacity and electricity grid construction increase. Impetus will grow to develop large carbon capture and storage (CCS) projects.

‘Other low-carbon technologies’ examines other low-carbon technologies, and sees how they fare against those already discussed in previous chapters. These are the renewables: tidal, wave, and geothermal power; and the low-carbon technologies of nuclear power and carbon capture. The contribution from tidal and wave power is small, with only a few tidal stream and underwater wave devices under development, and that the power from geothermal sources is potentially large, but difficult to extract. The deployment of nuclear power has been affected by concerns over its safety, the disposal of its waste, and its cost. By 2050, the total generation from all renewables and nuclear power could be close to 90 per cent of current global demand. While capture at fossil-fuel power plants looks uncompetitive, air capture through reforestation and through using chemical absorbers might remove 10 per cent of the emissions of carbon dioxide and help the world to be on target to achieve net-zero emissions.

Low Carbon Technologies

To overcome the negative environemental impact of the actual power system, an optimal description of quasi-static electromagnetics relying on a reversible interpretation of the Faraday’s law is given. Due to the overabundance of carbon-free energy sources, this description makes it possible to consider an evolution towards an energy system favoring low-carbon technologies. The management for changing is then explored through a simplified linear-programming problem and an analogy with phase transitions in physics is drawn.

Interruptions in electricity supply may have a series of failures that can affect banking, telecommunications, traffic, and safety sectors. Due to the two-way interactive abilities, Smart Grid allows consumers to automatically redirect on failure, or shut down of the equipment. Smart Grid technologies are the costly ones; however, due to the mitigation of possible problems, they are economically sound. Smart grids can't operate without smart meters, which may easily transmit real-time power consumption data to energy data centers, helping the consumer to make effective decisions about how much energy to use and at what time of day. Smart Grid meters do allow the consumer to track and reduce energy consumption bills during peak hours and increase the corresponding consumption during minimum hours. At a higher level of management (e.g., on the level of separate region or country), the Smart Grid distribution system operators have the opportunity to increase the reliability of power supply primarily by detecting or preventing emergencies. Ukraine's energy system is currently outdated and cannot withstand current loads. High levels of wear of the main and auxiliary equipment of the power system and uneven load distribution in the network often lead to emergencies and power outages. The Smart Grid achievements and energy sustainability are also related to the energy trilemma, which consists of key core dimensions– Energy Security, Energy Equity, and Environmental Sustainability. To be competitive in the world energy market, the country has to organize efficiently the cooperation of public/private actors, governments, economic and social agents, environmental issues, and individual consumer behaviors. Ukraine gained 61 positions out of 128 countries in a list in 2019 on the energy trilemma index. In general, Ukraine has a higher than average energy security position and lower than average energy equity, and environmental sustainability positions. Given the fact that the number of renewable energy sources is measured in hundreds and thousands, network management is complicated and requires a Smart Grid rapid response. Keywords: economic development, Smart Grid, electricity supply, economic and environmental efficiency.

Inefficient and non-environmentally friendly absorbent production can lead to much resource waste and go against low carbon and sustainable development. A novel and efficient Mg-Fe-Ce (MFC) complex metal oxide absorbent of fluoride ion (F−) removal was proposed for safe, environmentally friendly, and sustainable drinking water management. A series of optimization and preparation processes for the adsorbent and batch experiments (e.g., effects of solution pH, adsorption kinetics, adsorption isotherms, effects of coexisting anions, as well as surface properties tests) were carried out to analyze the characteristics of the adsorbent. The results indicated that optimum removal of F− occurred in a pH range of 4–5.5, and higher adsorption performances also happened under neutral pH conditions. The kinetic data under 10 and 50 mg·g−1 were found to be suitable for the pseudo-second-order adsorption rate model, and the two-site Langmuir model was ideal for adsorption isotherm data as compared to the one-site Langmuir model. According to the two-site Langmuir model, the maximum adsorption capacity calculated at pH 7.0 ± 0.2 was 204 mg·g−1. The adsorption of F− was not affected by the presence of sulfate (SO42−), nitrate (NO3−), and chloride (Cl−), which was suitable for practical applications in drinking water with high F− concentration. The MFC adsorbent has an amorphous structure, and there was an exchange reaction between OH− and F−. The novel MFC adsorbent was proven to have higher efficiency, better economy, and environmental sustainability, and be more environmentally friendly.
