‘Why do we need renewables?’ describes the dangers of fossil fuels and explains the importance of renewable energy as an alternative. It shows that the use of fossil fuels causes global warming and climate change, leading to widespread concern, and also to a growing realization of the harm caused by the air pollution from coal burning and from internal combustion engines in cars and lorries. These threats are causing a switch away from fossil fuels to renewables that is gaining impetus from the growing awareness of the increased intensity and frequency of extreme weather seen in recent years. This transition is also being aided by the falling price of clean energy from renewables, in particular, solar and wind farms, which will become the dominant sources. The area of land or sea required for these farms is readily available, as are the back-ups required to handle their variability. Alternative supplies of low-carbon energy are examined. In the Paris Agreement in 2015, it was recognized that carbon dioxide emissions must reach net-zero by 2050 to avoid dangerous climate change.

The discovery of oil in Pennsylvania in 1859 was a relatively inconspicuous precursor to what would become an epic shift into the modern age of energy. At the time, the search for “rock oil” was driven by a perception that lighting fuel was running out. Advances in petrochemical refining and internal combustion engines had yet to occur, and oil was more expensive than coal. In less than 100 years, oil gained worldwide prominence as an energy source and traded commodity. Along similar lines, electricity in the early 1900s powered less than 10% of the homes in the United States. Yet, in under a half a century, billions of homes around the world were equipped to utilize the refined form of energy. Estimates indicate that roughly 85% of the world’s population had access to electricity in 2014 (World Bank, n.d.b). For both petroleum and electricity, significant changes in energy use and associated technologies were closely linked to evolutions in infrastructure, institutions, investment, and practices. Today, countless decision-makers are focusing on transforming energy systems from fossil fuels to low carbon energy which is widely deemed to be a cleaner, more sustainable form of energy. As of 2016, 176 countries have renewable energy targets in place, compared to 43 in 2005 (Renewable Energy Policy Network for the 21st Century [REN21], 2017). Many jurisdictions are also setting increasingly ambitious targets for 100% renewable energy or electricity (Bloomberg New Energy Finance [BNEF], 2016). In 2015, the G7 and G20 committed to accelerate the provision of access to renewables and efficiency (REN21, 2016). In conjunction with all of the above priorities, clean energy investment surged in 2015 to a new record of $329 billion, despite low, fossil fuel prices. A significant “decoupling” of economic and carbon dioxide (CO2) growth was also evident, due in part to China’s increased use of renewable energy and efforts by member countries of the Organization for Economic Cooperation and Development (OECD) to foster greater use of renewables and efficiency (REN21, 2016).

AbstractThis paper uses data for 134 countries for the period 1960–2010 to document an energy ladder that nations ascend as their economies develop. On average, economic development results in an overall substitution from the use of biomass to energy sourced from fossil fuels, and then increasingly towards nuclear power and certain low-carbon modern renewables such as wind power. The process results in the carbon intensity of energy evolving in an inverse-U manner as per capita incomes increase. Fossil fuel-poor countries climb more quickly to the low-carbon upper rungs of the national-level energy ladder and so typically experience larger reductions in the carbon intensity of energy as they develop. Leapfrogging to low-carbon energy sources on the upper rungs of the national-level energy ladder is one route via which developing countries can reduce the magnitudes of their expected upswings in carbon dioxide emissions.

Northeast Asia is the most developed region in Asia with large energy demand, and plays an important role in the global economic development. Northeast Asia has been facing severe challenges in ensuring energy security, protecting the environment, and coping with climate change, because of their high dependency on fossil fuels and imports of oil from outside the region, and inverse distribution between energy resources and demand. In order to actively respond to climate change, promote the transition to low-carbon energy and sustainable development in the region, achieve the grand purpose of economic prosperity, social progress and ecological protection, this study is conducted with a focus on power grid interconnection in Northeast Asia. Based on the historical energy and power data in Northeast Asia, this paper studies the development trends of energy and power demand in future by combining qualitative and quantitative methods. Considering the distribution of clean energy bases, this paper proposes an energy interconnection scheme in Northeast Asia with high clear energy penetration scenario. To form the Asia-Europe energy interconnection, the construction of the Asia-Europe interconnection channels is briefly analyzed in this paper.

