IAEI Magazine As a state electrical inspector, a typical day can be anything but typical. From code enforcer to code interpreter, problem solver to referee, to public relations representative, it can be challenging to keep track of the many hats one needs to wear! And while some hats are more weathered than others, they all get their fair share of use.
Electrical Contractor Electricity is not the only risk electrical contractors face. It is imperative to understand the fallout and other potential hazards that ECs encounter when working with electricity. Here is a helpful refresher on injuries that may happen to electrical contractors and a reminder of how severe such injuries can be.
Consulting-Specifying Engineer The water heater selection process is not overly complicated, but it is much easier when the design engineer has a comfort level with the players (e.g., design team, owner, local energy utility, original equipment manufacturer, etc.) and choices involved. The mechanical engineer’s ultimate responsibility when sizing a water heater is to provide the owner with a selection that meets specific needs while also working within the limitations of the building.
Windpower Engineering & Development The American wind industry has stayed resilient through a difficult year, with a positive outlook for development in the years ahead. However, in order to continue to grow and thrive throughout this crisis, owners and operators cannot afford to be complacent around fire risk. A high-profile fire can not only devastate current projects, but also jeopardize the prospects of future development across the industry – and this risk only grows as turbines get bigger and move into more remote sites on- and offshore.
Safety+Health Naturally, outdoor workers – including those who respond to wildfires – are most impacted, both directly (from the fires themselves) and indirectly (from smoke and fine, airborne particles dispersed by the fires). However, workers in commercial buildings and office locations near wildfires also face risks.
TechXplore As in people, aging plays out differently from one battery to another, and it's next to impossible to measure or model all of the interacting mechanisms that contribute to decline. As a result, most of the systems used to manage charge levels wisely and to estimate driving range in electric cars are nearly blind to changes in the battery's internal workings.
CleanTechnica I wrote about the newest US Solar Market Insight Report this morning to provide an update on US solar power capacity added in the first half of 2020, including in relation to other energy sources. However, there’s much more to cover in the report, so let’s go through some of those charts again as well as other ones.
EDN LED-based lighting for general illumination was first introduced about 20 years ago. As LEDs became more and more prevalent, concerns began to develop about the magnitude of lumen and chromaticity shift, and at an even more basic level, how should these attributes be measured?
