Global Growth in Offshore Wind Turbine Technology

Due to the commissioning of floating wind units, the latest technological developments, significant growth, and improvements in turbines, developments in offshore wind power capacity are estimated to increase faster than in the last two decades. The total installed offshore wind power capacity, which is currently 35 GW, is predicted to be approximately 382 GW by 2030 and approximately 2,002 GW by 2050. For this reason, attempts are proposed to lower levelised cost of electricity (LCOE) for offshore wind power generation more than for other energy sources. In this study firstly, the global growth in the nominal capacity and size of offshore wind turbines over the last twenty years is examined. Then, the effects of this increase in nominal capacity and size on the LOCE, total installation cost (TIC), and turbine capacity factor are investigated. In parallel with this development, the changes in distance to shore and water depth for installation offshore wind power plants are reviewed according to the years. In addition, the effects of this global growth on wind farm capacity, turbine-specific power capacity, number of turbines per GW, and area needed per GW are investigated and discussed in detail.

China's economy will struggle to halt secular slowdown

Significance Comparisons with two formerly fast-growing Asian neighbours, Japan and South Korea, suggest that China will continue to slow for another decade. Analysis of global growth trends over 50 years points to a strong force of ‘regression to the mean’, meaning that continued high-speed growth is statistically unlikely. Impacts Continued Chinese economic slowing will reduce global demand for resources such as iron ore and coal. Achieving productivity growth will require deepening reforms to increase the role of the market, the private sector and competition. World Bank economists emphasise that imposing stricter financial discipline is a key step to enhancing market-based productivity gains.

United States - China Relations: Prospects during Xi - Biden Tenure

Bilateral relations between China and the United States have become strategic in nature with implications to the rest of the world. Both have been engaging and competing on a number of issues in the recent times. While both seek security and stability so as to pursue their respective national interests, they differ on the way they pursue these. While engagement has been the dominant theme in the previous administrations, since late Trump, bilateral relations exhibited tensions on a number of issues including what China considered to be its core interests. Chinas agenda of keeping a low profile has been changed to accomplish something and it intends to occupy the centre stage in the long-term. The election of Joseph Biden as the President of the US coincided with the ongoing reassessments on the bilateral relations as well as coming to the fore of tensions on a number of fronts with China. The spread of COVID-19 pandemic, decline in global growth rates, disruptions in supply chains, and the growing uncertainty have only further exacerbated the US - China relations. Below is a review of the bilateral relations in the recent times by eliciting cooperative and competitive trends between China and the US. It is argued that the US - China relations are undergoing major shifts due to the tensions even as both are for ushering in strategic stability. Chinas perceptions at the leadership level, media and academic levels are outlined in brief to suggest that relations with the US are exhibiting tensions on a number of issues that pose challenges and opportunities for other countries.

Global growth trend in fisheries and current situation in Turkey

In recent years the most salient change in the global food sector has been witnessed in the range of fisheries. Due to the gravity of fishery, particularly in meeting the needs of an adequate and balanced diet, its total share in production, consumption and trading has been on the rise on a global scale. The aim of this study is to detect the factors impinging upon growth trend and foreign trade of global fishery sector. To that end, data from 1990-2017 period of 10 countries meeting 72% of global fisheries and data from Turkey have been employed. In this study panel data analysis method has been applied by using 11 cross-section data and 28-time series. Importation and exportation models have thus been set. An increase by 100% in production of fisheries climbs exportation share by 15% and degrades importation share by 1%. 1-unit increase in income heightens importation by 8 units. Slowness in the growth rate of production of fisheries can be associated with supplying the vast majority of total production by only a few select countries thus threatening global exportation of fisheries. Turkey and relevant countries could gain exportation advantage by conducting a better analysis of their existing potential.

Prospects for African economies in 2022

Significance However, this recovery remains below global growth for the second consecutive year, further widening global income disparities and possibly undermining crucial domestic spending well into the medium term.

Multi-Asset Value Payoff: Is Recent Underperformance Cyclical?

Recent value factor underperformance has called into question whether the value factor payoff is cyclically low, or if there are more structural challenges. We use a new approach to explore a link between the well-known macroeconomic exposures of traditional asset classes and those of value premia in a multi-asset context, focusing on country equities, bonds, and currencies in developed markets. Taking advantage of the cross-country inflation and growth expectations implicit in every value portfolio, we derive the net inflation and real growth characteristics embedded in each asset class carry portfolio at each point in time. Our analysis provides several insights: (1) Multi-asset value payoff is only weakly related to the global business cycle. (2) However, we find that the payoff to value portfolios is strongly linked to relative growth and inflation expectations across countries. (3) Over the last decade, we find that cheaper assets have had much lower net relative macro exposures compared to earlier time periods. This characteristic coincides with the period of unconventional central bank policies designed to lift global growth after the Global Financial Crisis (GFC).

Evidence of a recent decline in UK emissions of hydrofluorocarbons determined by the InTEM inverse model and atmospheric measurements

National greenhouse gas inventories (GHGIs) are submitted annually to the United Nations Framework Convention on Climate Change (UNFCCC). They are estimated in compliance with Intergovernmental Panel on Climate Change (IPCC) methodological guidance using activity data, emission factors and facility-level measurements. For some sources, the outputs from these calculations are very uncertain. Inverse modelling techniques that use high-quality, long-term measurements of atmospheric gases have been developed to provide independent verification of national GHGIs. This is considered good practice by the IPCC as it helps national inventory compilers to verify reported emissions and to reduce emission uncertainty. Emission estimates from the InTEM (Inversion Technique for Emission Modelling) model are presented for the UK for the hydrofluorocarbons (HFCs) reported to the UNFCCC (HFC-125, HFC-134a, HFC-143a, HFC-152a, HFC-23, HFC-32, HFC-227ea, HFC-245fa, HFC-43-10mee and HFC-365mfc). These HFCs have high global warming potentials (GWPs), and the global background mole fractions of all but two are increasing, thus highlighting their relevance to the climate and a need for increasing the accuracy of emission estimation for regulatory purposes. This study presents evidence that the long-term annual increase in growth of HFC-134a has stopped and is now decreasing. For HFC-32 there is an early indication, its rapid global growth period has ended, and there is evidence that the annual increase in global growth for HFC-125 has slowed from 2018. The inverse modelling results indicate that the UK implementation of European Union regulation of HFC emissions has been successful in initiating a decline in UK emissions from 2018. Comparison of the total InTEM UK HFC emissions in 2020 with the average from 2009–2012 shows a drop of 35 %, indicating progress toward the target of a 79 % decrease in sales by 2030. The total InTEM HFC emission estimates (2008–2018) are on average 73 (62–83) % of, or 4.3 (2.7–5.9) Tg CO2-eq yr−1 lower than, the total HFC emission estimates from the UK GHGI. There are also significant discrepancies between the two estimates for the individual HFCs.