Ozone depletion and acid rain are problems that have some similarity to climate change – both are caused by the emission of gases that circulate widely, though neither has the scope and scale of the climate problem. But it is encouraging that both problems are well en route to solution. Our main institutions for addressing climate change are the IPCC (Intergovernmental Panel on Climate Change) and the UFCCC (United Nations Framework Convention on Climate Change), with the latter producing the Kyoto Protocol in 1997 and the 2015 Paris Agreement. Cap and Trade and regulatory policies have been used more widely than any others for tackling the climate problem so far. Replacement of fossil fuels by low-carbon energy technologies offers the greatest hope for a complete solution, and is within sight: policies need to be focused on making this a reality.

Non-technical summary A small benefit of the disastrous COVID-19 pandemic has been the temporary reduction in greenhouse gas emissions. Therefore, this paper asks: what strategies can return people to work without returning to the old high-emissions economy? How can we modify the old economic system to reduce environmental impacts while rebuilding employment? Technological change, such as replacing fossil fuels with renewable energy (RE), is necessary but, in an economy that's growing, unlikely to be sufficiently rapid to avoid dangerous climate change. Degrowth in physical consumption, especially by the ‘rich’ 10%, towards a steady-state economy, is needed as well as low-carbon jobs.

For this feature, I have had the pleasure of reviewing 122 papers submitted to SPE in the field of offshore facilities over the past year. Brent crude oil price finally has reached $75/bbl at the time of writing. So far, this oil price is the highest since before the COVID-19 pandemic, which is a good sign that demand is picking up. Oil and gas offshore projects also seem to be picking up; most offshore greenfield projects are dictated by economics and the price of oil. As predicted by some analysts, global oil consumption will continue to increase as the world’s economy recovers from the pandemic. A new trend has arisen, however, where, in addition to traditional economic screening, oil and gas investors look to environment, social, and governance considerations to value the prospects of a project and minimize financial risk from environmental and social issues. The oil price being around $75/bbl has not necessarily led to more-attractive offshore exploration and production (E&P) projects, even though the typical offshore breakeven price is in the range of $40–55/bbl. We must acknowledge the energy transition, while also acknowledging that oil and natural gas will continue to be essential to meeting the world’s energy needs for many years. At least five European oil and gas E&P companies have announced net-zero 2050 ambitions so far. According to Rystad Energy, continuous major investments in E&P still are needed to meet growing global oil and gas demand. For the past 2 years, the global investment in E&P project spending is limited to $200 billion, including offshore, so a situation might arise with reserve replacement becoming challenging while demand accelerates rapidly. Because of well productivity, operability challenges, and uncertainty, however, opening the choke valve or pipeline tap is not as easy as the public thinks, especially on aging facilities. On another note, the technology landscape is moving to emerging areas such as net-zero; decarbonization; carbon capture, use, and storage; renewables; hydrogen; novel geothermal solutions; and a circular carbon economy. Historically, however, the Offshore Technology Conference began proactively discussing renewables technology—such as wave, tidal, ocean thermal, and solar—in 1980. The remaining question, then, is how to balance the lack of capital expenditure spending during the pandemic and, to some extent, what the role of offshore is in the energy transition. Maximizing offshore oil and gas recovery is not enough anymore. In the short term, engaging the low-carbon energy transition as early as possible and leading efforts in decarbonization will become a strategic move. Leveraging our expertise in offshore infrastructure, supply chains, sea transportation, storage, and oil and gas market development to support low-carbon energy deployment in the energy transition will become vital. We have plenty of technical knowledge and skill to offer for offshore wind projects, for instance. The Hywind wind farm offshore Scotland is one example of a project that is using the same spar technology as typical offshore oil and gas infrastructure. Innovation, optimization, effective use of capital and operational expenditures, more-affordable offshore technology, and excellent project management, no doubt, also will become a new normal offshore.

