Post-Covid-19 Energy Transition Strategies: Even Reaching 100% Renewable in Ecuador by 2055 is not Enough to Face Climate Change Issue

Climate change policy: IPCC consensus is not enough.

Intergovernmental Panel on Climate Change (IPCC) consensual scientific knowledge on climate change and its effects is to some extent the known truth, but not necessarily the entire truth. Consensual scientific knowledge is only a minimum common denominator for thousands of scientists of different disciplines and thousands of studies that, due to their multiplicity, heterogeneity, and complexity...

Combating Climate Change: The Role of Renewable Energy and Energy Efficiency

Climate change and its possible impacts on the environment and socio-economic systems now constitute the most important environmental problem facing mankind in the 21st century. Climate change will increase poverty and hardship, endanger food security, destabilize economies, decrease food and water and create social insecurity in many countries and undermine our goals for achieving sustainable ...

Energy Efficiency Is Not Enough, Energy Proportionality Is Needed!

Due to the energy consumption/resource utilization characteristics of todays centralized DB servers, the fastest configuration is also the most energy-efficient one. Extensive use of SSDs alone cannot enable a fundamental change of this overall picture, because the storagerelated energy consumption is typically only a little fraction of the overall energy budget. Even, when this storage-related...

Tackling HIV in MENA: Talk Is Not Enough–It Is Time for Bold Actions: A Response to Recent Commentaries

DRAFT: Scalability Bugs: When 100-Node Testing is Not Enough

We highlight the problem of scalability bugs, a new class of bugs that appear in “cloud-scale” distributed systems. Scalability bugs are latent bugs that are clusterscale dependent, whose symptoms typically surface in large-scale deployments, but not in small or mediumscale deployments. The standard practice to test large distributed systems is to deploy them on a large number of machines (“rea...
