Energy innovation in Latin America: R&D effort, deployment, and capability accumulation

Ibero-America, just as the rest of the world, faces an increasing urgency to transform existing energy systems. In the past, incentives to develop energy systems were induced mainly by changes in demand (derived from industrialization and urbanization) and by price shocks in fuels. Diversification of energy sources followed a growing need of use of particular energy forms. For developing countries, innovating in energy systems meant fundamentally gaining control over natural resources and moving away from primary, export-oriented enclaves into industrial integration, as well as improving energy security. Today, however, environmental constraints and the pressing need to reduce energy poverty forge additional challenges and set new directions to change the ways in which we use and produce energy. Improving current technologies along the same trajectory is simply not enough. Fundamental changes must take place in our economic systems in order to combine energy efficiency with low-carbon, sustainable energy sources, for which new abilities and solutions need to be targeted.energy innovation; Latin America

Rescue US energy innovation

President Trump has proposed severe cuts to US government spending on energy research, development and demonstration, but Congress has the ‘power of the purse’ and can rescue US energy innovation. If serious cuts are enacted, the pace of innovation will slow, harming the economy, energy security and global environmental quality. The Trump Administration has proposed a 57% reduction in US government investments in energy research, development and demonstration (RD&D) at the Department of Energy (DOE), from US$3.8 billion allocated for fiscal year 2017 (FY2017) under the continuing resolution to US$1.6 billion in the FY2018 request (unless otherwise stated, all dollar figures are given in constant 2015 US dollars). These severe reductions, if enacted by Congress, would reduce the pace of US energy-technology innovation, ultimately harming the US economy, energy security, environmental quality and the capacity of the world’s second largest emitter of greenhouse gases to do its share in reducing the emissions that are driving global climate change. This abdication of leadership would adversely affect not just US interests but global interests as well

Experience with Carbon Taxes and Greenhouse Gas Emissions Trading Systems

Carbon taxes and emissions trading systems (ETSs) to limit emissions of greenhouse gases (GHGs) are increasingly common. At the end of 2015, 17 GHG ETSs were operational in 55 jurisdictions, and 18 jurisdictions collected at least one carbon tax. This paper assesses the performance of carbon taxes and ETSs with respect to environmental effectiveness (reduction of emissions regulated by the instrument), cost-effectiveness (marginal abatement cost), economic efficiency, public finance, and administrative issues. Data on emissions subject to carbon taxes are rarely reported. We estimate the taxed emissions for 17 taxes in 12 jurisdictions from 1991 through the end of 2015. All 17 taxes have reduced emissions relative to business-as-usual. Six of the jurisdictions actually reduced emissions, although in at least three of those jurisdictions the reductions appear to be due to other policies. The small sizes of reduction in almost all 17 cases are partially due to the low tax rates; the modest and uncertain changes in tax rates over time; and the limited response of taxed sources, such as fossil fuels, to price changes. Actual emissions declined for at least six of 10 ETSs. Other policies and developments, such as the 2009 recession, contributed to the reductions, but estimates of the share of the reduction attributable to the instrument are rare. All of the ETSs have accumulated banks of surplus allowances and most have implemented measures to reduce these banks. On average, the marginal cost of compliance is substantially lower for ETSs than carbon taxes. ETS experience has been shared bilaterally and via dedicated institutions. As a result, most ETSs have increased the share of allowances auctioned; adopted declining emissions caps; specified future caps and floor prices several years into the future; shifted to benchmarking for free allowance allocations to emissions-intensive, trade-exposed (EITE) sources; reduced accessibility to foreign offset credits; and established market stability reserves. By contrast, there is little evidence of shared learning and virtually no change to the design of carbon taxes. We found no jurisdiction that routinely tracks the taxed emissions. Very few jurisdictions regularly assess the effectiveness of the tax in achieving emission reductions. Additionally, adjustments to the tax rate often are unpredictable after an introductory period of three to five years. Both instruments reduce emissions, but ETSs have performed better than carbon taxes on the principal criteria of environmental effectiveness and cost-effectiveness. Many jurisdictions have implemented both a carbon tax and a GHG ETS, and every jurisdiction that has adopted either instrument has also implemented other policies. More research is needed to improve the design of both instruments and their interaction with non-market-based carbon policies because the use of multiple instruments produces complex interactive and distributional effects. While economically inefficient, market-based policies should be supplemented by non-market-based policies to ensure sustained political support

Tackling U.S. energy challenges and opportunities: preliminary policy recommendations for enhancing energy innovation in the United States

The report offers preliminary recommendations for near-term actions to strengthen the U.S. effort to develop and deploy advanced energy technologies. The report comes as the Obama Administration and the 111th U.S. Congress face enormous challenges and opportunities in tackling the pressing security, economic, and environmental problems posed by the energy sector. Improving the technologies of energy supply and end-use is a prerequisite for surmounting these challenges in a timely and cost-effective way, and this report elaborates on how policy can support develop of these important energy technologies

Tackling U.S. energy challenges and opportunities: preliminary policy recommendations for enhancing energy innovation in the United States

The incoming Obama Administration and the 111th Congress face enormous challenges and opportunities in tackling the pressing security, economic, and environmental problems posed by the energy sector in the United States and worldwide. Improving the technologies of energy supply and end-use is a prerequisite for surmounting these challenges in a timely and cost-effective way. Accelerating the development and deployment of advanced energy-supply and end-use technologies will require a comprehensive strategy integrating efforts from invention to deployment, including strong leadership, alignment of policy incentives, consistency of policies, and a long-term view. In the following sections we outline our preliminary recommendations for near-term actions to strengthen the U.S. effort to develop and deploy advanced energy technologies. Our analysis is continuing, and we will be publishing long -term policy recommendations later this year. The budget recommendations in this paper are only for fiscal year (FY) 2010. They represent minimum levels based on ramping up from FY 2008 levels where such increases are most needed. They do not take into account the amounts provided in the recently approved economic recovery package

In-use vehicle emissions in China: Beijing study

China's economic boom in the last three decades has spurred increasing demand for transportation services and personal mobility. Consequently, vehicle population has grown rapidly since the early 1990s, especially in megacities such as Beijing, Guangzhou, and Tianjin. As a result, mobile sources have become more conspicuous contributors to urban air pollution in Chinese cities. Tianjin was our first focus city, and the study there took us about two years to complete. Building upon the experience and partnership generated through the Tianjin study, the research team carried out the Beijing study from fall 2007–fall 2008. Beijing was chosen to be our second focus city for several reasons: it has the largest local fleet and the highest percentage of the population owning vehicles among all Chinese cities, and it has suffered from severe air pollution, partially due to the ever-growing population of on-road vehicles

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy

Diving into the vertical dimension of elasmobranch movement ecology

Knowledge of the three-dimensional movement patterns of elasmobranchs is vital to understand their ecological roles and exposure to anthropogenic pressures. To date, comparative studies among species at global scales have mostly focused on horizontal movements. Our study addresses the knowledge gap of vertical movements by compiling the first global synthesis of vertical habitat use by elasmobranchs from data obtained by deployment of 989 biotelemetry tags on 38 elasmobranch species. Elasmobranchs displayed high intra- and interspecific variability in vertical movement patterns. Substantial vertical overlap was observed for many epipelagic elasmobranchs, indicating an increased likelihood to display spatial overlap, biologically interact, and share similar risk to anthropogenic threats that vary on a vertical gradient. We highlight the critical next steps toward incorporating vertical movement into global management and monitoring strategies for elasmobranchs, emphasizing the need to address geographic and taxonomic biases in deployments and to concurrently consider both horizontal and vertical movements
