The future role of stationary electricity storage is perceived as highly uncertain. One reason is that most studies into the future cost of storage technologies focus on investment cost. An appropriate cost assessment must be based on the application-specific lifetime cost of storing electricity. We determine the levelized cost of storage (LCOS) for 9 technologies in 12 power system applications from 2015 to 2050 based on projected investment cost reductions and current performance parameters.
Entrepreneurship is widely argued to be critical for alleviating extreme poverty. However, research on this topic is characterized by diverging perspectives regarding poverty alleviation and remains fragmented across various research domains. This review examines 77 leading academic journals over the period 1990 to 2017 and identifies over 200 articles on entrepreneurship and poverty alleviation.
SDG 8 calls for promoting 'sustained, inclusive and sustainable economic growth, full and productive employment and decent work for all’. Even as it highlights the importance of labour rights for all, it also makes visible some significant tensions. We note, for example, that despite many critiques of narrow economic measures of growth, the focus here remains on GDP and per capita growth. This is problematic, we argue, because the GDP productive boundary excludes much of social reproductive work.
The pollution of the marine environment by solid wastes, either directly introduced into the sea or discharged into the oceans from rivers or pipelines, is considered from the perspective of both their impacts and their regulation. The waste materials covered include dredged material, particulate wastes from sand/gravel extraction, and land reclamation, and industrial wastes including mining wastes, munitions, and plastics/litter.