In response to global climate change, Canada is transitioning towards a low-carbon economy and the need for policy approaches that are effective, equitable, coordinated, and both administratively and politically feasible is high. One point is clear; the transition is intimately tied to the vast supply of ecosystem services in the boreal zone of Canada. This paper describes four contrasting futures for the boreal zone using scenario analysis, which is a transdisciplinary, participatory approach that considers alternative futures and policy implications under conditions of high uncertainty and complexity. The two critical forces shaping the four scenarios are the global economy’s energy and society’s capacity to adapt. The six drivers of change are atmospheric change, the demand for provisioning ecosystem services, the demand for nonprovisioning ecosystem services, demographics, and social values, governance and geopolitics, and industrial innovation and infrastructure. The four scenarios include: (i) the Green Path, where a low-carbon economy is coupled with high adaptive capacity; (ii) the Uphill Climb, where a low-carbon economy is instead coupled with low adaptive capacity; (iii) the Carpool Lane, where society has a strong capacity to adapt but a reliance on fossil fuels; and (iv) the Slippery Slope, where there is both a high-carbon economy and a society with low adaptive capacity. The scenarios illustrate the importance of transitioning to a low-carbon economy and the role of society’s adaptive capacity in doing so. However, they also emphasize themes like social inequality and adverse environmental outcomes arising from the push towards climate change mitigation.

AbstractTo help avoid the most catastrophic effects of climate change, society needs to achieve net-zero greenhouse gas emissions by mid-century. Wind energy provides a clean, renewable source of electricity; however, improperly sited wind facilities pose known threats to wildlife populations and contribute to degradation of natural habitats. To support a rapid transition to low-carbon energy while protecting imperiled species, we identified potential low-impact areas for wind development in a 17-state region of the central U.S. By combining maps of sensitive habitats and species with wind speed and land use information, we demonstrate that there is significant potential to develop wind energy in the Great Plains while avoiding significant negative impacts to wildlife. These low-impact areas have the potential to yield approximately 1,099-1,832 GW of wind capacity. This is equivalent to 10-18 times current U.S. installed wind capacity. Our analysis demonstrates that ambitious low-carbon energy goals are achievable on sites with minimal risk of wildlife conflict.

Abstract. The article examines the features of sustainable development processes in Ukraine. In particular, the works of scientists on the issues of sustainable transformations of the economy, the problems of establishing a mechanism for the transition to the use of renewable energy sources and reducing carbon dioxide emissions are analyzed. The basic principles of legislative regulation of the processes of sustainable transformation in the context of Ukraine’s integration into the international model of sustainable development according to the UN Framework Convention on Climate Change are studied. The research objective is to study the mechanism of implementation of sustainable transformations in the economy of Ukraine, identification of the main problems of low-carbon strategy establishment in the context of harmonization of international and state legislation and identification of effective mechanisms for financing sustainable development processes. During the research, methods were used, such as: the dialectical method and methods of analysis and synthesis — to carry out a comparative analysis of legislation that regulates the processes of sustainable development, ways to implement a low-carbon strategy, study trends in carbon emissions in Ukraine; statistical method — to analyse the targets for changing the greenhouse gas emissions of Ukraine in 2020—2030 and the proposed target for 2050; structural and logical analysis — to study effective mechanisms of financing the processes of sustainable development in Ukraine, identify the ways of sustainable development projects funding. In general, the article reveals a number of problems that Ukraine faces as a signatory to the Kyoto Protocol. The main tools of the country’s transition to a low-carbon strategy have been identified. The economic mechanisms to ensure the fulfillment of the country’s obligations under the Kyoto Protocol have been studied. Possible ways of financing the processes of sustainable transformation are considered, among which, in particular, we can highlight the scheme of «green» investments. Keywords: sustainable economic development, Framework Convention on Climate Change, Kyoto Protocol, low carbon economy, mechanism for financing sustainable development.
