Electricity demand is expected to surge, but homes could be doing more to support the grid. A new report suggests home energy upgrades like solar power, batteries and heat pumps can offset the electricity demand from data centers. It suggests that the grid will need 93 gigawatts of additional power by 2029 for data centers that are announced or currently under construction. Read more |

The Global Energy Alliance for People and Planet installs renewable energy in developing countries and wants to invest around $7.5 billion during its next five-year plan. The alliance, launched at global climate talks in 2021, has helped 30-plus countries to enhance electricity grids, set up battery storage and create jobs in the green economy. Founded by the IKEA Foundation, The Rockefeller Foundation and the Bezos Earth Fund, its partner roster has grown to include countries such as Britain and Denmark, the World Bank and private sector companies.

Engineers face a dilemma when selecting the optimal heat exchanger design: horizontal or vertical. Horizontal heat exchangers are less expensive to install, but they are highly dependent on temperature fluctuations. Meanwhile, vertical heat exchangers provide more stable results and do not depend on climate, but their installation requires drilling, which significantly increases costs. To determine which option is more efficient, researchers from the Autonomous University of Baja California and the Autonomous University of the State of Morelos in Mexico built numerical models of both heat exchangers, verifying their accuracy with real-world data.

Based on low, medium and high emissions scenarios, the U.S. will reduce greenhouse gas emissions 26%-41% in 2040 compared with 2005 levels. However, the pace of decarbonization will slow dramatically, partially due to recent and potential policy changes by Congress and the Trump administration. Under the high emissions scenario, Rhodium estimates that average annual U.S. GHG emissions reductions were 1.1% from 2005 to 2024. Read more

The topics of data-driven smart buildings and smart control have been emerging in research on smart buildings. A returning point of concern in the creation of a data-driven smart building is the need for metadata and how to encode such metadata. In data-driven smart buildings the metadata clarifies what such data measures and represents: the meta of data. This article critically reviews the nature of these metadata, while focusing on the different forms that these metadata take in the design and engineering of control systems. Download here

With the growth of data centers threatening to overload U.S. electricity grids, policymakers are taking a hard look at a tough-love solution: bumping them off grids during power emergencies. Texas moved first, as state lawmakers try to protect residents in the data-center hotspot from another deadly blackout, like the winter storm in 2021 when dozens died. Now the concept is emerging in the 13-state mid-Atlantic grid and elsewhere as massive data centers are coming online faster than power plants can be built and connected to grids. Read more
